M63
INSTALLATION &
OPERATING GUIDE

1. Mark placement using the provided M63 template.
2. Remove (2) screws from LED plate; remove plate. (figure 1)
3. Remove grill (figure 2)
4. For wood screw mounting evaluate surface depth and select appropriate screw
length (2 ea as provided) [ 1 ¼” #6 ]
5. For machine screw mounting evaluate surface depth and select appropriate screw
length (2 ea as provided) [ 2” 6/32 machined screw with nut and washer ]
6. Refasten grill and LED plate
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 oering 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.
*When connecting to a DSP, DIP switch 3 is always set to the left position.
SWITCH USE SETTING
SW1 Determines whether LEDs will be used to
indicate both active and muted states
RIGHT: Active and mute status with alternate color LEDs
LEFT: Only active state will be indicated by LEDs
SW2 Determines whether red or green
LED indicates active state
RIGHT: Active is green
LEFT: Active is red
SW3* Sets microphone to local (internal logic)
mode or external DSP logic control
RIGHT: Local control
LEFT: External DSP logic
SW4 Sets microphone’s initial state to ON or MUTE
when phantom power is supplied (SW4 is
disabled when SW3 is in external DSP)
RIGHT: Press to activate (muted on power-up)
LEFT: Press to mute (active on power-up)
SW5 Determines whether mic is in
toggle or momentary mode
RIGHT: Toggle between active and mute status
LEFT: Momentary. Press and hold button to maintain
either active or muted state (as specified by SW4)
SW6 Not assigned
SW1 LEFT: LEDs for active only SW1 RIGHT: LEDs for active and muted
SW2 LEFT: Active LED color red SW2 RIGHT: Active LED color green
SW3 LEFT: External DSP logic SW3 RIGHT: Internal local logic
SW4 LEFT: Mic on at power up SW4 RIGHT: Mic o at power up
SW5 LEFT: Mic switch momentary SW5 RIGHT: Mic switch toggle
SW6 LEFT:Not assigned SW6 RIGHT:Not assigned
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.

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.
CONNECTING TO A DSP
IMPORTANT:When connecting to a DSP, DIP switch 3 is always set to the left position.
