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 22. So
please keep reading. These few points are summarized in this Cliff Note version of the manual.
The first time you power the AVA 22 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 22. 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.
Note: To avoid audible anomalies, the AVA 22 bypasses the audio signal any time the Delay value is changed.
600 ohm users see page Manual-4.

FRONT PANEL DESCRIPTION
햲 SIGNAL indicators: These green LEDs illuminate approximately 42 dB before actual clipping.
햳 SENSITIVITY controls: These rotary controls vary incoming signal levels to the A to D converter. The output signal is
also adjusted so the AVA 22 always passes signal with unity gain into 600 ohm loads. (See operating instructions.)
햴 CLIP indicators: These red LED indicators illuminate 5 dB before clipping at the A to D converter input.
햵 STORE indicator: This flashing LED indicator alerts the user that the current configuration of the AVA 22 is different
from the stored configuration. The STORE LED is off when the current configuration matches the stored configuration.
햶 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.
햷 LINK indicator: This green LED lights when the unit is in LINK mode. LINK mode allows stereo operation.
햸 LINK button: This pushbutton toggles between LINK mode (stereo operation) and DUAL MONO operation. (See Operat-
ing Instructions.)
햹 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.
햺 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.
햻 RECALL buttons: Pressing one of these pushbuttons alternately Recalls stored Memories A and B for the given Channel.
햽 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.
햾 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.
햿 UP/DOWN buttons: Pressing these buttons increases/decreases the amount of Delay in the given Channel.

REAR PANEL DESCRIPTION
햲 REMOTE BYPASS/RECALL terminals: Wiring external configuration switches to these terminals allows remote stereo
bypassing or stereo memory recalling of the two nonvolatile memories. These terminals use CMOS (+5 volt) logic levels
and sink only 3mA (max) each.
햳FRONT PANEL LOCKOUT switch: Enables the Front Panel Lockout mode. In this mode all front panel controls, with
the exception of the RECALL buttons, are disabled. Press a RECALL button while in LOCKOUT to temporarily display,
but not Recall, the value of the other stored Memory for the given Channel. (See Operating Instructions for optional Bypass
Lockout mode.)
햴 XLR INPUT/OUTPUTS:. Nothing new here, balanced Ins and Outs. If you desire unbalanced characteristics (like hum),
you can also wire the AVA 22 in an unbalanced configuration. See RaneNote 110, “Sound System Interconnection” located
elsewhere in this manual.
햵POWER connector: No, this is not where commissioner Gordon plugs in his Bat-phone, in fact it is not a telephone jack at
all. The AVA 22 uses an 18 volt AC center-tapped transformer only. Use only a model RS 1, RAP 10 or other remote AC
power supply approved by Rane. The AVA 22 is supplied with a remote power supply suitable for connection to this jack.
Consult the factory for replacement or substitution.
햶 Chassis ground point: A #6-32 screw and toothed washer is provided for chassis ground. Since the AVA 22 does not get
chassis ground through the AC cord, this point is provided if your system does not have another earth ground such as the
rack rails.
IMPORTANT NOTES
FCC & VDE NOTICE
This equipment has been tested and found to comply
with the limits for a Class A digital device, pursuant to Part
15 of the FCC Rules, and similar requirements found in
European specifications EMCD 89/336/EEC. These limits
are designed to provide reasonable protection against
harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses,
and can radiate radio frequency energy, and if not installed
and used in accordance with the instruction manual, may
cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to
cause harmful interference in which case the user will be
required to correct the interference at their own expense.
CHASSIS GROUNDING
If your system exhibits excessive hum or buzzing, there is
an incompatibility in the grounding configuration between
units. Here are some things to try:
1. Try combinations of lifting grounds on units supplied
with ground lift switches (or links).
2. Verify all chassis are tied to a good earth ground.
3. Units with outboard power supplies do NOT ground the
chassis through the line cord. Make sure these units are
solidly grounded by tying the Chassis Ground Point to known
earth ground. Use a star washer to guarantee proper contact.
(See the RaneNote “Sound System Interconnection” for
more.)
