and the input devices.
Set the audio gain and attenuation. See the "Set input
5
audio level" SIS commands in chapter 4, "Remote Control".

Mounting the Switcher

C Installation and service must be performed by
authorized personnel only.
The 1-inch high, quarter-rack width switcher can be placed on
a tabletop, mounted on a rack shelf, mounted under a desk or
tabletop, or mounted on a projector bracket.

Tabletop placement

Affix the four included rubber feet to the bottom of the unit and
place it in any convenient location.

Rack mounting

For optional rack mounting, mount the switcher on any of the
following rack shelves:
• RSF 123 3.5-inch deep rack shelf kit (part #60-190-20)
(figure 2-1, on the next page)
• RSB 123 3.5-inch deep rack shelf (part #60-604-21)
• RSU 126 6-inch deep universal rack shelf kit (part #60-190-10)
• RSB 126 6-nch deep basic rack shelf (part #60-604-11)
• RSU 129 9.5-inch deep universal rack shelf kit
(part #60-190-01) (figure 2-2, on page 2-4)

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.
