FCC Certification and Whole Home Audio System
Whole Home Audio System, especially its core component Multi-room Streaming Amplifier should pass FCC Certifidation. All multi-room streaming amplifier from OpenAudio pass FCC Certification. If some multi-room streaming amplifier doesn’t pass the FCC Certification, it is better not bought it.
What is FCC Certification
FCC certification, issued by the Federal Communications Commission, is a requirement for electronic devices entering the US market, ensuring they comply with regulations on electromagnetic interference and radio frequency emissions. This certification is crucial for products containing radio transmitters, including radio, marine, and satellite equipment.

The Federal Communications Commission (FCC) is an independent government agency, overseen by the U.S. Congress, responsible for implementing communication laws and regulations throughout America as well as enforcing them.
Manufacturers who wish to sell telecom, licensed RF, and low powered transmitters in the United States must have their products tested by FCC listed or accredited lab and certified by the FCC for EMC/Telecom compliance.
What is a Telecommunication Certification Body (TCB)?
A Telecommunication Certification Body (TCB) is a designated organization authorized by the Federal Communications Commission (FCC) in the United States to issue certifications for certain types of telecommunications equipment.
The FCC requires that certain types of telecommunications equipment, such as radio frequency devices, must be tested and certified before they can be marketed or sold in the United States. The purpose of this certification is to ensure that the equipment complies with FCC rules and regulations, including those related to safety, emissions, and interference with other devices.
A TCB is responsible for reviewing and testing the equipment to ensure compliance with FCC regulations, and issuing the necessary certification once compliance has been demonstrated. The TCB is also responsible for ongoing compliance monitoring of certified equipment.
The FCC has authorized several organizations to serve as TCBs, and these organizations must meet certain requirements and follow specific procedures in order to maintain their TCB status.
FCC ID vs. FCC SDOC

FCC SDOC (Supplier’s Declaration of Conformity) and FCC ID are both FCC authorizations for electronic devices, but they apply to different types of products. FCC SDOC is for most products without wireless functions, like household appliances and lighting fixtures, while FCC ID is for wireless communication devices like smartphones and Bluetooth devices.
And more importantly, if one products design with module which have pass FCC ID, it can only pass SDOC as a whole. In other words, “In cases where a device has both intentional and unintentional radiators, such as a Wi-Fi-enabled device, the unintentional radiator portion (e.g., the digital circuitry) can be authorized under SDoC, while the intentional radiator (e.g., Wi-Fi transmitter) requires FCC certification.”
