Example 2: In-Wall Volume Control With a Fixed Output Device

In some applications, it may be desirable to control speaker level of both the whole-house sources and the TV, or perhaps a local CD or DVD player that might not have a variable output, with the in-wall volume control. In this application, the vol- ume control would be connected to the output (SPEAKER OUT) of the TVA50 and the fixed line level output of the TV or local device would be used.

NOTE: If driving speakers and using volume controls on both SPEAKER OUT A and B, minimum acceptable impedance is 4 ohms. Be sure to check speaker specifications and impedance magnifying settings on the volume controls to assure proper per- formance. Exceeding this load will cause the TVA50 to go into pro- tection and shut down.

12V Trigger Out

The TVA50 has a 12VDC 200mA Trigger OUT that will be acti- vated in the current sense mode or when 3-30V AC/DC is detected on the Trigger IN terminal. This Trigger OUT voltage can be used to control 12VDC controlled devices such as drapes, screens and TV lifts.

12V Trigger Out and a TV lift

In certain exotic applications, it is desirable to keep all compo- nents hidden from sight when not in use. A TV mounted in a lift cabinet is a perfect example. When not in use, the TV is hidden away in an attractive furniture quality cabinet. A motorized lift mechanism will raise the TV up out of the cabi- net for use when activated by voltage, IR or RF commands.
