The 500XT is a complete system which includes the 51XT wireless XLR plug-in UHF transmitter and the 500UDR receiver.

The 500UDR Enhanced Performance UHF Wireless Receiver represents a breakthrough in on-camera, frequency-selectable UHF receivers. Its 'Enhanced Performance' assures you of the highest image rejection combined with the finest in audio clarity. The crystal-controlled, PLL-synthesized mixer/local oscillator provides for extremely accurate frequency selection while the twin-antenna true diversity dual front-end reduces multipath distortion caused dropouts to near zero.

In the real world of ENG the ability to be able to select a 'clear' frequency on the spot is vitally important. Going out into the field with a single-frequency unit invites disaster since there is no way of knowing what frequencies will be used by the other crews that are covering the same story. Think of your 500UDR as your insurance policy -- your assurance of getting the story.

Designed by professionals - for professionals, the 500UDR will provide you with years of worry-free, high-quality performance and will work flawlessly with the Azden 51XT frequency-agile transmitter with 63 on-board user selectable UHF frequencies. The 51XT is a compact plug-in transmitter which converts low-impedance microphones to wireless. Using a special 'lock-down' XLR connector for a secure grip, the transmitter is powered for more than 8 hours by a single 9V Alkaline battery. Featured are a separate On/Off switch (with LED indicator), an Audio Standby switch as well as a microphone input level control with Peak indicator LED (allowing the adaptor to transmit the output of a soundboard as well). Additionally, the 51XT provides switched phantom power.

Azden 500UDR UHF Wireless Receiver

Azden 500UDR Key Features

63 User-Selectable Frequencies

The 500XT is a frequency agile system, meaning that you choose the frequency of both the transmitter and receiver via the group and channel controls. The group knob allows you to select any of seven frequency groups (numbered from 0-6). The channel knob allows you to select any of nine frequency channels (numbered from 0-8) within the selected group. This method of group/channel selection provides 63 possible choices (794-806Mhz).

Crystal-Controlled and PLL-Synthesized

The crystal-controlled, PLL-synthesized mixer/local oscillator provides for extremely accurate frequency selection.

Tone-Code Squelch

Switching the Audio to OFF on the microphone will cause the receiver to mute due to the tone squelch circuitry in the receiver. This allows the microphone to be handled with no noise.

Dual Antennas With BNC Connectors

A true diversity front end with twin removable antennas reduces multipath distortion caused dropouts to near zero.

XLR Output With Volume Control

Headphone Output With Volume Control

In-use monitoring is achieved through the provided ear phone jack which has a separate volume control.

Operates on 6 AA Batteries or 12V DC

Using 6 AA batteries, the 500UDR can operate for more than 8-1/2 hours. For even longer duty, the 500UDR can be powered by an external power source through its DC-IN jack.

LED Indicators

• A/B ANT - depending upon which antenna is receiving the stronger signal, the A or B ANT LED will glow green when both the transmitter and receiver are turned ON and adjusted to the same frequency. Occasional rapid changing of the two LEDs is a normal indication of the diversity front-end working to reduce multipath distortion.
• AF PEAK - this indicator lights when the receiver's input level from the transmitter exceeds unity.
• POWER - with fresh batteries, this LED lights red when the power switch is turned ON. When the battery level drops to 4 volts this LED will flash on and off. When this happens it is time to replace the batteries.

Velcro Mount

The 500UDR easily attaches to the video camera with the supplied Velcro.

Azden 51XT Wireless XLR Plug-in Transmitter

Azden 51XT Key Features

Plug-in XLR Microphone Transmitter

Convert any XLR microphone into a wireless. Usng a special lockdown XLR connector for a secure grip on your mic, the 51XT is powered by a standard AA alkaline battery.

Input Level Control

The audio input level control enables you to adjust the input level of the microphone. Turn clockwise to increase, or counter-clockwise to decrease the input level. A small screwdriver is supplied to make these adjustments.

Power and Audio Switches

The power ON and OFF switch enables and disables all transmitter functions while the Audio switch ON and OFF turn just the transmitter's audio signal on and off. Switching the Audio to OFF will cause the receiver to mute due to the tone squelch circuitry at the receiver. This allows the microphone to be handled with no noise.
