the best performance from your purchase. We also recommend that you keep this manual handy for future reference.
VHF series professional wireless microphone systems introduces a number of advanced techniques and components,
including the ecient low consumption RF transmission, impact elimination, slow controlled output, superiors
sensitivity VHF narrow band HF and MF lters and 15ppm Crystal Frequency Lock etc. Online simulation EDA and strict
quality control are applied to ensure each system with excellent function.
FEATURES:
• Introducing a special ALC circuit to ensure nondistortion;
• Frequency compressing expanding technique to lower the noise and enlarge the dynamic range.
• Superior squelch and high signal to noise ratio.
• Almost zero noise output when standby.
• Broad frequency response range, super low distortion.
• Perfect operation status indications.
• Multiple HF and MF narrow band lters to eliminate interfering signal.
• Introducing low power consumption components to ensure longer battery life.
• Special impact wave eliminating circuit for handheld microphone switches.
• Long practical distance. Over 80m in ideal circumstances; practical 20 m radius in complex circumstances.
• Multiple frequency design. Be able to use two microphones at the same time without mutual interference;
• Applicable for medium & small stages, karaoke halls, and home entertainment etc.

SYSTEM SETUP
1. Plug the provided audio cable into the receiver's MIX output connector, and the other end into a mixer or power
amplier system. Extend the two antennas fully to the vertical position. Switch ON the receiver, the POWER ON light
will glow indicating the machine standby. (Better keep distance between the receiver and oor to ensure good
receiving signals).
2. Open the battery cover of the microphone and install the batteries inside the compartment properly, then re-attach
the battery cover.
3. Position the transmitter power switch to ON, indicator light will glow (MUTE position).
Now the receiver's corresponding channel light will also glow, indicating that the receiver has already received the
eective signals from the transmitter. Adjust volume knobs of the receiver and power amplier to ensure the suitable
volume for the system. Speak with microphone to check the sound.
4. When the transmitter power indicator dardens, it indicates low battery power.
Please change with new batteries in time. (Note: Do Not Mix Old and New Batteries)
5. When using multiple system at the same time, it is necessary to use machines of dierent frequency.
System Turn On Process: Receiver Mixer or Pre Amplier Power Amplier (Opposite when Turned OFF)
