MAINS IN
AC connection is established via an IEC-
connector. A 10 ft (3 m) long AC cord with
fitting IEC-plug is supplied. Locking IEC
power cords may also be used.
Function
LIMIT
The LED brief blinking indicates the power
amplifier is operated at its limits. Short-term
blinking is not critical because the integrated
limiter keeps distortion under control.
Constant lighting of the LED indicates the
sound is negatively affected. Reducing the
output volume is strongly recommended.
LEVEL
Level control for adjusting the volume of the
subwoofer. The level control affects the
volume of both Channels A and B.
BOOST
The BOOST switch controls the low-
frequency extension of the subwoofer.
NORMAL works best when the subwoofer is
used under normal applications. LOW-END
BOOST provides additional low-frequency
extension and works best for applications
requiring enhanced bass performance.
POLARITY
The POLARITY switch controls the acoustic
polarity of the subwoofer. When using with a
ZxA1 and in most applications, the switch
should always be set to NORMAL. If the bass
output is low when using with other
loudspeaker systems and subwoofers, try
setting the switch to REVERSE POLARITY.
XLR INPUT
XLR input connector to receive the signal
from another speaker or subwoofer.
