Multi-Zone Stereo Operation Refer to Figure #2 You can switch your HCA-806A to reproduce a single stereo source through up to three pairs of stereo channels via input cables connected to channels 1 and 2 input jacks only.

Mono Bridging — Channels 3+4 and 5+6 When you bridge channels 3+4 and/or 5+6, your speakers are connected to the bridged channels differently. You bridge by using the red + terminals of the adjacent channel pairs only. Note that bridged connections are made horizontally rather than vertically and that the upper red + terminals have separate markings for bridging. In the bridged mode, channel 4 (and/or 6) output is positive and channel 3 (and/or 5) output is negative. Unbridged speaker connect

In Case of Trouble If you suspect a problem with this unit, first recheck all your connections. If only one channel is inoperative, the trouble may be caused by another component or even a defective hookup cable. However, if the same channel is at fault when you reverse the Left and Right channel pair cables to your HCA-806A (turn it off before moving wires), it may indicate trouble within the power amplifier itself. We suggest you contact your authorized Parasound Dealer or Installer, or call
