and connections
Battery compartment
Holds two 1.5v AA (LR6) type cells.
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.
Identification plug
Can be fitted with one of the coloured rubber plugs supplied
with the DX2040 to identify each unit.
Audio output
Provides transformer balanced microphone level and
adjustable headphone outputs.
Antenna A and Antenna B
SMA sockets to which the antennae are connected.
Indicators next to each antenna indicate which of the unit’s
two built-in receivers is active at any time.
Infra-red port
Receives commands from and transmits status information
back to the SwitchIR infra-red controller.
TX/DX low battery indicators
Illuminate when the unit detects low battery power in either
the TX2040 Pocket Transmitter or DX2040 Receiver. The
units should not be used when a low battery power indicator
is illuminated as poor operation may result.
Note: The low DX battery indicator does not function when
the receiver is externally powered via Audio Ltd’s cables.
This is not a fault.
No-signal indicator
Illuminated when no carrier signal is being received, such as
when the transmitter is switched off or set to an incorrect
frequency.
To set up the DX2040 in conjunction
with a TX2040 or HX2040:
•
Fit the batteries.
•
Connect the A and B antennae.
•
Connect the audio output cable.
•
Slide the On/Off switch to the On position.
•
Select the operating frequency.
•
Set the output level.
•
Check that one of the A and B indicators is illuminated
and that the red ‘No signal’ indicator is not illuminated.
These steps are explained on the following page:
