5. Mains Voltage Selector
Factory preset to suit the voltage of the country of origin. This should not be adjusted.
6. Mains Power Switch
Mains 'rocker switch' providing overall power off and on/ auto. In the on/auto mode, the unit will turn on when an input signal is
sensed or RS232 command and will turn off after 20 minutes (default setting) when the signal is removed (source turned off).
Alternatively, using the 12v trigger (see above) to control the power by turning the source on or off.
7. IEC Mains Input Socket & Fuse Location
The subwoofer is supplied with a three-pin mains input socket for connection to the mains supply. Use ONLY the appropriate IEC mains
lead provided with the product. Also fitted is an external mains fuse. If a fuse blows during operation a spare fuse is provided within the
fuse holder for replacement. If you wish to change the fuse, you can do this by removing the IEC mains lead and carefully levering out the
original fuse from its holder below the IEC mains input socket (7a, opposite). If the fuse blows again it is advisable to seek help from an
authorised service agent. DO NOT attempt to re-fit a further fuse as this could result in serious damage to the amplifier unit.
8. Balanced LFE Input
To be used when connecting to the balanced output on the amplifier. This is the best method of connection when using long
runs of cables (over 10m upto 100m). A balanced connection provides a much better, almost noise free method of connection
over analogue audio type connectors.
9. RCA LFE Input
This input is to be used when connecting the subwoofer to an AV amplifier/ receiver. When using the LFE input, the crossover
function in the menu/ set-up is not used. This is due to the crossover function being controlled by the source to which it is
connected. Input between LFE and Stereo input is switched automatically.
10. RCA Stereo Input
For connection to a 2 channel/ stereo amplifier system. Connection should be provided by a pair of high-quality signal cables from the
pre-out section of an amplifier. Note:- cable lengths should not exceed 10 metres to avoid interference from other electrical appliances.
11. Preset LED's
These indicate the selected preset.
1. Music: Maximum low frequency extension to pick out the fundamental frequencies of every musical instrument.
2. Movie: The same flat response with good sensitivity, but a little more extension to create a balance between the explosive
and atmospheric moments of a good film.
3. Flat: This is the sweet spot between a flat extended response and minimal use of DSP enhancement. A good starting point
to create your own custom EQ profiles from.
4. Impact: Uses the maximum natural efficiency of the drivers for explosive impact.
12. Preset Select Button
This button scrolls through the 4 preset EQ profiles. Refer to page 6. It also wakes the subwoofer from standby without a
signal waking it.
13. Phase Control
This is used to synchronise any delay between the Subwoofer and main speakers. When the subwoofer is in phase with the
main speakers the sound should be full bodied. Sit in a normal listening position whilst adjusting the phase settings. When
set correctly the location of the subwoofer should be almost undetectable. Experimentation is advisable, however it should
be noted that in most cases the phase control should be set to 0 degrees, especially when using a digital AV processor or AV
receiver amplifier. The phase can also be adjusted on the Subwoofer itself.
14. Crossover Frequency
Adjust the crossover frequency of the subwoofer between 50 - 150Hz in accordance with the main speakers when using the
stereo input (refer to page 4). When using the LFE input the low pass filter is not active as this is set by the AVR.
There is also a LED and infra red receiver on the front of the cabinet. The LED will indicate when it is operational. It will be red when
in standby and green when operational. The infra red receiver is there for use with a programmable remote control.
