Peavey IPA 150T - Connectivity Details; Line Input Ports; External Volume Control; Speaker Output Options

LINE INPUTS (5)
The input connections are configured to allow balanced and
unbalanced signals to be connected to the system. See
figures 1 and 2.
EXTERNAL MASTER VOLUME (6)
These terminals allow connection of an external volume con¬
trol. To gain complete control of volume from an external
volume control, the front panel "level” control must be set
to maximum. The external volume control should be con¬
nected as shown in figure 3.
RCA INPUT JACK (7)
The RCA line input is paralleled with other inputs. See figure
4 concerning use of this jack.
1 / 4 " INPUT JACK (8)
The Va” phone input allows balanced operation (RTS).
OUTPUTS (9)
A direct output, as well as several transformer outputs, are
provided to allow the proper interface between the amplifier
and the speaker system. The direct output allows direct con¬
nection to a 4 ohm speaxer 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. 8 ohm, 25 volt and
70 volt balanced outputs are also provided. To use these
outputs, the jumper between 4 ohm and XFMR must be
installed. For 8 ohm speaker systems, connect between the
COM terminal and the 8 ohm terminal. 25V and 70V balanc¬
ed outputs are also provided for "constant voltage” speaker
distribution systems. The connection for distributed systems
is between the COM terminal and either the 25V or 70V ter¬
minals, 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 that
is provided for direct connection to "music on hold”
systems, booster power amplifiers, etc. This output is design¬
ed to deliver IV RMS into a 600 ohm load. See figures 5
through 8 for possible output connections.
INSTALLATION INFORMATION
POWER HANDLING AND GROUNDING:
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 adaptors should be used. Less
noise and greatly reduced shock hazard exists when the
unit is operated with the proper grounded receptacles.
INSTALLING THE RACK-MOUNT EARS
This unit can be rack-mounted with optional rack-mount
kit. To attach the rack-mount ears, simply remove the three
screws already in the front on either side of the unit and
align the ears with the rack-mount flange forward of the unit.
Replace the screws and tighten securely, being careful not
to overtighten. The unit then mounts in a standard 2 space
19" rack. You may find it desirable to remove the rubber
feet from the bottom of the unit in rack-mount installations.
The rack-mount ears may also be used to secure the unit
in a shelf application to deter theft.
RACK-MOUNT RECOMMENDATION
To provide adequate ventilation, leave at least one rack
space between units when multiple amplifiers are mounted
in the same rack.
ARCHITECTURAL & ENGINEERING
SPECIFICATIONS
The power amplifier shall have one
input that has provisions for both
balanced and unbalanced signals.
Connections for the unbalanced input
shall be provided via an (RTS) 1/4“
jack or by barrier strip connections.
Connections for the unbalanced input
shall be provided by the (RTS) 1/4"
jack, the barrier strip connections, and
the RCA phono jack.
Provisions for an external master
volume control shall be made via
barrier strip connections on the back
panel. The unit shall be packaged in a
rugged metal chassis 17" wide by
3 1/2" high by 15 3/4" deep (including
external heatsinks). The unit shall
operate from standard 120 volts AC,
60 Hz power. The power amplifier
shall be capable of delivering 150
watts into 4 ohms and 8 ohms, as well
as providing 25 volt and 70 volt line
outputs. The unit shall be capable of
delivering 40 Hz to 20 kHz rated
power from +0/-1 dB into 4 ohms at
its direct output at 0.5% or less distor¬
tion with system hum and noise at
least 95 dB below rated output. The
unit shall be called the Peavey
Architectural Acoustics Division model
IPA 150T.
