Signal-Processing Modules
When signal-processing output modules are
installed into the Power Vector's last
two module bays, they automatically insert
themselves into the mix bus signal path lead-
ing to the power amplifier stage. When two of
these output modules are installed, their ef-
fects are cascaded with the second to last
bay's module processing the signal first and
then passing it to the module in the last bay.
Two benefits are gained by this innovation: (1)
the effects insert jacks are still available for
use by external processing equipment, (2) the
signal-processing output modules act on the
raw mix bus signal before any other user con-
trols, like master volume, bass, and treble.
This then ensures that signal level dependent
processors, such as the CMP1R Compressor/
Limiter and the ANS1R Ambient Noise
Sensor modules, perform as intended regard-
less of front panel master control changes.
Remote Volume Control
The master volume control is motorized.
By using a motor to physically move the con-
trol knob, a new level of remote control
adjustability is achieved.
Regardless of where the master volume con-
trol is set on the amplifier, the remote can
move it up or down. Since the remote control
signal is now the drive signal to the motor,
noise on the remote control leads cannot mix
in with the amplifier signals. This gives the
Power Vector a fully functional and clean way
of remotely controlling overall system level.
Traditionally, remote volume control was ac-
complished by having the remote control
vary an analog control signal to an opto-
resistor in the amplifier. This opto-resistor
would further attenuate the signal level in the
amplifier, based on the remote control setting.
This approach has two drawbacks: (1) the
maximum volume that can be achieved by
changing the remote control was limited by
the master volume control setting on the
amplifier, or vice-versa depending on how
the amplifier was designed, the remote
could lower volume, but could not further in-
crease it; (2) the control signal, because it is
analog, is vulnerable to noise. If a 60 Hz
hum was picked up by the long remote
volume leads, it could cause the opto-
resistor to modulate the volume level at the
hum frequency.

Power Vector Modular Amplifiers
V35, V60, V100, V150, V250
Bogen's Power Vector modular input amplifier series offers a wide range of
power levels from which to choose, with five models ranging from 35W to 250W.
The amplifiers are designed to work with both high- (70V/25V) and low- (4/8-ohm)
impedance speaker systems. Each model includes eight module bays for input
modules and allows up to four levels of priority between modules. Two module bays
are also capable of accepting signal-processing output modules. Each input channel
has an associated signal/clip LED for signal status. An 11-segment LED output meter
monitors output signal level, which can be controlled by the Remote Volume
Control Panel (RVCP, sold separately). Modules required, but sold separately.
