Connecting the optical microphone 

왘

Before connecting the optical microphone, remove the protections caps
from the microphone connections 

1

 and 

2

 of the central unit. Keep the

protection caps in a safe place for reuse during transport or storage. They
protect the microphone connections against dirt.

왘

Connect the duplex connector 

 of the optical microphone to the micro-

phone connections 

1

 and 

2

 of the central unit. Please observe the

correct insertion direction of the connector. The duplex connector is
connected the correct way round when the label on the connector is facing
downwards as shown.

Switching the central unit on/off

After connection to the mains, the device switches on automatically and the

ON

 

button

 lights up. 

왘

Press the 

ON

button

 to switch the MO 2000 CU central unit on or off. 

Note:

If the power supply is interrupted for several seconds (e.g. due to a power
failure), the device switches on automatically even if it was switched off
before. 

Adjusting the sensitivity

With the microphone connected and both the gain switch 

 

and the level

control

 set to 0 dB, the specified sensitivity (mV/Pa) is obtained. 

왘

Use the gain switch 

 to increase the output voltage level by 20 dB

(tenfold increase) or 40 dB (hundredfold increase). 

왘

Use the level control 

 to steplessly adjust the output voltage level

between –15 dB and +15 dB.

Overload indication

The 

OVERLOAD

LED

 indicates both positive and negative voltage peaks.

If the 

OVERLOAD

 LED

 lights up:

왘

Use the gain control 

 and/or the level control

 to reduce the output

voltage level so that the 

OVERLOAD

 LED

 no longer lights up.

Risk of damage to fiber optic cable!

Fiber optic cable must not be bent like conventional cable!

왘

When installing fiber optic cable, make sure not to bend it
beyond a 

bend radius

 of 50 mm.

CAUTION!
