2.3FM•AM ANTENNAS

To connect the AM loop antenna, press the spring-loaded tabs of the

AM ANTENNA connector and insert the bare ends of the two wires.

Move the antenna until best reception is found.

To connect the FM antenna, connect the two wires to the screw terminals of the

 

75-ohm to 300-ohm adapter, then connect the adapter to the FM ANTENNA

 

connector. Move the antenna until best reception is found – this is usually a “T”

 

formation. If your cable company provides FM service, you can connect the cable

75-ohm to 300-ohm adapter

directly to the AVM 50.

2.412 VOLT TRIGGERS

If your other components have provisions for a trigger, you can automatically turn them on and off together with the AVM 50, or when a specified Source is selected. Connect a trigger output from the AVM 50 to the trigger input of your power amplifier, display, etc., using a cable with 3.5mm mono mini plugs.

Trigger3 is designed to provide the extra current (up to 200 mA) required by relays in larger projectors and motorized screens. Depending on the equipment, a thicker wire gauge may be required (consult your dealer).

The AVM 50 provides flexible trigger options. From the factory, all the triggers are disabled. Through the Setup Menu, you can specify the conditions for enabling triggers (see section 3.10).

2.5POWERED I.R. (INFRA RED) RECEIVERS

External IR receivers allow the Remote Control to be used from other locations in your home. Once an IR receiver is wired to a selected room, connect it to one of the three I.R. RECEIVER inputs through the removable terminal block. To use the terminal block, remove it from the AVM 50, loosen the proper screw, insert the wire in the slot, tighten the screw onto the wire, and insert the terminal block into the AVM 50. See section 3.10 for Setup information.

In addition, there is no need for an external 12V supply to power the receivers – use the AVM 50’s built-in supply instead for up to three IR receivers, and connect according to the IR receiver manufacturer’s instructions.

Custom Installers: The AVM 50’s IR inputs sense modulated 38 kHz carrier, not demodulated data. With some control systems, an emitter face-to-face with an IR receiver may be needed.

2.6I.R. (INFRA RED) EMITTERS

External IR emitters allow control of your source components from any location in your home that has an IR receiver wired to the back of the AVM 50. After positioning the IR emitter according to its instructions, connect it to I.R. EMITTER output. Commands that come in through the rear I.R. RECEIVER connections are re-transmitted through the IR emitters.
