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 amplifier (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.

5-2 Battery Insertion Of The Transmitter

(1) Press Down the battery lid and slide it out.

12

(2) Insert or replace with a new battery according to the polarity indication.
(3) Switch the ON/MUTE/OFF switch to ON. If the battery is in good

condition the LED indicator will light in Green constantly. As soon as

2

3

the battery goes below a preset level the LED indicator will turn to Red
constantly. Then the remaining battery life will last for 30 minutes only.

(4) Slide and push back the battery lid.

5-3 Install the transmitter

(1) Use the UT-16GT+6.3GT plug for guitar application

1. Insert the plug to the transmitter and turn it to the end.

2. Plug the transmitter into the instrument to be used.

3. Push down the transmitter towards the instrument. The step positioning
mechanism will hold the transmitter firmly on the instrument.

4. For traditional Gibson style end-mount input a sucker holder is provided
to prevent swiveling of the transmitter.

(2) Use the UT-16GTP for guitar application

1. Plug the transmitter into the instrument to be used.

2. Push down the transmitter towards the instrument. The step positioning
mechanism will hold the transmitter firmly on the instrument.

3. For traditional Gibson style end-mount input a sucker holder is provided
to prevent swiveling of the transmitter.

(2) Use the 516GT/508GT microphone module for accordion/winds/brass application

1 Insert the 516GT/508GT to the transmitter and turn it to the end.
2 Slide the 16GT Adapter/16GT CLIP/CLP-UT
into the transmitter and push it to the end.
3 Fix the 16GT Adapter + 516 Bracket to the accondion by
double-sided adhesive tape.
4 Fix the 16GT CLIP / CLP-UT to the instrument.
5 Adjust the 516GT/508GT to a position for desired sound performance.

(3) Setting Levels

1. Set a common frequency for both the receiver and transmitter by turning
the Channel Selector with supplied screw driver.

2. Turn the input gain control on the transmitter to a position halfway
between the left and right stops.

3. Set the ON/MUTE/OFF switch to ON to switch on transmitter.

4. Switch on the receiver and sound system.

5. Turn the volume control on the transmitter to maximum level (clockwise)
and play a few notes.

6. If the instrument sounds distorted turn down (count clockwise) the Input

5

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.

4

Be sure to mute the audio signal of a mixer or amplifier before turning on the
receiver and transmitter.
(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

3

It is always a good idea to keep “open space” between transmitter and
receiver, that will improve RF reception.

(2) Selecting channel for the receiver and transmitter

1. Use the supplied screwdriver to select a desired channel for the receiver
and transmitters . Both receiver and transmitters are preprogrammed with

4

16 channels.

2. Make sure the channel of receiver matches that of the transmitter.

3. When 2 or more system are being used in the same location, they must be
set up to use different 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 bottom of receiver and rack adaptor for inserting
screws.

(3) Single receiver

Insert in a receiver through the front of DR-900 until it is firmly attached
to the rack, then screw on a RP-900 to another side of the rack.

(4) Dual receivers

The 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 transmitter.

(2) Keep the devices away from the metal objects or any interference sources at

least 50 cm.

(3) To avoid the feed-back effect, don’t leave the mic. to aim at the speakers

directly.

(4) Remove batteries from the battery compartment when the transmitter will

not be used for a long time.
