AUX In (Local Source In)
This connection allows the audio from a local source such as a CD/DVD player, DVR,
cable/satellite receiver or Video Game to be played through the KP21 amplifier and local room
speakers.
1. Using shielded stereo audio cable, strip approximately ¼” and twist the ends until there are
no loose strands that can cause shorts.
2. Insert the twisted ends into the appropriate slots on the
R+/R-
and
L+/L- AUX IN Terminals
[hexagons 29, 30]
on the KP21 rear panel as shown in
Figure 96
, and tighten with a small
blade screwdriver. Pull the wire slightly to confirm connection.
3. Terminate local source end as appropriate, typically male RCA plugs. Confirm polarity.
4. Connect to local source Left and Right line level audio outputs as shown in
Figure 96
.

PREOUT (Keypad To Local High Power Amplifier or Powered Subwoofer)
This connection allows the KP21 Keypad to output variable line level audio to a local device such
as a high power audio amplifier or powered subwoofer. The KP21’s 50 Watts per channel digital
amplifier will provide quality high level audio output that will satisfy most applications. In some
situations such as very large rooms or outdoor zones, an external high power amplifier may be
desirable. In other situations it may be desirable to add a powered subwoofer to enhance low
frequency audio performance.
NOTE 1: The PREOUT is variable, so local audio will still be controlled via the KP21 or KP21R
remote volume controls.
NOTE 2: The KP21 speaker out and preout can be used simultaneously. Both are variable outs
and controlled via the KP21 or KP21R remote.
NOTE 3: There are other applications such as connecting to a line level audio input on a local TV
when external speakers are not used in a particular zone. (Set TV volume to a good level and
control the audio level with the KP21 or KP21R remote volume controls.)
1. Using stereo shielded audio cable, strip approximately ¼” and twist the ends until there are
no loose strands that can cause shorts.
2. Insert the twisted ends into the appropriate slots on the
R+/R-
and
L+/L- PREOUT Terminals
[hexagons 26, 27]
on the KP21 rear panel as shown in Figure X, and tighten with a small
blade screwdriver. Pull the wire slightly to confirm connection.
3. Terminate amplifier end as appropriate, typically male RCA plugs. Confirm polarity.
4. Connect to the amplifier’s Left and Right line level audio inputs as shown in
Figure 97
.
