When operating the SP1G 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  
SP1G is to have it set to SP2  
mode and reverse the polarity of the  
high-frequency driver. This will give  
the best possible sonic and direc-  
tional performance from the SP1G  
without spending hundreds of  
dollars for a fully programmable  
digital crossover.

ARCHITECTURAL AND  
ENGINEERING SPECIFICATIONS  
The loudspeaker system shall  
have an operating bandwidth of  
50 Hz to 19 kHz. The nominal  
output level shall be 99 dB when  
measured at a distance of one  
meter with an input of one watt.  
The nominal impedance shall be  
8 ohms. The maximum continuous  
power handling shall be 450 watts,  
maximum program power of  
900 watts and a peak power input  
of at least 1,800 watts, with a  
minimum amplifier headroom of  
3 dB. The nominal radiation  
geometry shall be 77 degrees in the  
horizontal plane and 63 degrees in  
the vertical plane. The outside  
dimensions shall be 33.75 inches  
high by 19.0 inches wide by  
20 inches deep. The weight shall  
be 95 pounds. The loudspeaker  
system shall be a Peavey model

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 SP1G 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  
SP1G 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
