Remoset u : this allows user to synchronize the transmitter after modifying a param-
eter. Push“ ” to synchronize the settings to the transmitter.
Remoset indicator : this shows the current pairing status. It ashes rapidly when
data is being transmitted and the ashing stops when the synchronization is com-
pleted. However, the ashing slows down if synchronization fails after a period of
time of pairing attempt.
Ultrasonic transmission unit: it transmits digital pairing data at ultrasonic frequency.
When setting, direct the ultrasonic receiving element of the microphone to the ultra-
sonic transmitting unit of the receivers. The eective range is 30º on both sides with
the optimized distance at 30cm.

5. Connecting
5-1 How to connect the receiver
1.1 ：
(1) The XLR output jack or 6.3mm unbalance output jack can be selected
individually to connect the AF output to a mixer or amplier for volume
control.
(2) Switch the “Mixed” on the back to ON. This allows to mix the RX1 and RX2
signals to RX1’s 6.3mm non-balance output jack and then to a mixer or
amplier for volume control.
1. Connect the audio output of receiver to mixer or amplier
2.1. Connect the AC/DC adapter:
Check that the DC current and voltage ratings of the adapter match the
label on the unit. Connect the DC terminal to the “DC input” port on the unit,
and the AC end to an AC socket.
2.2. Set the parameters:
Turn the power on and set the parameters of receiver according to the
setting instructions.
Caution! Secure the power cable on the fastening hook of anti-pulling clip in
order to prevent the power cable from falling.
