Output Audio Connections to Amplifiers

Every room output is connected to an amplifier channel. The ideal companion is the Niles SI-1230 twelve
channel amplifier. A stereo patch cable (with RCA phono plugs on both ends) is connected from each room
output to a grouped pair of inputs on the SI-1230. See Figure 11.

Expanding The System With Up To Six MRZ-6’s

In a system with more than six rooms, additional MRZ-6/SI-1230 combinations can be added, to a maximum
of six MRZ-6s (36 rooms) so that the ALL ON and ALL OFF commands will work reliably throughout the sys-
tem. Two types of system design are supported with multiple MRZ-6 units as follows:

Single Zone

—

One Master MRZ-6

And Up To Five Slave MRZ-6
Units
The MRZ-6 whose Input is connect-
ed to the Preamp/Receiver’s Output
is the Master. The cascade output of
the Master MRZ-6 is then connect-
ed to the input of the Slave MRZ-6.
Using the cascade output, each
Slave MRZ-6 input is connected to
the preceding MRZ-6. All On and
All Off commands will work reli-
ably throughout the system. See
Figure 12.
