•Since it includes adjustable code groups, the user may inadvertently alter the installer configurations.

•Also, since the user will require IR commands from other brands of equipment to control the total system, in addition to those of the PA1235, all commands should be consolidated into one learning device, for ease of use.

3.OFF Command. Turns the amplifier pairs (both LOCAL and COMMON) to Standby OFF mode. The "Standby OFF" mode remains until the MUTE OFF command is sent.

NOTE: This command is inhibited automatically when the CI terminal is driven high with an external control voltage. Refer also to items 9 and 11, Fig. 3.

4.C-BALCommand. Instantly returns the balance to the Center position (equal volume in each channel) from any previous setting.

5.Balance Commands. When the Balance "arrow" buttons are pressed, the audio output will move to the left or right (with a 2 dB/step reduction in the attenuated channel) with each left or right press.

NOTE: These commands do not ramp. That is, no change will occur if the BALANCE buttons are held down continuously!

6.MAX-V. This command saves a maximum desired volume level for a zone or rooms (both LOCAL and COMMON). The volume is first adjusted to what is desired as a maximum level. The MAX-V button is then pressed, locking in this setting. This acts as a volume limiter for the system (e.g. to prevent the kids from over-driving wall speakers, etc.).

To unlock the MAX-V setting, press the ADJ-OFF button (item #10).
