UNPACKING
Inspect the amplifier during unpacking. If you find any damage, notify your dealer immediately. Only
the consignee may institute a claim with the carrier for damage incurred during shipping. Be sure to
save the carton and all packing materials. Should you ever need to ship the unit back to Peavey
Electronics, one of its service centers, or the dealer, use only the original factory packing.
AMPLIFIER CONFIGURATION
Peavey Electronics IA Series amplifiers accommodate input and control modules. The amplifiers are
factory-configured with a single basic input module. The amplifier may be factory or dealer equipped
with optional input modules, communication modules, combination modules, and AC mains and
speaker load voltage and current consumption modules. The input and communication module(s)
are accessible on the back panel of the amplifier. The voltage and current consumption module is
factory-installed only and is internal. Sequential remote turn-on capability is a standard feature and
is enhanced when under computer control.
INSTALLATION AND MOUNTING
IA Series amplifiers are 2- and 3-rack-space units of 15 3/4" (400mm) depth that mount in a standard 19-inch rack. On all amplifiers, four front panel mounting holes are provided. Rear mounting
ears are also provided on all amplifiers for additional support. Distance from the back of the front
rack ear to the center of the rear mounting ear holes is 15 9/16" (395mm).
TO SET UP THE AMPLIFIER FOR BASIC USAGE:
1. Rack mount the amplifier in the location where it is to be used, remembering to allow for
adequate access and cooling space. For more information, see the sections on

INPUT AND COMMUNICATION MODULES
The back panels of IA Series amplifiers provide a location to accept plug-in modules. Your amplifier
may have been factory-configured with optional module(s). In this case, information on the relevant
module(s) will be enclosed in the amplifier box, or in a separate binder. If all required information is
not included, please call the Peavey Architectural Acoustics Customer Service department or your
local Architectural Acoustics representative.
1. INPUT MODULE
The IA Series comes standard with a basic input module which has plugable input connectors
and individual channel rotary attenuators. Your amplifier may have been factory-configured
with optional modules. All input modules have internal voltage gain/input sensitivity jumpers
that are factory-set for an overall amplifier gain of 40. Connections at the input connector permit the audio signal ground to be connected or lifted from the chassis ground. See the sec
tions on
Input Module Connections
and
Removing or Replacing a Module
for more
information.
2. OUTPUT BARRIER STRIP
A barrier strip is provided for connection of loudspeakers with bare wire or spade lug connectors. This barrier strip can accommodate up to two 10 gauge wires per terminal.
3. COMMUNICATIONS BAY
A blank panel comes standard with this amplifier. Your amplifier may have been factoryconfigured with an optional module. This optional module may be a singlecommunications
module or a dual module which includes signal input and processing functions. See the
section on
Removing or Replacing a Module
4. IEC POWER CONNECTOR
A standard IEC power connector is located at the upper left corner of the amplifier back
panel. An AC mains cord having an appropriate AC plug for the intended operating voltage is
included.
5. CIRCUIT BREAKER
A resettable, protective AC circuit breaker is located towards the upper left of the amplifier ’s
back panel. If the breaker has tripped, push it back in to return the amplifier to operating condition. If the breaker continues to trip, the amplifier needs servicing. Do not continue to reset
the breaker as severe internal damage and safety hazards could occur!
6. SEQUENTIAL TURN-ON CONNECTOR
The IA Series comes standard with remote controllable sequential turn-on enabled by setting
the front power switch to “STANDBY”. The amplifier is activated by applying a voltage

between 12 to 24 volts DC to the rear-mounted 4-pin plugable terminal, and connecting the
“ENABLE” terminal to the “24V DC+” terminal. When no voltage is present or the “ENABLE”
connection is opened, the amplifier will switch off. Other IA Series amplifiers can be “daisychained” by connecting all “24V DC+” terminals together, all “COMMON” terminals together,
and connecting the “ENABLE OUT” to the “ENABLE IN” of the next amplifier. A mating con
nector is shipped with the amplifier. This function may be performed under computer control if
equipped with an optional module containing sequential capability. If this optional module is
used, no connections need be made to the plugable terminal.
7. FAN GRILL
A continuously variable speed DC fan supplies cool air to the amplifier. DO NOT BLOCK
THIS INTAKE! The fan operates only when the amplifier heatsinks require cooling.
OPERATION
AC MAINS CIRCUIT SIZE REQUIREMENTS.
