The 411HT is a complete system which includes the 51HT wireless handheld microphone/UHF transmitter and the 411UDR receiver.

The 411UDR 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 411UDR features both 1/4-inch and XLR output jacks and volume adjustment, and can be rack mounted with the 321RK kit. Up to 9 systems may be used simultaneously. An AC Adapter is included with the 411UDR.

The 411UDR 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 411UDR UHF Wireless Receiver

Azden 411UDR Key Features

63 User-Selectable Frequencies

The 411HT 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.

Antenna A/B LED Indicators

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.

Peak LED Indicator

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

Power LED Indicator

The 411UDR's Power LED will illuminate as soon as the unit is plugged in.

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.

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.

Balanced and Unbalanced Output

The 411UDR features both 1/4-inch and XLR output jacks and volume adjustment.

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.
