Signal Processing
Insert Jacks
Allows external
equipment to be
inserted between
the pre-amp output
and the power
amp input.
Bridging
Connector
Allows system
expansion by
linking multiple
Power Vectors’
mix buses
together.
Remote Volume
Control Terminals
Connect the optional
Remote Volume
Control Panel (RVCP)
to these terminals
to provide remote
operation of the
Master Volume
Control knob.
Mute Control
Terminals
These terminals
make the priority
buses available
externally for
linking Power
Vectors together
into larger systems
or for external
control.
Module Bays
Each of 8 module
bays can accommodate
advanced plug-in input
modules. Bays 7 & 8 also
accept signal-processing
output modules. Up to
4 levels of priority
can be programmed
between modules.
8 Independent Inputs
Each input source is individually
controlled by a corresponding
volume control knob for complete
system customization.
Average/Peak Switch
The Power Vector can register the
average or peak level of the
output signal on the
11-segment LED meter.
Bass & Treble Controls
Select the amount of cut or
boost of bass frequencies
below 100 Hz and treble
frequencies above
10 kHz (bypassable).
Pre-EQ Jack
Output jack provides
unbalanced, buffered output
signal "post" all unit
signal processing, but
"pre" any external signal
processing equipment
connected to the
Insert jacks.
Power Indicator & Switch
An LED indicates whether the
amplifier power status is on or off.
A rocker-type switch applies or
removes power to the amplifier.
Master Volume Control Knob
Controls overall volume level of the mixed
input signals. The control is motorized and
can be adjusted manually or by an optional
remotely mounted control panel.
LED Output Meter
This 11-segment LED
meter monitors the
output signal level of
the power amplifier
or the mixer.
AC Receptacle
Grounded, unswitched
power receptacle
conveniently provides a
maximum 500W capacity
for external equipment.
Speaker Output
Barrier Strip
A 5-position barrier
strip, with clamping
washers, provides
connections for
speaker loads.
Lo-Cut Switch
This slide switch
allows roll off
of frequencies
below 125 Hz
for protecting
horn speakers.
Tone Control
Bypass Switch
This slide switch
allows the effects
of the Front Panel
Bass and Treble
controls to be
bypassed.
Signal/Clip Indicators
A two-color LED indicates the
audio activity for each
of 8 input channels.
Green - The input’s signal is
present on mix bus.
Red - The channel’s input
is being overdriven.
Trans Out/
Direct Out Switch
Amplifier can be used with
70V, 25V, and 8-ohm speaker
systems via its output transformer
or with low-impedance speakers
via direct drive (4Ω min.).
