1) The DXA-SLR operates on one 9 volt battery. We recommend that
you use either an alkaline or lithium type battery for the longest
2) To install the battery simply unlatch the drawer by pushing in
and up on the front drawer front to release it and slide out.
Insert the battery with the "+" positive terminal lined up with the
"+" indicator on the battery compartment. Slide the battery drawer
closed until it clicks into place.
Mounting and Connecting the Adapter to the
1) Line up the mounting bolt on top of the adapter to the tripod
hole on the underside of the camera. Carefully turn the adapter
mounting knob on the front panel to the right to screw the adapter
squarely into the camera. Snug the adapter to the camera, but do
not over tighten.
2) Use one of the supplied output cables and connect one end to the
OUT of the adapter and the other end to the MIC on the camera.
3) To monitor audio from the camera during playback, connect the
red and white RCA plugs on the supplied AV cable, or the AV cable
that came with the camera to the corresponding red and white
MONITOR IN jacks on the adapter. Attach the other end to the AV
output of the camera.
4) You can also mount the adapter to any standard tripod.
1) Connect your microphones or other audio gear to the adapter via
the XLR inputs or AUX mini-plug input.
2) Set the LIN/MIC switch to either MIC when connecting microphones
or most wireless receivers, or to LIN when taking a line level feed
from a mixer or sound board.
3) Set the MONITOR Switch to XLR to monitor the audio from the
microphones during recording.
4) Set the GAIN switch on the bottom of the adapter to HI. This is
the normal setting for most microphones. If you are using very
sensitive condenser type microphones, or recording very loud
sounds, you may have to set the GAIN switch to LO to prevent
5) Set the GROUND switch on the bottom of the adapter to G2. You
may have to change this to the G1 setting for some cameras or
camcorders if you detect any unusual noise. You will need to do a
test recording and playback to determine the best position for your
6) Set the M/S switch to M for mono when using one microphone. Set
the unused channel level control fully counterclockwise to 0 to
disable it to prevent noise. When using two microphones, you should
normally set the switch to S for stereo to keep each channel
7) Set the AGC DSBL switch to the left so that it is
8) Set the LEFT and RIGHT level controls fully counter-clockwise to
9) Plug your headphones into the PHONES jack to monitor the audio.
Be sure that the VOLUME control is set low to avoid excessively
loud audio from damaging your hearing.
10) Turn the adapter PWR switch ON. The power LED should light
green indicating good battery voltage.
11) Activate the 48V phantom power switch for only those
microphones that require 48 volt phantom power to operate. Do not
activate phantom power for dynamic microphones, condenser
microphones that do not operate on phantom power, wireless
receivers, mixing boards or any unbalanced device as it may cause
damage to both the adapter and connecting device.
After following the above Initial Setup, you should be ready to
1) Use the signal indicators on the adapter to set the proper
output levels for recording. Increase the level controls for each
channel that is being used so that the signal level LED flickers
green. If the indicator turns red, decrease the level so that it
flickers green again.
2) Adjust the VOLUME control for the headphones to a comfortable
3) Do a test recording and play back the audio from the camera to
determine if the captured audio is acceptable. Set the MONITOR
switch to RCA to hear the playback audio from the camera.
4) The Auto Gain Control (AGC) in the camera will vary the amount
of gain depending upon the input signal level. During quiet
moments, the AGC will increase the gain, which will also increase
the amount of hiss from the camera preamplifiers. See "Using the
AGC DSBL Feature" below to reduce this problem.
Using the AGC DSBL Feature
This switch is a means to disable the wild swings of the Auto Gain
Control in the camera. It activates an inaudible tone of 20 kHz to
the left channel (when set to STEREO operation) that prevents the
Auto Gain Control from increasing the gain to its maximum level.
This reduces the hiss that normally occurs when the camera is
recording audio during quiet moments. This inaudible tone is
recorded by the camera but can be easily filtered out if
You can still use the left channel for recording normal audio at
the same time that the AGC DSBL feature is active. You may also
want to record audio only on the right channel and leave the left
channel unused for the AGC control signal if this tone presents a
problem down the line. In this case, you should set the M/S switch
to S for stereo to keep the AGC signal separated from the recorded
Again, it is important that you do a test recording and play back
the audio to see if it is acceptable.
