    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.

    5 and 30 volts (16mA @ 12V). Specifically, it permits the 12 Volt common CO (Control Output) on the Xantech ZPR68 to power one or more PA635's ON and OFF automatically with first zone ON and last zone OFF commands.
  • Page 4 NOTE: The PA635 may also be powered ON/OFF with an external AC line switch into which the power cord of the PA635 is plugged (such as the switched AC outlet of a preamp, timer, etc. with a 10A rating). For this type of operation, leave the POWER switch depressed to the MANUAL ON position.

    +30 VDC is applied to CI for 2 or more seconds. See also item #11). NOTE: The PA635 will always return to last set values (plus any unaltered factory defaults) after main power shut down or after any power interruptions.
  • Page 6: Rc68+ (Or Rc68) Programmer / Remote Control

    Code Group is changed on amplifier pairs you wish to control separately. The STATUS output goes high and low with the AC Power ON/OFF state of the entire PA635. It does not respond to a Common IR OFF/ON (Standby) condition.
  • Page 7 2. Instant Volume Presets. These commands allow random access or direct preset activation of any of 12 fixed preset levels on the PA635. This is useful when setting up "audio scene" ambiance levels for rooms or partial mute actions. The RC68+ buttons that select a fixed level attenuation below Max. Volume is as follows:...
  • Page 8 Be sure to set the RC68+ to the same number! It may be necessary to change the PA635 amplifier pairs to different code groups if you wish to address each pair individually from the COMMON IR BUS (item #15, Fig. 3) or an external common IR bus network when using other Xantech PA635's in large systems, to avoid mutual interaction.

    PA635's and the other heat generating components. 5. When mounting in a 19" (483mm) rack, adding a single RU (Rack Unit) above and below the PA635 will improve convection in heavy use applications (one Rack Unit size = 1-3/4" (44.5mm) in height).

    (or any combination of speakers) is 4-Ohms minimum. 5. Be sure to observe correct polarity by connecting the "+" and "–" terminal from each channel on the PA635 to the corresponding "+" and "–" terminals on each speaker. This will ensure correct "phasing". See Fig. 6 and Speaker Phasing, following.
  • Page 11: Speaker Phasing

    For such applications use the STEREO mode. Use the BRIDGED mode for single speaker, higher power applications, such as in surround sound systems. Use speakers with an impedance rating of 8-Ohms minimum. Figure 7 – Bridged Mode Connections © 2001 Xantech Corporation Page 11...

    CB18 and a 789-44 Connecting Block. 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.

  • Page 14: A Basic Dedicated Ir System - Non Dedicated Keypads And Remotes

    A typical system of this type is shown in Fig. 9, where each remote room has a Dedicated IR path going to the PA635 amplifier pair that controls it. The IR bus is not connected in common as it is in Fig. 8. It eliminates the need for dedicated remotes, allowing you to carry the same remote(s) from room-to-room - that is, remote commands for Volume, Mute, etc., will work in any room from the same remote.

    Using a DC Power Adapter as a Control Voltage Fig. 10 illustrates how a PA635 can be switched ON and OFF via the switched AC outlet on the rear of a preamplifier or other control center. When the preamplifier Power Switch is switched ON, power is applied to the DC adapter which in turn applies 5 V to 30 VDC to the PA635, switching it ON.

    ON automatically. Unit responds intermittently or not at all to IR commands. The PA635 blew its fuse (item #10, Fig. 3) as power was turned OFF using an adapter driving the REMOTE MASTER ON/OFF CONTROL terminals. PROBABLE CAUSE AND SOLUTION Check line cord for good contact in a live AC outlet.
