What is ETSI EN 301 357?

ETSI EN 301 357 covers cordless audio devices operating in the 25 MHz to 2 GHz frequency range. Part 1 specifies the technical characteristics and test methods; Part 2 provides the harmonised EN covering the essential requirements of Article 3.2 under the EU R&TTE Directive. The standard applies to analogue and digital wireless audio transmission devices used for music, voice, and audio monitoring applications — primarily in professional audio and entertainment lighting environments.

EN 301 357 is closely related to the Professional AV EN 55103 standard which covers the EMC requirements for professional audio, video, and entertainment lighting equipment. For the RE Directive EMC requirements (Article 3.1(b)) see our ETSI EN 301 489 page — specifically EN 301 489-9 which covers wireless microphones and cordless audio.

🔎 EN 301 357 and Professional Audio: EN 301 357 covers the radio performance (Article 3.2) of cordless audio equipment — transmit power, spurious emissions, frequency stability. The companion EMC standard is EN 301 489-9. For the broader professional AV product-family EMC standard covering both wired and wireless professional equipment, see EN 55103-1 (emissions) and EN 55103-2 (immunity) at our Newbury Park facility.
