DXA-SLR solves Canon 7D audio problem

I love DSLR cameras with video recording capabilities, and so I was happy when Canon finally released the EOS 7D with its video recording capability. Surprisingly, when I purchased my Canon 7D and did a few test video recordings, I was disappointed with the quality of sound in the video. I began to explore many opportunities by adding on condenser mics such as Rode VideoMic which I usually use together with BeachTech DXA-6A for my Sony VX2100. Before then, I had read many reviews on BeachTech DXA-SLR audio adaptor which has +48v phantom power for condenser mics that need to boost up their power. For those who don't know yet, one of the major problems with Canon 7D audio feature is the Auto Gain Control (AGC) which makes the camera pick up unnecessary "hiss" noise during recording. DXA-SLR has a little switch and when used, it easily overcomes the AGC problem. To my amazement, when I switched the DXA-SLR AGC disable to the "on" position, and plugged in my Rode VideMic the recorded sound was splendid. The sound was even more powerful than what I usually get from my Sony VX2100 (3CCD MiniDV video camera). There is also a headset input that makes you listen in to the recording to give you an idea what you are doing. There is yet another good feature of this little box which is very helpful, that is, there are gain switches found underneath it. These switches have +15db for either of the two channels and you can set it "high" or "low" depending on how you want the quality of the recording to be. Honestly, I can't say how much I love this little gizmo; before I purchased it, I had put all my hopes on the day "Magic Lantern" would come out with 7D version of their audio manipulative firmware that has the capability to disable the troublesome AGC. But let's thank God beachtech DXA-SLR has saved the situation for Canon 7D owners. So far, there is one thing I don't like about DXA-SLR. That is, there is no audio meter on the box like the one found on DXA-5DA that tells you how high or low your recording is. The way DXA-SLR looks like, you always have to rely on your headset to determine the loudness of your recording. Sometimes this can be frustrating when you are in a small room or hall. But on the whole, I have not wasted my money. If you are a canon 7D owner, please give it a try, and you won't regret for buying DXA-SLR.

For run n gun ENG work; especially one-man-banding it with an HD-DSLR, audio is a huge sticking point. The beachtek adapter does a decent job at getting professional audio into the camera, with the lack of any other compact, non-field-mixer options (there's only so much we can carry by ourselves!) it's probably the best option out there right now.
That's not to say it's perfect. The pre-amps are noisy, ground hums come and go, clicks show up, the LED metering lights (another draw-back; only one light to indicate signal and no return monitoring from the camera) create a noise of their own. All of this can be filtered out quite easily in post, but isn't the point of ENG gear to keep post to a minimum?
After my first shoot I contemplated returning the box, but it's grown on me, especially in the face of no other viable option for the one-man-band ENG crew.
If at all possible get a dedicated audio engineer with a boom pole and a field mixer; if not, the Beachtek box will do.

I have only usd this device a little so can not attest to it in the long run, but it seems to be a perfect solution for me! I am a new pro-amature looking to use my 7D to make some professional looking interview and blog videos. I do not want to have to synch audio so i know i am limiting myself to not the best quality, That being said, this was the perfect option for me. I can record right to my 7D without haveing to Synch audio, i can plug in a lapel mic or a shot gun mic or both, and monitor audio with my headphones and adjust levels. Seems to solve me needs! one unique word of warning, being new to this, i was trying to not buy too much new equipment. I used my Dre Beat Solo headphones, fguring they were good headphones to monitor. They gave me some real weird feedback, Checked all of my other variables and it all came down to those headphones. So make sure you use monitor headphnes or even earbuds worked ok, something about those Beats didnt work well.

Don't waste your time with a Zoom if you don't have to. This is the best audio you can get without getting an field audio person. If you are running with mics,you can run them right to the camera, with no sync later. The sound is perfect. This is the best thing I could have done for my DSLR.

This unit delivers as advertised. I bought it for use with a Panasonic HMC40 instead of the Panasonic XLR accessory because I also needed a unit to use on my Canon 60D. Performance & results on both platforms were the same…excellent. Only feature missing is a multi-led level indicator.

