25Hz Level Knobs
The 25Hz Level knob sig-
nificantly adjusts the level
between 20 and 30Hz by
±10dB. This is an area where
peaks and dips of different
amplitudes often manifest in
real environments. This set-
ting is dependent on room
size and construction, system
configuration and personal
preference
Bicolor Amplifier Status Light
This multi-color LED indi-
cates the current status of the
amplified PoweredForce™
woofer system.
No color: No power. The
Summit X is not plugged in.
Blue: Play mode. This indicates
the Summit X detects an audio
signal and is operating normally.
Red: Standby mode. This
indicates the Summit X has
detected no audio signal for
approximately 15 minutes.
Flashing Red: Safe mode.
This indicates if the Summit
X’s temperature has exceed-
ed nominal operating range
or that another error has
occured. Normal operation
will resume when available.
This can also occur after initial
plug in or while transitioning
to standby mode. This is nor-
mal and will clear upon music
signal or after entering stand-
by mode.

size and construction, system
configuration and personal
preference.

PoweredForce™ woofers, and
must be connected to an AC
power source.

phragm charge status.
No color: The circuit has
turned off due to lack of signal
