The DXA-SLR gives you everything you need to connect professional audio gear to your camera to capture superb sound. The DXA-SLR is very easy to set up and use. The Good/Peak signal indicators show the ideal input levels at a glance while the headphone output lets you monitor what you are recording. The enhanced AGC Disable feature works even better at controlling the wild swings of the Auto Gain Control that plague most cameras. This dramatically reduce the noise during quiet moments of recording allowing you to record two channels of clean audio. You can also monitor the playback audio from the camera. Fits neatly under any camera and can also be mounted to a tripod. Operates on one 9 volt battery.
It Features :
1) Sturdy die-cast aluminum chassis
2) Camera mounting bolt
3) Record/Playback monitor
4) AGC Disable feature
5) Headphone jack
6) Headphone volume control
7) MONO / STEREO output switch
8) LINE / MIC input switches
9) Ultra-slick trim controls
10) Phantom power switches
11) Good/Peak level indicators
12) Two balanced XLR inputs
13) Auxiliary mini-jack input – ideal for wireless mics
14) Output mini-jack to camcorder
15) RCA inputs for playback monitoring
16) Low noise preamplifiers with HI/LO gain settings
Getting the Best Audio Performance - Update
The most common question will be “How do I set the controls on the camera and adapter to give me the best audio?” Because the biggest problem with these DLSR cameras are the poor quality preamplifiers they have, we need to address this issue to reduce the amount of hiss they produce. It is quite simple - the higher the gain, the higher the hiss. Therefore, you want to disable the AGC in the camera and set the gain via the Quick Control Wheel to less than 50% of the maximum for the best signal to noise ratio. After testing we found that a setting of about 25% was the ideal for the cleanest audio and the least amount of hiss. This also calibrated the camera meters with the level indicators on the adapter. Since the meters are not visible on the camera during recording, you can rely on the level indicators on the DXA-5Da or DXA-SLR adapter. Simply use the controls on the adapter to set the proper recording level.
You will need a relatively hot signal to feed into the camera to take advantage of the low gain setting. If you are using the passive DXA-5Da you should be using wireless mics or sensitive condenser microphones that do not require any additional amplification. For most other microphones, our DXA-SLR will be ideal as it has built-in low noise preamplifiers to replace the noisy gain in the camera.
As I mentioned previously, it may sound counterproductive, but for some circumstances it may still make sense to use the AGC of the camera and activate the AGC Disable feature on the adapter to get the best of both worlds. This way you can take advantage of the AGC to reduce the possibility of clipping and distortion while the AGC Disable feature avoids the hiss that normally occurs during quiet moments of recording - ideal for run and gun style shooting.
