INSTALLATION

Power

After making the audio connections, make sure the voltage switch on the back of the SUB85 is set to the correct voltage for your area. Insert one end of the power cable into the IEC receptacle next to the voltage switch and the other end into a live power receptacle.

Slide the power switch to the Auto setting to place the
SUB85 in standby mode or the On setting to place it in
full on mode. The power indicator on the front panel
will light up amber when the SUB85 is in standby mode
and green when fully on.	Power receptacle and voltage switch

Adjustments

Crossover frequency

Set the crossover frequency to match the low-frequency roll-off point of the main speakers. If you don’t know the roll-off point, use the following guidelines:

•For main speakers with a full frequency range, set the crossover between 50 and 80 Hz.

•For main speakers with limited bass extension, set the crossover between 80 and 100 Hz.

•For main speakers that reproduce only midrange and high frequencies, set the crossover between 100 and 200 Hz.

Your receiver or processor may have a bass management feature with settings for large, medium, and small main speakers. Refer to your equipment manual to determine the appropriate crossover setting if you use this feature.

The goal is to set the crossover frequency at the point where the subwoofer reproduces the low frequencies

not reproduced by the main speakers, with very little overlap and no gaps in the overall response of the system. To make this adjustment precisely, you can use a calibration CD or DVD and a sound-level meter.

Volume

Start with the volume set at minimum, raising it gradu- ally until output from the SUB85 sounds about the same volume as output from the main speakers. Again, you can use a sound-level meter to be precise.

Phase

Depending on the location of the SUB85, its output at certain frequencies may be out of phase with the output of the main speakers. This is especially true when the subwoofer and main speakers are very different distances from the listeners.

To compensate for this, try setting the phase switch at both positions. You may ﬁnd that one position provides smoother bass response than the other.
