“TECH TIP” INSTALLATION CONSIDERATIONS

Location

The TVA50 should be installed near the device to be switched, ideally within 15 feet, to avoid signal loss and degradation over long runs of wire. Access to the speaker wires, from the whole- house system and to the local speakers, is also necessary. Installation on a cabinet shelf, sidewall or back panel are all acceptable.

Wire size is expressed by it’s AWG (American Wire Gauge) number.

The lower the AWG

number, the larger the wire, i.e., 20 AWG wire is physically larger than 22 AWG.

Type of Speaker Wire

We recommend 16-gauge stranded copper speaker wire for most connections, and 14-gauge wire for runs longer than 80’. Don’t use wire larger than 14-gauge, because larger wire may not fit into the connectors.

Type of Audio Cable

Shielded stereo audio cables with quality gold-plated connec- tors are recommended. Use low capacitance cables for runs that exceed 15’ to minimize signal loss. Wire runs greater than 50’ are recommended only with cable that has been specifical- ly designed for such applications. Contact your cable manufac- turer for a specific cable recommendation when wire runs exceed 50’.

Power Requirement

Power the TVA50 with an unswitched AC 120V, 60Hz outlet. There is no power ON/OFF switch. The unit will automatically activate when a switching condition (current sense or 12V Trigger IN) is detected.
