DESCRIPTION:

The Peavey Architectural Acoustics
PZSª140 is a five-channel mixing
system with assignment capability
to four independent powered zones.
Each channel offers low and high
equalization, channel level control,
signal presence LED, 48 volt phantom
power and zone assignment
switching. Channels one and two
offer low-Z (XLR) and detachable
screw terminal microphone inputs
(high and low-Z) for paging capability
with channels three through five
offering dual (paralleled) RCA jacks
and detachable screw terminal inputs
(high and low-Z) for use with various
music sources. Additionally, channels
one and two have recessed screw­driver controls for background music
ÒduckingÓ threshold and hold time
adjustments. Each zone has a master
level control, signal presence and clip­ping LED indicator, and detachable
screw terminal connections for pre­amp out/power amp in and balanced
line output. Each zone power amp is
rated at 35 W RMS and provides a

4-ohms (direct output), 8-ohms, 25 V
and 70 V (transformer isolated
outputs).

ARCHITECTURAL AND
ENGINEERING SPECIFICATIONS

:

The mixer amplifier shall have five
input channels each with assignment
capability to four independent
powered zones. Each channel shall
contain low and high frequency equal­ization, a level control, 48 volt phan­tom power, signal presence LED and
zone assignment switches.

Channels one and two shall be config­ured for paging with balanced low-Z
XLR and detachable screw terminal
block inputs (high and low-Z). These
channels shall also have front panel
recessed screw driver controls for
background music ÒduckingÓ threshold
and hold time adjustments. Channels
three through five shall be configured
for use as background music feeds
with dual (paralleled) RCA jacks and
detachable screw terminal inputs

(high and low-Z). All five channels,
however, are capable of being used
with mic or line level sources.

Each zone shall have a master level
control, signal presence and clipping
LED indicators, and detachable screw
terminal connections for preamp out­put/power amp input and balanced
line output. Each zone power amplifier
shall be rated at 35 W RMS continu­ous and shall provide a 4 ohm direct
output and transformer isolated 8
ohm, 25 V and 70 V outputs. The unit
shall be packaged in a rugged metal
chassis 5 1/4" high, 19" wide and 15"
deep, and shall weigh 34 pounds. The
unit shall be rack mountable and will
fit in a standard 19" rack requiring
three rack spaces. The unit shall
operate from 120 V AC 60 Hz power
and consume no more than 375
watts. The unit shall meet or exceed
all the published specifications. The
unit shall be a Peavey Architectural
Acoustics Division model PZS 140
mixer/amplifier.
