The Model ENC-DRS Keypad serves as a speaker zone controller for the Model ENC-HUB Audio Distribution System Hub. Up to four ENC-DRS Keypads can be connected to each hub. Each keypad in the system selects its speaker zone's audio source, controls the volume, tone, balance, loudness, and all other functions of the system. The ENC-DRS contains a Class D digital stereo amplifier providing up to 100 watts maximum output power (50 watts per channel at <1% THD into a 4-ohm impedance load) and is designed to connect to a pair of 4, 6, or 8-ohm speakers.

The keypad connects to the ENC-HUB with Cat-5 cable and mounts in a single-gang J-box (minimum 2-3/4" unobstructed depth required). For maximum output installations, four independent high current power supply outputs are provided on the hub for supplying dedicated keypad power through 2-conductor 16 gauge wire.

At each speaker zone, a ENC-DRS Keypad selects between the four primary hub audio sources from Model ENC-SIWP Source Input Wall Plates, or from its local audio source connected to the Model ENC-LIWP Local Input Wall Plate.

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 input plates. IR emitters are sold in a 4-pack as Model 2171-4.
