Interconnect cables

When installing your VA-806/907 using the line-level inputs/out- puts, you should use standard shielded phono cables. Always keep the lines as short as practical to minimize noise.

When using the speaker-level inputs/outputs, use the same quality speaker cable to your subwoofer as you run to your satellites.

Placement

The VA-806/907 operates at very low frequencies which are prima- rily non-directional. While it is recommended that the subwoofer be placed on the same plane as the satellite speakers, room and system conditions often dictate otherwise. See your dealer for help in placement.

150 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 higher frequency (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.

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 a different time.

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

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-806/907 will turn itself on when an input signal is present. If no signal is present, after several minutes the unit will shut itself off. When set in the "on" mode, the auto turn on/off function is bypassed and the unit will be on whenever the main power switch is on.

Power switch

The master power switch is located on the right half of the unit. This slide style switch is the main on/off for the unit. This switch should be set to up for on , down for off.
