Model PA635

GENERAL INFORMATION

To enhance the ease of installation and obtain optimum performance from the PA635, we recommend that you first become familiar with all its features and special capabilities by studying the descriptions and instructions in this manual.

The PA635 was designed to meet the audio power amplifier needs of custom installed multi-room, multi-zoned systems with high sonic quality. Common and Local IR control of Volume, Mute, Balance and OFF, for each channel pair, is provided. Its bridgeable 6-5-4-3 multi-channel capability permits a wide variety of uses, such as enough channels to run surround sound home theater or multi-room applications. Specific features and technology are as follows:

Cost/Size Efficiency. The PA635 features 6 conservatively rated 35-watt power amplifiers. This permits each PA635 to drive 3-zones in a multi-zone system, each with a 35 watts/channel stereo amplifier per zone. The rack mountable low profile design, using a large single multiple filtered power supply, delivers high quality at a reasonable price.

IR Controlled Volume Level. Volume can be ramped from zero output to maximum for individual channel pairs, or, as group through the Common Bus inputs, using IR volume control commands from an RC68+ (or RC68). The maximum input sensitivity at full volume is 0. 5 volts for rated output (35 Watts/channel).

Local or Common Bus. Each stereo pair can be fed audio individually via their LOCAL inputs from differing zones or sources. In addition, a single source can be fed, via the COMMON Bus, to some or all stereo pairs as desired. This flexibility permits the installer to drive as many as three rooms in stereo as a single zone system, or three rooms in stereo as a three-zone system --- or divide them up for a combination of both.

Volume Setting Capabilities. The installer has the option of using the volume control of the PA635 as the sole volume control for a zone or the system, or to adjust the PA635 volume to a desired fixed level and use the volume action of a connected preamp instead.

Max-V Setting. This allows the amplifier to be set to deliver a controlled maximum sound level into a zone when the volume is ramped to maximum. This acts as a volume limiter for the system (e.g. to prevent the kids from over-driving wall speakers, etc.).

Output Flexibility (6-5-4-3).Each of the six amplifiers can be driven singly or bridged to allow several channel and power output capabilities. It can be configured into seven power packages as follows:

Six 35-watt amplifiers - 6 total.

One 150 and four 35-watt amplifiers - 5 total. Two 150 and two 35-watt amplifiers - 4 total. Three 150-watt amplifiers - 3 total.

This gives the PA635 great flexibility for use in many applications, such as driving surround sound speaker systems, in addition to multi-room.
