Speaker Mute Relay
The
Speaker Mute Relay
is typically used in situations where a multi-channel amplifi er has been added to an MZC Zone
Pre-out for additional rooms or ‘sub-zone expansion’. The MODE 3.1 Speaker Mute Relay gets connected to a SpeakerCraft
EPR-1.0 Speaker Muting Relay
. This allows the individual room keypads to mute their corresponding speaker pairs and
not the zone, which would mute all of the rooms in the ‘sub-zones’. The following describes the connections for the Speaker
Relay Mute and sub-zone speaker connections.
1. Connect
ZONE SPEAKERS L+,L-/R-,R+ OUTPUTS
from the MZC-88 or an external amplifi er to the
EPR-1.0 AMPLI-
FIER Terminal L+,L-/R-,R+ INPUTS
.
2. Strip approximately
1
⁄
4
inch of each lead and twist the stripped ends so there are no loose strands that can cause shorts.
3. Connect the
EPR-1.0 SPEAKERS L+,L-/R-,R+ OUTPUTS
to the
L+,L-/R-,R+ terminals
on each speaker pair as appro-
priate.
4. Connect the
WHITE STRIPE LEAD
from the
EPR-1.0
to the
+RELAY Terminal
on the
MODE 3.1
.
5. Connect the
BLACK LEAD
from the
EPR-1.0
to the
-RELAY Terminal
on the
MODE 3.1
.
6. Visually check for loose ends. Lightly pull the wire to confi rm connection.
7. Install speakers into dry-wall cut-outs or SpeakerCraft InstaLLock™ New Construction Brackets (if used) as appropriate.
NOTE:
EPR-1.0 Relay mute will not function without proper confi guration in EZ-Tools.
