The New Tascam DR-100mkII: Markedly Better


The original Tascam DR-100 stood out from the pack for being an extremely well equipped, compact portable digital recorder laden with useful features, like its dual XLR inputs and thumb-friendly level-adjustment dials. Even though it was a popular and well-regarded model, Tascam decided to push things further and make it even better. In a direct response to customer feedback, the DR-100mkII was recently introduced, and it’s loaded with a number of upgrades and additions. The end result is a powerful tool with more inputs that’s capable of recording cleaner and richer-sounding audio.

Outstanding among the improvements are its four built-in microphones and preamps. Both the forward-facing dual cardioid condensers and the pair of front-panel omnidirectional microphones were retooled to capture better-sounding recordings. The microphone preamps on the original DR-100 were often favored over competing products. However, Tascam made additional improvements to the preamps in the DR-100mkII, giving them more gain and a lower noise floor.  

A digital S/PDIF input was added to the DR-100mkII, which makes it possible to connect external digital signals. This gives you the option of using a higher-quality piece of equipment as the front end of your recording chain. For example, you can connect the optical S/PDIF output on the Sound Devices USBPre 2 to the new S/PDIF input on the DR-100mkII. The analog and digital circuitry on the Sound Devices USBPre 2 (preamps, limiters, converters, etc.) is of the highest caliber. Recording that signal directly into the DR-100mkII gives you all of the quality without any degradation. 

The all-important XLR input section of the DR-100mkII received two big updates, also. Locking mechanisms were added, which will prevent the cables from accidentally losing contact with the recorder. In addition, a switch was added to the bottom of the DR-100mkII, which enables you to change the XLR input sensitivity from mic level to professional line level. The XLR inputs are balanced, which will help you achieve premium, low-noise recordings.

All of the attributes that made the original DR-100 an attractive portable digital recorder are still intact. The new DR-100mkII can record high resolution 96 kHz 24-bit stereo WAV files, as well as record compressed MP3 files, from 32 to 320kb/s. There are two battery compartments on the DR-100mkII, one for the included Tascam rechargeable Li-ion battery (that can be charged through the built-in high speed USB 2.0 port) and another for AA batteries. The XLR inputs can provide condenser microphones with +48V of phantom power. A speaker is built in for monitoring and there’s an integrated tripod thread on the base for mounting. The housing is still made with rugged aluminum.

Both the DR-100 and the DR-100mkII share a feature that you don’t see on many compact portable recorders: They both have multiple 3.5mm outputs—a dedicated headphone output and a separate line-level output. They’re particularly useful for recording sound on an HDSLR video shoot. The dual outputs make it possible to connect headphones directly to the recorder for monitoring, and to connect the line-level output separately to the camera’s 3.5mm mic input (using an attenuated DSLR line to mic cable). This way you can actively adjust the headphone volume to your liking, while feeding the camera a constant audio level to record. 

B&H created a DR-100mkII kit for anyone who wants to exercise this method of recording sound for HDSLR shoots. The Tascam DR-100mkII On-Camera DSLR Audio Kit supplies you with all of the accessories required to mount the recorder to a camera shoe, and to connect its dedicated line-level output to the mic input on a camera. One of the benefits of this method is that you’re recording two copies of the audio: a high-resolution copy in the recorder and a second copy in the camera (albeit at the camera’s lower audio resolution). Another benefit is that it effectively gives your camera two XLR inputs, with headphone monitoring. The kit also includes a fluffy windscreen for outdoor recording, headphones and a 4GB SD card.

The improved inputs, preamps and microphones on the new DR-100mkII will benefit any kind of user, whether you need to record music, sound bites and interviews for journalism, podcasts or sound effects. No matter what your discipline, improved sound quality is always a welcome thing.

the playback speed seems to be slower than the actual recorded speed and also, the sound is "shakeing" on playback.

hello everyone

i want to record 2 external xlr mic at the same time with dr100 mkii. but from different source. So can i hear the sound while i'm recording from left and right channels separately? there will be two different sound and i have to check both left and right channels. is it possible to listen sepatately? Or is device going to let me hear just mix of the two channels?

