illuminated.
These steps are explained below:
Mounting the receiver into the camera
To mount the CX iR receiver in the
wireless microphone receiver slot on
the camcorder:
•Remove the plate covering the
receiver slot on the camcorder.

User Guide CX iR Diversity Receiver
The CX iR is a multi-frequency UHF diversity receiver, designed with a range of modular adapters
to allow it to be mounted internally in the latest camcorders from Sony, Philips, and Ikegami.
Alternatively, a universal adapter fitted with the sixpin Lemo socket is available allowing the CX iR to
be used externally with camcorders that do not provide a built-in wireless microphone receiver slot.
Also,the CX iR can be used as a portable documentary or ENG receiver. All settings can be read or
changed via infra-red control using the Switch iR .

User Guide CX iR Diversity Receiver

The transmitter status is shown as one of the following
options:
Option Description
H (high) Indicates good.
L (low) Indicates low. Replace as soon as possible.
F (failed) Transmitter will not function correctly.
Indicators during operation
The CX iR should switch between the RX1 and RX2 receivers
for best reception, as indicated by the yellow RX1 and RX2
indicators on the top of the unit.
The red No Signal indicator will be lit if the corresponding
TX iR transmitter is not switched on, or is set to the incorrect
frequency.
The amber Low TX Battery indicator will be lit if the TX
battery goes low.
External powering
A number of different cables and accessories are available
from Audio Limited to allow the CX iR receiver to be externally
powered.
The maximum external DC supply must not exceed 18V.
Exceeding this voltage will result in damage to the receiver.
Audio Limited recommend the use of their regulated cables
to prevent damage to the CX iR .
Mounting options
The CX iR can be supplied already fitted with the appropriate
adapter for a specific camcorder. Alternatively it can be
supplied with a Lemo adapter for applications where the
CX iR is to be used with a mixer, or a camcorder without
an integral wireless microphone receiver slot. In this case
the receiver can be mounted onto the camera with an
appropriate bracket available from Audio Limited.
Adapters are available separately to allow you to modify
a CX iR for use with a different camcorder. To change the
adapter unscrew the four screws on the side of the unit at
the base with a slotted screwdriver. Slide out the adapter
and replace it with the appropriate replacement adapter: Do
not remove the screws at the base of the unit.
