Module Removal - Peavey IA 200 Owner's Manual

Bridged Mode Diagram
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 con-
stant gain of x20 (26 dB), or x40 (32 dB). The standard factory setting is for x40. Custom gain con-
figurations 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-autho-
rized 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 mod-
ule 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.
