SYSTEM CONNECTIONS

Receiver power connection: Connect the AC adapter into the DC power connector on the back of the receiver. Plug the AC adapter into a AC230V 50Hz outlet.
Antenna: Keep the position of antenna at a 45° angle from vertical. Shown as below.
Audio connection: Connect the audio cable from the audio output on the receiver to the input on your amplifier equipment.

OPERATION

Turn off the system first, turn down the receivers volume to the minimum and then turn on the receiver, CPU initializes, the LCD screen begins to display and the system reverts to the last shutdown’s state!

If the system is turned on look at the transmitter and receiver’s frequency. Then the receiver display shows RF signal level value, the antenna status will display antenna A or B. Adjust the volume to the desired level.

Volume adjustment
Adjust the receiver’s volume to the 12 o’clock position, then adjust the volume of the amplifier or mixer to a desired level. If the receiver volume has been adjusted too loud the amplifier will produce a saturated distortion which will blow the amplifier or/and the loudspeaker(s)!

Best acoustics:

You should always see the receiver antenna from your transmitter location.
The distance between transmitter and receiver should be as short as possible.
If the receiver has two antennas, they should be adjusted 45° with a vertical line.
Keep the antennas away from metal surfaces and shelter.
Let the antennas not contact or cross each other.
Before using the system during the presence of public do a test to find out where the “dead spots” are. Avoid these spots when operational
