SR Crossover

NSTALLATION
** Be sure to begin installation with all AC power to your sound system
turned off.
Install the crossover in a rack using the provided rack screws and washers.
Route the AC power cord away from audio lines and plug into a convenient
outlet. Connect audio lines to the crossover using the appropriate input jacks
to channels 1 and 2 (for stereo operation) or to channel 1 (for mono
operation). Connect the appropriate output jacks for stereo 3-way, mono 4-
way operation (SR834 only), or stereo 2-way, mono 3-way (SR823). The rear
panel is clearly marked for proper connection. Follow the top labels for stereo
connection or the bottom labels for mono connection.
All inputs and outputs are balanced. Use XLR type male plugs for inputs and
female plugs for outputs. For balanced operation using 1/4" phone plug
connectors, use only tip-ring-sleeve (stereo) jacks. For unbalanced operation
using 1/4" phone plug connectors, use only tip-sleeve (mono) jacks.
FOR BALANCED CONNECTION:
Wire XLR connections as follows:
Pin 2: high
Pin 3: low
Pin 1: ground or common
FOR UNBALANCED AMPLIFIER CONNECTION:
To make an unbalanced connection to the unit's XLR connectors, wire the line
connectors as follows:
Pin 2: high
Pin 3: NO CONNECTION
Pin 1: ground
Use tip-sleeve 1/4" phone plug connectors for connection to the amplifiers,
wired as follows:
tip: high
sleeve: ground
Once the crossover is installed, adjusted, and tested, an optional security
panel may be secured to the front panel of the unit to prevent tampering.
