INPUT SCREW TERMINALS (7)
Provides an electronically balanced input, nominally 100 mV to 1 volt (see Sensitivity Switch). For
unbalanced inputs, use the (+) and (-) terminals.
24 V DC OUTPUT TERMINALS (8)
Provides connection for a low current (20 mA) 24 V DC output for powering low current external add-
on equipment.
SENSITIVITY SWITCH (9)
Switches the input sensitivity from 100 mV to 1 volt.
OUTPUTS (10)
A direct output, as well as several isolated transformer outputs, are provided to allow the proper inter-
face between the amplifier and the speaker system. The direct output allows direct connection to a 4
ohm speaker system. To use this output, disconnect the jumper between the 4 ohm terminal and the
XFMR terminal. Connect the speaker (or speakers) from the GND terminal to the 4 ohm terminal.
Also provided are 8 ohm, 25 volt, and 70 volt balanced outputs. To use these outputs, the jumper be-
tween 4 ohm and XFMR must be installed. For 8 ohm speaker systems, connect between the COM
terminal and the 8 ohm terminal. For "distributed" speaker systems, 25 volt and 70 volt outputs are
provided. The connection for distributed systems is between the COM terminal and either the 25 volt or
70 volt terminals, depending on the required system voltage.
One more output is provided on the IPA Series amplifiers. This is a balanced, transformer-isolated line
level output. This output is provided for direct connection to "music on hold" systems, booster power
amplifiers, etc. This output is designed to deliver 1 V RMS into a 600 ohm load. See Figures 2 through 5
for possible output connections.
AC OUTLET (UNSWITCHED) (11)
Provides AC power for auxiliary equipment with power consumption — 300 watts maximum.
FUSE (12)
The fuse is located within the cap of the fuseholder. If the fuse should fail, IT MUST BE REPLACED
WITH THE SAME TYPE AND VALUE IN ORDER TO AVOID DAMAGE TO THE EQUIPMENT
AND TO PREVENT VOIDING THE WARRANTY. If the amp repeatedly blows fuses, it should be
taken to a qualified service center for repair.
