WB-200 SERIES INTERCOM SYSTEM — WBS-200 DUAL CHANNEL WIRELESS BASE STATION

PROGRAM INPUT TRANSFORMER (IT-DA)

In order to improve the input common mode rejection ratio and for a galvanic isolation with

the previous part of the audio system, an input transformer is available.

The program input has an insert point for the input transformer (TR2) placed just beside the

XLR-3-31 program input connector, in the rear right corner of the main PCB.

Before placing the transformer, you should remove the two links

corresponding to the program input transformer (LK3 and LK4).

In the following picture is shown the placement of the input

transformer TR2. It is important to keep in mind the placement of the

input transformer pins to make it coincide with the main PCB (four

behind and three forward).

Remove the links corresponding to the program input transformer

(LK3 and LK4).

Place the input transformer, keeping in mind the position of their

pins (four behind and three forward), and solder it to the main PCB.

OUTPUT TRANSFORMER (OT-DA)

In order to make a galvanic isolation with the next part of the audio system, an output

transformer is available.

The PA output has an insert point for the output transformer (TR1) placed just beside the XLR-

3-32 pa output connector, in the rear right corner of the main PCB.

The following picture is showing the placement of the output transformer TR1. It is important

to keep in mind the placement of the output transformer pins to make it coincide with the main

PCB (seven behind and six forward).

Before placing the transformer, you should remove the two links corresponding to the pa

output transformer (LK1 and LK2).

Remove the links corresponding to the output transformer LK1

and LK2.

Place the output transformer, keeping in mind the position of

their pins (seven behind and six forward), and solder it to the main

PCB.
