SR835 Crossover
BI-AMP APPLICATIONS
For bi amp applications, the SR835 must be set to the Stereo mode regardless of
whether you are running in stereo or mono. The Stereo mode configures the
SR835 as two individual channels, each providing a two way split. If you are run-
ning your sound system in stereo, both channels would be used: one for the left,
and one for the right. If you are running in mono, only one of these channels
would be used but the SR835 would still be set to Stereo mode in order to
achieve a two way split. The following procedure outlines the steps for running
a bi-amped system in mono. Begin these steps with the power to the SR835
turned off.
1. Make sure the Mono Mode switch on the front panel of the SR835 is in the
“out” position. The LED next to this switch should be off.
2. Turn the Channel 1 Gain knob to 0 (fully counterclockwise).
3. Set the Channel 1 Low and High Level knobs to - infinity (fully counterclock-
wise clockwise).
4. Connect from the output of the mixer or source signal to the Channel 1 input
of the SR835.
5. Connect from the Channel 1 Low Bal (for balanced lines), or Low Unbal (for
unbalanced lines) to the input of the power amp driving the bass speakers.
6. Connect from the Channel 1 High Bal (for balanced lines), or High Unbal (for
unbalanced lines) to the input of the power amp driving the horns or high fre-
quency speakers.
7. Consult the manufacturers specifications for your speakers to determine the
proper crossover frequency. This will usually be listed as the frequency
response or frequency range of your high frequency speakers or horns. Set
the Channel 1 Frequency knob slightly higher than the lowest specified fre-
quency.
Note: The markings on the SR835 Frequency knob range from 100 Hz. to 1000
Hz..The push button switch to the left of the Frequency knob will multi-
ply these frequencies by 10 extending the range from 1000 Hz. to 10,000
Hz..
8. Apply power to your mixer, then to the SR835, and finally to your power amps.
Begin sending signal through the system. Gradually turn up the High Level first
and confirm correct wiring.Turn up the Low Level to balance the tonality.Adjust
the Gain knob for appropriate signal strength.
Note: This procedure will also apply to Stereo bi-amping. Simply repeat steps2
through 7 for Channel 2.
