Introduction - Azden 500UDR User Manual

51BT with Lavaliere or Headset:
With someone talking into the microphone, turn the volume on the mixer or amplifier
to the desired level. If there is too much, or not enough gain, lower or raise the
volume on the receiver. If the sound is distorted, lower the input gain on the transmit-
ter.
51BT with Instrument cable for electric guitars or basses (MP-1H):
Plug the cable into the guitar or bass. Set the instrument volume to the midway point.
While playing the instrument, turn the volume on the mixer or amplifier to the desired
level. If there is too much, or not enough gain, lower or raise the volume on the
receiver. If the sound is distorted, lower the input gain (6) on the transmitter.
51XT: With someone talking into the microphone, turn the volume on the mixer or
amplifier to the desired level. If there is too much, or not enough gain, lower or raise
the volume on the receiver. If the sound is distorted, lower the input gain on the
transmitter.
51HT:
With someone talking/singing into the microphone, turn the volume on the mixer/
amplifier to the desired level. If there is too much, or too little gain, adjust the volume
on the receiver. If the sound is distorted, move the microphone further away from the
sound source. Make sure that the LED is green when the mic/transmitter is turned
On. When the battery is low, the LED turns red indicating that the battery needs to be
changed.

INTRODUCTION

Thank you for selecting the Azden 500UDR as your portable/on-camera UHF receiver. We
are confident that it will perform beyond your expectations. For over 40 years Azden Corpo-
ration has been creating technologically advanced products. By taking advantage of the
latest in CAD design and SMT production techniques, Azden's engineers are able to pro-
duce products that exceed the published specifications and perform well beyond the war-
ranty period.
The 500UDR represents a breakthrough in on-camera, frequency-selectable UHF receiv-
ers. Its 'Enhanced Performance' assures you of the highest image rejection combined with
the finest in audio clarity. The crystal-controlled, PLL-synthesized mixer/local oscillator pro-
vides for extremely accurate frequency selection while the twin-antenna true diversity dual
front-end reduces multipath distortion caused dropouts to near zero.
In the real world of ENG the ability to be able to select a 'clear' frequency on the spot is vitally
important. Going out into the field with a single-frequency unit invites disaster since there is
no way of knowing what frequencies will be used by the other crews that are covering the
same story. Think of your 500UDR as your insurance policy - your assurance of getting the
story.
Designed by professionals - for professionals, the 500UDR will provide you with years of
worry-free, high-quality performance and will work flawlessly with the Azden 51BT, 51HT
and 51XT frequency-agile UHF transmitters.
