When operating the SP™ 1G in
bi-amp mode with an active cross-
over, the CS® X1 input/crossover
module for the CS® 800S is
recommended. This crossover
is designed specifically for this type
of loudspeaker. It may be obtained
as an add-on feature to the
CS 800S at a modest cost. The
proper configuration for this cross-
over module when using it with the
SP™ 1G is to have it set to SP™ 2
mode and reverse the polarity of the
high-frequency driver. This will give
the best possible sonic and direc-
tional performance from the SP™ 1G
without spending hundreds of
dollars for a fully programmable
digital crossover.

POWER HANDLING
There are many different
approaches to power handling
ratings. Peavey Electronics rates
this unit’s system power handling
using a modified form of the AES
Standard 2-1984. It utilizes audio
band limited (20 Hz to 20 kHz) pink
noise with peaks over four times the
RMS level. This strenuous test
signal assures the user that every
portion of this system can withstand
today’s high technology music. The
test signal contains large amounts
of very low-frequency energy,
effectively simulating the frequency
content of live music situations.
The full measure of high
FREQUENCY RESPONSE
This measurement is useful in
determining how accurately a
given unit reproduces an input
signal. The frequency response
of the SP™ 1G is measured at a
distance of 1 meter using a 2.8 volt
swept-sine input signal. As shown in
Figure 1, the selected drivers in the
SP™ 1G combine to give a smooth
frequency response from 50 Hz to
19.0 kHz.
THREE PLUS TWO YEAR
LIMITED WARRANTY
frequencies in the test signal allow
for exposure of the speaker system
to synthesized tones that may
extend beyond audibility. This rating
is contingent on having a minimum
of 3 dB of amplifier headroom
