OPERATIONAL OVERVIEW
3 Installation
FITTING OF FEET
Screw the four cones into the inserts on the base of the cabinet. Spikes and lock nuts are provided to
provide stability when used on a carpet. For use on a wooden floor, the spikes should be inverted.
CONNECTING TO YOUR SYSTEM
For 2 channel stereo use, if your preamplifier has a spare set of outputs, connect left and right to the
subwoofer L and R phono inputs using screened cable. Alternatively for AV use, take the subwoofer
output from your AV processor, and plug into either LINE IN phono socket.
Users with balanced systems may make use of the XLR inputs. With this option, a LINE OUT facility is
provided, to feed the main speaker pair. This can be selected by the adjacent switch to be either a
DIRECT feed, or provide an 80Hz HIPASS function. The latter setting is recommended for smaller main
speakers.
SETTING UP
} Ensure the main POWER switch is in the OFF position.
} You can operate these subwoofers in two modes, AUTO and ON continuously, using the
switch provided. In AUTO, the unit remains OFF until an input signal is detected.
} Status is confirmed by the power light, which glows red in AUTO standby, but is
otherwise green.
AV SYSTEMS:
Firstly set GAIN (volume) control to MIN, and LFE MODE switch to ON. This will bypass the unit’s
internal crossover, with this function now provided for within the AV processor. The XOVER FREQ.
Control will no longer be functional. Set the PHASE control to 0
0
.
The LED will turn green when switched ON, or when a signal is detected in AUTO mode.
Set the LF XTENSION control to mid position and play some music or other material through the
system and slowly increase the input level control until roughly the correct amount of bass is present.
If this does not prove possible, rotate the PHASE control clockwise, which with some speakers and
rooms will give increased bass output. Moving the LF XTENSION control anticlockwise towards the
MUSIC position will give a deeper more extended bass, while moving it clockwise towards the
THEATRE position will increase the impact of movie sound effects. Fine adjustment of the controls
will take a little time using a range of different programme material.
Remember that the object of a subwoofer is to enhance the output of your main speakers, not
overpower it.
