Modular Mixer/
Power Amplifiers
| Description | 3
The University 9000-series
mixer/power amplifiers provide
wide frequencv response, low noise,
low distortion and extremely flexible
user-configurable features. They are
ideal for use in sound systems for
churches, schools, auditoriums,
business/industrial environments,
background/foreground music
systems and paging systems of any
type.
As many as six optional mod-
ules may be installed in the ports in
the rear panel. Front panel controls
are used to adjust the signal level of
each input and a master volume
control adjusts the overall output
level of the combined input signals.
Bass and Treble tone controls allow
tailoring of the frequency response
of the unit. A front panel pushbutton
switch allows defeating the tone
controls (a rear panel adjustable EQ
bypass control permits setting the
maximum range of tone control).
Two mute busses give the user
great flexibility in determining
which signals should be muted
when paging or when other mute-
related functions are used. The mute
busses are accessible via terminals
located on the rear panel; bus
selection is accomplished by
installing or removing internal
jumpers in the 9000 series modules.
(See the 9000 Series Modules data
sheet for details.)
A MASTER VOLUME control,
combined with the OUTPUT LEVEL
meter, permits ease of adjustment of
the combined Input signal levels to
the power amplifier for optimum =
output. 3
The power amplifier section
includes thermal, dc-offset and
current-limiting short-circuit protec-
tion to help prevent amplifier or
speaker damage due to miswired,
open or shorted speaker lines or
amplifier overheating. The amplifier
is muted when switched on to
prevent speaker damage from “turn-
on thump.”

| Architects’ and Engineers’ Specifications |
The unit shall comprise an integral
single-channel power amplifier with a
six (6) channel mixer packaged in a
single free standing chassis which may
also be mounted in a 3-unit high x 19-
inch wide standard EIA equipment rack
space. The amplifier section shall be
capable of delivering (30, 60 or 120)
watts continuous average sine wave
power, directly coupled into a 4 ohm
load. Transformer coupled outputs shall
also be included for driving 8 ohm,
25 voltor 70.7 volt loudspeaker loads.
The amplifier outputs shall be con-
nected to the load via a screw terminal
strip. Total harmonic distortion at rated
output shall be less than 0.02% at
1 kHz. The direct output frequency
response shall be within a tolerance of
+1 dB from 20 Hz to 20 kHz. The
transformer output frequency response
shall be within £1 dB from 20 Hz to
15 kHz, or +1, -3 dB from 20 Hz to
20 kHz. The amplifier shall be provided
with current limiting circuitry for short
circuit protection, an automatically
resetting thermal breaker on the power
transformer, and fuses for both the
output and the AC line.
The construction shall allow for
optional plug-in input modules of
varying functions, each having a
nominal dimension of 3.07 inches high
by 1.38 inches wide by 3.10 inches

deep and a dual 6-pin edge connector
for 24 V DC power input as well as
audio and control connections. Various
modules shall be available with active
balanced input circuitry or transformer
isolated input circuitry, There shall be
two independent muting busses, and
plug-in jumpers shall enable either or
both busses for any given module
(where applicable).
The rear panel shall include a switch
to connect the preamp to the power
amp, or to allow the signals to be routed
through an external processor, mixer,
etc. It shall also include an in-out
switch for a built-in 60 Hz, 6 dB/octave
low cut filter, and a continuously
adjustable control to set the maximum
depth of the equalization (tone controls).
There shall also be terminals for remote
control of the two muting busses,
allowing for independent muting control
from two different places of appropri-
ately equipped input modules. Remote
control of the master volume shall also
be possible, via an external resistor.
With tone controls defeated, the
overall preamp/power amp signal-to-
noise ratio shall be at least 77 dB
(master at maximum), 90 dB (master at
minimum), or 100 dB S/N for the power
amp only. The standard input ports (card
connectors for the input modules) shall
be rated at nominal 100 mV sensitivity
— SRN
and 10 kohm input impedance. A
bridging input/output phono jack shali
be provided for linking two mixer/
amplifier units, shall have nominal
100 mV sensitivity, and 3.3 kohm
nominal impedance. The power amp
input shall be rated at 1 volt sensitivity
(to drive it to rated power), with
10 kohm impedance. The preamp and
aux outputs shall be phono jacks rated
at 1 volt nominal level, having 600 ohm
and 10 kohm nominal impedance re-
spectively.
Operating temperature range shall be
from —10°C to +60°C (+12°F to
+140°F). The power line requirements
shall be 120 volts AC, 60 Hz, at
60 watts max. (30 watt model!) or
100 watts max. (60 watt model) or
180 watts max. (120 watt model). The
dimensions of the unit shall be as
follows: 5.2 inches (13.2 cm) high
without feet, 5.7 inches (14.5 cm) with
feet, 16.5 inches (42.0 cm) wide,
12.4 inches (31.5 cm) deep. The unit
shall have a black painted steel chassis,
and a black anodized and brushed
aluminum front panel with white no-
menclature. The mixer/amplifier shall be
a University Model 9003 (30 watt),
Model 9006 (60 watt) or Model 9012
(120 watt).
