The Model ENC-HUB Audio Distribution System Hub is an expandable
digital audio system that distributes four analog or digital audio
sources over Cat-5 cable to four independent speaker zones. Each
speaker zone features a backlit keypad with a built-in digital
amplifier that selects the audio source and controls the volume, tone,
balance, loudness, and all other functions of the system. The system
can be expanded with up to eight hubs for a total of 32 speaker zones.
The hub is powered by a Model ENC-PS Power Supply.
Model ENC-DRS Keypads serve as a speaker zone controllers for the
system. Up to four ENC-DRS Keypads can be connected to each hub. The
keypad contains a Class D digital stereo amplifier with 80 watts
maximum output power (40 watts per channel in a 6-ohm load) and is
designed to connect to a pair of 6-ohm or 8-ohm speakers.
Model ENC-SIWP Source Input Wall Plates serve as a primary audio
source inputs and wire directly to the hub. Up to four ENC-SIWP wall
plates can be connected to each hub. Model ENC-LIWP Local Input Wall
Plates serve as a local audio source input at each speaker zone. The
ENC-LIWP wall plate connects directly to a keypad. The keypads select
between the four primary hub audio sources from ENC-SIWP wall plates,
or from a local audio source connected to the ENC-LIWP wall plate. A
high quality analog-to-digital converter encodes analog sources to
digital audio for the system. All system connections are with Cat-5
cable, the keypads and both types of wall plates mount in a single-gang
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.
Two remote controls are available. The Model ENC-REM Micro Remote
Control is a miniature unit that can select the audio source, control
the zone's power, volume, and mute the speakers. The larger Model
ENC-LRM Advanced Learning Remote has all of the features of the basic
remote with the addition of a built-in IR code library and IR learning
capability allowing it to control virtually any audio source component.
The learning remote also has macro capabilities that allow programming
multiple key sequences.
