QUICK START

Look around to make sure no one catches you reading this. You’re aware this is the manual aren’t you? Wow! Most
people only get about this far in a manual, but there are a few important things you should know about the AVA 22d. So
please keep reading. These few points are summarized in this Cliff Note version of the manual.

The first time you power the AVA 22d it is in BYPASS, and functions like an expensive wire. This is useful for initial
troubleshooting and allows for convenient verification of signal flow. Punching the BYPASS buttons and extinguishing
their LEDs will activate the Delays.

ADJUSTING SENSITIVITY—First apply a signal with nominal input level and adjust the SENSITIVITY controls so
the red CLIP LEDs just light, then back off so the LEDs do not turn on, even with high signal peaks.

SETTING DELAY—Now that the input signal is calibrated, select LINK mode (LINK LED on) for stereo operation,
or turn off LINK mode for dual mono operation. Adjust the up/down buttons until the LED display shows the desired
Delay.

STORING DELAY—Press the STORE button (the STORE LED turns off). This stores the current Delay values into
each Channel’s current Memory (A or B). The current Memory is indicated by the lit MEMORY LED for each Channel.
Both Channel’s current Delay values are stored with each press of the STORE button. The broadcast Mode (NTSC or PAL/
SECAM) is also stored with the Delay value.

RECALLING DELAY—To recall a stored Memory, press RECALL. Each press of this button alternately recalls
stored Memories (A then B then A…).

Never connect anything except an approved Rane power supply to the thing that looks like a telephone jack on the
rear of the AVA 22d. This is an AC input and requires special attention if you do not have a power supply exactly like the

one originally packed with your unit. See the full explanation of the power supply requirements elsewhere in this manual.

FRONT PANEL DESCRIPTION

 SIGNAL indicators: These green LEDs illuminate approximately 42 dB before actual clipping.

 SENSITIVITY controls: These rotary controls vary incoming signal levels to the A to D converter. The output signal is

also adjusted so the AVA 22d always passes signal with unity gain into 600 ohm loads. (See operating instructions.)

 CLIP indicators: These red LED indicators illuminate 4 dB before clipping at the A to D converter input.

 STORE indicator: This flashing LED indicator alerts the user that the current configuration of the AVA 22d is different

from the stored configuration. The STORE LED is off when the current configuration matches the stored configuration.

 STORE button: This pushbutton stores both Channels’ current Delay configurations into the given Channels’ current

Memory (A or B). The current Memory for each Channel is indicated by the lit MEMORY LED for that Channel.

 LINK indicator: This green LED lights when the unit is in LINK mode. LINK mode allows stereo operation.

 LINK button: This pushbutton toggles between LINK mode (stereo operation) and DUAL MONO operation. (See Operat-

ing Instructions.)

 BYPASS buttons and indicator: These momentary push buttons toggle each Channel’s hard-wired Bypass. If an LED is

on, the given Channel is Bypassed and functions like a wire. If it is off the given Channel is active.

 MEMORY indicator: These LEDs indicate the most recently recalled Memory, A or B, for the given Channel. They also

indicate the Memory that is written to when the STORE button is pressed. The MEMORY LED flashes when the current
Delay value for that Channel is different than the stored value for that Channel.

 RECALL buttons: Pressing one of these pushbuttons alternately Recalls stored Memories A and B for the given Channel.

 MODE buttons and indicator: These buttons toggle the broadcast mode for the given Channel, NTSC or PAL/SECAM.

Each Channel contains LEDs indicating the current broadcast Mode.

 FRAMES displays: These 2-digit displays indicate the current Delay value for the given Channel. On power up this display

also shows the currently installed software revision level.

 UP/DOWN buttons: Pressing these buttons increases/decreases the amount of Delay in the given Channel.
