1 - 6 CHANNEL MIC INPUTS: XLR input connectors for mic or line level signals.
1 - 6 CHANNEL LINE INPUTS: 1/4” input connectors for line level signals.
Each of these inputs may be reconfigured as INSERTS by moving jumper
connector for each channel located inside the RM65b.

PHANTOM POWER: 6 switches for turning on the microphone phantom power for
the XLR inputs, and are numbered for the channel they are assigned to. DOWN is
on, UP is off.
AUX BUS IN: 1/4” TRS stereo input to the main mix bus, and may be used as an
auxiliary stereo input for joining two RM65s together.
FX SEND: 1/4” unbalanced jack for sending the signals assigned by each
channel’s FX Send control out to external effects.
FX RETURN: STEREO 1/4” Tip-Ring-Sleeve jack for inputting signals from
external effects devices. NOTE: THIS JACK IS STEREO ONLY - CONNECTING
A MONO 1/4” TIP-SLEEVE JACK WILL RESULT IN THE RETURN SIGNAL
BEING PRESENT AT THE RIGHT OUTPUT ONLY.
MONITOR OUT: 1/4” unbalanced jack for sending signals assigned by each
channel’s monitor output control to an auxiliary amplifier or monitoring system.
RIGHT and LEFT OUTPUT: 1/4” TRS balanced jacks to be used as the unit’s
main outputs.
USING PHANTOM POWER
Phantom power is a means of powering condenser microphones through the micro-
phone cable. The RM65b has individually switchable 36 volts of phantom power for
each of its 6 channels through the XLR jacks. The DIP switches on the rear of the unit
are for switching the power on and off. When the little switch tab is down, the power is
on. The number on the switch corresponds to the channel that is receiving the power.
If phantom power is not needed, it should be switched off to avoid possible damage
to a microphone, or degraded sound quality.
