Connect Whole-House System
1. Locate the 4 pin speaker connector plug for SPEAKER A IN
(and remove if plugged in).
2. Strip 1/4" of insulation from the end of each wire for
SPEAKER A IN, coming from the speaker level output of the
whole-house system amplifier. Tightly twist the end of each
wire until no frayed ends remain.
3. Use a small flathead screwdriver or your thumbnail to raise
the locking tabs, exposing the holes on the removable con-
nector plug.
4. Insert each wire into the appropriate hole on the remov-
able connector plug, and snap the locking tab down.
NOTE 1: If switching two speaker pairs, (Figure 4), repeat steps
1-4 above for SPEAKER B IN.
NOTE 2: Maintain proper polarity. Connect the positive terminals
on the TVA50 to the positive terminals on the whole-house ampli-
fier. Connect the negative terminals on the TVA50 to the negative
terminals on the whole-house amplifier. To help you avoid improp-
er phasing, the connector plug is keyed. Insert the smooth side of
the connector plug into the smooth side of the socket. Don’t force
the scalloped side of the connector plug into the smooth side of
the socket.
