6. ACCESSORY OPTIONS

In this section we will explain the different available options for the base station WBS-200 unit.

PROGRAM INPUT TRANSFORMER (IT-DA)

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

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

The provided transformers fulfil the isolation rule of 1.5 kV.

PA OUTPUT TRANSFORMER (OT-DA)

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

transformer for the PA output is available.

The provided transformers fulfil the isolation rule of 2 kV.

DIRECTIONAL ANTENNA (DA-P6060)

This accessory is provided with an extension 2 meter low loses coaxial cable. The antenna

must be installed on the wall pointing out the desired area and covers a focused beam of 60

degres H by 60 degres V. The panel antenna must be installed on the unit to cover the local area

around the unit.

7. SPECIAL OPERATIONS

In order to set-up some of the master station possibilities, the unit must be opened removing

the six screws of the unit top cover, and for the input and output transformers placement also the six

screws of the unit bottom cover, to solder the transformers.

NOTE: This type of operations takes place with the unit is opened; the best thing should be to carry it

out by a qualified technician.

DANGER: Before opening the unit, disconnect it from the mains. It is important to indicate that

although the unit is switched off (with the power switch in 0 position), if it keeps being connected to

the mains there are different parts of the unit that are subjected to high voltage.

CAUTION: Protect the master station from the rain and moisture, mostly if it is open. If liquid is spilled

into the unit, disconnect it from the mains and consult a qualified service technician.
