Choosing the Right SHIDU Voice Amplifier

Selecting a portable voice amplifier depends on more than output power.

Buyers should consider the following factors:

1. Required sound output

A compact 10W amplifier may be suitable for some smaller speaking environments, while larger or noisier venues may require a higher-output system.

2. Product weight

For users who frequently carry equipment, a 256g amplifier may be more convenient than a heavier portable speaker.

3. Microphone connection

The S40 is offered as a UHF wireless voice amplifier. Buyers should verify the microphone configuration and local wireless frequency requirements.

4. Playback requirements

Bluetooth, USB and TF card functions provide different ways to access instructional audio.
