DCR822
1. Install fresh batteries or connect an external power
source to the DCR822 and attach the antennas.
Power on the unit.
2. Unless frequency settings have been previously
assigned, use SmartTune (p. 13) to select clear
frequencies at your location.
3. Connect the audio cable to the Receiver Audio Out
XLR jack.
4. Set the Power ON/OFF switch to ON and verify
that the LCD panel activates.
5. Adjust the transmitter gain.
THIS IS PERHAPS THE MOST IMPORTANT
STEP IN THE SET UP PROCEDURE. Refer to
your transmitter manual's Operating Instructions
section for details on how to adjust the transmitter
gain. In general, adjust the transmitter gain so that
the voice peaks will cause the audio modulation
indicators on the receiver and transmitter to show
full modulation on the loudest peak audio levels.
Normal levels should cause the DCR822's audio
level icon to fluctuate fully. This will result in the
best possible signal to noise ratio for the system.
Important:
• Adjust the transmitter gain before you adjust the
receiver output level.
• When the transmitter if fully modulated, its limiter
will prevent any further increases in level.
• The receiver output circuitry is set to run at full out-
put, and the level control is simply an attenuator.
There is no difference in signal to noise ratio across
the entire adjustment range of the receiver output
level. The transmitter input gain is the critical ad-
justment that will affect the signal to noise ratio.
• Adjust the Audio Output type (analog or AES3
digital) according to the type of input on your
equipment. Use the LEVEL menu and adjust the
level with the UP and DOWN buttons.
The input levels of different cameras, mixer/record-
ers, and PA equipment vary, which may require
that you adjust the AUDIO OUT to an intermedi-
ate position. Try different settings and listen to the
results. If the output of the receiver is too high, you
may hear distortion or a loss of the natural dynam-
ics of the audio signal. If the output is too low, you
may hear steady noise (hiss) along with the audio.
The DCR822 audio output is designed to drive any
audio input device from microphone level to +7dBu
line level. If using AES3, the audio cannot be ad-
justed.
Note: The test tone output is especially useful
for an exact level match. With the test tone
running, adjust for the maximum desired peak
level using the metering on the connected
device.

Locking and Unlocking the
DCR822 Front Panel Controls
The front panel controls can be "LOCKED" to prevent
accidental changes being made during operation and
handling.
To LOCK or UNLOCK the DCR822, choose MENU/SEL,
then SETTINGS. Use the arrow buttons to toggle front
panel controls. LOCK/UNLOCK, then choose MENU/
SEL to save the setting.
Note: The unit cannot be powered off if
LOCKED. Unlock first to power off.
