Azden 41XT, 411UDR, 41HT3, 41BT manual Power LED and on/off switch 411DRH only

Thank you for purchasing AZDEN’S “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 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 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 411DR’s Power LED will illuminate as soon as the unit is plugged in.

(2) Antenna A-B LED’s

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.
