5. Preparing Procedures & Basic Operation
5-1 Receiver
(1) Audio Output Connector
Connect one end of the AF output cable to the AF output socket in the rear panel, then plug
another end to the “MIC IN” input socket of a mixer or amplier. (Step 1)
It is equipped with balanced XLR output and unbalanced Φ6.3mm output, choose the
proper way for use.
(2) Power output connector
Plug in one end of AC/DC adaptor cable to DC input socket in the rear panel of receiver, and
plug another end into an AC outlet. (Step 2)
(3) Turn the receiver on by pressing the Power buon on
the front panel
(4) Adjust the volume control to a proper level.
