The 511LSH is a complete system which includes the 51BT body-pack transmitter, the Sony ECM-44H electret condenser lavalier microphone and the 511DRH half-rack receiver. It is identical to the Azden 511LTH 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.

Housed in a metal half-rack sized enclosure, the AC-powered 511DRH receiver with improved circuitry replaces the 411DRH. The 511DRH and is a crystal controlled, PLL synthesized receiver with 63 on-board user selectable UHF frequencies with a range of 794MHz to approx. 806MHz. It is true diversity, containing two separate receivers, each operating on the same frequency. The transmitter's output signal is monitored constantly by a diversity circuit, which switches automatically to the receiver with the stronger RF signal. This allows wireless performance that is virtually drop-out free, even under the most adverse conditions. The 511DRH can be rack mounted with the optional HR1 or HR2 kits. The HR1 will rack mount a single 511DRH receiver, while the HR2 will mount two.

The 511DRH 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 511DRH Key Features

63 User-Selectable Frequencies

The 511DRH 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.

Twin LED Indicators for Antenna Reception and Signal Strength

When the transmitter is turned on and is in reception range of the receiver, either the A or B LED will light up RED, depending on which receiver circuit is getting the strongest signal from the transmitter. Flickering between the A and B LED is a normal indication of the diversity front-end working to reduce multipath distortion. A 5-step LED array is provided for easy monitoring of signal strangth.

Five-Step Audio Level LED Array With Peak LED Indicator

This indicator lights when the receiver's input level from the transmitter exceeds unity.

Channel Selection Knobs and and Power On/Off on Front Panel

Removeable Dual Antennas With BNC Connectors

A true diversity front end with twin antennas reduces multipath distortion caused dropouts to near zero. The supplied antennas are connector mounted (BNC) so that they can be disconnected and/or removed. The BNC antenna connectors are located on the rear panel.

12V DC Input

Plug the supplied AC adapter into the 12 volt input on the receiver then into an AC electrical outlet.

Output Adjustment

Rotate this knob clockwise to increase, or counterclockwise to decrease volume level. Located on the rear panel.

Balanced and Unbalanced Output

The 511DRH features both 1/4-inch and XLR output jacks located on the rear panel.

Variable 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.

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.
