outputs are all balanced XLR connectors, and a 1/4" RemoteVolume jack pro-
vides each zone with the means for external volume control.The Microphone
inputs feature automatic ducking for easy paging.
The RM64 is the ideal solution for banquet rooms, offices, restaurant/night clubs,
etc.
NOTE:This unit is intended for professional installation.Certain assumptions have
been made that the installer has the required knowledge to properly install and
setup and operate the RM64.
FEATURES:
•Two Microphone and Four RCA Source Inputs
• Four XLR Balanced Zone Outputs
• 12VDC Phantom Power available for each Mic Input
• RemoteVolume control jacks fro each Zone Output
• Switchable Ducking for the Mic Inputs

CONNECTION
Referring to the diagram above, connect microphones to the MIC
INPUTs and apply phantom power where needed. Connect sources
such as cassette players, CD players, AM/FM tuners, etc. to the
RCA Source Inputs. Note which input each device is connected to
as that input corresponds to its front panel Level control. Connect
the XLR outputs to their respective zone amplifiers and speakers.
The balanced signals are configured to pin 2 hot, pin 3 neutral, and
pin 1 ground. For ground lifting it will be necessary to remove the
connection to pin 1.
For Remote Volume operation, a Tip-Ring-Sleeve plug will need to
be wired to a 10 - 100 K Ohm potentiometer as shown in the dia-
gram below.
OPERATION
SETTING THE DIP SWITCHES
Each input is assigned to a Zone via the four DIP switches nearest
that Input Level control.The zone is assigned when the switch is in
the DOWN position.For example, the switch settings above send
Mic 1 to all four Zones; 1, 2, 3, and 4.Mic 2 is sent to Zone 1 only.
Source 1 is sent to Zone 1 and Source 2 is sent to Zones 2, 3, and
4.
The first four rear panel DIP switches assign which zone has prior-
ity paging, or ducking, when a signal is present at the microphones.
Switches 5 and 6 assign phantom power to the indicated micro-
phone. Shown below; Zones 1, 2, and 3 have paging assigned, and
Microphone 1 has the phantom power engaged.
