Welcome
The PZS™140RA is a full-featured matrix mixer with four integral
35 Watt power amplifiers. The five-input, four-output architecture is
supported by a full mix matrix with microprocessor-based assignment,
store/recall functionality, front panel controls and support for the new
D-Series remote control network.
The compact 3U package features an intuitive front panel design with
easy access to zone assign buttons, EQ, input level and output drive
controls. Visual feedback is included for matrix routing assignment,
input and output audio level and paging mute for master channels.
Among the most exciting new features is integral support for the
D-Series D4S four-button control panel. The D4S provides remote
access to the PZS 140RA's matrix cross points and can be configured
for either "input to zone" (source select), or "zone from input" (zone
select) operation. Multiple D4S panels can be connected simultaneously
via the included D-Series RJ-45 network connector, making installation
simple and cost effective. The front panel assignment LEDs mirror
changes made by the remote controls, so monitoring the status of
remote operation is easily confirmed at the front panel.
The versatile PZS 140RA includes microphone and line level inputs
terminated on removable Euro connectors on each channel. In addition,
input Channels 3, 4 and 5 also include summing RCA connectors for
easily terminating consumer line-level sources for music playback
applications.
Integral gate dynamics are provided for vox ducking, with channels 1
and 2 configured as master inputs. These inputs feature additional front
panel benefits including a mute status LED and recessed threshold and
hold controls.
Each of the PZS 140RA's four output sections include a 35 Watt power
amplifier. In addition to a direct-coupled, 4 Ohm output, the PZS 140RA
also features transformer-coupled constant voltage (domestic: 25 Volt,
70 Volt; export: 70 Volt, 100 Volt) outputs, an 8 Ohm output and a
600 Ohm balanced line level output. All output section connections are
also on removable Euro connectors for easy installation and service.
The output section is supported by a simple front panel interface
including master level controls, signal presence and clipping LED
indicators and matrix bus assign buttons.

Cautions
Installation Precautions
The PZS™140RA is designed for shelf or rack-mount installation. The
unit is equipped with rubber feet for shelf or table top installations.
When using racks, we recommend commercial grade, EIA electronic
equipment racks. Installing this unit in non-EIA racks or in other
configurations is not recommended. Failure to install this product in
the proper enclosure may void your warranty.
The PZS 140RA is forced-air cooled, and care should be taken not to
block the air intake or exhaust path located on the sides of the unit.
When installed in EIA racks, the PZS 140RA requires a minimum of 2”
clearance on each side of the equipment rack for proper cooling. In
normal conditions, the unit can be installed in adjacent rack spaces
without additional venting. However, it is recommended that common
sense be applied to large installations where multiple units are mounted
in a single rack. It is generally accepted that a ratio of one vent for
every two units is a good rule of thumb for adequate performance. In
installations where adverse conditions exist, and room temperatures are
likely to rise, additional vents should be installed.
Several associated products may be used to complete a working system
using the PZS 140RA. This manual frequently makes reference to these
products, but does not provide specific configuration or installation
information on them. Please refer to the manuals on these products for
information. Every product must be properly installed for the PZS
140RA to operate in accordance with its published specification.
The information contained in this manual is subject to change without
notice. Peavey Electronics is not liable for improper installation or
configuration. The information contained herein is intended only as an
aid to qualified personnel in the design, installation and maintenance of
engineered audio systems. The installing contractor or end-user is
ultimately responsible for the successful implementation of these
systems.
The illustrations, drawings and renderings contained herein are NOT
drawn to scale.
The PZS 140RA can be installed
into any EIA rack with an internal
depth clearance of 18" or more.
This will allow plenty of space for
the unit and its associated wiring
harness at the rear of the rack.
Infrastructure is critical for imple-
menting reliable sound systems.
It is important that your conduit
systems, wire plants and connec-
tor complement are properly
designed and installed or your sys-
tem may perform at inferior levels.

