1) The DXA-5Da operates on one 9 volt battery. We recommend that
you use either an alkaline or lithium type battery for the longest
2) The adapter only requires battery power for operating the LCD
panel, AGC disable feature and headphone amplifier. No power is
required to pass the audio signal.
3) To install the battery simply open the cover by pushing on the
end of the cover to unclip it. Insert the battery with the "+"
positive terminal lined up with the "+" indicator on the battery
compartment. Replace the battery cover.
Mounting the Adapter on the Camera
1) Line up the mounting bolt on top of the adapter to the tripod
hole on the underside of the camera. Carefully turn the top
mounting knob to the right to screw the adapter squarely into the
2) Use one of the supplied output cables and connect one end to the
MIC OUT of the adapter and the other end to the MIC IN on the
3) 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 mixing board.
3) Set the G1/G2 switch to G1. You may have to change this to the
G2 setting if you encounter any ground loop noise when attached to
a mixing board. You will need to do a test recording and playback
to determine the best position for your setup.
4) Set the M/S switch to M for mono when using one microphone. Set
the unused channel trim control fully clockwise so that it does not
interfere with the working channel. When using two microphones, you
should normally set the switch to S for stereo to keep each channel
5) Set the AGC DSBL switch to the left so that it is
6) Set the LEFT and RIGHT trim controls fully clockwise to 10.
7) 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.
8) Turn the adapter PWR switch to ON.
After following the above Initial Setup, you should be ready to
1) The level meters on the adapter monitor the signal strength from
your sound source. It is normal if you do not see the meters move.
They will only register when using sensitive type microphones or
when you are attached to a mixer or wireless microphone.
2) Keep the trim controls at the maximum setting for unity gain.
Only adjust the trim controls if the input signals exceed -36 dBu
on the level meters. If you have a mixer or some other form of
amplified signal connected to the adapter, adjust the trim controls
to give you a peak reading of -36 dBu. This is the "weet spot" for
attaining the highest signal to noise ratio from the camera
3) Adjust the VOLUME control for the headphones to a comfortable
4) Do a test recording and play back the audio to determine if the
captured audio is acceptable. Note you will not be able to monitor
the playback audio from the adapter.
5) 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. The tone is recorded by the
camera but can be easily filtered out if necessary. You can still
use the left channel for recording normal audio at the same time as
the AGC DSBL feature is active.
When this feature is active, you will see 2 or 3 bars indicate on
the level meter for the left channel (when the M/S switch is set to
S for stereo) which verifies that the tone is being sent to the
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 signal.
Again, it is important that you do a test recording and play back
the audio to see if it is acceptable.
The AGC DSBL feature will lower the gain on the camera, which will
require a sensitive microphone for best results.
