MDS-6A  
SECTION 1 - INTRODUCTION  
1.1 - FEATURE OVERVIEW  
6 Sources / 6 Zones  
The MDS-6A enables you to independently listen to and control up to six differ-  
ent 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 trans-  
mits 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”ALLPort

MDS-6A  
2.2 - WIRING MCS CONTROLLERS TO THE MDS-6A  
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.  
2.  
CAT-5 should be used for all MCS Controller wire runs (max 500ft).  
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.

2.3 - SOURCE AND IR CONNECTIONS  
Source and IR Connections  
The MDS-6A has six pairs of line-level audio inputs for the connection of up to six audio  
sources.  
Each audio source has a corresponding source-specific IR output for the connection of IR  
emitters. Source-specific IR outputs allow multiple sources of the same make and model  
to be controlled independently.  
The MDS-6A also has an IR ALL port that can be used to control other system compo-  
nents.
