To make connections for the BRIDGED mode, follow the steps given before for stereo connections, but with the following differences:
1.You may connect the
CAUTION: Be sure Power is OFF when connecting or switching the amp into or out of BRIDGED operation.
2.Slide the MODE switch to the BRIDGED position.
NOTE: Do this only on the amplifier pairs you wish to run in the bridged mode!
3.Connect one speaker wire pair between the
NOTE: Only one speaker is connected per amplifier pair in the BRIDGED mode!
CAUTION: When operating in the BRIDGED mode (particularly when bench testing the amplifier) do not make a ground or any other kind of connection to the amplifier speaker terminals other than those to the individual speakers as shown. Failures caused by inappropriate connections are not covered under the warranty.
Typical Applications
Since the PA635 has an IR control system for each amplifier pair, it can be configured so that each individual room, in a
A Basic Common IR Bus System - Dedicated Keypads and Remotes.
A typical system using a low cost approach is shown in Fig. 8. It does require that a dedicated remote be used in each room that has an IR receiver - that is, remote commands for Volume, etc., are specific for each room.
The system is configured as follows:
1.An RS41AV is used as a low cost
2.Both IR receivers and keypads are used for system control from designated rooms.
3.A CB18 is used as a convenient parallel connecting block for the common +12 VDC, IR signal and GND bus wiring for all the home runs from the keypads and IR receivers in the remote rooms.
4.The Common IR is taken from the #2 connector on the CB18 (connection to any of the other connectors would also work) and run to the Common IR IN on the PA635 with a
5.To provide common IR control to the RS41AV and the Source Components and to power the keypads and IR receivers, three leads are connected between the CB18 and a
6.Since a common IR bus is used to keep costs low, each of the amplifier pairs on the PA635 must be set to a different IR Code Group number, so that Volume, Mute, Balance and Standby ON/OFF in each room can be adjusted independent of the others. To make Code Group changes, refer to the RC68+ Programmer Instructions.
NOTE: When shipped from the factory, all amplifier pairs of the PA635 are set to Code Group number B0. You may, for example, leave the #1 amplifier pair at B0 and change the other two to C0 and D0, etc. Just be sure not to use a group number that is used by any other Xantech product connected on the same IR bus (e.g. #20 used on the RS41AV).
