Audioaccess W.H.E.N. AVR21EN - AUX in (Local Source In); Preout; Or Powered Subwoofer)

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 1/4"
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 on the KP21 rear panel, as
shown in
Figure 29, and tighten with a small-blade screwdriver.
Pull the wire slightly to confirm connection.
3. Terminate local-source ends as appropriate, typically male RCA
plugs. Confirm polarity.
4. Connect to local-source Left and Right line-level audio outputs,
as shown in
Figure 29.
Pre-Out (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 Pre-Out is variable, so local audio will still be
controlled via the KP21 or KP21R remote volume controls.
NOTE 2: The KP21 speaker out and pre-out can be used simul-
taneously. 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 shielded stereo audio cable, strip approximately 1/4"
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– Pre-Out Terminals on the KP21 rear panel, as
shown in
Figure 30, and tighten with a small-blade screwdriver.
Pull the wire slightly to confirm connection.
3. Terminate amplifier ends 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 30.
