minimum. Plug the supplied power cord into the mains socket on the rear panel.

Initial Settings

Volume Control: Set the subwoofer volume control to the mid position (12 o'clock) before proceeding.

Crossover Control: This control should initially be set to 45 or 55 Hz when the subwoofer is used with small bookshelf speakers and to 35 or 40 Hz when used with large floor standing speakers.

Phase Switch: The Phase switch should be initially set to 0°.

Connect the red, positive (+) terminal of the Left loudspeaker to the corresponding red, positive (+) amplifier terminal. Connect the black, negative (-) terminals similarly. Tighten the terminals securely. Repeat this procedure for the Right Channel.

Switching On

Plug in the mains plug and switch the power on. Now switch the subwoofer on with the rest of your system.

The subwoofer ON/OFF switch has a rocker action; press “I” to switch the equipment on and “O” to switch it off. When switched on the light beside the power switch and the light on the front of the subwoofer will glow and the subwoofer will be operational.

Basic Tuning

RIGHT SPEAKER LEFT SPEAKER

Volume Setting: Play a programme with extended bass and set the system volume to a reasonable level. Adjust the subwoofer volume control to produce the desired level of bass. The bass should be even and an extension of the main loudspeakers. Do not set the control too high or you will swamp the sound with too much bass and clarity and definition will suffer.

Bi-Wiring

Using separate cables for treble and bass units in a Bi-Wiring configuration reduces intermodulation effects and improves headroom and clarity. To bi-wire, you will need to install two equal lengths of twin core cable between the amplifier and each loudspeaker.

Unscrew each terminal a few turns and remove the metal straps. Connect the cables between the amplifier and the loudspeakers as indicated above and re-tighten all the terminals securely.

Phase Switch: If the bass is indistinct or lacks depth, the Phase switch may need adjustment. Set the switch to 0º and listen carefully to some music with extended bass. If there is insufficient bass output from the sub-woofer set the Phase switch to 180º. Select the position which produces the most natural, extended bass.

Crossover Adjustment. This adjusts the blend between the subwoofer and the main speakers. and enables the system to be set up for optimum bass performance. The higher settings are for use with small bookshelf loudspeakers, the lower settings for large floorstanding models. If you choose too low a setting with small speakers, there will be a ‘hole’ in the bass response; too high a setting with large speakers will result in the upper bass becoming bloated. See the next section for further details.

Again the subwoofer should be an extension of the main loudspeakers.

Mains Operation

When the system is not in use for extended periods, we suggest you switch off the subwoofer to protect it from switching noises caused by domestic appliances, etc. The best practice is to switch the complete system on and off from a central point. Bear in mind that if you play the system with the subwoofer switched off you will get no bass!

Bi-Ampifying (Bi-Amping)

By connecting each loudspeaker drive unit to its own dedicated amplifier the advantages of Bi-Wiring can be extended.

If you own two identical stereo power amplifiers, your speakers may be Bi-Amped. For further details please consult your dealer.

Autopower Switch. (Diamond 10. SX-SUB,10.MX-SUB). If the subwoofer is left permanently on this may result in low level hum or noise from the subwoofer when the rest of the system is switched off. Setting the AUTO switch to ON will automatically turn the subwoofer on when a signal is detected at any of the inputs and turn it off (Standby Mode) after a period of inactivity. We recommend that the AUTO switch be set to ON for normal operation.

In AUTO mode, when the subwoofer is switched on, the subwoofer will become active. If there is no audio input present the subwoofer will go immediately into Standby. As soon as an audio input is detected the subwoofer will then switch on.

When the system is not in use for extended periods, we suggest you switch off the subwoofer to protect it from switching noises caused by domestic appliances, etc.

Always turn the main volume control to minimum when you switch the system on or off.