Power requirements for the IA Series amplifiers are rated at “idle”, 1/8 power (“typical” music
conditions), 1/3 power, and maximum rated power. The maximum power current draw rating is
limited by the amplifier’s circuit breaker. Consult the specification sheet for the current that
each amplifier will demand. AC mains voltage must be the same as that indicated on the back of the
amplifier. Damage caused by connecting the amplifier to improper AC voltage is not covered by any
warranty.
audio connections. As an extra precaution, have the input attenuator turned down during power-up.
NOTE: Always turn off and disconnect the amplifier from the mains voltage before making
COOLING REQUIREMENTS
IA Series amplifiers use a forced-air cooling system to maintain a low, even operating tempera-
ture. Cooling air is drawn by a continuously variable speed fan mounted on the back panel,
and exhausts through slots on the front panel. The fan will remain inactive until internal operating temperature rises above 45oC. Make sure that there is enough space around the back of the
amplifier to allow air to enter.
NOTE: If the amplifier is rack-mounted, do not use doors or covers on
the front or back without pressurizing the back of the rack. Whatever type of rack you are using,
make sure that heated air can escape freely, and that there is no resistance to the intake of cool air
through the back grill. Intake and exhaust air must flow without resistance.
HIBERNATION
All IA Series amps feature Hibernation™circuitry. Current draw and thermal emissions are at a minimum when the absence of input signal is sensed for more than a minute. Once signal is present, the
amp comes out of Hibernation and instantly restores the amplifier to normal. Current draw specifications while Hibernation is active are included in specifications under “Idle Current Draw.”
THERMAL EMISSIONS
The system installer or designer should specify system cooling needs. Refer to the Specifications
appendix at the back of this manual for specific thermal emissions figures.
INPUT MODULE CONNECTIONS
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.
™
SIGNAL MODE CONFIGURATION
IA Series amplifiers are configured for two-channel (stereo), bridged mode, or parallel mode
operation at the input connector. To send the same signal to both channels (parallel mode), connect
the input signal to Channel Avia the input connector. Run jumpers from the positive and negative
terminals of Channel A’s input connector to the respective terminals of Channel B. Both channels
then share Channel A’s input signal, but will operate independently. Speakers are connected as in
two-channel (stereo) mode.
7
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 input connector with one jumper connecting
the positive (+) terminal of Input Ato the negative (-) terminal of Input B, and another jumper connecting the negative (-) terminal of input Ato the positive (+) terminal of Input B. Both channel attenuators (A&B) are used to control signal level, and both must be at the same level, preferably at 0 dB
attenuation. The speakers are connected only to the designated “+” output terminals. Never ground
either side of the speaker cable when the amplifier is in bridged mode, as both sides are “hot”. If an
output patch panel is used, all connections must be isolated from each other and from the panel. For
IA Series amplifiers, the minimum nominal load impedance in bridged mode is 8 ohms; this is the
equivalent of driving both channels at 4 ohms. Driving loads of less than 8 ohms may activate the
Load Fault Correction circuit and may also cause a thermal protect condition.
operating mode, NEVER connect amplifier outputs together!
LINE CORD (120V Products Only)
For your safety, we have incorporated a 3-wire line (mains) cable with proper grounding facilities. It
is not advisable to remove the ground pin 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 shock hazard exists when the unit is operated with the proper grounded
receptacles.
NOTE:
Regardless of

GAIN SELECT JUMPERS
Input modules have user-settable jumpers to configure Input Gain/Sensitivity. These internal jumpers
are used to set the overall gain of the amplifier. Two positions allow the amplifier to be set for constant gain of x20 (26 dB), or x40 (32 dB). The standard factory setting is for x40. Custom gain configurations can be accommodated. Contact the Peavey Architectural Acoustics Customer Service
department. To change jumper settings, the Input module must first be removed from the amplifier
chassis. This operation is covered in the
Module Removal/Replacement
section.
SPEAKER OUTPUT CONNECTIONS
Speakers are connected using the output barrier strip connectors. Spade lugs, ring tongues or
bare wire may be connected to the output barrier strip elements. The barrier strip can accom-
modate up to two 10 gage wires per terminal. Make sure the amplifier is turned off before you
change any output connections or jumpers. Consult the Wire Gauge Chart to find a suitable wire
gauge to minimize losses of power in the speaker cables. Also, make sure that the load impedance
is not lower than that rated for the amplifier.
