CONTROLS
CROSSOVER
The CROSSOVER control is variable from 50Hz to
180Hz. In simple terms, the subwoofer will play all
frequencies below the CROSSOVER setting.
LEVEL
The LEVEL control sets the volume of the subwoofer
in relation to the main speakers. Once set, volume
will climb and decrease along with your main system
volume.
PHASE
The PHASE control allows you to adjust the phase
of the subwoofer relative to the main speakers. This
helps when positioning the subwoofer - in general, if
the subwoofer is in front of the listening position have
the PHASE set to 0º. If the subwoofer is behind the
listening position, then set the PHASE to 180º.
POWER SWITCH
Set to either OFF, AUTO or ON. When set to AUTO,
the RoomSub will automatically detect a signal from
the source amplifier and, in turn, will power up the
subwoofer. It will also return to its standby mode
automatically when the source is no longer detected.
AC SELECTOR
This should already be set to the voltage used in your
country. It can be adjusted should you wish to a use
this product in a country where a different AC voltage
is used. Please note that the internal fuse should be
changed to suit the new AC voltage.

CONNECTIONS
LINE IN/OUT
This is used to connect your RoomSub to your
amplifier using a coaxial (RCA) cable. Connect the
subwoofer pre-out or LFE (SUBWOOFER) output on
your amplifier to the LINE-IN on the subwoofer.
POWER CONNECTOR
Plug the AC power cable here, and then into a mains
supply, do this after all other connections have been made.
USB CONNECTOR
This can be used to power external equipment such
as a wireless signal receiver. The USB connector can
output a maximum of 1 amp at 5 volts.
FUSE
The fuse protects RoomSub from abnormal power
conditions. If the subwoofer fails to power, check
this fuse and only replace with the type noted below:
110-120V AC Supply - T4AL/250V fuse
220-240V AC Supply - T2AL/250V fuse
