Operation Manual

Positioning/Initial Set Up
Leave the subwoofer unplugged from the mains until the installation procedure is completed. The
subwoofer should now be sited in the most suitable position, preferably not directly in the corner of the room as
this may cause excessive bass ‘boom’. Once a desirable position is achieved it is important to check if the cables
are long enough to reach comfortably without being under tension. The optimal control settings will depend
entirely on your system configuration. For initial trials set the controls as follows:
Volume Control Should be set to minimum
Frequency Control Should be set to the minimum position (40Hz)
Phase Control Should be set to zero degrees
Power Mode Switch (R370
HD
Only) Should be set to ‘Auto’ (if not using 12v trigger)
EQ Setting (R370
HD
Only) This will be set as EQ1 by default when powered up
Mode setting (R360
HD
Only) This should be set to Music:
Low Pass Filter Switch (R370
HD
Only) Should be set to the ‘Out’ position
Input connections can be made at this stage before the power is connected to the subwoofer. Do not connect
the 12v trigger yet.
Never connect or disconnect any leads with the subwoofer switched on.
Set Up
Once the input cables are connected and the controls are set in accordance with the initial set-up procedure
above, the subwoofer can be connected to the mains power supply and switched on at the mains power switch.
Do not play any music at this stage. Power Mode Switch in the ‘Auto’ position, the unit should remain in standby
with the power LED on the amp panel should be red, and the EQ1 button illuminated blue (R370
HD
only) until the
AV amp is turned on or a signal is received.
To manually set up you sub, play a variety of music/ film excerpts that you are familiar with starting at a very low
volume level, increasing to an average listening level once you are sure everything is working correctly. Please
now follow the instructions below: -
For use with an AV amp/receiver (product with Subwoofer output) please select the low pass filter switch to •
the ‘Out’ position. Otherwise select low pass filter switch to the ‘On’ position. This engages the crossover
frequency control on the subwoofer (please refer to pages 5 & 7).
If u• sing the crossover frequency control please adjust in accordance with the table on page 6. Further fine-
tuning may be required.
The Phase Control can now be set, please refer to pages 5 & 7 for further information.•
It is important to try a variety of music and film excerpts with which you are familiar in order to obtain the optimum
overall settings.
A lot of AV amplifiers/ receivers have an auto set up on them. If you use this to set up your sub, please remember
to go back into the settings of your AV amp and check them. You may need to go back and set it up manually,
both on the sub and on the AV amp.
12v Trigger (R370
HD
only)
When you are happy with the set up of your R370
HD
, turn off both the source and your sub woofer. Connect the
supplied lead to your amp and your sub. The Power Mode Switch on the R370
HD
can be left in any position. The
Mains Power Switch should be left in the ‘on’ position. With the trigger connected, the sub will turn on when
the source is turned on and will stay until the source is turned off. This is the most energy efficient way of using
your sub woofer.
