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.
BYPASS/CROSSOVER
Activates the subwoofers built-in bass management, or
bypasses it. If your amplifier has bass control, like an AV
receiver, then set to BYPASS, otherwise set to CROSSOVER.
BASS BOOST
Allows for more convenient bass equalisation, increases bass
volume in relation to the main speakers without adjusting any
other controls.
POWER SWITCH
Set to either OFF, or AUTO ON. When set to AUTO ON, the
TR-3D 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 be preset to your country of use. However you
can adjust this if you move to a country where a different AC
voltage is used. Note that you will also have to change the
internal fuse to suit the AC voltage.

CONNECTIONS
HIGH LEVEL IN/OUT
The HIGH LEVEL IN is used to connect your amplifier
to your subwoofer using speaker cables. You can then
connect a pair of speaker to the HIGH LEVEL OUT. This
will also activate the subwoofers built-in crossover, and
protect the speakers from the lowest frequencies.
LINE IN/OUT
This is used to connect your TR-3D to your amplifier
using a coaxial (RCA) cable. Connect the pre-out or LFE
(SUBWOOFER) output on your amplifier to the LINE IN
on the subwoofer. If required, you can connect the LINE
OUT to your power amplifier.
POWER CONNECTOR
Plug the AC power cable here, and then into a mains
supply, do this after all other connections have been
made. Ensure that the AC SELECTOR is preset to the
correct position for your country.
FUSE
The fuse protects the TR-3D subwoofer from abnormal
power conditions. It’s located under a small cover in the
subwoofer AC power socket. If the subwoofer fails to
power, check this fuse and only replace with the types
noted below :
115V AC Supply - T5A 250V fuse
230V AC Supply - T2.5A 250V fuse
