it shall remain readily operable. Mains plug is used as the disconnect device. To be completely disconnected from the power input, the mains plug of the appliance
must be disconnected from the mains completely.
10.
Power-cord Protection – Power supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon or against them, paying
particular attention to cords at plugs, convenience receptacles and the point where they exit from the appliance. The main plug should not be obstructed OR should
be easily accessed during intended use.
11.

It is possible to manually adjust the set up of the V-20W instead of using the
amplifier / receiver.
A. Crossover Frequency Control
Positioning
As the sub-bass (low frequency) sound produced by the subwoofer is nondirectional it can be positioned almost anywhere in the room, although it should not
be placed too close to the listener. For optimum performance try the subwoofer in
different positions to find the best place for a boom-free sound.
The crossover frequency control changes the upper cut-off frequency of the
subwoofer. Its effective range is from 40Hz to 140Hz at a rate of 24dB per octave.
The frequency control should be adjusted to achieve the smoothest integration
between the main/satellite speakers and the
subwoofer. Clockwise rotation will increase the cut-off frequency and anti-clockwise
rotation will decrease the cut-off frequency.
Connection to V700
Refer to P.9.
Combined Output
Set the volume on the V-20W to the 7th dot.
Adjust the subwoofer volume with your TV remote.
Press the mute button 3 times quickly to enter subwoofer volume control mode.
LED indicator on V700 should show a slow pulse.
Subwoofer Output
Satellite Output
1. Ideal crossover - flat response.
2. Crossover point set too low - causes dip in combined response.
3. Crossover point set too high - causes hump in combined response.
B. Phase Control
Connect to the amplifier LFE subwoofer output.
The phase control will normally be set at 0º but more output level can sometimes
be achieved in the 180º position, particularly when the subwoofer is far away from
the satellite speakers.
All inputs work simultaneously.
C.Volume Control
Set the subwoofer frequency on the amplifier / receiver to 80Hz (refer to the
amplifier / receiver manual).
Set the crossover on the V-20W to 140Hz.
The volume control adjusts the output level of the subwoofer in relation to the
satellite or AV speaker output level. Clockwise rotation to increase the output level
or anti-clockwise to decrease the output level.
Set the volume on the V-20W to the 7th dot.
Bass Boost (EQ)
Ensure that the satellites are set to the appropriate configuration in the amplifier /
receiver menu (refer to the speaker manual).
The bass boost control is intended to adjust the response of the subwoofer to
compensate for room conditions and user preferences. Boost is switchable between
0, +6 and +12dB at around 65Hz.
Connection to AV amplifier / receiver
Adjust the subwoofer volume on the AV amplifier / receiver to your desired level
(refer to the amplifier / receiver manual).

REMEDY
Mains indicator light does not come on.
Check that the subwoofer is plugged into the mains supply and that any switches are on.
Check any fuses (including the plug) or circuit breakers on the mains supply which may affect the power to
the subwoofer.
Ensure that all equipment is switched on.
Contact your dealer for further advice.
Mains indicator light is on but no sound comes from the
subwoofer.
Check and adjust the level control.
Check the output sockets on the source equipment are correctly switched and adjusted to
provide sufficient level to drive the subwoofer.
Check that all connections between the subwoofer and the source equipment are correct and
adjust as necessary.
If there is still no sound.
Contact your dealer for further advice.
Red light no sound.
Check volume levels of subwoofer and amplifier/receiver.
Green light no sound.
