Control Out 
(BASIC/ADVANCED) 

A single Common Control Output is provided on the rear of the MRC88 Controller/Amplifier –

Figure 3-(20)

When the Common Control Output is High (+12 volts, 50 mA), this indicates that ‘at least’ one zone is 
powered ON. When the Common Control Output is Low (0 volts), this indicates that ‘all’ zones are OFF. 
Using a 3.5mm mono mini phone connector, this control can be used to close relays (Xantech CC12) or 
turn on an AC outlet (Xantech AC1, AC2) for activity common to the system. Connect one end of the 3.5mm 
Mono Mini jack and the other end to the device to control. Tip=Control Voltage; Sleeve=GND 

(EXPANDED) 

When at least one zone on either the PRIMARY or SECONDARY controller is turned ON, the Control Out 
on the PRIMARY Controller is High (+12VDC). The Control Out on the SECONDARY Controller is inactive 
in EXPANDED mode.

Each zone has a Preamp Out to send ‘zone selected’ audio to another amplifier such as the Xantech 
PA435x or PA4100x. This may be desired for feeding a sub-zone on a separate amplifier, zones that 
require more than 35W, or for sending audio to another amplifier with Dolby™ surround decoding for 
‘theater quality’ audio in the zone. 

 
 

Using good quality RCA-type patch cables, connect the Preamp Out, Left(L) and Right(R) connectors

Zones 7 and 8 have a Remote Mute/Standby output for interfacing and controlling a Xantech PA435X 
(included) or PA4100X amplifier. The control is provided via a Stereo Mini Jack with the TIP controlling 
STANDBY logic (Standby Power On = +12 volts, Standby Power Off = 0 volts) and the RING controlling 
MUTE logic (Mute = +12 volts, Un-Mute = 0 volts).  

 
 

Using a 3.5mm Stereo Mini Jack to 3.5mm Stereo Mini Jack cable, plug one end into the CO1 (or CO2) 
output jack on the rear of the MRC88 Controller/Amplifier 

– Figure 3-(21) 

and the other end into the 

corresponding jack labeled CO1 (or CO2) on the PA435X or PA4100X amplifier.  

NOTE: 

Be sure to set the Control In (CI) switch to ON located on the rear of the PA435X or PA4100X 

amplifier.

Using Xantech Emitters (282M, 283M,284M, or 286M), plug the 3.5mm Mono Mini jack into the appropriate 
zones Zone IR connector –

. Affix the mouse emitter side to the desired 

zone related 

component you wish to control. If more than one device needs to be controlled, use a mono mini to 
stripped-ends wire (PN#6015900) wired to a Xantech 791-44 Amplified Connecting block. Any IR generated 
in the zone (either from MRC-88 Keypad, IR received at the Keypad, or routed from another zone 
(ADVANCED only)) will be passed to this emitter port.
