1. Important Caution
2. Features
Always make all connections before plugging the unit into an AC power outlet. •
Do not leave the devices in a place neither with high temperature nor high humidity.•
Always do not handle the power cord with wet hands !•
Keep the devices away from re and heat sources. •
Operated in UHF band where there is less RF interference than the VHF band. •
Due to the PLL synthesized technology, the system can oer up to 193 selectable frequencies for •
choosing simultaneously.
e true diversity reception with 2 independent RF receivers ensure the stable transmission and •
reception.
Adjustable Pilot tone squelch control can eectively reduce the noise. •
Equipped with S.A.W. lter benets the interference-resistant. •
Tuned antennas can benet the stable RF reception.•
Built-in Noise Squelch circuity & Mute function are available to restrain the interference for •
signals.
Compact half-rack receiver design is considerable for the space saving.
•
Rugged metal housing can pass through the dicult environment. •
Equipped with balanced XLR and unbalanced output allow great convenience.•
Anti-interference design is available to work with every computer device.•