Input Channel Features
Each input Channel of the PZS™140RA includes identical control and
status functions. In addition, channels 1 and 2 include additional
TRIGGER and HOLD controls as well as MUTE LEDs to indicate the
status of the page ducking feature.
ASSIGN - Momentary push button, used in conjunction with the Zone
Assign button, assigns the input Channel to any combination output
zones. See page 17 for information on zone assignment and
configuration.
ONE - Single-color, green LEDs indicate Channel to Zone assignment.
The input Channel is routed to an output bus when the corresponding
ZONE LED is illuminated.
MUTE - (Channels 1 & 2 only) Red LED indicates that the Mute bus is
active. When input Channel 1 or 2 is active, all other channels will be
muted or ducked, depending on the position of the TRIGGER and HOLD
controls.
HIGH - Rotary control adjusts the level of the Channel’s high frequency
filter. The filter center is at 10 kHz. The control adjusts the filter
amplitude from unity (0) to either -10 dB or +10 dB.
LOW - Rotary control adjusts the level of the Channel’s low frequency
filter. The filter center is at 100 Hz. The control adjusts the filter
amplitude from unity (0) to either -10 dB or +10 dB.
LEVEL - Rotary control adjusts Channel input level. The level control is
active after the first gain stage, just before the EQ section.
TRIGGER - (Channels 1 & 2 only) Recessed rotary control adjusts the
audio level required (threshold) to activate the internal ducking/muting
circuit. Adjusting this control clockwise decreases the level required to
activate the ducking/muting circuit. To bypass the ducking/muting
feature, place this control in the maximum counter-clockwise position.
HOLD - (Channels 1 & 2 only) Recessed rotary control adjusts the
release time of the ducking/muting circuit. Adjusting this control
clockwise will increase the time required for the ducking circuit to
release.
SIGNAL - Green LED indicates audio input signal level. The LED
monitors input signal after the first gain stage, just before the LEVEL
control. The LED will illuminate green when the signal level is above
-20 dBu.
“Hold” is the time interval between
the last detectable (set by the
TRIGGER control) audio signal and
the release point of the ducking
circuit. The HOLD control adjusts
the release point, increasing or
decreasing the hold time interval.

PAGE 12 PZS™-140RA User Manual
Rear Panel Features
Inputs
Each channel of the PZS™140RA includes line-level and microphone-
level inputs. These inputs are terminated to removable Euro connectors
for balanced connections to external audio circuits. For information on
how to terminate a Euro connector, please see page 15.
Channels 1 and 2 are “priority” inputs and include special functionality
that allow them to be used as vox-based paging priority channels. This
functionality is controlled from the front panel TRIGGER and HOLD
controls. (See page 10.)
In addition to the line and mic-level inputs, channels 3, 4 and 5 include
dual female RCA connectors that include an internal summing network.
These inputs should be used with stereo (two-channel) line-level
sources with a nominal output level of -10 dBm.
Digital Remote Control
The PZS 140RA supports the Peavey Architectural Acoustics D-Series
D4S remote control panel. The D4S connects directly to the PZS 140RA
via the rear panel DIGITAL REMOTE CONTROL connector. This connector
is a female RJ-45 jack designed to connect the controllers using
standard Category 5 (CAT5) cable.
For more information on the DIGITAL REMOTE CONTROL feature, please
see page 1 .
Phantom Power
Pressing the 48 Volt Sub-panel switch activates the 48 Volt Phantom
Power on Mic inputs 1 through 5.
Each channel can receive only one
type of audio input at a time.
Terminating more than one source
signal to a single channel simulta-
neously will result in unsatisfactory
performance.

PZS™-140RA User Manual PAGE 13
Zone Outputs
one Outputs
Each of the four PZS™140RA outputs includes identical features and are
labeled as “zones.” Both line-level and loudspeaker-level outputs are
provided. The power rating for the loudspeaker outputs is 35 Watts and
is transformer-coupled except for the 4 Ohm output.
XFMR - Each tap provides 35 Watts to constant voltage loads,
referenced to the COM connector. There are secondary transformer taps
for 70 Volt, 25 Volt and 8Ω loads (dom.) and 100 Volt, 70 Volt and 8Ω
loads (export).
DIRECT 4 OHM - This output is direct-coupled to the power amplifier
output and is referenced to ground.
600 OHM BAL OUT - Balanced 600 Ohm output for driving high
impedance sources. This signal is derived from the transformer
secondary and a passive line/impedance matching circuit. This output is
considered to be transformer-balanced and can be used simultaneously
with the loudspeaker-level output circuits.
The 600 Ohm BAL OUT output is
transformer coupled from the sec-
ondary of the output transformer.
This output can be used simulta-
neously with any of the other out-
puts.
Do not terminate more than one
transformer-coupled loudspeaker
output simultaneously. All trans-
former-coupled loads are refer-
enced to COM.

