Installation

Your new VA-1215XII subwoofer system provides for a number of installation options. Read all the installation information below in order to dete rmine which installation option is best for your system. Rem em ber to perform all in stallation procedures with system power turned off.

Inputs

Your new VA-1215XI I subwoofer is equipped with both speaker­ level and line-level inputs. Use the LINE -IN jacks when connecting your subwoofer to a pre- amp, signal processor, or line-level cross­ over. The FRO M AMPLI FIER jacks connect directly to the speaker outputs of a integrated amplifier or receiver. Your amplifier section will notice no additional loading effects when you use these inputs because of their high impedance.

Volume control

This contro l allows you to balance the output from the subwoofer to the mai n speakers in you r system. This control should be set to achieve simila r volume level from both the main speakers and subwoofer.

Low-pass crossover

Both sets of inputs sum the left and right channels toge ther and the resulting signal is passed through an adjustable low-pass crossover before being amplified . The crossover control allows you to adjust the upper limit of the subwoofer's frequency response from 40 to 120 hz. The subwoofer's 'response will begin rolling off above the frequency you set this control to.

You should set the crossover frequency to obtain a smooth and seamless transition from the subwoofer to the main speakers in your system. If your main speakers are smaller units with limited low frequency output, you may wish to choose a higherfrequency (such as 100-120hz) than you would with larger speakers which have greater low frequency output. With larger speakers, you might start with this control set lower, such as 80hz.

A bypass switch is also provided if you wish to use an external crossover. If you are not using an externa l crossover, we recom­ mend that you use the one provided within the unit for optimum performance.

Phase adjustment

This control allows you the ability to compensate for having the subwoofer in a different location than the main speakers. Ideally, you will have the sound from the subwoofer reach the listening position the same time as the sound from the main speakers. However, if the distance from the listening position to the subwoofer and the distance from listening position to the main speakers differs, the sound from each will reach your ears at adltterent time .

This control allows the signal to be delayed up to 180 degrees so the output of the subwoofer will blend in to that of your main speakers without any cancellation.

Video/Audio swit ch

Many listeners prefer an "emphasized" low end on mo vie soundtracks. This switch sets the VA-1215XII for an additional 3dB of output when in video mode .

Auto turn on switch

The auto turn on switch allows the user to bypass the auto turn on function if desired. When set in the "auto" mode with main power on, the VA-1215XII will turn itself on when an input signal is present. If no signal is present, after several minutes the unit will shut itself off. Whe n set in the "on" mode, the auto turn on/off function is byp assed and the unit will be on wheneve r the main power switch is on.

High pass crossover switch

This switch selects the frequency for the high pass crossover. This cross over is functional on both line and speaker-level outputs. Smaller speakers with limited low frequency output may prefer the
