During normal conditions, your new subwoofer may be left on
continuously without any problems. The unit is equipped with a signal-
sensing turn on/ off that will automatically turn on the unit when a signal
is present at the inputs and turn off the unit after several minutes when
there is no longer any signal at the inputs. If you plan to leave the
subwoofer unused for an extended period of time, we recommend that
you turn off the master power switch on the rear panel.
PROTECTION CIRCUITRY
Your new subwoofer is equipped with special protection circuitry to
provide maximum performance with greatest reliability.
The unit is protected against:
1) Overdriving the speaker or amplifier
2) Overheating the amplifier
3) Excessive drop in power line voltage
The first type of protection circuitry which prevents overdriving of the
speaker or amplifier operates constantly without being audible under
most situations. In some extreme situations (sustained high output levels
such as pro sound usage), the unit may shut down momentarily. This
indicates the thermal or under-voltage protection circuitry has engaged.
If this should happen, you should reduce the volume setting or shut the
unit off until normal operating conditions return. You may also want to
plug the unit into a different wall outlet, as dropping power line voltage
will be most noticeable under strenuous conditions and may result in the
unit shutting down intermittently.
