Overview And Uses

AV4X-R

Stereo Audio

Composite Video

4X1 Switcher

With IR Remote Control

& RS-232 Serial Port Option

The AV4X-R is a 4-Input to 1-Output, 3 channel

switcher. Two channels for Stereo Analog Au-

dio and the third channel for Video or Coax Digi-

tal Audio.

The circuitry inside the AV4X-R uses only the

best components for ZERO degradation of au-

dio and video signals. The IC’s used for each

signal path are specifically designed for the type

is signal being switched. The result is a very

low noise/distortion and flat frequency response

output for both Audio and Video.

Typical applications include combining 4 differ-

ent A/V sources such as VCR’s, DVD’s and

Camcorders to one common output.

Although the AV4X-R is primarily used for

switching Stereo Audio and Video, the video

channel can be used to switch Coax Digital Au-

dio. This arrangement would allow both types

of audio (Analog and Digital) to be switched at

the same time. Perfect as a 4 input expansion

for any Hi-End Audio System.

Control of your AV4X-R is provided through a

front panel switch which cycles through the in-

puts. It is also used to program the Remote

Control characteristics.

The AV4X-R also comes with a Remote-Control

to directly access any of the 4 inputs. If you

have a Universal Remote such as the Philips

Pronto, please visit www.inday.com for Configu-

ration Files to simplify programming this device

into a system.

For advanced integration, the AV4X-R also has

an RS-232 Serial Control Port. This allows the

unit to connect to any Computer for direct con-

trol and status. See “RS-232 Control” section

for further information.

Remote Programming

Troubleshooting

The AV4X-R uses the same

remote as our RGB4X-R com-

ponent video switcher. If this

causes a conflict in your sys-

tem, please contact the factory

for other code options.

The Remote Control has 10

buttons. Only 5 of which are

active at one time. The unit

comes programmed to re-

spond to the left side column of

buttons. You can program the

unit to switch using the right

side buttons, if desired. This

facilitates using two AV4X-R’s

in a system and having inde-

pendent control over both.

Perform the following to repro-

gram the AV4X-R:

1-Remove power from the unit

by unplugging the 12VDC Con-

nector

2-Press and hold the front

panel button

3-Apply power to the unit.

4-Release the front panel but-

ton after the display stops

blinking.

Each time you perform this

operation you are alternating

the button group used on the

IR remote.

Q: Can I switch Coax Digital Audio using the

video channel.

A: Yes. Coax digital Audio is just AES/EBU digi-

tal audio that is designed to run over Coax

cable just like video and therefore can be

switched the same way

Problem: I now have noise or interference in the pic-

ture that was not there before.

Fix#1: The problem may be “cheap” cables. The

RGB4X is extremely wideband. The switching IC’s are

rated at 700MHz. That’s is 166 times the normal band-

width of composite video (NTSC). If you use marginal

cables with poor shielding, external RF interference will

penetrate the cables and may cause this interference.

Consider your cables to be like your water plumbing. If

they leak, you have a problem! You can fix this problem

by using a quality coax cable, such as type RG59.

Fix#2: Ground Loops can also cause noise and hum

bars. Try lifting the ground leads of your equipment by

using a “cheater plug”. This is a 2 prong AC adapter

without the ground prong, available at most hardware

stores.

RS-232 Control

RS-232 serial control is provided through a 3.5mm

stereo jack on the rear panel. A 3.5mm to DB9 cross-

over cable is provided. Any Terminal communications

program such as Windows “HyperTerminal” will work

for control.

Communications parameters are: 9600,N,8,1. See

specifications for wiring information.

Once connected, pressing the Enter key will cause the

AV4X-R to respond with its help message:

“AV4X-R Online! Type "S" for Status,

Numbers 1-4 for control.”

For current status, type the character “S” followed by

the “Enter” key. The current input is returned.

To switch inputs, type numbers 1, 2, 3 or 4 then

“Enter” . The unit will switch inputs and return a status

message.

All other characters will return the help message.

If the AV4X-R is in a powered-off mode via the IR re-

mote control, any Serial port activity will restore power.
