Q

What are the core advantages of CR4?


A: CR4 is an innovative product of a one-to-four true diversity four-channel wireless microphone integrated host. It features an integrated design, combining the receiver with the blade antenna into one unit. It is convenient to store, easy to install, can be carried around with one hand, and has an extremely high cost-performance ratio.

Q

Which usage scenarios are suitable for this?


A: CR4 is suitable for small event companies that often hold events at the same venue with no more than eight microphones, such as wedding planning, foundation celebration companies, as well as those that frequently conduct activities over long distances, including temple fairs, dragon boat races, military drills, parades, military reviews, and sports events.

Q

How is the sound quality?


A: The CR4 is equipped with not only the blade antenna but also a dipole antenna, which can ensure a more stable transmission of wireless audio and provide users with a highly realistic audio experience.

Q

How is the signal's anti-interference capability?


A: The CR4 is equipped with a one-click sweep frequency function, which enables quick identification of relatively clean frequency bands. The effective range is 130 meters (under optimal conditions), while the actual working range depends on the absorption, reflection and interference of the radio frequency signal.

Q

Can it be used with headphones or a conference microphone?


A: The CR4 can be used in multiple ways and can be freely combined. It can be easily paired with microphones, waist pouches, conference units, or any other audio transmitters (transmitting and receiving kit, audio transmission up to 1 kilometer).

Q

Is the operation convenient? Can the novice user get it?


A: The CR4 features AMSaudio's 4-channel XLR/CA plug output. It is easy to install, can be set up quickly and taken away with one carry, is more convenient for storage, has a low operation threshold, and the placement and setup of the main unit can be completed in "10 seconds", allowing beginners to master it quickly.

Q

Is it suitable for large-scale performances?


A: The CR4 is more suitable for smaller-scale performances. The scenarios where it is not applicable are as follows: when used in activities or exhibitions involving more than 8 channels (with any brand and model of microphones), or in venues where the microphone usage is extremely dense. In these scenarios, it is recommended to use with caution.

Q
How is the quality of the equipment? Is there any guarantee for after-sales service?

A: AMSaudio products are renowned for their durability (using high-strength materials), and the brand offers a nationwide dealer network support, a comprehensive warranty policy, and prompt after-sales service.

Q

How are the actual user reviews?


A: Based on market feedback, CR4 has received high praise for its portability and quick installation. Wedding planning teams and event organizers particularly appreciate its "one-to-four" design, which not only reduces equipment costs but also enhances efficiency.

Q

Are there any better options at the same price?


A: If the budget is limited but the requirements are clear (multiple microphones, lightweight), the CR4 is the top choice in terms of cost-effectiveness. If you are seeking the ultimate sound quality or for large-scale performance scenarios, you can consider the more premium models from AMSaudio, such as the GT6000 or TC2200 receivers.


Summary: AMSaudio CR4 offers high value for money, flexible deployment, and stable performance, making it an ideal choice for small and medium-sized events. It is suitable for users with limited budgets but who seek professional sound quality. It is especially recommended for use in wedding ceremonies, conferences, and small performances!
