OVERVIEW
The M63 is a condenser boundary microphone that features external DSP logic
control, as well as an internal microprocessor logic that provides common DSP
functions in local mode with programmable toggle on/o, momentary talk or mute
switching and (red/green) LEDs indicating active/mute status.
The M63 uses Micros™ series technology oering superior audio performance
optimized for speech and the industry’s first patented internal suspension system
reducing vibration noise.
For installations that do not require elaborate DSP programming, the M63 provides an
easy-to-operate solution without the cost and labor required for DSP operation when
set to internal logic mode.

POWERING UP THE M63
When phantom power (48V) is supplied to the M63, the LEDs will blink red and green
to indicate that the unit is receiving power. Following the power-up sequence, the
LEDs will behave according to the setting specified by the DIP switch configuration.
DIP SWITCH SETTINGS
DIP switches can be accessed by
removing the grille (see Mounting for
removal instructions). To locate the DIP
switches, refer to the illustration at right.

SWITCH USE SETTING
SW1 Determines whether LEDs will be used to
indicate both active and muted states
SW2 Determines whether red or green
LED indicates active state
SW3* Sets microphone to local (internal logic)
mode or external DSP logic control
SW4 Sets microphone’s initial state to ON or MUTE
when phantom power is supplied (SW4 is
disabled when SW3 is in external DSP)
SW5 Determines whether mic is in
toggle or momentary mode

RIGHT: Press to activate (muted on power-up)
LEFT: Press to mute (active on power-up)
RIGHT: Toggle between active and mute status

PIN / WIRE ASSIGNMENTS
The M63 is shipped with two 3-pin terminal blocks. One terminal block is for Audio
connection (audio A+, A-, Ground) and it is the only connection required for audio
and internal logic functionality as described in the overview. The second terminal
block (LED, C.C. Ground) is for use when connected to a DSP for control of LEDs and
contact closure. Two mating pair terminal block connectors are included in the box
for field connection, if needed.
