Important Cautions
■ Always makes all connections before plugging the unit into an AC power outlet.
■ Do not leave the device in a place neither with high temperature nor high humidity.
■ Always do not handle the power cord with wet hands!
■ Keep the devices away from re and heat sources.
Features
■ Operated in UHF band where there is less RF interference than the VHF band.
■ Due to the PLL synthesized technology, the system oer 16 selectable channel.
■ e true diversity reception with 2 independent RF receivers ensure the stable transmission
and reception.
■ Adjustable squelch control can eectively reduce the noise.
■ Tuned antennas can benet the stable RF reception.
■ Built-in Tone key Squelch & Noise Mute detection are available to restrain the interference
signal.
■ Rugged metal housing can pass through the dicult environment.
■ Equipped with balanced XLR and unbalanced output allows great convenience.
■ Body-pack transmier provides phantom powering for condenser lavaliere and headset
microphones.

Preparing procedures & basic operation
5-1 Receiver
(1) Audio Output Connector
e receiver equipped with both balanced XLR output and unbalanced ∅6.3mm
jack output; you can choose the proper way for using.
Connect one end of the AF output cable to the AF output socket in the rear panel of
receiver and plug another end to the “MIC IN” input socket of a mixer or amplier.
(Step 1 of Figure 1)
(2) Power output connector
Connect one end of AC/DC adaptor cable to DC input socket in the rear panel of
receiver, and plug another end into an AC outlet. (Step 2 of Figure 1)
5
(Figure 1)

5-2 Battery Insertion of the transmitter
(1) Mh-850 & Mh-750 Handheld Transmier
1. Turn the microphone ball grille counter-clockwise (Step 1 of Figure 2), press
both release knobs to remove the baery tray from the mic. housing (Step 2 of
Figure 2).
2. Insert two 1.5V baeries according to the correct polarity, and return the baery
tray back to housing (Step 3 of Figure 3). Aim the connecting pins exactly
toward the cavities on the boom side of detachable mic. capsule module (Step 4
of Figure 3), and tighten it clockwise!
(Figure 2)
(Figure 3)

(2) Mh-8016 Handheld Transmier
Insert 2 pcs 1.5V AA baeries into the baery tray. (Figure 1)
Aer puing into the baery, switch on the power switch. (Figure 2)
(3) PT-850B / PT-850Bmi Body-pack Transmier
Slide the baery tray cover in the direction of the arrow to open it. Insert two 1.5V
baeries according to the correct polarity, and return the cover.(Figure 3)

5-3 Rack Mounting
(1) Before mount receivers onto DR-900 rack adaptor, please release any cables from
the rear of the receiver.
(2) Turn over receiver and DR-900 rack adaptor simultaneously, there are 4 threaded
holes each in the boom of receiver and rack adaptor for inserting screws.
(3) Single receiver
Insert in a receiver through the front of DR-900 until it is rmly aached to the
rack, then screw on a RP-900 to another side of the rack. (Figure 4)
(4) Dual receivers
e same way as above, put one
receiver to each rack space.
(Figure 4)
17 DUAL CHANNEL PLL DIVERSITY WIRELESS SYSTEM
5-4 Installation of condenser microphones
(1) Lavalier microphone
Aach a laveliere microphone to , tie, lapel, where is suitable for sound pick-up. Plug
the connector into input socket on the body-pack transmier. (Figure 1)
(2) Headset microphone
Put the headband behind your head, and x the temples on your ears as (Figure 2)
shows, then adjust the gooseneck to have best miking. Plug the connector into
input socket on the body-pack transmier. (Figure 2)
