Gn 30 Oc Installation Module; Defeating The Led Ring - AKG DAM Série Mode D'emploi

• The LED ring will remain lit even if you press the
MUTE button on the transmitter!
Remember that the LED ring does NOT necessarily
indicate that the microphone is open and will not ex-
tinguish unless you switch the transmitter OFF.
• Of course, you may also use the microphone hand-
held, e.g., for questions from the audience.
The GN 30 OC Installation Modules has been de signed
for 1.5 V to 10 V a-b powering. The unterminated cable
provides the following connections:
Red: microphone (hot), supply voltage +
Shield: Microphone (ground), supply voltage -
Black: LED +
Outer shield: LED -
1. Connect the microphone wires to a microphone input
with a-b powering.
2. Connect the black wire (LED +) and the outer screen
(LED -) to a voltage source with an output voltage as
per Table 4 on page 30.