Hi Ozkan -

You can monitor the stereo mix only.

Hi there,

I love using the TASCAM DR100– MK2 for interviews however, I recently purchased 2 x lav mics (Rode Smart Lav Plus) as well as a 3.5MM adapter (RODSC3) and breakout box (RODSC6) and I am not hearing any audio. In fact, no sound is coming through the mics whatsoever. I have switched the input to LINE 2, still nothing is getting picked up. 

What am I doing wrong? 

Unfortunately the Smartlav microphone is not designed for use with professional digital recorders like the Tascam DR-100MKII. There are 2 main reasons: 1. The Rode Smartlav is designed for use only with Android, or iOS devices like iPhones, iPads and Smartphones. 2. Since the microphone capsule runs on a very low voltage ( 1.5 volts), even if you were able to use adapter cables, volume will not be perceptible because a digital recorder like the Tascam DR-100MKII can only be used with microphones which capsules can handle mainly 24/48 volts power to activate the circuit.

I have a Tascam DR100. I am looking for a real good omni lav mic that would hook into it's XLR port and also to be used with my Sony wirelass bodypack set (UTX-B03 & UTXP03). I do a lot of documentary interviews and a lot of voiceover narration. Please advise good omni lav mic alternatives along with 10' and 25' XLR cables.

Thanks so much for the great intro to the DR-100 MKii. Based on your review, I asked around and found someone locally with this TASCAM dig recorder. However, I am trying to use my Rode videomic lavalier with it; even used the XLR adapter, but simply cannot get the Rode to work with the DR-100 - input either through side 3.5mm jack ("line 2") or through either XLR plug. Any notion what I am doing wrong? Or does this combination of Rode lav mic and Tascam digital recorder just not work? Thanks again! Russ

Hi Russ -

Is this the microphone?  It is designed for wireless bodypack transmitters only:

The RØDE Lavalier Microphone has a proprietary MiCon connection which allows you to select from a number of optional adapters, for use with virtually any wireless bodypack transmitter. 

Note! MiCon connection is proprietary. Requires optional adapter for use with wireless transmitters, preamplifiers, etc.

Yes, that's the microphone. It works very well with the iPhone/iPad.  I did purchase the Micon-5, 3-pin XLR adapter for the proprietary Rode connector, but the screw size is different - that of the XLR adapter is smaller than the screw end from the lavalier mic. The 3.5mm adapter DOES fit, but not the 3-pin XLR. Odd, as both are from Rode, and were sold to fit this Rode lav mic. Perhaps there's a connecter to the adapter that will step-down the size of this connector so that it will fit the micon-5, 3-pin xlr adapter?

Despite the great reviews of the DR-100 MKii, I'm considering other digital recorders if it's going to be this much trouble to get my Rode lab to work with it. Thanks for the reply, Mark!

I presently own the Tascam DR-100. I'm looking to do some recording of LP's and wondering if I can connect my turntable via the Line In jack (located on the side of the unit.



I am planning on buying this recorder for our wedding videography business but read a user comment saying that the internal microphones could not record audio if external microphones are being used at the same time. This seemed odd so I wanted to clarify whether this is correct.

Our plan is to use the built-in microphones to record ambient noise and to pair that with a wireless lav plugged into one of the inputs which will record the minister, speakers etc.

Any advice would be much appreciated.



I am a transcriptionist working on an audio recorded on this device. From your description, I think there would be fabulous sound. However, it's one of the worst audios I've ever worked with. First of all, there's a terrible hum/static sort of sound that makes it impossible to turn up the volume and obscures the voices. Some of the voices fade in and out. What might cause this? What can be done to prevent this? Is there something the recorder should sit upon that would help? Any advice in terms of getting a high quality recording the next time with this recorder would be appreciated.

Also, for this audio, he is recording a meeting where there are 13-15 participants. Is this recorder capable of getting what everyone says? If so, how can the recorder be situated best to pick up what everyone says? The audio now only picks up the voices of people nearest to it.

Any tips would be greatly appreciated. It sounds like he bought a fabulous recorder but...


