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 511DRH receivers and the 51BT, 51XT and 51HT transmitters. Receiver Descriptions: The 411UDR and 511DRH are crystal controlled, PLL synthesized receivers with 63 on-board user selectable frequencies

(5) 12 Volt Input Plug the supplied AC adapter into the 12 volt input on the receiver then into an AC electrical outlet. Use only the adapter supplied, as other adapters may damage the receiver. (6) Output Adjustment Rotate this knob clockwise to increase, or counterclockwise to decrease volume level. (7) Output (unbalanced) Using a suitable audio cable (not supplied) connect the 1/4-inch phone jack end to the audio output on the receiver, and connect the other end of the cable to the suitable

HR-2 The following feature is for the 511DRH only. (12) Squelch adjust This adjusts the point at which the receiver will shut off or “squelch” the incoming radio signal when it becomes too weak. Turning the control clockwise raises the threshold, allowing more signal to enter, and turning the control counterclockwise lowers the threshold, letting in less signal. When operating multiple systems all receivers and transmitters must be on the same group Example: 4 systems operating simultaneously.

(6) LED INDICATORS The POWER LED turns green when power is turned “On” or red if battery level is low. If this LED lights up red replace the battery. The AF PEAK LED lights up if the input level is set to high, indicating the onset of distortion. Lower the input level so that the AF PEAK LED lights only occasionally. To plug the 51XT onto a microphone (low impedance with XRL connector) first make certain the locking-ring is turned fully up (rotate counterclockwise). Then plug the 51XT fully in

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 transmitter. 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 mi
