Orion 280gx User Manual

"Phantom Power (+15V & -15V) is supplied to all
ORION accessory modules by the amplifier through
the DIN cable. (When ORION amplifiers are not
used, the ORION PPS 100 Phantom Power Sup¬
ply is required.)

This is a 3-amp system using a
300 CRX 3-Way Active Cross¬
over. The 300 CRX makes it
possible to use separate ampli¬
fiers for the tweeters, midrange
speakers, and subwoofers.
Less power is required to drive
the high frequencies to the tweet¬
ers than that required for midrange
and low frequencies, so this dia¬
gram shows a 240gx (40 watts
per channel) amplifier being
used. A GS-100 (50 watts per
channel) could also be used.
The midrange and subwoofer
amplifiers could be selected
according to your output power
requirements and space avail¬
ability. (If you decide on amp¬
lifiers larger than 280gx's, you
will probably have to add an
additional battery. Refer to page
27.)

The high frequency output of the 300 CRX is an adjustable high pass filter. A common
adjustment would be to pass all frequencies 4000 Hz and above to the tweeters. The mid¬
range output is a bandpass filter with separate controls for adjusting the low end and the
high end. A common adjustment might be to pass all frequencies between 100 Hz and
4100 Hz, but the settings are dependent on the settings of the high and low frequency
outputs. There should be a certain amount of overlapping. The low frequency output
is an adjustable low pass filter. A common adjustment would be to pass all frequencies
below 180 Hz. The actual settings of the frequencies depend on what sounds best in your
system.
If you intend to use this system, we highly recommend that you double the output of
your subwoofer amplifier by adding a 400 BDG Bridging Module as shown in figure 9.
