SHIDU Voice amplifiers

Overview

SHIDU voice amplifiers are compact, portable solutions designed to project your voice clearly and reduce vocal strain. Ideal for anyone who struggle to project their voice, especially in noisy or open environments. Models are available in both wired (headset connection) and wireless (Bluetooth or UHF microphone) versions.

Getting started

1. Connect the supplied USB charging cable to the amplifier (and headset on the wireless version).

2. Charge fully before first use (approx. 3–4 hours).

3. Indicator light will show charging status.

• Wired model: Plug in the headset mic, then switch on the power button.

• Wireless model: Switch on both the amplifier and the wireless microphone, ensuring they are paired.

• Use the waistband or belt clip to secure the unit around your waist or shoulder.

• Adjust the microphone to sit 2–3cm from the corner of your mouth.

• Avoid placing the microphone directly in front of your mouth to reduce feedback noise.

Pairing the wireless headset with the amplifier:

1. Turn on the headset microphone
2. Turn on the amplifier/speaker.
3. Press the M button on top of
   the amplifier until you hear “UHF mode”
4. Hold the M button for three
   seconds until you hear “UHF is waiting for a connection”
5. Now hold the pairing button down on the top of the headset microphone (the button is labelled with a wi-fi signal symbol) for five seconds
6. You should now hear “UHF is connected”
7. Speaking into the microphone should now be amplified through the speaker.
