SGPRO UHF wireless microphone system SG-400

Four handheld microphones make this system useful when several people need to speak or sing without passing one mic around. The SG-400 pairs them with a receiver that has separate channel controls and LCD displays, so each mic has its own place in the setup. Auto-Scan is designed to select a frequency for each microphone, while Unique ID Pilot technology is intended to help prevent the four mics from interfering with one another. That combination suits group vocals, church services, presentations, and home events, though the listed range alone does not tell you how it will perform in every room.

Technical details

The system includes four metal handheld microphones and a metal receiver. Each mic has 65 UHF channels listed, and the product description also refers to 260 frequencies overall. Auto-Scan selects a frequency for each wireless mic, the receiver provides a separate control knob and LCD section for each channel. The microphones and receiver have LCD screens, with functions that include volume control, mute, Auto-Lock, and a battery indicator. The product name lists a range of 262 ft, but the supplied details do not explain the conditions for that figure.

Each microphone takes two 1.5V AA batteries, which are not included. The stated battery life is up to 6 hours, and rechargeable AA batteries are supported. Dynamic cartridges are described for both singing and speech, making the system more adaptable than a setup intended only for announcements. A practical limitation is that there is no information here about receiver connections, so make sure its available outputs fit the rest of your audio setup before choosing it.

Getting the most from it

This is a multi-mic system, not a single wireless mic with spare channels: it is designed for four people to use their own handheld microphone. For a church service, for example, one person can speak at the lectern while others keep their mics ready for readings or group singing. Separate channel controls can make it easier to adjust each mic without changing the others. By contrast, a simpler one-mic setup may be easier to manage if only one person ever needs to speak at a time.

Usage tips

Have four compatible pairs of AA batteries ready before an event, batteries are not included, and each mic requires two. Check the battery indicators during setup, and use the individual volume controls to set the microphones for their speakers rather than assuming one setting will suit everyone. Auto-Scan is intended to find frequencies automatically, but the product details do not explain how it behaves in a crowded wireless environment. Keep that in mind if you plan to use it alongside other wireless equipment.

Practical doubts

Are batteries included? No. Each microphone requires two 1.5V AA batteries, rechargeable AA batteries can also be used.

Can the microphones be muted? Yes. The listed functions include a mute feature, along with Auto-Lock and volume control.

Is it intended for both speech and singing? The description says the dynamic cartridges are intended for both. That makes it relevant for mixed events, though no further sound measurements are provided.

When it makes sense

A solid pick if you need four handheld mics for a shared event and want individual channel controls, LCD information, and automatic frequency selection in one system. Not the best choice if you need a clearly documented receiver connection, a stated battery supply, or more detail about performance in your specific venue, those points are not covered in the provided specifications. Choose it for the convenience of having several people mic'd at once, rather than for a setup where one microphone and a simpler receiver would do the job.
