Azden 411DRH Receiver and 51HT Handheld Microphone UHF Wireless System
A complete UHF hand held system consisting of the 411DRH 63-channel receiver and the 51HT handheld mic/transmitter.
The Azden 411 series provides affordable UHF wireless microphone systems ideal for small theater, clubs, restaurants, lectures etc.

The 51HT Handheld microphone transmitter with 63 on-board user selectable UHF frequencies. Ideal for all vocal applications.
The 411UDR and 411DRH are crystal controlled, PLL synthesized receivers with 63
on-board user selectable frequencies with a range of 794MHz to approx. 806MHz. They are 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.
Both receivers feature a 1/4-inch and XLR output jacks and volume adjustment.
