Installation

Step 1 — Mount

If desired, mount the switcher in a rack with the supplied rack ears or mount the switcher under a desk using an Extron MBU 149 1U Enclosure Under-desk mount kit, part #70-222-01.

Step 2 — Inputs

As applicable to your switcher, connect:

a Up to 4 or 8 S-video inputs to the input connectors.

—or — Up to 4 or 8 composite video inputs to the input connectors.

b Up to 4 or 8 unbalanced stereo audio inputs to the input RCA connectors.

— or — Up to 4 or 8 balanced or

unbalanced stereo audio inputs to

Step 3 — Outputs

As applicable to your switcher, connect:

a Up to 4 or 8 S-video or composite video devices to the output connectors.

b Up to 4 or 8 unbalanced stereo audio devices to the output RCA connectors.

Step 4 — RS-232 Connections

If desired, connect a control system or a computer to the RS-232 port. See the table below

Step 5 — External Sync

Step 6 — Connect power

Definitions

Tie — An input-to-output connection

Set of ties — An input tied to two or more outputs

Configuration — One or more ties or sets of ties

Current configuration — The currently active configuration (also called configuration 0)

Preset — A configuration that has been stored. One preset can be assigned to each input and output button. 16 presets are available via RS-232 control. When a preset is retrieved from memory, it becomes the current configuration.

Front Panel Features

Power/data/audio LED — Indicates power is applied. This LED also has two secondary functions:

Serial communication function — The Power/ data/audio LED blinks off and on to indicate that an IR signal has been received.

Audio level function — In Audio Setup mode, the Power/data/audio LED lights when the selected input audio signal is at or above the reference level and is unlit when the signal is below the reference level. Adjust the gain until the LED blinks frequently. If the LED is almost always lit, blinking off only occasionally, the level is too high. If the LED is almost always off, blinking on (lit) only occasionally, the level is too low.

I/O button (audio/video switchers) selects video and audio, video, or audio for input selection.

Video and Audio LEDs (audio/video switchers)

indicate whether video and audio, video, or audio is selected. The Audio LED blinks to indicate audio is broken away.

Input buttons select an input to tie to an output.

Input LEDs identify the input selected for the tie.

Output buttons select output(s) to tie to an input.

If desired, feed a black burst (genlock) signal to the external sync

IN connectors.
