RM705 Subwoofer Power Management

With subwoofer power switch set to Auto, power is supposed to switch off 15 minutes after input signal is lost, and it is supposed to come on when a signal is received. My new RM705 does power off automatically, but it does not power on when signal returns and I have to switch it on manually. Any ideas? Thanks.

    sometimes i notice i have to crank the volume louder to get the sub going, it will only turn on when the input signal reaches a certain voltage.

    Try turning the volume adjustment on the subwoofer itself down. Then, turn the subwoofers volume up in the receiver to compensate. This way it should take less receiver volume to turn the subwoofer back on.

    that will do no good, as i stated before the subwoofer automatically turns on when the input signal reaches a certain voltage.

    Exactly. By increasing the volume *coming from* the receiver, you are increasing the signal/voltage level. The position of the volume knob on the sub itself shouldn't have any effect on the input detection circuitry. It will only serve to compensate for the higher signal level coming from the receiver.

    Have you actually tried this and confirmed it didn't work?

    I used to have the same problem with my sub, and the problem was fixed by turning the subs internal gain down, and turning up the sub level in my AVR.

    Thanks all for feedback. Turning the subwoofer volume down and boosting the receiver subwoofer output did the trick. Thanks.
