The Model ENC-SIWP Source Input Wall Plate serves as a primary audio
source input for the Model ENC-HUB Audio Distribution System Hub. It
provides a connection point for components such as receivers, tuners,
CD players, and computers. A high quality analog-to-digital converter
encodes analog sources to digital audio for the system.
The source input wall plate connects directly to the hub with Cat-5
cable and mounts in a single-gang J-box. Up to four ENC-SIWP wall
plates can be connected to each hub. At each speaker zone, a Model
ENC-DRS Keypad selects between the four primary hub audio sources from
ENC-SIWP wall plates, or from a local audio source connected to the
Model ENC-LIWP Local Input Wall Plate.
The ENC-SIWP features a stereo RCA analog audio input, 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 source switch selects between the coaxial
digital, optical digital, and analog stereo inputs.
For low level signals, a set of gain switches is provided to boost
the signal by 4, 8, or 10 db. The clipping indicator will light if the
signal level is too high.
The system features IR remote control. An infrared repeater system
monitors the infrared receivers at each keypad and repeats the infrared
remote control signals to the audio source components through infrared
emitters connected to the wall plates. IR emitters are sold in a 4-pack
as Model 2171-4.
