Once you have provided proper AC power to the amplifier, you may now connect to the inputs and outputs.
Remember to do this while the power to the unit is turned off (Power LED are not lit). The rear panel of your GPS
Series amplifier provides a central location for all input and output connections. Regardless of the GPS model, all
input connections are located at the bottom-center portion of the rear panel and all output connections are
located at the top-center portion. In addition, your amplifier can operate in either stereo or bridged (mono) mode.
All GPS Series amplifiers have DDT compression. However, only GPS models 900 and 1500 have a switch to defeat
this feature. This section will describe these areas of your GPS Series amplifier in detail.
MMooddee SSeelleeccttiioonn
44.. MMooddee sswwiittcchh
This switch determines which mode your amplifier will operate in. Before connecting your input signal and
spea er cables to the amp, you must determine how you want the amp to function. Two modes of operation
are offered on your amplifier, stereo or bridged (seperate).
Stereo:
When we use the term “stereo” we are referring to two channels, not necessarily left and right. Therefore,
in “stereo” mode there are essentially two power amps regardless of input type. You may use a stere input,
one stereo input to each channel of the GPS, or you may send two mono inputs to the GPS in the same
manner. A good example of two separate inputs would be the use of one channel for mono mains and one
channel for mono monitor signals. In order to select the “stereo” mode of operation you must place the
Mode Switch in the “out” position. In this mode, Channel A Output is supplied by the Channel A Input.
Channel B Output is supplied by Channel B Input.
Bridged or Mono:
In the “bridge” mode the two channels of the amplifier combine to form a single mono channel. The benefit
of using your amplifier in this mode is that the power is doubled. Refer to the specifications in this manual
for detailed output power specs on your specific model. To use the GPS Series amp in “bridge” mode, place
the Mode Switch to the “in” position where the switch remains down. The amp is now a mono amplifier and
only requires a single input. Plug your input signal into Channel A only for “bridge” mode operation.
Channel B input must not have anything connected.
Note for GPS 900 and 1500:
When these models are switched to “bridge” mode, the Power LED (3) for Channel B will no longer
illuminate.
NNoottee:: Refer to the Outputs section for an explanation of how the Mode Switch affects the spea er outputs.

The female XLR inputs are connected to dual OP AMP circuitry which offers very low noise and extremely
high common mode rejection ratio to minimize outside interference!
The female 1/4" phone jac input in the center of the “combo” connectors are also connected to a unique
“quasi-balanced” input circuitry. When used, these 1/4" jac s are not “chassis grounded” but connected to
ground through a relatively low impedance circuit which is part of a “ground loop” elimination circuit
associated with the input. This will normally allow “hum free” operation when relatively short 1/4" cable
patches are made to this input by various outputs from other equipment that share the same rac with this
amp. This “quasi-balanced” circuit is “automatic”, and is virtually invisible in normal usage. It cannot be
defeated. Use only a two-conductor (TS) phone plug when connecting to the 1/4" input of this connector.

These GPS Series amplifiers offer both XLR electronic balanced and phone jac balanced/unbalanced
inputs for each channel using Neutri 's new “combo” connector to save panel space.
The female 1/4" phone jac input in the center of the “combo” connectors is also connected to a unique
balanced/unbalanced input circuitry. When used, these 1/4" jac s can accept both unbalanced two-
conductor (TS) and balanced three-conductor (TRS) inputs. Balanced operation is always recommended for
optimum signal-to-noise. If unbalanced operation is a required, always eep the input cable to a minimum
length to avoid excessive noise.
66..CChhaannnneell BB CCoommbbiinnaattiioonn IInnppuutt
This connector is identical to the Channel A Combination Input (5) except it is not used during “bridge”
mode [See Mode Switch (4).]
77..IInnppuutt PPoollaarriittyy
Located between the Channel A and Channel B Inputs is a recessed Input Polarity switch (7) that allows the
user to select the desired polarity (phase) of the XLR inputs. This switch is a push-push type and a small
diameter “tool” is required to select the desired position. Set to the out (default) position, the polarity is
pin #3 positive, pin #2 negative, and pin #1 ground. This is the polarity found on most Peavey power
amplifiers. Although this is not the world “standard” (IEC) polarity, it was chosen by Peavey more than 20
years ago, and thus we offer this polarity to be consistent with products both past and present. If this
amplifier is used with other competitive products which use the IEC standard polarity, then the “in”
position of switch (7) should be selected yielding pin #2 positive, pin #3 negative, and pin #1 ground. As
with any electronic gear, polarity (phasing) is important because the loudspea er enclosures associated
with this power amplifier must be in phase with any other loudspea er enclosures associated with other
power amps. If one loudspea er system were to “push” while the other “pulls”, a serious sound
“cancellation” could result. Changing the setting of the polarity switch has the same effect as reversing the
polarity of the loudspea er connections at the output.
88..TThhrruu
Each channel has a female phone jac (8) labeled “thru”. This Thru jac offers very flexible patching
capability. When the XLR input of the combination connectors (5 and 6) are used, this THRU jac is the
output of the electronic balanced input circuitry, and as such can be used as a “line out” to connect to the
other input jac on this amplifier or other amps in the same rac . Thus, one balanced mixer feed can be
connected to the amp via the XLR connector and then further distributed (unbalanced) locally via the THRU
jac . Alternatively, when the 1/4" phone jac input of the combination connectors (5 and 6) is used as the
input, the THRU jac becomes a “bridged” input to it (similar to a Y-cord), again allowing this input signal
to be patched to the other input jac on this amplifier or other amps in the system. IImmppoorrttaanntt::The THRU
jac is not intended to be an “input”, and inadvertent usage as such will result in excessive loading of the
input source. Although not a catastrophic mista e, it will cause a significant reduction in “system gain” due
to the loading, and will seriously limit the overall system performance.

