Notes on multi-controller set-up
Power Toggle Set-up
We recommend in systems with multiple RMZ-955 controllers
(with full AC control from any Zone) that you select source com-
ponents that do not require a “power toggle” command, i.e. com-
ponents that fully power up when AC power is applied, instead of
going into a standby mode.
If sources requiring a “power toggle” command are used, only
one RMZ-955 controller should have the “power toggle” feature
activated (i.e. set to “y” during setup). Make sure that the
“Power Toggle” command is DEACTIVATED for all other
RMZ-955(s).
Even though the default “Power Toggle” setting is OFF, verify that
this has not changed by temporarily connecting an RSM-901 to
the Zone A data terminal of each remaining RMZ-955, entering
Set-up Mode as outlined and pressing the RLC-900 “n” (for No)
key. Continue to hold the “n” key and press the other set-up key
“y” to exit setup.
This is a critical step in a system using multiple RMZ-955s. If
the “Power Toggle” is not deactivated for the additional
RMZ-955(s), source components will not turn on and off properly
— in fact, source components may actually turn off when
RMZ-955s turn on.
Source Component Set-up
Programming of command code sets for source components is
covered in the following section of the manual. However, keep in
mind that in systems with multiple RMZ-955 controllers, it will be
necessary to reprogram these codes for each RMZ-955 in the
system. This must be done from an RSM-901 sensor display con-
nected to Zone A on each controller.
“Engaged” Indicator
The “Engaged” indicator on a remote zone’s RSM-901 sensor/
display(s) will indicate other same-source users only in zones
connected to that particular RMZ-955 controller/amplifier.
For example, in an 8-zone system using two RMZ-955s, a CD lis-
tener in Zone 7 (connected to the second RMZ-955) would have
no indication that another user in Zone 2 (connected to the first
RMZ-955) was listening to the same source. If a third listener in
Zone 4 then selected CD, only the listeners in Zones 2 and 4 (both
connected to the same RMZ-955) would know that someone else
was sharing the same source.
