INSTALLATION INFORMATION
INSTALLING THE RACK-MOUNT EARS
This unit can be rack-mounted with an optional rack-mount kit. To attach the rack-mount ears, simply remove the three
screws already in the front on either side of the 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 two-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.
ARCHITECTURAL AND ENGINEERING SPECIFICATIONS
The mixer amplifier shall have two microphone/line inputs, one line input, and one dedicated Page input. Channel 1
shall have screw terminals and an XLR connector for the Low Z input; screw terminals for the High-Z input. Channel 2
shall have screw terminals for the Low-Z input; screw terminals and RCA phono connectors for the High-Z inputs.
Channel 3 shall have RCA phono connectors. Channels 1 and 2 shall have 15 volt phantom power for the Low-Z
inputs. The Page input shall be transformer balanced (600 ohms) and shall have screw terminals for the input connec-
tion.
The master section shall include one Master Volume level control, two EQ controls providing 10 dB boost or cut at
100 Hz and 10 kHz, and a "Contour" switch providing 6 dB of boost at 100 Hz and 10 kHz.
The unit shall have two levels of automatic muting. Mute 1 shall give precedence to the Page input, and it shall over-
ride Channels 1 through 3, with a threshold control on the Page input. Mute 2 shall give precedence to Channel 1, and it
shall override Channels 2 and 3, with a threshold control on Channel 1. The two mute lines shall have screw terminals
for external mute control.
The unit shall have a Channel 3 output that provides an RCA phono, non-mutable output of Channel 3. Provision for an
external master volume control shall be made via screw terminals.
The unit shall be packaged in a rugged metal chassis 17" wide by 3-1/2" high by 15-5/8" 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 and 8 ohms, as well as providing 25 volt and 70 volt balanced line outputs. The unit shall be capable of deliver-
ing rated power from 20 Hz to 20 kHz
±
1.5 dB into 4 ohms at its direct output at 0.5% or less distortion with hum and
noise at least 80 dB below rated output from line level inputs. The unit shall be called the Peavey Architectural Acous-
tics Division model UMA™ 35T
