SR835 Crossover
TRI-AMP APPLICATIONS
For tri amp applications, the SR835 must be set to the Mono mode. The Mono
mode configures the SR835 as one channels providing a three way split. If you
are running your sound system in stereo, you would need two SR835s in order
to run a Stereo tri amp configuration. The following procedure outlines the
steps for running a tri amped system. Begin with the power turned off.
1. Make sure the Mono Mode switch on the front panel of the SR835 is in the
“in” position. The LED next to this switch should be on.
2. Turn the Channel 1 Gain knob to 0 (fully counterclockwise).
3. Set the Channel 1 Low and the Channel 2 Mid and High Level knobs to - infin
ity (fully counterclockwise).
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 used to drive the bass speak-
ers.
6. Connect from the Channel 2 Mid Bal (for balanced lines), or Mid Unbal (for
unbalanced lines) to the input of the power amp used to drive the mid range
speakers.
7. Connect from the Channel 2 High Bal (for balanced lines), or High Unbal (for
unbalanced lines) to the input of the power amp used to drive the horns or
high frequency speakers.
8. Consult the manufacturers specifications for your speakers to determine the
proper crossover frequency for your mid range speakers. This will usually be
listed as the frequency response or frequency range. Set the Channel 1
Frequency knob slightly higher than the lowest specified frequency for the mid
range speakers.
9. Consult the manufacturers specifications for your speakers to determine the
proper crossover frequency for your high frequency speakers or horns. This
will usually be listed as the frequency response or frequency range. Set the
Channel 2 Frequency knob slightly higher than the lowest specified frequen-
cy.
Note: The markings on the SR835 Frequency knobs 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..
10. Apply power to your mixer, then to the SR835, and finally to your power
amps.
