5. Volume Control
This control allows the level or volume to be adjusted in order to achieve a balanced overall
sound. To use this facility you will need to play a selection of familiar music or film excerpts.
Start with the volume at minimum and increase the level control until a balanced sound is
established. If using an AV processor or AV receiver amplifier, the system can be adjusted
by the test tone function within the set-up features. (Refer to the set up section in the AV
processor or AV receiver amplifier user guide.) When the MASS W200 is correctly set-up,
you should not be able to identify its location easily in the room.
6. Bass Switch
This switch tailors the bass response of the MASS W200 to your tastes. There are three
settings: Music, Movies and Impact. In Movie mode, it provides a relative flat response
down to 35Hz. Music mode is -2dB down on Movie mode but goes lower, all the way down
to 30Hz. Impact mode is +3dB up on Movie mode and comfortably goes down to 40Hz.
7. Phase Control Switch
The Phase Control is used to synchronise any delay between the MASS W200 and main/
satellite speakers. When the MASS W200 is in phase with the main/satellite speakers the
sound should be full bodied. Sit in a normal listening position whilst adjusting the phase
switch. Help from another person may be required. When set correctly the location of the
subwoofer should be almost undetectable. Experimentation is advisable in order to achieve
optimum results. However it should be noted that in most cases the phase control switch
should be set to 0 degrees, especially when using a digital AV processor or AV receiver
amplifier.
8. Power Mode Switch with On-Auto Facility
With the switch in the 'On' position, the subwoofer is permanently switched on under all
conditions. In the 'Auto' position the subwoofer will automatically switch on when an input
signal is received and will remain on for a period of time without receiving a signal before
switching into standby mode until a signal is received once more.
9. Mains Power Switch
The Mains Power Switch should be switched to the 'Off' position when the MASS W200 is
unused for extended periods. The switch must be in the 'On' position for the subwoofer to
function.
WARNING: Due to the mains switch being located on the rear panel, the apparatus must be
located in the open area with no obstructions to access the mains switch.
10. Figure 8 Mains Power Connector
The MASS W200 is supplied with a two-pin mains input socket for connection to the mains
supply. Use ONLY the appropriate mains lead provided with the product.
The LED on the top of the cabinet indicates whether the unit is in stand-by mode or operational.
It will be illuminated red when in stand-by, and green when operational.
