        Comments about Sound Devices MM-1 Single Channel Portable Microphone Preamp:

        This preamp rocks. It was the missing piece to my audio recording puzzle. I use this with my Tascam DR-100 and it works perfect. Very easy to use and does it's job well. I run the line in to the DR-100 and it brings the audio up beautifully. I find the sweet spot to be 0-46 db. The batteries last forever. I just wrapped an indie short and didn't have to replace one set of AA batteries! And like others have said, this thing is a beast. It's super heavy duty and VERY solid. Well worth the price.

          Top-notch mic preamp. I use this with my Rode NTG-3 and it sounds great. Way better than any preamp that's going to be built in to an external recorder. If you want crystal clear audio that's EXTREMELY difficult to peak, this is for you.

            Comments about Sound Devices MM-1 Single Channel Portable Microphone Preamp:

            I bought this to power my Audix Hypercardiod mic. I run it into a Tascam DR-40 and the system works great! The preamps on the DR-40 produce quite a bit of noise if I use it to power my mics. So the MM-1 supplies the phantom power and I get virtually no noise. I just send the Tascam a line level signal and it's perfect! The limiter works great and it's VERY hard to clip.

            The Sound Devices MM-1 is built like a tank. One day after a long day of filming I dropped the MM-1 from about 5 feet straight onto the pavement. My heart stopped as I slowly saw it fall. But alas, there was only a small paint chip and the thing is still working perfectly.

            It's a bit heavy, but when considering it's durability it makes sense. Tanks aren't supposed to be light!

            Highly recommend it!

                  First video shoot out of the box was crazy good in the audio department. Tons of preamp signal coupled with my Sennheiser shotgun mic. And the audio sounded fantastic in post! Now if I only had enough cash to get their model with digital audio recording. Someday . . . .

                    Comments about Sound Devices MM-1 Single Channel Portable Microphone Preamp:

                    I bought the MM-1 to feed the Blackmagic Cinema Camera. This seems to be a no frills unit which keeps the controls and displays to the minimum.Then, you discover the HUGE FRILL included, a combination input/output limiter which will likely pay for itself on every shoot. The limiter is exceptionally smooth and controls transient bursts with aplomb. It drives headphones to deafening levels, so, use caution. Audio quality is typical of Soumd Devices, about as good as it gets, across the board. Powering shotguns (make sure to select 48 volts, not 12!) and other mics is no issue, working perfectly. The 12 volt option allows use of certain mics requiring it, and this option can potentially damage 48 volt mics, so care should be taken. The unit is built like a tank, and is powered by just a couple AA batteries, available everywhere.

                      This is a rock solid mic preamp made to produce professional results. After tons of research, all the pro's point to SD. The mm-1's price tag allowed me to purchase without breaking the bank. Hooked it up and worked perfectly right out of the box. I am using with a Zoom H4n and results are great. Keep in mind, if you plan to use it will an H4n, you'll need an attenuator because the H4n cant handle the mm-1's output.

                        I was not getting much reach with my rode ntg-3 and my beachtek dxa-8 preamp. The Sound Devices MM-1 solved that problem. I am now getting decent levels at 14 feet away at medium gain with no noise. So, if you are a one man crew and are using on camera mics (I know, not ideal) you need a sensitive preamp like the MM-1. Same electronics as the mixpre (maybe even a slightly hotter signal on the MM-1).Of course, it is only one input/output so if you need stereo, you'll need the next step up to the mixpre. The MP-1 is also good and cheaper, but has no external power option or headphone monitoring. They all have pretty much the same footprint.

                          Gives me all the gain I need for independent film/wedding making and is a solid piece of equipment that looks and feels heavy duty.
                          Liked that the brackets on top protects the knobs in case it falls.

                          Goes through batteries pretty quick depending on your settings. Consider the power supply if your environment has an outlet.

                            This thing is just fabulous! I use it with my Tascam DR-40, my Rode NTG-3 and make these puppies talk with Mogami Gold series xlr's, short ones. The size of it is perfect for those hard to reach shoots, and the gain and clarity are worth every penny. This device is easy to use, seems very durable, and if you pay attention to the power button a bit, the batteries last a long time. I highly recommend this to anyone and would buy this item again for sure. I consider this the missing link to my audio rig. Now things are finally starting to sound real..........ya know?

                              I purchased to use with a dynamic microphone. Im using to record on a TASCAM DR-100mkii. The MM-1 preamps are 100% better then the TASCAMS. In addition it is super powerful.

                                  Using this for airshow work, this Sound Devices MM-1 is light, long-lasting power wise if turned off when not in actual use. The gain is so clean it brought in sounds from far across the airfield. The Limiters work outstandingly well when a flight of F-18's took off nearby and nothing was clipped. Using Hosa Shielded XLR to 1/4 TRS into the Tascam DR-40 to bypass it's lame (for my use) Preamps produced an outstanding recording.

                                    I use this for my boom guy to monitor and send boom signal to my cart. It sound great and adds gain when I need a little extra. Nothing bad to say about it. For the price it's everything I expected and a little more. It also makes my lower end boom mics sound a bit better.

                                      I needed a parab for a Ski Jump documentary I am DP'ing and was having a hard time finding a rental, so I decided to bite the bullet and purhcase one. By far, the BEST purchasing decision I have made recently! I also purchased the MM-1 Single Channel Portable Microphone Preamp for this kit, which worked perfectly as well. I was able to capture audio from the skier pushing off the pipe, all the way to the bottom of the out-run.

                                        When I plugged a shotgun mic into my portable audio recordeder I got really terrible levels. I use this preamp to boost the gain. Now I can make my levels as high as I want. Works really well was the missing link for my audio setup.

                                        Great in all respects except for lack of mounting options.

                                        I use this mixer (pre-amp) in conjunction with my digital audio recorder and shotgun mic. This pre-amp has LOTS of gain and it's virtually noise-free. My digital audio recorder is pretty cheap so it's pre-amps have noise. So I keep the gain levels low on my audio recorder and use the MM-1 to increase the gain to proper recording levels. Works great!

                                        My shotgun mic has a low dB output so the MM-1 is essential for increasing the gain without increasing the noise. I haven't used the limiter or low-end roll-off options yet but they look good. I also appreciate the sturdy construction of the unit. It feels very solid and dependable.

                                        My only complaint is that there's no 1/4-20 screw hole for mounting options. There's a belt clip and some small handles for attaching a neck strap. But I want to attach it to my video camera, not to my person. So I might gaff tape it to a cheese plate just for the 1/4-20 mounts. Not ideal.

                                            This thing sounds good. Replaced the built in pre's in my Korg MR-1000 and sounds significantly better. More open, transparent sound with less noise at higher gain levels. Definitely a worthwhile investment.

                                                I use this mixer to monitor round table discussions through a boundary microphone.

                                                It is very well made, quite small.

                                                My only quibble is the small switches are too flush and are partially blocked by the handles making them difficult to operate.
