Installing/Servicing the Airlab

NOTE:

Wiring a tuner needs special attention. If the tuner is "cabled", the coax antennae cable will

probably cause a ground loop. A H.F. transformer must separate the antenna input of the tuner.

Ask your dealer or any radio shop for details.

*IMPORTANT*

SAFETY PRECAUTION - All 'outside' connections to the Airlab, even from the same building, must be

connected via a transformer. This avoids the possibility of ground loops and 'hums'. The shielding must be

connected to the source side.

In areas with a strong H.F. interference, it is wise to connect the other side of the shielding through a 0.1

uF/250 Volt ceramic capacitor. The capacitor will not affect the audio, but will reduce H.F. signals.

Servicing the Airlab

A. Disconnect the mains supply.

B. Remove the power cable from the back of the console.

C. Remove the back panel of the meter hood.

D. Unscrew the channel module bolts.

E. Now lift the channel up at the fader section, and then the other side. Carefully lift

the module until you see three connectors mounted to ribbon (flat) cables.

F. On the PCB part of the connector you will see two ejectors with which to eject the

cable header.

Installing the Channel Module

A. Plug the three ribbon cable connectors into the PCB connector, ensuring that the

ejectors are securely replaced.

B. Slowly put the module down into the chassis starting from the rear.

C. Tighten all screws and reconnect the channel.

Servicing the Master Section

A. Disconnect the Airlab from the mains supply.

B. Remove all holding screws.

C. Lift the master section starting from the fader's side.

D. Remove the connector to the power PCB.

E. Lift the section upwards until you are able to remove the ribbon cable from the PCBs.

F. Reverse this procedure to re-mount the master section.
