The DX2040 true diversity receiver in the RMS2040 range can be used with the TX2040 pocket transmitter and the HX2040 handheld transmitter. It is also fully compatible with the TX2020 and TX2000 UHF transmitters. All settings on the DX2040 receiver can be read or changed via infra-red using the SwitchiR or AudiR© for Palm™. miniTX ........................ The miniTX transmitter is the smallest transmitter in the Audio Ltd range. Designed as a rounded form to be very easily concealed. All settings can be set and changed via the infra-red port using the SwitchiR™, and the miniTX can also be turned on and off through clothing using the Control-X. There are two versions of the transmitter available: one with a 4-pin Lemo connector and the other with a 3-pin Lemo connector. TX2040 ........................ The TX2040 is a pocket transmitter that provides 32 pre- programmed frequencies with a switching bandwidth of up to 24MHz. The transmitter can be switched on and off, even when it is worn beneath clothing, using the unique Control-X handset. It is also compatible with the SwitchiR infra-red controller, and AudiR™ application Palm PDA. HX2040 ........................ The HX2040 is a handheld transmitter designed in a classical conical shape, designed to accept any of 14 condenser capsules from the Schoeps™ Colette range. The transmitter has 32 pre-programmed frequencies with up to 24MHz switching bandwidth, and it includes a unique infra-red remote control interface for reliable and accessible control over settings via the SwitchiR or AudiR™ application for Palm PDAs. Introduction The 2040 range has been designed as a result of extensive feedback from professional sound specialists and sets a new benchmark for radio microphone systems, with several unique features and offering benefits to appeal to sound mixers, directors, and artists. CHAPTER 1  2 SwitchiR ........................ The SwitchiR is an infra-red remote control unit the size of a key fob, which can be used to access all the user-settable functions of the TX2040 and HX2040. Functions include transmitter frequency, audio level, battery status, serial number, and user identification. Control-X ........................ The Control-X uses electromagnetic induction to allow the miniTX or TX2040 transmitter to be controlled remotely, even through clothing. At a distance of up to 20cm (8") the Control-X can switch on and off the transmitter, or check and display the selected frequency, and it also provides battery check features. RK2040 ........................ The RK2040 is a compact 1U rack capable of accommodating up to four true diversity receivers. The RK2040 can be mains powered via an AC/DC adaptor, or can be powered from any 10-18V DC source. A built-in RS485 PC interface allows remote monitoring and control via Audio Ltd’s PC-based monitoring application, Racktop.   CHAPTER 2 Controls, display and connections ........................ Bottom panel Battery compartment Identification plug On/off switch 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. Top panel Antenna A No signal Audio output Antenna B Infra-red port TX low battery DX low battery 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. DX2040 Receiver The DX2040 true diversity receiver in the RMS2040 range can be used with the TX2040 pocket transmitter and the HX2040 handheld transmitter. It is also fully compatible with the TX2020 and TX2000 UHF transmitters. All settings on the DX2040 receiver can be read or changed via infra-red using the SwitchiR or AudiR© for Palm™. DX2040 Receiver  4 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. Setting up the DX2040 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 below: Fitting the batteries To open the battery compartment, slide the release catch towards the centre of the DX2040 and flip open the cap. Insert two 1.5 volt AA (LR6) type batteries, negative contact first as shown on the side of the unit, and close the cover. Do not use excessive force. Connecting the antennae Connect the antennae to the SMA connectors marked Antenna A and Antenna B. Connect the straight antenna to one socket and the right-angled antenna to the other socket. Selecting the oper…
