moved. Care must be taken when connecting cables
to the barrier strips to avoid shorting the connections
to the shield.
INSTALLATION INFORMATION
POWER AND GROUNDING:
For your safety, we have incorporated a 3-wire line (mains)
cable with proper grounding facilities. It is not advisable to
remove the ground pin under any circumstances. If it is
necessary to use the equipment without proper grounding
facilities, suitable grounding adaptors should be used. Less
noise and greatly reduced shock hazard exists when the
unit is operated with the proper grounded receptacles.
INSTALLING THE RACK-MOUNT EARS
This unit can be rack mounted with optional rack mount
kit. To attach the rack-mount ears, simply remove the three
screws already in the front on either side of unit and align
the ears with the rack-mount flange forward of the unit .
Replace the screws and tighten securely, being careful not
to overtighten. The unit then mounts in a standard 2 space
19" rack. You may find it desirable to remove the rubber
feet from the bottom of the unit in rack-mount installations.
The rack-mount ears may also be used to secure the unit
in a shelf application to deter theft.
RACK-MOUNT RECOMMENDATION
To provide adequate ventilation, leave at least one rack
space between units when multiple amplifiers are mounted
in the same rack.

channel, one dedicated auxiliary channel, and one switch-
able microphone/auxiliary channel. Each microphone chan¬
nel shall feature one low impedance balanced input and
one high impedance input. The master section shall include
two EQ controls providing 10 dB boost ro cut at 100 Hz and
10 kHz and a "Contour" switch providing 10 dB boost at 100
Hz and 5 dB boost at 10 kHz. The unit shall provide selec¬
table automatic muting of the MIC 2/AUX 1 and AUX 2
channels with precedence given to the MIC 1 channel.
Connections for external mute shall be provided through
barrier strip connections on the back panel. Provision for an
external master volume control shall be made via barrier
strip connections on the back panel. Provision for an exter¬
nal master volume control shall be provided through barrier
strip connections on the back panel. The unit shall be pack¬
aged in a rugged metal chassis 15" wide by 3 1/2" high by
12 3/4" deep. The unit shall operate from standard 120 volts
AC, 60 Hz power. The internal power amplifier shall be
capable of delivering 35 watts into 4 ohms or 8 ohms, as
well as providing 25 volt and 70 volt line outputs. The unit
shall be capable of delivering rated power from 50 Hz to 18
kHz ±1.5 dB into 4 ohms at its direct output at 0.5% or less
distortion with system hum and noise at least 80 dB below
rated output from line level AUSX input. The unit shall be
called the Peavey Architectural Acoustics Division model
UMA™ 35T.
