Preparing Procedures

How to connect the receiver// RU-901Du

1. RU-901Du：
   (1) The XLR output jack or 6.3mm unbalance output jack can be selected individually to connect the AF output to a mixer or amplifier 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 amplifier for volume control.

2. Connect to powe
   2.1. Connect to AC outlet:
   One end connects to receiver “power input”, while the other end connects to AC power receptacle.
   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.

3. Cascading of AC power cable and antenna
   It is allowed to cascade power and antennas for 5 units.