PAGE 14 PZS™-140RA User Manual
Connections
Connections
The PZS™140RA features a rear panel connection scheme and includes
the following connection types:
• Microphone-Level Audio Input
• Line-Level Audio Input
• Summing RCA Line-Level Input
• Digital Remote Control
• Transformer-Coupled Loudspeaker Output
• Direct-Coupled Loudspeaker Output
• Transformer-Coupled Line Level Output
Except for the Digital Remote Control and RCA Line-Level Inputs, all
connections are placed on Euro connector blocks designed for easy
termination, service and maintenance. The unit ships with a matching
pluggable connector for each header block. The preferred method for
making audio connections consists of four steps as detailed in the steps
below. All terminations are identical except for the connection type and
the number of conductors per circuit. As with any electronic connection,
care should be taken to ensure the termination is solid. For a proper
termination, there should be no stray wire strands, kinks or nicks in the
wire jacket. As always, audio connections should be made with high
quality stranded wire. Input connections should be shielded.
STEP 1. Carefully strip the cable jacket and the conductor insulation.
The distance between the end of the jacket and the tips of the
conductors should be approximately .750”. The strip length of the
conductor wire should be approximately .310” for proper termination
into the Euro connector.
STEP 2. Carefully insert each conductor into the opening of the Euro
connector. Take care to ensure that polarity is observed and that the
shield is properly twisted to make a solid connection. Ideally, the shield
should be isolated by installing heat shrink insulation.
STEP 3. While holding the cable so each conductor is firmly seated in
the connector, carefully tighten down each screw. While turning each
screw, look closely at the wire and make sure that the action of the
screw does not “push” the wire out of the connector. Verify the integrity
of your connection by gently pulling on each conductor to ensure that it
is terminated properly.
STEP 4. Take the completed wire/connector assembly and carefully
plug it into the matching connector header on the PZS 140RA’s rear
panel. Take care that you are plugging the connector into the proper set
of pins on the header. There is no barrier between adjacent audio
channels, so it is possible to connect to pins of an adjacent channel. If
you are not careful, instead of connecting to Positive, Negative and
Shield, you may end up connecting Negative-Shield-Negative. Your
finished connector for a single input circuit should look like the
illustration to the right.
The line-level Euro inputs will also
accept un-balanced circuits. To
terminate an unbalanced source,
use the ground and positive
terminals. It is NOT necessary to
use a jumper to bridge the shield
and negative conductor.

PZS™-140RA User Manual PAGE 15
Theory
Theory
The PZS™140RA is essentially a matrix mixer coupled with four 35 Watt
power amplifiers. To maximize the PZS 140RA for your application, it is
recommended that you have a solid understanding of signal flow, and
how the PZS 140RA provides processing, routing and output.
• INPUTS
The INPUT section includes five preamplifiers, each with their own
inputs and controls. The five inputs are basically stand-alone audio
blocks with a single output. The output terminates to the
microprocessor-controlled bus assign switches. (Each input has its own
set of bus assign switches.) The outputs of the switches connect
directly to the matrix buses.
• MATRIX
The MATRIX includes four buses that allows any of the five inputs to be
assigned to any of the four outputs. This assignment is configured by
using the ASSIGN buttons on the front panel. To simplify the
assignment process, there are buttons for each input and each output
in the matrix.
• OUTPUTS
There are four output sections. The key component of the output
section is the summing amplifier. All four of the matrix buses terminate
to the summing amplifier, which effectively is a 4x1 mixer at the front
of each output. The output section then drives the power amplifier
which includes direct and transformer-coupled output terminals.
The combination of the microprocessor-controlled switches at each input
section and the output summing amplifier creates the actual matrix
function of the PZS 140RA.

