1. Important Cautions

1-1 Always make all connections before plugging the unit into an AC power outlet.
1-2 Do not leave the devices in a place neither with high temperature nor high humidity.
1-3 Always do not handle the power cord with wet hands !
1-4 Keep the devices away from fire and heat sources.

2. Features

* Operated in UHF band where there is less RF interference than the VHF band.
* Due to the PLL synthesized technology, the system can offer up to 961 selectable
frequencies for choosing simultaneously.
* The true diversity reception with 2 independent RF receivers ensure the stable
transmission and reception.
* Adjustable Pilot tone squelch control can effectively reduce the noise.
* Equipped with S.A.W. filter benefits the interference-resistant.
* Tuned antennas can benefit 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 difficult environment.
* Equipped with balanced XLR and unbalanced output allow great convenience.
* Anti-interference design is available to work with every computer device.
