SW RGB and YUV A Switchers • Introduction1-2

Features

Audio switching models

Inputs — These switchers input 2, 4, or 6 stereo audio signals, balanced or

unbalanced, on 3.5 mm, 5-pole captive screw terminals.

Outputs — The selected audio input is buffered and output, balanced or

unbalanced, on a 3.5 mm, 5-pole captive screw terminal.

Audio gain/attenuation — Users can set the input level of audio gain or

attenuation (-18 dB to +24 dB) via the RS-232 link or from the front panel, to
be compatible with a wide range of line level (from -20 dBV to +4 dBV).
Individual input audio levels can be adjusted so there are no noticeable
volume differences between sources (figure 1-2) and for the best headroom
and signal-to-noise ratio. This function also eliminates the need for separate
preamps or attenuators when used with professional (higher line level) and
consumer (lower line level) audio equipment.

Introduction, cont’d

All models

Bandwidth — Bandwidth is 350 MHz (-3 dB). This high bandwidth allows the

switchers to switch all of the high-resolution video signals with no loss of
signal quality.

Input signal sensing — The switcher continuously monitors all inputs to sense

when the input signal is active or inactive. The switcher reports changes in
the status of each input (active to inactive or inactive to active) on the RS-232
port.

Autoswitching mode — When autoswitching is enabled, the switcher continuously

monitors all inputs and automatically switches to the highest-numbered
input with video sync pulses present. If video is absent from all inputs, no
input is selected.

Operational flexibility — The operator can select the input and set the audio gain

and attenuation for each input using the front panel buttons or via the
switcher’s Remote port RS-232 link. The RS-232 link allows remote control
via a PC or control system. The operator can select inputs via the switcher’s
contact closure link on the Remote port. The operator can also remotely
control the switchers using a contact closure keypad connected to the Remote
port or an Extron IR 102 Universal remote control kit (part #70-224-01)
connected to the Remote port.

Rack mount — Rack mountable in any conventional 19" wide rack with the

supplied rack ears. The two SW2 models require an optional 1U Universal
Rack Mount Kit (part #60-190-01) for rack mounting.

Power supply — Includes an internal 100 VAC to 240 VAC, 50/60 Hz, 20 watts,

auto-switchable power supply, which provides worldwide power
compatibility.

you should be able to switch from one input device to another. If this does
not happen, double check steps 3 through 5 and make adjustments as needed.

Mounting the Switcher

Rack mounting the switcher

The SW2 switcher models are housed in half-rack width 1U high metal enclosures
that can be rack mounted with an optional 1U Universal Rack Mount Kit or 1U
Basic Rack Shelf (part #60-190-01 or 60-604-01). The SW4 and SW6 switcher models
are housed in rack-mountable, 1U high, 17" wide metal enclosures. The
appropriate rack mount kit is included with the SW4 and SW6 switchers. Rack
mount the switcher as follows:

SW2 models

1. If rubber feet were installed on the bottom of the switcher, remove them.

2. Place the switcher on one half of the optional 1U (one unit high, 19" wide)

rack shelf (part #60-190-01). Align the front of the switcher with the front of
the shelf, and align the threaded holes on the bottom of the switcher with the
holes in the rack shelf (figure 2-1).

3. Secure the switcher to the rack shelf with the two provided 4-40 x 3/16"
machine screws. Insert the screws from the underside of the shelf, and
securely fasten them through diagonally opposite corners as shown in
figure 2-1.

4. Fasten the false front panel (provided with the rack shelf) to the unoccupied
side of the rack (as shown in figure 2-1), or install a second half-rack-width
device in that side by repeating steps 1 through 3.

5. Secure the rack shelf to the rack using four 10-32 x ¾" bolts. Insert the bolts
through #10 beveled washers, then through the holes in the rack ears.

SW4 and SW6 models

1. If rubber feet were installed on the bottom of the switcher, remove them.

2. Attach the rack mount brackets to the switcher with eight #8 machine screws,

provided (figure 2-2).

3. Insert the switcher into the rack, align the holes in the mounting bracket with
those of the rack.

4. Secure the switcher to the rack using the supplied machine screws.
