audio / video switchers
AUDIO / VIDEO SWITCHERS
Extron's Audio/Video Switchers (A/V SW) are compatible with NTSC/PAL/
SECAM video, S-Video and stereo audio. A/V SW features, models and part
numbers are shown in the table to
the right. AUTO (Auto switch)
models automatically select the
highest input when in Auto mode.
All A/V SW models are housed in
gray, 1U (1.75 inch height) metal
enclosures and can be rackmounted. The internal autoswitchable 100-240 volt power
supply is standard for world-wide
compatibility.

Installing Captive Screw Audio Connectors
Captive screw connectors must be wired to the audio cables using the captive
screws as shown in X below. Three methods of wiring the audio connectors for
input and output are shown in Y below. The top connectors are input examples
with output examples below. Use Z below when making connections for the
switcher from existing audio cables. The round audio connectors are shown
with the top one (tip and sleeve only) for unbalanced audio and the bottom one
(tip, ring and sleeve) for balanced audio. The "ring", "tip" and "sleeve" markings
are also used on the captive screw audio connector diagrams in Y. Together,
these examples may be used as a guide for making audio cables.