I'm sure I am overlooking something fairly obvious here but..I am trying to record audio from a sound board and using a xlr cable plugged into the left xlr input. It works ok but I am only getting sound from the left side of my headphones or speakers when I put it on the computer. Is this because I need to have 2 xlr cables in both inputs to get audio from the left and right side? I was hoping to use one input for the soundboard audio and one for a wireless lav mic..but if I'm only going to get the audio coming from the right or left sides later..

Also is there a way to fix this in post for the files I already have?

Hi Jeff -

You can drag the mono left channel track to the right channel stereo track in you editor to effectively create a two track L/R mono mix.  Or you can correct this in the recorder before recording by dialing in the Microphone Input Setting from the Menu to "MONO".  When set to mono, the same signal will be sent to both right and left channels.

I am planning to use Tascam DR100 MKii with SD MixPre-D using the Line out from MixPre to Line in in Tascam. I know that Tascam offers both 4dB and -10dB line ins? I would like to go the pro way? How can I do this? Which cable should I use?


You would use the XLR inputs of the DR100 MKII. This would be the balanced connectors at +4db.

To connect the Sound Devices MixPre D to the Tascam DR100 MK II, you will need two xlr cables. You can find these XLR cables listed by length, at the following link.

Thanks for the great information on this recorder. I'm just getting into HDSLR video and am looking for a durable digital recorder. I don't anticipate recording more than two channels at a time. I'm currently using the Rode Videomic Pro as an external mic but anticipate adding more. Great sound, build quality, (relatively) small size and ease of use are the most important features to me, in that order. I'm looking at the DR100Mk.II, the new Nagra Lino and the Roland R26 as possible candidates. Do you have any recommendations as to what might best suit my needs?


Hello MikeD -

The Nagra and Roland products are excellent, but may be pricey for the beginner considering the Tascam DR100MKll offers you excellent mic preamps, awesome aluminum body construction and overall professional recording results that would be indistinguishable from the other products you mention.

I've been renting a Marantz PMD661, I'd like to own a recorder, this Tascam looks pretty good, and my new D600 gives me some better options for the camera's onboard backup track, monitoring, metering, etc. (I consider the external linear track the main)
Am I giving anything up on the Tascam over the Marantz? And also, if I wanted to just use the on camera tracks, does the Tascam work more or less like an HDSLR balance adapter...I think so, but there may be spec issues with preamp quality I dont know about...

A couple quick questions

Can one record from a computer through the usb?

I want to confirm that it doesn't solely record from one input at a time (uni, line, etc...). It's possible to simultaneously record from one xlr input, one mini jack, and both on-board mics? And will these be fused onto one track or output as 4 distinct stereo tracks?

Also, could you explain what it means to switch from mic to line input (i feel like i should understand that, but don't - one is balanced??)

thanks a bunch

i have just urchased a DR100 mk2 unit. The firmware version shown in information is 1.00 0025. Is this the current version, and if not where can I find the latest please?


I have a question about recording multiple tracks at a time, I want to record with a shotgun mic (with phantom power), a levalier mic, and also stereo ambient sound using internal mics simultaneously, but I want the option of adjusting levels in post so it should be recorded to separate tracks.

I notice the DR100mkii says "2-Channel Linear PCM Recorder" and the DR40 is a 4 track recorder, wats the difference? (tracks vs channels).

I understand I can do what I mentioned with the ZoomH4n, but the tascam looks like a better product overall, will I be able to do this with either the DR110 or DR 40? and also might the Olympus LS100 be a good or better option and why?

Thank you!

This is really useful information here, thank you kindly for this piece.  It is particularly insightful to me, a dude who purchased the original model in late '09, and am about to purchase some much-needed kit beefing-up, all B&H selections of course....

The first thing I noticed when shopping was this new "Mark II" model designation--which led me to reading this article--perhaps the only thing on the web that actually told me really just what was happening in the evolution of this recorder.  Of course the Biggest Draw to the DR-100 has always been the XLR's, and application of using the recorder in some semblence of a traditional film-style of shooting using two-system sound.  It seemed to be nearly a capable replacement for a Nagra 4.1 in my book...! albeit leaving a few things out along the way, but offering--well a whole lot for the loot.

