RANAVMS2 Stereo Audio/Video Multiplexer

Module

The

RANAVMS2

is a stereo audio/video multiplexer module that combines a media

resources' audio and video signals onto one 75 Ω coax cable. This cable then connects

to the video matrix switch, which then passes the signal over another 75 Ω coax cable

to the classroom. The

RANAVMS2

consists of two multiplexer modules on one

board allowing two resources to be connected to one

RANAVMS2

. These stereo

audio/video multiplexer modules are housed in a

RANCAGE

card cage with a 12

VDC

at 400 m

power source.

Parts Required

1 75 Ω video cable with Phono-to-Phono connectors (refer to drawing

2377) or

Phono-to-

BNC

(refer to drawing

2376) for

RANVFLOP

and

RANSVHS

2 Phono-to-Phono audio cable (refer to drawing

2385). Separate left and right leads

for stereo sources. Mono audio sources will only need one cable.

1 75 Ω video cable with Phono-to-

BNC

connectors for composite out to the video matrix

switch input (refer to drawing

2376)

Associated Equipment

RANCAGE

Card Cage (see “

RANCAGE

” for more information)

RANPS12

Power Supply

1 Media device (e.g.,

RANVCR

RANCDI

RANLASER

RANVFLOP

, or

RANMENU

)

Installation

Remove the front cover panel of the

RANCAGE

card cage.

Insert the

RANAVMS2

into the front of the card cage along the card guides (located on

the top and bottom of the card cage) until it snaps into place.

Place the resource (e.g., a

VCR

Player) onto its appropriate rack shelf. Now place the

device and shelf into the rack.

Route a video cable from the media device's “Video Out” jack to the “Video In” jack

on the

RANAVMS2

module that you have designated for this device.

If this device has audio, route the audio cables from the media device's Left and Right

“Audio Out” jack to the corresponding “Audio In” jacks on the

RANAVMS2

module

that you have designated for this device. This must be the same module that you have

chosen for the video feed from that device. If it is a mono unit, select the Right audio

input on the

RANAVMS

Set the Stereo/Mono switch on the

RANAVMS2

to the appropriate setting for the

device. For devices without audio, select “Mono.”

Set the Audio Impedance switch to the appropriate settings for the device that you are

using. Most devices use the 600 Ω setting. Use the 10kΩ setting for devices whose
