Thank you for purchasing AZDENS PERFORMANCE SERIES wireless system. UHF wireless
systems yield a better signal to noise ratio and improved frequency response over VHF systems. The
UHF band is less crowded than VHF thus giving you less likelihood of interference. This manual covers
the 411UDR and 411DRH receivers and the 41BT, 41XT and 41HT transmitters.
Receiver Descriptions: 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 transmitters 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 condi-
tions. Both receivers feature a 1/4-inch and XLR output jacks and volume adjustment.
(1) Power LED and on/off switch (411DRH only)
After plugging in the 411DRH, depress the on/off switch to turn unit on and illuminate the Power LED.
The 411DRs Power LED will illuminate as soon as the unit is plugged in.
(2) Antenna A-B LEDs
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 function of the system.
(3) Peak LED
These will flash if the audio component of the incoming signal is approaching distortion. The 411DRH has a 7
segment LED display to show the incoming audio signal from -20 to + 6 dB.
(4) Antennas, antenna connections
On both the 411UDR and 411DRH, position the antennas vertically for best reception. On the 411UDR, when
not in use put the antennas in the holder to avoid damage. On the 411DRH the antennas are connector
mounted (BNC) so that the supplied antennas can be disconnected and/or removed.
