The 511HTH is a complete system which includes the 51HT wireless handheld microphone/UHF transmitter and the 511DRH half-rack receiver.

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 51HT frequency-agile transmitter with 63 on-board user selectable UHF frequencies. The 51HT is a wireless handheld microphone/UHF transmitter ideal for vocal applications.

Azden 511DRH UHF Wireless Receiver

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 51HT Handheld Microphone/Wireless UHF Transmitter

Azden 51HT Key Features

Ideal For Vocal Applications

This rugged metal body handheld features a supercardioid unidirectional microphone element. The transmitter is built into the mike housing and the antenna screws into the base, therefore requiring no dangling wires.

2-Position Power Switch

The power ON and OFF switch enables and disables all transmitter functions. Turning the transmitter OFF will cause the receiver to mute due to the tone squelch circuitry at the receiver. This allows the mic to be handled with no noise.

Screw-In Antenna

The antenna attaches to the bottom of the microphone.

63 User-Selectable Frequencies

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).

LED Indicator

The LED Indicator turns green when turned on. This LED will also turn red to indicate that the battery level is low and the batteries must be changed.
