User manual RUSSOUND AB-3.2

[. . . ] If you are listening to the Russound system (AMP A) and turn on your home theater (AMP B), the AMP B audio will override the AMP A audio and the home theater sound will be heard over the local speakers. The AB-3. 2 includes a sensitivity trigger adjustment to adjust the volume level where switching occurs. It also includes a delay adjustment to prevent source switching during the absence of a signal. Country-specific 12VDC detachable power supplies can be substituted for use outside the U. S. Installation To minimize the possibility of picking up extraneous noise, it is recommended that the AB-3. 2 be located near the AMP B source. [. . . ] If this on/off switching is too distracting, you can increase the delay control setting to compensate. Delay Setup The mid-range setting of the delay control provides a delay of approximately 10 to 15 seconds. If you use the AB-3. 2 primarily at lower volume levels you will need to add more delay to prevent the AB-3. 2 from incorrectly switching back to the AMP A Input during quiet periods in the programming from AMP B. Adjust the Delay control clockwise to increase the delay time and counterclockwise to reduce the delay time. Note: If AB-3. 2 relays continually click, adjust the trigger control to less than 1/4-turn or until relays stop clicking.