PAGE 16 PZS™-140RA User Manual
Operation
Operation
The primary function of the PZS™140RA is to operate as a matrix mixer,
as previously described. A matrix mixer includes “cross points” where
the input Channels are “connected” to the output buses, or in this case,
“zones”. Enabling the connection of the matrix cross point completes
the circuit between the input Channel and the output zone. (See block
diagram on page 22.)
Making this connection on the PZS 140RA is easy. Each input Channel
includes a momentary button and four-LED array. Each Zone includes a
single button. The cross point connection is enabled by using both the
Channel and Zone buttons.
To assign an Channel to a Zone, press and hold the ASSIGN button on
the desired Channel. While holding the button down, press and hold the
ASSIGN button on the target Zone until the corresponding Zone LED
illuminates on the channel’s LED array. Release both buttons to com-
plete the assignment.
The key to Zone assignment on the PZS 140RA is the LED array on
each input channel. The LEDs tell you to which output Zone the Channel
is assigned. Any combination of output assignment is possible, so more
than one LED can be illuminated.
To clear, or “dis-assign” an input channel to an output Zone, follow the
same process until the corresponding LED is OFF.
To assign an input channel to multiple Zones, follow the same process
for each output Zone.
The illustration below shows a PZS 140RA with channel 1 assigned to
Zone 2 and Zone 3, channel 2 assigned to Zone 1 and channel 3
assigned to Zone 4. Channels 4 and 5 are not assigned.

PZS™-140RA User Manual PAGE 17
Configuration
Use the Setup/Recall feature to
provide the end-user a “safety
net”. If the zone assignments are
altered, they can easily be
restored by recalling the original
configuration.
In the event of a power loss, using
the Recall feature is not necessary
to restore settings. The PZS 140RA
will revert to the last configuration
when power is restored; therefore,
no additional action is required.
Setup/Recall
On the front panel of the PZS™140RA, you will notice a small, recessed
button labeled “Setup/Recall”. This button provides access to
functionality that enables you to store a “snapshot” of the matrix
assignment buttons and recall them easily in the event of an
inadvertent reassignment.
The Setup/Recall feature includes two basic functions:
•Store
•Recall
The Store function allows you to write the current input assignment
locations to the PZS 140RA’s internal flash memory. This memory is
non-volatile, which means that even without power, the memory is
secure. The file that is written to memory includes the position of the
Assign buttons for each input Channel.
To store this file, follow these steps:
1. Configure the PZS 140RA for the zone assignment you wish to store.
Refer to page 17 for details on operation.
2. Using a small pen, or other instrument, press and hold the
Setup/Recall button. After a few seconds, the Mute LEDs on channels 1
and 2 will flash. Continue holding the button down until the flashing
stops.
3. Release the button. The configuration file is now written.
To recall this file, simply press (do not hold) the Setup/Recall button.
The LEDs will flash momentarily, indicating that the file was recalled
successfully.
The Setup/Recall feature stores a single configuration file. Usually, this
file would include the default configuration assignments for a project.
An example of this would be a restaurant, where the installing
contractor has assigned the input Channels to restaurant zones per
his/her contract. During normal use, the restaurant staff reassigns
certain inputs, but later realizes that the original configuration needs to
be restored. The Setup/Recall feature provides this functionality.

PAGE 18 PZS™-140RA User Manual
Configuration
When using the D4S with the PZS
140RA, the buttons always operate
as switches, and thus are not
mutually exclusive. This allows full
matrix assignment, just like the
front panel of the PZS 140RA.
Refer to the D-Series User Manual.
Remote Control Configuration
The PZS™140RA includes limited support for the D-Series remote
control network. Although the network is supported, only the D-Series
D4S is operable for the PZS 140RA. The D4S is a four-button, flush-
mount panel that can be configured to provide remote access to the
PZS 140RA’s matrix/assign functionality. Using the D4S provides a
simple way to provide a remote location access to input or zone
selection.
The D-Series network uses a system of Base Addresses to identify
control function on the network. You can connect up to 32 D4S panels
on a single PZS 140RA, but only eight Base Addresses are supported.
This means that you could have many duplicate panels operating in
“parallel” up to the 32 panel, eight Base Address limit. For more
information on the D-Series system, please refer to the D-Series User
Manual.
When a D4S panel is configured for input channel operation, the
buttons allow for zone selection. Conversely, when the D4S is
configured for zone operation, the buttons provide input channel
selection.
Although the D-Series network includes 32 Base Address options, only
eight are supported on the PZS 140RA. Assigning a D4S to one of these
eight Base Addresses will configure the panel as follows:
