So the question is: how do you choose between the different AMSaudio series?
The answer is actually very simple. It mainly comes down to two things:
Where will it be used? And how many microphones will be used at the same time?
Best Choice for Small & Medium Events: CR4 — Grab the Case and Go
For small event companies, it’s common to use fewer than eight microphones in a single venue, such as weddings, groundbreaking ceremonies, corporate meetings, and similar events. In these situations, the CR4 is the perfect partner.
AMSaudio CR4
The CR4 is a true diversity four-channel wireless microphone system featuring an integrated antenna-and-receiver design. It combines the receiver and paddle antenna into one compact structure.
Its biggest advantage is portability. The main unit and antennas are fully integrated, so there is no need for additional antenna installation or separate directional antennas. The system itself uses a log-periodic antenna together with a dipole antenna — one handles wide coverage while the other helps reduce noise and maintain signal stability.
The entire setup fits neatly into a carrying case. Once on-site, simply open the stand and it’s ready to use within seconds. Easy to transport, quick to deploy.
In terms of sound quality, the CR4 delivers clean and clear audio with impressively low background noise, making it more than capable for small and medium-sized performances and events.
The Rackmount Favorite: E300 — Professional Wireless Performance at an Affordable Price
Some experienced event professionals still prefer the traditional rackmount style. They like equipment that feels solid, reliable, and easy to install into existing racks.
That’s exactly where the E300 and E400 series come in.
These two series are designed specifically for small and medium-sized events, comfortably supporting around 12 microphones within one venue. Among them, the E300 stands out for its exceptional value. At just over a thousand RMB, it offers professional live-performance wireless microphone capabilities at a highly competitive price point.
For weddings, small launch events, or gatherings with around one hundred attendees, the E300 is an excellent choice for users who want more channels without stretching the budget.
If you already own a CR4 and occasionally handle medium-sized events, the CR4 can still perform reliably. But if you want to expand your channel count without making a major investment, the E300 becomes the ideal upgrade.

The Multi-Channel Powerhouse: GT6000 — Built for Large-Scale Events
If your projects regularly involve large multi-channel events requiring dozens of microphones simultaneously — such as large conferences, music festivals, or corporate annual events with hundreds of attendees — then the CR4 and E300 are no longer the right tools for the job.
This is where the GT6000 series takes over.
AMSaudio GT6000
The GT6000 is capable of supporting 60 to 80 microphones within a single venue, delivering wide coverage and outstanding anti-interference performance. It offers a completely different level of operational confidence for large-scale productions.
Its advanced dual-antenna cascading design allows multiple receivers to connect and share a single antenna system, ensuring stable operation even during complex large events.
In addition, the built-in signal compensation function allows direct connection to paddle antennas without requiring external antenna splitters or amplifier modules. This keeps the overall system both simpler and more reliable.
If your events frequently involve crowds of 300 to 400 people or more, with microphone counts easily exceeding 20 or 30 channels, the GT6000 is the solution you should be looking at.
Final Thoughts
When choosing an AMSaudio wireless microphone system, ask yourself two simple questions:
Where will it be used?
How many microphones will be used at the same time?
Once those answers are clear, the right choice becomes obvious.
At the end of the day, there’s no need to overcomplicate things. Don’t use oversized equipment for small jobs, and don’t expect entry-level setups to handle large-scale productions. Choose the system that matches the scale of your events.
With more than ten years of experience in the professional audio industry, AMSaudio understands that users must balance performance, stability, and budget. Thanks to its strong cost-performance ratio and reliable quality, AMSaudio has become one of the preferred Chinese brands among event companies and performance teams.
This is also why AMSaudio’s live performance wireless microphone systems continue to rank among the top sellers nationwide, with a market presence that speaks for itself.