AMPLIFIER CONTROL BAY
IA Series amplifiers come standard with a blank panel fixed over the top half of the module bay. If
the amplifier is equipped with an optional module, information on the relevant module will be
enclosed in the amplifier box, or in a separate binder. If required information is not included, please
call Peavey Architectural Acoustics Customer Service.
MODULE REMOVAL
Removable modules contain static-sensitive devices; handle modules at static-safe work stations!
SITUATIONS REQUIRING MODULE REMOVAL
Only jumper setting changes or module upgrades require modules to be removed from the amplifier.
Contact Peavey Architectural Acoustics Customer Service for full details on module removal. Do not
remove the top cover! Dangerous voltages exist inside, and only a Peavey Electronics-authorized technician should remove the top cover! The amplifier must be switched off and the mains
plug removed from the supply before module removal operation is undertaken.
REMOVING OR REPLACING A MODULE
The amplifier must be switched off and unplugged from the mains supply before this operation is
undertaken. Remove the Phillips pan head screws that secure the module(s) to the chassis.
Modules are connected electrically to the amplifier via multi-pin ribbon cables. Unplugging the module from the ribbon cable connectors frees the module for removal. To insert the same or another
module, simply reverse this procedure, making sure that both ends of any ribbon cable connectors
are properly and securely seated.
9
THE AC MAINS AND SPEAKER LOAD MODULE IS NOT REMOVABLE. DO NOT ATTEMPT TO
REPLACE OR REMOVE IT!
This module can only be serviced by a Peavey Electronics-authorized technician. Please consult your dealer or Peavey Electronics representative for assistance. User-inflicted damage to
this module will invalidate your warranty.
SIGNAL GROUND CONNECTION
Connections at the input connector permit the audio signal ground to be connected or lifted from the
chassis ground. Whenever possible, the shield of the signal source connecting cable should connect
to the chassis ground. In some cases, however, particularly if an amplifier is being installed in an
existing system, this may result in a ground loop. If this happens, connect the shield to the signal
ground only. The chassis ground also connects to the AC ground internally. If the cable shield is
connected to the signal ground only, it will be clamped to +/- 0.6V above or below chassis/AC
ground.
PROTECTION FEATURES
The IA 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 circuits to protect your amplifier from those “real world” occurrences.
CLIP LIMITING
At the amplifier’s full power, or clipping point, the channel gain will automatically be reduced, guarding the loudspeakers against damaging high power and continuous square waves that would otherwise be produced. This is indicated by illumination of the Clip LED. Normal program transients will
not trigger Clip Limiting; only steady or excessive clipping will. Operation is virtually transparent in
use and full signal bandwidth is maintained.
LOAD FAULT CORRECTION
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. This is indicated by illumination of the LFC LED. 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.
INITIALIZATION PROTECTION™(IP™)
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 speaker 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 operation. After relay release, channel gain gradually increases to the
attenuator setting to avoid unnecessary stress on the loudspeakers.
THERMAL PROTECTION
If the heatsink temperature or power transformer reaches an abnormally high temperature, the
amplifier will protect itself by disconnecting the speaker load until the amplifier returns to a normal
temperature. During this time, the Protect LED will illuminate, and the cooling fan will operate at
maximum speed.
SHORT CIRCUIT
If an output is shorted, the LFC™, speaker 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 speaker relays will
disconnect the load and initiate a power-on start-up sequence.
™
DC VOLTAGE PROTECTION
If an amplifier channel detects DC voltage or subsonic signals at its output terminals, the speaker
relay will immediately open to prevent loudspeaker damage. The Protect LEDs will light.
10
SEQUENTIAL TURN-ON/TURN-OFF
The IA Series comes standard with remote sequential turn-on for applications not under computer
control. The amplifier front power switch is set to “STANDBY”. An external Direct Plug-In Power
Supply Unit providing a nominal voltage between 12 to 24 volts DC must be applied to the rearmounted
4-pin plugable terminal. The “ENABLE OUT” is connected to the “ENABLE IN” of the next amplifier.
IA Series amplifiers are bussed or “daisy-chained” together in parallel and connected to the DC supply by connecting all “24V DC+” terminals together and all “COMMON” terminals together. The first
amplifier in the chain requires an SPST closure between its “ENABLE IN” terminal and “24V DC+”
terminal to initiate the power turn-on sequence and keep the amplifiers in the chain powered on.
This function may be performed under computer control if equipped with an optional module containing sequential capability. If this optional module is used, no connections need be made to the
plugable terminal.
