Yamaha DSP-A990 ADDING A SUBWOOFER

ADDING A SUBWOOFER

You may wish to add a subwoofer to reinforce the bass frequencies.

This unit provides a line-level subwoofer output, which contains only the frequencies under 200 Hz from the main and center channels. Connect the LOW PASS jack to the INPUT jack of the subwoofer amplifier, and connect the speaker terminals of the subwoofer amplifier to the subwoofer.

With some subwoofers, including the Yamaha Active Servo Processing Subwoofer System, the amplifier and subwoofer are in the same unit.
