VT9
Practical Wireless System
The VT9 Series wireless system is built for karaoke and general PA applications. This system has been carefully designed to ensure that a clear and warm vocal will be reproduced and has a highly steady wirless system within effective operating distance. This series is the most popular for installation in karaoke boxes, school teaching, speech, and night club applications.

Features
General Features
• Quartz oscillation fixed frequency Receiver, no need to match the channel
• Frequency range: 170 MHz-250 MHz
• HF with multiple narrow-band and MF with selected filter to minimize the interference of hash
• Low voltage working design, battery powered handheld transmitter works even when voltage is lowered to 5V
• ALC circuitry protects microphone from high sound pressure, low distortion
• Eliminate unwanted pulse noise design while turning ON or OFF transmiter
• Quartz oscillation mode to ensure ultra-stability
• Advance compander circuitry reduces noise and increases dynamic range
• Feedback eliminator to increase the maximum feedback level
• Independent output and mixed output
Application
• Family Karaoke
• PA