In reading this piece, of course I would like to get a new Mark II (when did it go to Mark II anyway!?!), but I will just have to live with the original model ('cause it's paid for) but someday would like to move to the newer model.  The biggest obvious upgrade at first seemed those xlr locks, it is indeed unnerving to not have them when shooting with xlr inputs, that's for sure.  But the spdif I/O is also great idea (no a-to-d conversion--sure makes sense!!), and of course the line level xlr input setting is like a no-brainer and was identified as a real shortcoming when I first got it way back when.

And the mic pre-amp retooling sure seems a good idea, as the original unit is always wanting more gain, that's for sure.  A good shotgun plugged-in makes you see (ok, hear) that immediately, just so much more to work with.

But otherwise this piece has been pretty much a digital dream, so I'll just have to suffer on for the time being.  Have since picked up a DR-2d as well (and about to get another given recent price plummets), and both recorders work well together, swapping cards like some 70's key party or something.

The accessories I am now targeting include:  1) Strut STR-DR100 Audio Case for Tascam DR-100, a beautiful and protective idea for such a great device, looking better than the Porta-Brace versioin in my mind; 2) Rycote Portable Recorder Audio Kit for Tascam DR-100, what a setup!  Stupidly overpriced but hey it's Rycote, all just so darn good.... 3) Tascam BP-6AA External Battery Pack for Handheld Recorders, another great OEM idea, this thing on phantom sucks the juice like crazy.

So thanks again for the discussion, and yes, better audio just never hurts...

Bob, in Columbia, MO

Mark S from B&H made an earlier comment about the "built-in limiter always being on."  Could you go into a little more detail about that, Mark?  The manual does not say anything about it that I noticed.

In my testing, I turned off the limiter with the toggle switch on the back of the DR-100 MKII, and I expected to have no limiting going on.  However, when I purposedly tried to clip with a hot signal, the recorder seems to automatically limit the level to -6 dB — and it sounds terrible, very overmodulated, even though the level does not hit 0 dB.  And, again, this happens with the limiter turned off with the toggle switch on the back.

So am I understanding correctly, that even if you turn the limiter "off" with this switch, the limiter is still working (and sounding very bad)?  

What if you do not want any limiting in your signal path?  Is that possible?

Or, is it truly impossible to reach a signal level of -5 or -3 or -1 dB?  Does this mean that we need to treat a level of -6 dB as the new 0 dB?  

If that is the case, could Tascam give us a firmware update that would actually disengage the limiter, or make it more subtle?  It seems to work like an ugly brick wall at -6 dB.  (My firmware says "ver. 1.0" on the startup screen.)

Hello -

My remarks were taken from information provided by Tascam in the owner's manual.  Are you able control the cassette deck's output level?  That may provide an easy solution.  If all attempts to remedy are stymied - please e-mail us at [email protected] so we can follow up with you.

Hi Jimbee, 

This is a late response to your comment, but I've been having the same exact issues that you've mentioned. I just got a Tascam Dr mkii 100, and when using a Shure SM 58 mic with it, it seems to hit an automatic wall at -6 DB on Mono mode. It does not do that, however, on Stereo mode. I was wondering if you happened to figure out what was wrong, or what was happening. I'd appreciate any advice or help. To get the best sound, I've been recording on stereo (into one channel) then switching it into mono in post, but it's been quite the hassle (plus monitoring in one ear is rather difficult). Thank you for your help in advance. 

Hi ElleBelle -

Double check that "phantom power" is not enabled.  Set the recording level control function used on the mic inputs. The default value is LMT.  When set to LMT (limiter), the input gain will be adjusted automatically according to the analog input level, so that the recording level will not be distorted even if the input signal is very loud.  When set to AUTO (auto gain control), the gain is automatically adjusted to make the volume as even as possible. The gain increases for low-level input signals, and the gain decreases for high-level input signals. When the input is LINE 1/2, regardless of the TYPE setting, the inputs will always be treated as STEREO.  When the LEVEL CTRL setting is AUTO, the volume will be automatically adjusted, so the INPUT knob is disabled.