Comments about Beachtek DXA-SLR Active Audio Adapter:
This little box saved me hours of post-production. If you are planning to make a documentary film, you MUST record audio into the camera even if it is a DSLR. I was the sound recordist for this project, but also I made the re-recording mix, so I bought this piece of hardware one month before the shooting schedule to make some tests. Other options was to use a TC generator or use Plural Eyes plug-in to sync all the audio. Fortunately there was no need for this. We used Canon 60d, 5d and Lumix GH-1. I have not tried it with AGC.

We use this with a Canon EOS 60D. Sound is incredibly clear, the immense amount of fuzz that once existed in audio recorded straight to the camera is virtually gone! While it definitely adds a bit of heft to the camera it's nothing that makes it unwieldy. Everything is very accessible and nothing is blocked when attached to the camera.

This is an ingenious device. It allows you to put two mikes on a camera that normally should only take one. Also, you can override the automatic controls and set manual levels. It's a little bulky, but it that's the price you pay for this functionality.

We started using the DXA-SLR adapter with our DSLR and it's amazing. We are now able to record live audio during our events and be able to have synced audio in post. This is a great product. Only thing is that it's a bit pricy. Other than that, it's perfect.

This is a great kit, a bit expensive though... and takes a bit of practice to get the sound right. I paired this with the DXA-SLR Active Audio Adapter by BeachTek and EW112-p G3 Camera Mount Wireless Microphone System with ME2 Lavalier Mic (A / 516 - 558 MHz) by Sennheiser Electronic... I do interviews on my Nikon d7000... Still learning but really happy with this purchase.

I have been using a BeachTek audio interface box on my Sony VX2100 for years with no problems so when I got a Canon 60D I went to the BeachTek site and found the DXA-SLR. Easy to setup and use. Would be nice to have a external power supply option for long shoots.

Comments about Beachtek DXA-SLR Active Audio Adapter:
The DXA-SLR allows direct input of two audio channels for DSLR Cameras. I use it on my Canon 5D Mark II (for which this Beach-Tek model was designed) and 7D.
Using the manual audio setting in my 5D, it is fairly simple to set general levels for my mics while using it with the 7D requires dumping and analyzing a clip in the computer. This is very important, because the BeachTek has no live metering capabilities, making it hard to tell when your signal peaks or becomes too soft, other than your own ear.
The audio quality is good after getting your levels set correctly, but the cameras themselves only allow 16 bit audio depth, which is enough, but as bigger gets smaller I find that 24 bit is becoming more the standard.
For the price, I think these products are wonderful. But in general, I find that the BeachTek is a problem solver, not the solution.

Comments about Beachtek DXA-SLR Active Audio Adapter:
We use the adapter anytime we need to record audio other than with the shot gun mic on the NEX camera. The flexibility of line or mic input and Phantom power with the XLR connectors makes the system just like our broadcast DBeta and XDCAM systems so all of our audio accessories are available to the NEX.
The AGC defeat is great.

I use this with a Canon 7D. It works well. A little bit difficult to get used to but works like a charm. I'm really impressed with the DXA-SLR and it's the only way to get good sound from your 7D. I like that it is light weight and easy to use.

I use this with my canon t3i. it works well. i havent gotten much of a chance to get to know the product but so far it works great. some agc problems, im not sure if its because of my microphone or the product. i think its my mic. also im not really sure how to use the 3.5 mm jack yet. that might have been confusing for some.

Comments about Beachtek DXA-SLR Active Audio Adapter:
I really didn't want to use an external recorder, so I got this. I wish someone had smacked me before I bought it. The amount of work to clean up the audio this produces takes far longer than the amount of time it takes to sync external tracks. You can't preview the actual audio going into the camera.
The fact of the matter is that these DSLR's weren't built for recording audio. Certainly not at the quality anyone upgrading from a cheap camcorder would expect. Just get the Zoom H4n. Trust me, it is enormously more useful, better quality and even cheaper.

Comments about Beachtek DXA-SLR Active Audio Adapter:
Provides far superior audio to built in camera mic. Sturdy XLR inputs. Headphone jack a plus. Ability to use 2 mics and adjust levels individually. The disable auto gain feature works superbly. Puts less stress on 3.5mm audio input jack than using a cable directly to the camera. Recommended for serious audio on a DSLR. Price is a bit steep. Access to high/low gain switch is on bottom, so you need to detach from camera to change, which is a minor inconvenience.
