The diagram to the left shows
that the SDA-120 Amplifier can
be located near the surround
sound receiver (recommended)
and connected to the In-Wall
Subwoofer unit using 2-conduc-
tor, in-wall speaker cable.
The connection of the inwall subwoofer in this example is performed as such: the SDA-120 ampli-
fier is connected to a receiver’s LFE or Subwoofer Out connector using a shielded subwoofer cable
(available from HTD), and the SDA-120 and In-Wall Subwoofer are connected using standard
2-conductor 14-gauge speaker cable.
