CTA’s Audio and Video Systems Committee (R4) recently published CTA-2054 Specification for Selecting an Amplifier for use with a Loudspeaker System. This standard defines test conditions and measurement procedures for determining a maximum rated loudspeaker drive level of single-channel and multi-channel power amplifiers related to matching them with passive loudspeakers. It also describes a standardized format for reporting the measurement results, compatible with CTA-2034-B and CTA-2010-C reporting. Said amplifier(s) shall not be packaged with or specifically intended for use with dedicated loudspeakers. This standard applies to full-range amplifiers intended for home audio use and that use AC mains power.
