Connections

Before connecting your subwoofer, make sure all equipment is switched off. If you have any doubts about connecting your subwoofer, we recommend you contact your local authorized dealer.

Connecting To A Multi-Channel A/V Amplifier

Use the SUBWOOFER OUT on the back of the A/V unit (RCA connectors) to connect it to one of the two inputs on the back of the subwoofer as shown below.

Connecting To A Stereo Amplifier

Use the PRE-OUT (L+R) output on your pre-amp or stereo amplifier (see owners manual) and connect then to the inputs on the subwoofer as shown below.

Powering ON

Powering ON should be carried out as follows:

• Check that all connections are correct and that the volume of your amplifier is set to minimum.
• Connect the power plug.
• Switch the ON/OFF switch to ON.
• Adjust the volume, frequency and phasing (see Positioning & Settings).

NOTE: Cut off the power supply of the subwoofer by using the power switch when it is not in use for several days.

Positioning And Settings

Position your subwoofer in the forward listening zone (if possible between the two main speakers) for a better sound resolution.

This subwoofer can be used with any type of loudspeakers.

The ideal setting should correspond to a realistic reproduction of the bass and be adjusted to compliment your main loudspeakers. You should not feel the subwoofer, the bass should appear to come from main speakers.

The phase inversion switch can be used to reach the best result possible. This switch is used to invert the phase of the sound signals coming from the subwoofer. Depending on the placement of the subwoofer in the room in relation to the main speakers, inverting the subwoofer phase can lead to a better coherence to the systems global response in the bass frequencies.

We recommend you to carry out various tests until finding the setting which suits you the best. Use a recording you know well and study the result according to your taste and expectations.

Troubleshooting

If the equipment fails to operate correctly, check the points below. If the problem continues, a malfunction may be possible. Disconnect the power supply immediately and contact your dealer.
