What is EN 55103?
EN 55103 is a two-part European product family standard for professional audio, video, audio-visual, and entertainment lighting control equipment. Part 1 (EN 55103-1) covers emissions; Part 2 (EN 55103-2) covers immunity. Unlike consumer multimedia standards (EN 55032 / EN 55035), EN 55103 addresses the unique electromagnetic environments of professional installations — broadcast studios, live event venues, post-production facilities, and entertainment lighting systems.
EN 55103 is harmonized under the EMC Directive 2014/30/EU for professional AV equipment. Both parts are required for a complete CE marking Declaration of Conformity.

Real-World Testing Examples
Digital Audio Mixing Console — EN 55103-1 + EN 55103-2 CE Marking
A professional audio manufacturer needed CE marking for a 32-channel digital mixing console for live events and installed sound (E2 and E3 environments). Compatible Electronics performed EN 55103-1 (2009) emissions at Newbury Park — conducted emissions on the AC mains and radiated emissions with all channels active passing representative audio. EN 55103-2 (2009) immunity testing measured audio output level deviation during each test as the Criterion A performance metric. EFT/Burst and conducted RF immunity on balanced XLR ports were the most demanding tests due to long cable runs typical of live event installations. The complete EN 55103-1 + EN 55103-2 CE marking package was delivered from Newbury Park.
Entertainment Lighting Controller — EN 55103-1 + EN 55103-2 + FCC Part 15
A stage lighting equipment manufacturer needed CE marking and FCC compliance for a DMX/RDM lighting controller for entertainment venues (E2 environment). Compatible Electronics performed EN 55103-1 (2009) conducted and radiated emissions and EN 55103-2 (2009) immunity — verifying DMX output signals remained stable during EFT/Burst injection on both AC mains and DMX output ports. FCC Part 15 Subpart B emissions were measured simultaneously via ANSI C63.4. CE marking and FCC compliance were delivered from one session at Newbury Park.
Broadcast Studio Camera — EN 55103-1 Emissions for E4 Broadcast Environment
A broadcast equipment manufacturer needed CE marking for a 4K studio camera for E4 (controlled broadcast studio) deployment with fiber CCU and SDI output. Compatible Electronics performed EN 55103-1 (2009) at Newbury Park at E4 environment limits — with the camera outputting 4K/50p video. The E4 limits reflect the controlled nature of broadcast studios with dedicated power and shielding, providing appropriate limits for professional broadcast facility deployment. Conducted and radiated emissions confirmed compliance, supporting the CE marking Declaration of Conformity for EU broadcast market distribution.
