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 either with high temperature or 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 oer up to 961 selectable frequencies
togther with preset 4 groups each of 16 channels.
• The true diversity reception with 2 independent RF receivers ensure the stable reception.
• Adjustable Pilot tone squelch control can eectively reduce the noise.
• Equipped with S.A.W. lter benets the interference-resistant.
• Tuned antennas can benet the stable RF reception.
• Built-in Noise Squelch circuity & Mute function are available to restrain the interference for
signals.
• Compact half-rack receiver design for space saving.
• Rugged metal housing can withstand rough environment.
• Equipped with balanced XLR and unbalanced output allow great convenience.
• Anti-interference design is available to work with every computer device.
