INSTALLATION MANUAL

6 Sources / 6 Zones

The MDS-6A enables you to independently listen to and control up to six different audio sources (i.e. Tuner, CD, Tape Deck - and the audio signals from your VCR, DVD, and Satellite Receiver) in six distinct listening areas or “zones”.

12 Channel x 40 WPC Power Amplifier

The MDS-6A features 12 channels of amplification capable of delivering 40 watts per channel into 8 ohms. The MDS-6A provides more than enough clean, dynamic power to drive a house full of speakers all day long!

Compatible with MCS Zone Controllers and IR Receivers

The MDS-6A’s zones can be controlled using MCS-1A Zone Controllers, MCS-2A Programmable Zone Controllers, and/or IR Receivers. Add multiple MCS Controllers and/or IR Receivers for maximum flexibility.

User Feedback to All System Controllers

Unlike other basic multi-zone systems, the MDS-6A receives IR data and transmits feedback to MCS Controllers. These features inform the user of which Source is currently selected, Zone ON/OFF Status, Mute, Do-Not-Disturb, Whole-House Music Status, and more!

MCS Controller RJ-45 Jacks and Removable Speaker Terminals for Easy Connectivity

In addition to the six plug 'n play RJ45 jacks for MCS Controllers and IR Receivers, the MDS-6A features installer-friendly removable speaker terminals which accept up to 14 AWG wire.

6 Source-Specific IR Output Ports Plus 1”ALL” Port

Six source-specific IR output ports enable multiple ‘same make/model’ components to be used without conflict or interference. An IR ALL port is also provided.

System Specs

Each of the MDS-6A’s Zone Controller RJ-45 Jacks provides 12VDC/300mA. These Zone Keypad connections are capable of driving a maximum of TWO

MCS Controllers

per

zone.

MCS Controller Connections and MDS-6A Wiring

1. CAT-5 should be used for all MCS Controller wire runs (max 500ft).

2. MCS Controller wire runs can be terminated directly to RJ45 connectors

and then plugged into the MDS-6A.

3. Use RJ45-to-Pigtails Interface Cables and a point-to-point punchdown

block to facilitate the termination of MCS Controller wire runs. Use of a punchdown block eliminates crimping and pinout errors while providing a neat, on-wall wire management solution.
