180 Hz cut and boost, and 15 kHz cut and boost).
Designed primarily to help compensate for speaker
deficiencies, eliminate distortion, and boost range.
Input is independently adjustable from 30 mV to
3V RMS. Includes a high-quality volume control
Powered by “phantom power” provided by any
ORION amplifier or an ORION PPS 100 Phantom
Power Supply.
600 EQM EQUALIZER MODULE
Audiophile grade equalization for well set-up car
audio systems. Features high quality, troublefree

uously adjustable, 12 dB per octave, 2-way crossover.
Designed for use in multi-amplifier systems with some
amplifiers dedicated to the low frequencies and some
amplifiers dedicated to the high and midrange fre¬
quencies. Independent adjustment of low pass and
high pass frequencies from 50 Hz to 5 kHz. Extremely
versatile—capable of driving up to 20 amplifiers.
“Phantom power” is supplied by any ORION ampli¬
fier or by an ORION PPS 100 Phantom Power Supply.
300 CRX 3-WAY ACTIVE CROSSOVER
The ORION 300 CRX is a versatile 12 dB per octave
3-way crossover. Designed for use in multi-amplifier
systems with some amplifiers dedicated to only the
high frequencies, some amplifiers dedicated to only
the midrange frequencies, and some amplifiers dedi¬
cated to only the low frequencies. Independently
adjustable for each frequency range. “Phantom
power” is supplied by any ORION amplifier or by
an ORION PPS 100 Phantom Power Supply.
400 BDG
BRIDGING MODULE
The ORION 400 BDG Bridging Module is used to
convert two stereo channels to mono to double the
output power. Generally used to convert the lows
(bass) to mono while leaving the midranges and highs
in stereo. Four modes of operation:
1. Mixed mono output. 2. Summed mono output.
3. Bridged stereo right. 4. Bridged stero left.
Can be used in single or multi-amplifier systems.
Powered by “phantom power” provided by any
ORION amplifier or an ORION PPS 100 Phantom
Power Supply.
500 PMQ PARAMETRIC EQUALIZER
Outstanding flexibility. Allows you to change the
frequency of boost and cut. The ORION 500 PMQ
Parametric Equalizer features five dual controls -
outer knob for selecting the frequency band, and
an inner knob for controlling boost or cut for each
band. Frequency bands are 20 to 60 Hz, 40 to 120
Hz, 250 to 750 Hz, 2.5 to 7.5 kHz, and 5 to 15 kHz.
Boost and cut for each frequency band is 10 dB up
or 10 dB down. The EQ curve is fixed. Includes a
high-quality volume control. Gain adjustment is
30 mV to 3V RMS. Powered by “phantom power”.