Each GPS Series amplifier offers two separate output sections featuring parallel outputs. The type of
output jac differs from model to model. Find the model and AC supply voltage of your unit to identify
which description is applicable to your product.

These two models feature 1/4" output jac s located on the top-center of the rear panel. There are two

1/4" output jac s, Binding Posts (10) are also provided for each channel.
AAllll ootthheerr GGPPSSmmooddeellss::
These models offer dual Spea on®Quic Connectors. The Spea on®is a four-wire connector with the
connections labeled as 1+, 1-, 2+ and 2-. The Spea on connectors found on your GPS Series amplifier are
connected with pins 1+ and 2+ wired in parallel to the positive output. Pins 1- and 2- are wired in parallel to
the negative output. This is typical for each channel.
NNOOTTEE::Consult your loud spea er specifications to determine the wiring configuration that will best suit
your system. The diagrams on pages 13 and 14 display the recommended hoo up for your GPS Series
amplifier. In addition to the Spea on®Quic Connectors, Binding Posts (10) are also provided for each
channel.
1100..BBIINNDDIINNGG PPOOSSTT OOUUTTPPUUTT CCOONNNNEECCTTOORRSS
Five-way binding post spea er outputs can be found on each channel regardless of model. For each
channel, the outputs are in parallel, hence the spea er connection cables can be terminated with banana
plugs or stripped wires for use in the binding post terminals as well as the output connectors (9). For
sustained high power applications, the use of the binding post terminals is recommended; however, care
must be exercised to assure the correct spea er polarity. The red binding posts are the signal outputs from
each channel, and the blac binding posts are chassis ground. The red binding post should be connected to
the positive inputs of the associated loudspea ers. For “bridge” mode operation, only the red binding
posts are used, and the associated loudspea er load is connected between the two red binding posts. The
9

red binding post associated with Channel A should be considered the positive output for the system and
thus should be connected to the positive input of the associated loudspea er system.
WWAARRNNIINNGG:: Regardless of what connections are used, the minimum parallel spea er load should always be
limited to 2 Ohms per channel or 4 Ohms “bridge” mode for any application (4 Ohms per channel/8 Ohms
bridge for GPS 3500). Operation at loads of 4 Ohms per channel or 8 Ohms “bridge” mode is more
desirable for sustained operation applications due to the fact that the amplifier will run much cooler at this
loading. Operation above 4 Ohms per channel and even open circuit conditions can always be considered
safe.

Power requirements for the GPS Series amplifiers are rated at “typical” music conditions. The maximum
power current draw rating is limited by the amplifier’s circuit brea er. Consult the specification sheet for
the current that each amplifier will demand. AC mains voltage must be the same as that indicated on the

For your safety, we have incorporated a removable 3-wire line (mains) cable with proper grounding
facilities. It is not advisable to remove the ground contact under any circumstances. If it is necessary to use
the equipment without proper grounding facilities, suitable grounding adapters should be used. Less noise
and greatly reduced shoc hazard exists when the unit is operated with the proper grounded receptacles.
NOTE: Always turn off the amplifier before making audio connections. As an extra precaution, have the

Cooling air is drawn by synchronized, variable-speed fans mounted on the bac panel, and exhausts
through slots on the front panel. The fans will remain at low speed until internal operating temperature
rises above 450C. Ma e sure that there is enough space around the bac of the amplifier to allow air to
enter. The normal operating temperature is 550C. This is a very cool temperature when compared to most
amplifier standards. What this means to you is a noticeable increase in product life. On the GPS 900 and
1500 models, the fans will turn on simultaneously when temperature activated.

