5. Preparing Procedures & Basic Operation
5-1 Receiver
(1) Connect to the subsequent unit (e.g. mixer, or amplifier)
Connect one end of a proper AF cable to the AF Output or Balanced XLR Output socket, then plug
another end to the “MIC IN” input socket of a mixer or a amplier (Step 1)
(2) Connect the power supply unit
Plug in one end of AC/DC adaptor cable to Power Supply Jack in the rear panel of receiver, and plug
another end into an AC outlet (Step 2)
Caution
To prevent accidental disconnection of the plug from the jack, lead the cable around the hook of the strain
relief.

(1) Press Down the baery lid and slide it out.
(2) Insert or replace with a new baery according to the polarity indication.
(3) Switch the ON/MUTE/OFF switch to ON. If the baery is in good
condition the LED indicator will light in Green constantly. As soon as
the baery goes below a preset level the LED indicator will turn to Red
constantly. en the remaining baery life will last for 30 minutes only.
(4) Slide and push back the baery lid.

(1) Use the 6.3GT plug for guitar application
1. Insert the plug to the transmier and turn it to the end.
2. Plug the transmier into the instrument to be used.
3. Push down the transmier towards the instrument. e step positioning
mechanism will hold the transmier rmly on the instrument.
4. For traditional Gibson style end-mount input a sucker holder is
provided to prevent swiveling of the transmier.
(2) Use the 508GT microphone module for winds application
1. Insert the 508GT to the transmier and turn it to the end.
2. Slide the clip into the transmier and push it to the end.
3. Fix the clip to the instrument by turning the screw clockwise.
4. Adjust the 508GT to a position for desired sound performance.

(3) Setting Levels
1. Set a common frequency for both the receiver and transmier by turning the Channel Selector
with supplied screw driver.
2. Turn the input gain control on the transmier to a position halfway between the le and right
stops.
3. Set the ON/MUTE/OFF switch to ON to switch on transmier.
4. Switch on the receiver and sound system.
5. Turn the volume control on the instrument to maximum level (clockwise) and play a few notes.
6. If the instrument sounds distorted turn down (count clockwise) the Input Gain to a point
where no distortion is heard. If the instrument sounds too low, turn up (clockwise) the Input Gain
just before distortion is heard.

6. System Operation
Be sure to mute the audio signal of a mixer or amplier before turning on the receiver and transmier.
(1) Power on
Turn AF level on the receiver completely counter-clockwise to the minimum level, and switch on the
receiver. As soon as you turn power of the receiver on, the power LED lights red, meanwhile
the RF signal and AF LED light up to indicate the receiver is ready for operating.
Always it is a good idea to keep “open space” between transmier and receiver, that will improve RF
reception.
(2) Selecting channel for the receiver and transmier
1. Use the supplied screwdriver to select a desired channel for the receiver and transmiers .
Both receiver and transmiers are preprogrammed with 16 channels.
2. Make sure the channel of receiver matches that of the transmier.
3. When 2 or more transmiers and receivers are being used in the same location, they must be set up to
use dierent channels. If existing channel is being interfered, please change to another non-interference
channel.

7. 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 at the boom 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 aached to the rack, then screw on a RP-
900 to another side of the rack.
(4) Dual receivers
e same way as above, put one receiver to each rack space.

12
8. Recommendation
(1) In order to achieve the optimum reception condition and also extend the operating distance, please leave
on “open space” between the receiver and transmier.
(2) Keep the devices away from the metal objects or any interference sources at least 50 cm.
(3) To avoid the feed-back eect, don’t leave the mic. to aim at the speakers directly.
(4) Remove baeries from the baery compartment when the transmier will not be used for a long time.
