The 500LTS is a complete system which includes the 51BT body-pack transmitter, the Sony ECM-44H lavalier microphone and the 500UDR receiver. It is identical to the Azden 500LT system, with the exception of the ECM-44H replacing the EX-503H microphone. One of the most popular all-purpose lavalier mics on the market, the Sony ECM-44H is an industry standard for professional video. It is an omni-directional microphone that produces clean, warm voice tones and somewhat suppresses excess background and wind noise.

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 51BT frequency-agile body-pack UHF transmitter with 63 on-board user selectable UHF frequencies. The 51BT is a body-pack transmitter ideal for use with lavaliere and headset microphones. The 51BT is housed in a sleek, modern case with a metal belt-clip. It features a brand-new antenna design for improved transmission as well as new circuitry for lower noise levels.

Azden 500UDR UHF Wireless Receiver

Azden 500UDR Key Features

63 User-Selectable Frequencies

The 500LTS 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 51BT UHF Wireless Body-Pack Transmitter

Azden 51BT Key Features

Compact and Unobtrusive Transmitter Unit With Metal Belt Clip

The 51BT transmitter comes with a belt clip. It is small enough to also be tucked into a jacket or pants pocket.

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. The level control is factory-preset in the center position.

Power and Standby Switches

The power ON and OFF switch enables and disables all transmitter functions while the audio switch ON and STANDBY turn the audio off and on. Switching the transmitter to STANDBY 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.