These GPS Series amplifiers use a forced-air cooling system to maintain a low, even operating temperature.
Cooling air is drawn by continuously variable speed fans mounted on the bac panel, and exhausts through
slots on the front panel. The fan will remain inactive until internal operating temperature rises above 450C.
Ma e sure that there is enough space around the bac of the amplifier to allow air to enter. The normal
operating temperature is 550C. This is a very cool temperature when compared to most amplifier standards.
What this means to you is a noticeable increase in product life.
NNOOTTEE::If the amplifier is rac -mounted, do not use doors or covers on the front or bac while the unit is in
operation. Whatever type of rac you are using, ma e sure that heated air can escape freely, and that there
is no resistance to the inta e of cool air through the bac grill. Inta e and exhaust air must flow without
resistance.

The input connector accepts balanced and unbalanced audio signals. For use with an unbalanced source,
tie the inverting (-) input to ground by installing a jumper to the signal ground connection. If the inverting
input is left floating, a 6 dB loss in gain will result.
SSIIGGNNAALL MMOODDEE CCOONNFFIIGGUURRAATTIIOONN
GPS Series amplifiers are configured for two-channel (stereo) or bridged mode operation at the input
connectors and via Mode Switch. To send the same signal to both channels, connect the input signal to
Channel A via the input connector. Run a jumper from the Thru jac of Channel A to the input of Channel B.
Both channels then share Channel A’s input signal, but will operate independently. Spea ers are connected
as in two-channel (stereo) mode.
Bridged mode converts the amplifier into a single-channel unit with a power rating equal to the sum of
both channels’ power ratings, and at a load rating of twice that of the single-channel rating. In bridged
mode, the channels operate at opposite polarity of each other so that one channel “pushes” and the other
“pulls” equally. Signal is connected to the Channel A Input connector. The spea ers are connected only to
the designated “+” output terminals. Never ground either side of the spea er cable when the amplifier is in
bridged mode, as both sides are “hot”. For GPS Series amplifiers, the minimum nominal load impedance in
bridged mode is 4 Ohms (8 Ohms for GPS 3500); this is the equivalent of driving both channels at 2 Ohms
(4 Ohms for GPS 3500).

Spea ers are connected using the output connectors on the rear of your amplifier. Ma e sure the amplifier
is turned off before you change any output connections. Refer to the diagram on page 14 to view the wiring
configuration of the Spea on connectors if your model utilizes them. Consult the Wire Gauge Chart on page
14 to find a suitable wire gauge and minimize losses of power in the spea er cables. Also, ma e sure that
the load impedance is not lower than that rated for the amplifier.
PPrrootteeccttiioonn FFeeaattuurreess
The GPS Series incorporates protection features derived from Peavey’s extensive experience with reliability.
The amplifiers are ruggedly built from high quality components and feature comprehensive protection cir-
cuits to protect your amplifier from those “real world” occurrences.
DDDDTT
At the amplifier’s full power, or clipping point, the channel gain will automatically be reduced, guarding the
loudspea ers against damaging high power and continuous square waves that would otherwise be pro-
duced. This is indicated by illumination of the DDT LED. Operation is virtually transparent in use and full
signal bandwidth is maintained. However, if you have a GPS 900 or 1500 and choose to defeat the DDT
compression function, this will not apply and clipping may occur.
LLooaadd FFaauulltt CCoorrrreeccttiioonn™™
LFC™ (Load Fault Correction™) is an innovative circuit that will instantaneously reduce channel gain to allow
the amplifier to operate at a safe level into an abnormal load. Moderate activation of LFC is inaudible in
normal use. In addition, if extreme low impedance or a short circuit is encountered during high signal level
conditions, the amplifier’s output relay will open.
IInniittiiaalliizzaattiioonn PPrrootteeccttiioonn™™((IIPP™™))
IP™operates every time the amplifier is turned on, or after a protect condition. During turn-on, the amplifier
goes into protect mode and leaves the spea er load disconnected until the amplifier determines that the
operating status is normal. The IP™circuit attenuates the signal during the initial turn-on or protect opera-
tion. After relay release, channel gain gradually increases to the attenuator setting to avoid unnecessary
stress on the loudspea ers.
TThheerrmmaall PPrrootteeccttiioonn
If the heatsin temperature or power transformer reaches an abnormally high temperature, the amplifier
will protect itself by disconnecting the spea er load until the amplifier returns to a normal temperature.
During this time, the Power LEDs will not illuminate for that particular channel, and the cooling fan(s) will
operate at maximum speed.
SShhoorrtt CCiirrccuuiitt
If an output is shorted, the LFC™, spea er relay and thermal circuits will automatically protect the amplifier.
The LFC™circuit senses the short circuit as an abnormal load condition and reduces the channel gain to a
safe level for the load. In extreme or severe conditions, the spea er relays will disconnect the load and ini-
tiate a power-on start-up sequence.
DDCC VVoollttaaggee PPrrootteeccttiioonn
If an amplifier channel detects DC voltage or subsonic signals at its output terminals, the spea er relay will
immediately open to prevent loudspea er damage.
