Frequently Asked Questions

Which international standards does the receiver follow?

The system is designed in full accordance with IEC 61603-7 and IEC 60914 standards, ensuring international compatibility and reliability.

How many audio channels can the receiver support?

The CR-IR3002A supports button-type channel selection and can receive up to 8 or 16 independent audio channels.

Will the signal be interrupted by room lighting?

No. By using high-frequency transmission (2-6MHz, IEC61603 BAND IV), the system remains unaffected by high-frequency driving light interference.

What kind of battery power does it use?

It is powered by a built-in rechargeable lithium battery (3.7V/750mA), designed for long-term use and easy maintenance.

Does the device have an automatic power-saving mode?

Yes. If the receiver does not receive a signal for 5 minutes after the earphones are plugged in, it will shut off automatically to conserve battery.

How is the audio quality managed during signal drops?

The system features DQPSK digital demodulation and an auto-mute function. If the signal becomes too low, the audio is muted to ensure users only hear high-quality sound without noise.
