INSTALLATION
Preparing for Installation
1. Figure 3 shows a typical application for switching one pair
of speakers to a local source using current sensing. Refer to
the other system applications for switching multiple speak-
er pairs, and use of the Trigger IN/OUT. If your application
is different from those diagrams, use appropriate system
design software or draw it out on paper. Make note of all
parts and components needed for installation, TVA50,
speakers, wire, etc.
2. Once the system has been designed, test the system design
prior to installation to assure performance and eliminate
time wasted running around shopping for parts not speci-
fied or missing.
3. Run all necessary wiring to the TVA50, local source, and
speakers. Label the wires for future reference.
Adjusting Current Sensitivity
The current sensing capability of the TVA50 is adjustable via
a recessed screw located on the bottom of the unit (Figure 6).
This allows for the adjustment of the current sensing
outlet based on the amount of current draw from the local
source component.
1. Plug the power cord of the local source component (i.e. TV)
into the current sensing outlet of the TVA50.
2. Turn the local source component on.
