SR835 Crossover
INTRODUCTION
Congratulations, and thank you for your purchase of the DOD SR835 Crossover.
The SR835 is a high quality sound reinforcement tool capable of providing your
PA or sound reinforcement system with speaker protection and the increased
clarity and efficiency that results when bi-amping, or tri-amping.
So what is bi-amping, and tri-amping? A bi-amped system means you are using
two power amps to drive separate ranges of frequencies.The crossover is doing
a two way split, separating the high frequencies from the low frequencies and
directing the two ranges to different outputs. One amp receives the low fre-
quencies, and powers your bass speakers.The other power amp receives the high
frequencies and powering the horns, or high frequency speakers.Tri-amping uses
three power amps because the crossover is separating the lows, mids, and highs
from each other.
The SR835 is capable of 2 way splits(bi-amp) in stereo, and three way splits (tri-
amp) in mono.The SR835 uses Butterworth state variable filters providing an 18
dB per octave slope for the selected crossover frequency. This means that if you
have selected the crossover frequency to be 500Hz for instance, the signal com-
ing out of the the low frequency output will loose 18 dB of signal for every
octave above 500 Hz. Likewise, the high frequency output will lose 18 dB of sig-
nal for every octave below 500 Hz.
This Owner’s Manual is your guide to understanding how to get the most out of
