Fine Tuning the 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 fine tune the system based on the adjustments
provided by the manufacture of your electronics in conjunction with the Level and Phase controls on the
P-1200. Note, the Level and Phase adjustments on the P-1200 are not bypassed and will still function as
indicated above.
To bypass the internal crossover, move the Crossover switch to the Bypass position. The subwoofer will
now pass signals up to approximately 300Hz.
Auto Power Mode Switch
The P-1200 contains a circuit that automatically powers up the amplifier when a signal is detected. The
same circuit also places the P-1200 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 to
the OFF position if it is preferable to control the P-1200’s power with a remotely operated power source.
