OPERATING INSTRUCTIONS

Once you've properly connected the AVA 22d to the

system, turn on the power. When the AVA 22d is first
powered, the revision level of the software is displayed.

THE BASICS

The AVA 22d is a two Channel device. Each Channel has

a current Delay value that is always active/heard. You can
only edit the current Delay values. Additionally each Channel
has two nonvolatile Memories, A and B. The current Delay
values can be stored in one of these two Memories.

SENSITIVITY SETUP

The first step is to apply signal and adjust the Sensitivity

controls. If you know the nominal level, adjust the control
indicator to that level. Otherwise, set the Sensitivity control
so high signal peaks just illuminate the CLIP LED, then back
off a little.

ADJUSTING CURRENT DELAY VALUE

One Channel at a time: With the LINK LED off, press

the up/down buttons for the Channel you want to adjust until
the desired Delay value is reached. That’s it!

Both Channels simultaneously: With the LINK LED on,

changing either Delay value changes the other Channel’s
Delay value by the same relative amount. (The Delay values
are linked.) BYPASS, RECALL and broadcast MODE are
also linked together in LINK mode.

When entering LINK mode, Channel 2’s current Bypass

and Memory settings are stored and replaced with Channel
1’s current Bypass and Memory settings. This may cause a
Memory Recall to occur in Channel 2. This Recall may also
include a change in broadcast Mode if the Recalled Memory’s
Mode is different. Channel 2’s stored Delay value is not
changed to match Channel 1’s Delay value. (Channel 2’s
stored delays remain unchanged.) When leaving LINK mode,
Channel 2’s Bypass and Memory settings are restored to their
dual mono settings. Again a Memory Recall may occur, thus
restoring the stored Channel 2 value.

STORING DELAYS

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 for each Channel is
indicated by the lit MEMORY LED for that Channel. Both
Channels’ current Delay values and broadcast Modes are
stored with each press of the STORE button.

RECALLING DELAYS

Press the RECALL button. Each press of this button

alternately Recalls stored Memories (A then B then A…) for
the given Channel. Pressing RECALL while editing Delay
values writes over the changes you’ve made if you have not
stored them.

REMOTE RECALLS

The rear REMOTE RECALL terminals are functionally

equivalent to the front panel RECALL and BYPASS buttons
while in LINK mode. When the switch closes, both Channels
are Bypassed, or, for the other switch, both Memory B’s are
recalled. Both Channels are activated (or both Memory A’s
are recalled) by opening the switch. These terminals can not
be locked out.

An internal jumper is provided to redefine the REMOTE

RECALL function. (See W3 in the board layout diagram.)
Moving this jumper from its default position redefines the
Stereo Bypass Remote terminal as a Channel 2 Memory
Recall terminal. The other terminal (defaulted as Stereo
Memory Recall) becomes a Channel 1 Memory Recall
terminal. This is convenient for mono video houses, allowing
one equipment room to use Channel 1 and another room to
use Channel 2 independently.

INTERNAL BYPASS JUMPER SETTING

Internal jumpers enable or disable the BYPASS buttons

while in Front Panel Lockout mode. The default setting of
these jumpers disables the BYPASS buttons in Front Panel
Lockout mode. (See W1 and W2 in the board layout dia-
gram.)

HOLE PLUGS

Once your system is properly configured, the Sensitivity

knobs can be removed and the unit secured by replacing the
knobs with the provided hole plugs.
