Microphone Wiring

Looking into the 3 pin Lemo mic connector from the out-
side of the transmitter, the pin centered in the two guide
slots is pin 1 (ground). Pin 2 is a 1k resistor to ground.
Pin 3 is the audio/bias connection for two-wire micro-
phones and line inputs.

Pin 3
Voltages, polarity, impedance and line level for all signal
sources are selected by menus. Menu selections in-
clude presets for popular microphones, and a sub-menu
for manual setup. Refer to the section entitled Setup
Screens on the previous page for details.
Two-wire electret lavaliere:
Pin 1 - Ground (shield)
Pin 3 - Audio and Bias
Sanken COS-11 lavaliere
Recommended Wiring:
Pin 1 - Shield (ground)
Pin 2 - White (source load)
Pin 3 - Black (bias and audio)
NOTE: The COS-11 can also be wired in a two-
wire configuration. Contact Plus24/Sanken for
details.
The Sanken CUB-01 is not supported.

Line Input Wiring and Use

Pin Configuration:
Pin 1: Shield (ground)
Pin 2: Audio

Rio Rancho, NM
Unlike the old configuration,
the new line input configura-
tion requires no fixed gain
setting. The gain setting can
be adjusted as needed for the
specific input level used.
Micro Body Pack Transmitter
Old Configuration:
Pin 1: Shield (ground)
Pin 3: Audio and bias
NOTE: This line input configuration is found on
the following serial numbers and lower:
- Band A1 S/N 2884 and lower
- Band B1 S/N 2919 and lower
- Band C1 all S/Ns
Transmitter Settings:

Note: This gain setting may seem "backwards"
or illogical, however, it is correct due to the
unique nature of the SSM input circuitry.Input
Jack Configuration
Input Jack Configuration
The pin centered in the two guide slots is pin 1 and is
ground. At 7 o'clock is pin 2 with a 2k resistor to ground.
That 1k is a source load for the Sanken COS-11 to save
putting a resistor in the connector. At 4 o'clock is pin 3,
the servo audio input.
Pin 1 - ground
Pin 2 - 1k source load to ground
Pin 3 - servo input
Voltages, phase, impedance, and line level for all mics
signal sources are selected by menus. Pin 3 is the only
connection for all mics except for the aforementioned
Sanken COS-11. Countryman, DPA, Sanken COS-11 and
standard two wire mics can be configured in the menus.
The Sanken CUB-01 is not supported.
Locking the Controls
The keypad can be locked to prevent inadvertent chang-
es to be made to the transmitter. Press and hold both the
UP and DOWN arrow buttons for several seconds until
a countdown is completed on the LCD. The display will
show unloc 3...2...1 and then Loc will appear. To unlock,
remove the batteries.
NOTE: This function is NOT affected, either
locked or unlocked, by turning the power off.
