The switchers are compatible with NTSC 3.58 and 4.43, PAL,
and SECAM video, and feature a 150 MHz bandwidth at -3 dB,
fully loaded. When external sync is applied (to Input 1), video
switching occurs during the vertical interval, providing glitch­free switching when all sources are genlocked.

All models feature front panel controls as well as an RS-232
connector (3-pin captive screw) to permit external remote
control.

The MMX 42 switchers distribute any of four video and/or
audio inputs to either or both outputs. The MMX 62 switchers
distribute any of six video and/or audio inputs to either or
both outputs. Any input can be switched to either or both
outputs. The RCA models route unbalanced stereo audio and
the AV and SVA models route balanced or unbalanced stereo
audio. The audio switching can either be linked with the video
(audio follow) or independent of the video (audio breakaway).
Adjustable audio gain and attenuation (available via RS-232
control) compensates for level differences between audio inputs.

UL guidelines

The following Underwriters Laboratories (UL) guidelines
pertain to the installation of the matrix switcher into a rack.

1. Elevated operating ambient temperature — If the

equipment installed in a closed or multi-unit rack
assembly, the operating ambient temperature of the
rack environment may be greater than room ambient
temperature. Therefore, install the matrix switcher in
an environment compatible with the maximum ambient
temperature (TMA = 122 °F , +50 °C) specified by Extron.

2. Reduced air flow — Install the equipment in a rack so that

the amount of air flow required for safe operation of the
equipment is not compromised.

3. Mechanical loading — Mount the equipment in the rack

so that a hazardous condition is not achieved due to
uneven mechanical loading.

4. Circuit overloading — Connect the equipment to

the supply circuit and consider the effect that circuit
overloading might have on overcurrent protection and
supply wiring. Appropriate consideration of equipment
nameplate ratings should be used when addressing this
concern.