Please see page 32 of the OWNER'S GUIDE for more recording tips.

Please contact us via e-mail if you have additional questions:  [email protected]

Meaning I cannot record mono files via line 1 or 2?

Hi Phillip -

Not at all.  When only one mic is connected, it is possible to record the same signal on both left and right channels. (See “Making analog input settings” on page 30.)  When TYPE is set to MONO ,the recording will not be a mono file. Rather, it will be a stereo file with the same signal recorded on both left and right channels.

Very good article.

I have a question regarding the possibility of using the two units along (Tascam DR-100mkII and Sound Devices USBpre): Isn't the Sound Devices powered up by USB only?

 Thank you 

Hello -

Yes  - the Sound Devices USBPre2 is USB powered only.  Using this combination with a laptop would be the best method of maintaining portablity for mobile use.

I see no mention of timecode and how it is handled by the Tascam. Is timecode part of the WAV or MP3 format that is exported with audio?

There is no embedded timecode offered on this recorder. It is a feature found on the higher end pro audio recorders. For example the Tascam HD-P2 . That recorder will have timecode capability.

Is the housing really aluminum?  Somone told me that it was plastic, he owns one and is convinced it is plastic.

Hello -

The case is indeed aluminum.  The lightness of plastic for sure, but the durability of metal.  Please click on Tascam to view their confirming speciication.

Hi  there. I'm considering buying the new DR-100mkII but I would like to know if it's possible to connect analog sources as a Tascam 112mkII Cassette deck to the DR-100 to convert analog sources (tapes) to Mp3 format? if so, I would need RCA out of the cassette deck going to dual XLR? into the Tascam DR-100, right? I know that  tape gives me a line level of -10dbu-and the new Tascam has a switch at the bottom to change the XLR from mic to line but would -10dbu be too low for the line level since I read  that it now takes professional line level +4dbu? or would I be better off using the mini jack line in on the side?


Erick in Toronto

Hello -

The Line 2 IN jack (mini 3.5mm, 1/8") does offer a nominal input level of -10 dbV  -  but the automatic built-in limiter, which is always active, can raise the signal as high as +6 dbV as well. You should be able to make a good digital copy using the Line 2 input.

Excellent! This recorder has a lot to offer to everyone! Thanks!

Actually, the built-in limiter is NOT necessarily always active, but can be turned off with a switch on the rear of the TASCAM DR-100mkii. [See the manual, pg 32.]

This machine is a terrific, inexpensive, pristine-sounding, pro-quality recording unit when paired with a Sound Devices USBPre2 through the digital input.

You've basically got an SD 702 for about half the price and with much greater versatility.

And the USBPre2 can be powered in the field for a long time with a USB battery pack like the XP4001. No need for a laptop.

There is no way the case is aluminum. It's plastic. Hard plastic. The Tascam spec sheet says it's aluminum, but there is no way that's correct. Total typo on their part.

Thanks so much for all of the info.  There's not a lot out there about this new recorder!

Can you tell me how the external mic preamps in the DR-100 MKII compare to the Roland R-26, and also to the Marantz PMD-661?  I know they are all different price points, but I'm willing to pay more for the Roland, or even the Marantz if they are significantly better.  If this recorder is just as good, or just ever so slightly noisier, then choosing this one would be a no brainer. Thanks!

Hello -

I think this is a case of  "you get what you pay for".  All three recorders you have selected are excellent machines that are "best in class" devices at their respective price points. As far as their mic preamps are concerned, I would group the Tascam and Roland as similar, with Marantz being the clear winner.  The Roland is a good choice over the Tascam if you desire 6 track capability.  For a more premium price, Marantz is offering the best combination of features, functionality and robust build and design.

Thanks so much!  That's what I suspected, but I just haven't been able to find any comparisons or confirmation.  The better preamps are my priority, as is the rugged design, so I will definitely shell out the extra cash for the Marantz.  Desicion made! Whew! Thanks again!
