Local Input Wall Plate Setup
Each keypad supports an optional connection to a local input
wall plate (Model ENC-LIWP). The local input plate provides a
connection point for a local audio source in the same room as the
speaker zone, such as an iPod, MP3 player, or a game box.
The local input wall plate connects directly to the keypad with
Cat-5 cable and mounts in a single-gang J-box. It features two sets
of stereo RCA analog audio inputs, a coaxial digital audio input,
an SPDIF optical digital audio input, an IR emitter output jack, a
source selector switch, gain switches, and a clipping indicator.
The input selector switch determines which input is active
(Analog #2, Optical, or Coax). The Analog #1 input (the top two
RCA jacks) has a special override feature. When an audio signal
is detected at this input, it will override the other local wall plate
inputs regardless of the position of the input selector switch. When
the signal at the Analog #1 input ceases, after about 10 seconds,
the local input wall plate will switch to the source determined by the
position of the input selector switch.
Input Gain Switches
The local input wall plate has two sets of internal switches for
adding gain to low level audio signals. Switch #1 is for Input #1,
Switch #2 is for Input #2. In most cases these switches can be left
in the OFF position for no increase in gain.
To add gain to the audio signal at the wall plate, set the switches
as shown in the table below:
GAIN
SWITCH #
RIGHT CHANNEL LEFT CHANNEL
1 2 3 4
+0db OFF OFF OFF OFF
+4db ON OFF ON OFF
+8db OFF ON OFF ON
+10db ON ON ON ON
The clipping indicator will light if the signal level is too high.
IR Out Connection
The local input wall plate features an IR OUT jack for connection to
an infrared emitter. The infrared emitter has an adhesive back so
it can be attached to the source component’s faceplate near the
component’s infrared sensor. The keypad has an infrared sensor
that will repeat a remote control’s signal using the emitters. This
allows controlling the selected source component remotely from
any keypad location.
Local Input Wall Plate Installation
The local input wall plate is usually installed near the keypad.
Determine the location for the local input wall plate and install a J-box.1.
Route Cat-5 cable from the keypad to the local input wall plate J-box.2.
Connect the cable to the Type 110 punch-down 3. J2 (LOCAL) connector on
the keypad. (See Figure 15 for the connector location, see Figure 9 for the
110 punch down wiring standard.) Use a Type RJ-45 connector on the wall
plate end of the cable.
Install the wall plate into the J-box and cover it using a Decora type wall 4.
