This professional series wireless micro phone system used an efficient American,
Iow consumption discharging technique with a super sensitive UHF high broadband
frequency receiver and controlled with 10ppm crystal, matched with an independent
developed mobile frequency compression, expander circuit, image frequency limiting
circuit, a multiple checked silent and noisy circuit, switch impact noise defect circuit,
resist reverberation circuit and changed output controlled slowly...ect, And designed
by a computer EDA system and finished on its item named pattern line .Every
system is available to an excellent electric function by Q.C. strictly.

INTRODUCTION

Your new wireless Series system is designed to give you the best of both sound
reinforcement worlds: the freedom of a wireless system, and the excellent quality.
This manual covers each of the Series system : The Vocal Artist-UHF , The Presenter-
UHF, The headset-UHF and The Guitarist-UHF.

SYSTEM FEATURES

All UHF Series systems offer a variety of exceptional features, including:
1. Simultaneous Output Use: Unbalanced 1/4' phone plug and balanced XLR output
connectors may be used simultaneously to different external devices.
2. Range: UHFSeries transmitters will work at a distance of up to 50 meters(about
164 ft.) from the receiver.
3. Noise Squelch: Squelch circuit analyzes signal strength and quality so that can
reduces the likelihood of noise burst due to environmental RF (radio frequency) noise.
4. Low Battery Waming Light: A red light on the body-pack and hand -held transmitters
warns the user that there is less than one hour of battery life left.

SYSTEM TYPE

The Vocal Artist-UHF is a hand-held system designed for singers who desire the
high quality of microphones and the freedom of wireless performance.
The Presenter-UHF is a body-pack system designed for public speakers who prefer
an inconspicuous, hands-free lavalier microphone.
The Headset-UHF is a body-pack system designed for users in physically active
applications, who desire the freedom of hand-free microphone.
The Guitarist-UHF is a body-pack system designed for use with electric guitars,
basses, and other electric instruments.
