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.
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.
“TECH TIP”
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.
