DX 2020 Receiver

The DX 2020 diversity receiver in the RMS 2020

range can be used, in conjunction with a TX 2020 or

HX 2000 transmitter. Alternatively, up to four DX 2020

receivers can be rack mounted for applications

where multiple wireless microphone systems are

required.

RX1/RX2 indicators

Indicate which of the unit’s two built-in receivers is

active at any time.

TX/RX low battery indicators

Illuminate when the unit detects low battery power in

either the TX 2020 Pocket Transmitter or DX 2020

Receiver. The units should not be used when a low

battery power indicator is illuminated as poor operation

may result.

No-signal indicators

Illuminated when no carrier signal is being received,

such as when the transmitter is switched off or set to an

incorrect frequency.

On/Off

Switches the power on or off. Additionally the output

cable includes a link which disconnects power when

the Lemo plug is removed, in which case the switch can

be left on.
