8.To keep the system cost low, no AC power management is included. The user would need to operate the power switching for each component individually, using front panel power switches, or IR, as appropriate.
Individual room Standby ON/OFF is provided, however. The STATUS of Standby ON/OFF is indicated at the IR receivers and keypads via the STATUS line connection to each room, as shown.
9.This system is primarily set up to distribute music to each room. A video feed to a single room could also be done at low cost. However, video distribution to all rooms would add additional layers of complexity and cost that would best be handled by a
10.When connecting speakers for each room, be sure to observe correct polarities as shown in Fig. 6.
A Basic Dedicated IR System - Non Dedicated Keypads and Remotes.
A typical system of this type is shown in Fig. 10, where each remote room has a Dedicated IR path going to the PA1235 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
This system is similar in many respects to the previous system (Fig. 8), but differs as follows:

5.The desired volume and other commands from the RC68+ Programmer (see Fig. 4) need to be "taught" into learning remote controls (such as the Xantech URC types) and Smart Pads used in the system, either directly or by using Dragon Drop IR™.
Connecting the REMOTE MASTER ON/OFF CONTROL Terminals
As mentioned under "PA1235 PANEL AND FEATURE DESCRIPTIONS", the REMOTE MASTER ON/OFF CONTROL terminals allow the power to the entire PA1235 to be turned ON and OFF by a remotely applied DC Voltage. Figs. 9 and 11 are typical applications using this feature.
Using a DC Power Adapter as a Control Voltage
Fig. 10 illustrates how a PA1235 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 PA1235, switching it ON.
•Similarly, when the preamplifier is switched OFF, the DC voltage to the PA1235 is removed, turning it OFF.
