Other Controls
Crossover Switch
If you choose to bypass the internal crossover and use an external crossover, such as those located in most
modern receivers and processors, then you will need to ne tune the system based on the adjustments
provided by the manufacturer of your electronics in conjunction with the Level and Phase controls on the
MODEL 500. Note, the Level and Phase adjustments on the MODEL 500 are not bypassed and will still
function as indicated above.
To bypass the internal crossover, move the Crossover switch (6) to the Bypass position. The subwoofer will
now pass signals up to 300Hz.
Auto Power Mode Switch
The same circuit also places the MODEL 500 into standby mode when no signal has been detected for a
period of approximately 10 minutes. This signal sensing circuit can be bypassed by switching the Auto switch
(2) to the OFF position if it is preferable to control the MODEL 500’s power with a remotely operated power
