TASCAM AV-452
Installation & Support Guide
6 – Customization and settings
The customization and settings of the AV-452 are
made using a set of six DIP switches.
These switches are as follows:
These are explained here:
LEARN IR (switch 1)
This function allows the AV-452 to learn the IR codes
for direct control of a monitor, video projector, etc.
allowing the external video source for the video dis-
play unit to be selected using the AV selection keys
as well as the
RGB 1
and
RGB 2
keys.
This allows the video signal of different devices to be
hooked up directly to the monitor and switched to-
gether with the audio from one control surface (the
AV-452 or the RC-452).
An external IR “blaster” (not supplied) must be con-
nected to the AV-452 for control of the video display
unit.
Learning the external IR commands
In the
following explanation, we assume that the AV equip-
ment is hooked up to a multi-input video display
device in the following way:
Not shown here is the IR blaster device, connected to
the relay control
g
connector of the AV-452 and
pointing at the video monitor’s IR receiver.
Here we are programming the
DVD
key on the AV-
452 to switch the video monitor to the S-Video input.
1
Make sure the power to the AV-452 is OFF.
2
Set the
LEARN IR
switch (switch
1
) to
ON
.
3
Turn ON the AV-452. The
AMP A
,
AMP B
,
INTERCOM
and
CASCADE
keys on the front
panel flash to show the unit is in IR learn
mode.
4
Press the
DVD
key on the AV-452 front panel.
It starts to flash.
5
Point the video display device’s remote control
unit at the AV-452’s
IR SENSOR
H
and press
the key which enables the S-Video input on the
remote control unit of the video display device.
•
If a valid IR code is received and stored, the
DVD
key stops flashing.
•
If the IR code is not received and stored cor-
rectly, the
DVD
key continues to flash.
NOTE
The AV-452 only supports the NEC type IR command
specification. If the key continues to flash, and you are
sure that the source change command has been trans-
mitted, the video display device may not conform to the
NEC ITR command specification.
6
Press another AV selection key (for example,
the
RGB 1
key) and the corresponding input
key on the video remote control unit of the
video display device to learn this command.
7
When you have finished programming these
commands, set the
LEARN IR
switch (switch
1
)
to
OFF
.
The AV-452 resets itself and starts normal
operation.
