IEC EN 61305-3 Home High Quality Audio Equipment and Systems - Methods for Measuring and Determining Performance - Part 3: Amplifiers

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 61305-3 testing. Applicable to all types of household high-end audio amplifiers. It also applies to equipment with multiple functions, including audio amplification functions, unless stated otherwise.

The electrical conditions shall be those specified in IEC EN 268-3, clauses 3, 5 and 8 to 12. The source emf values ​​and impedances are to be taken from IEC 268-15 for analog inputs and from IEC EN 958 for digital inputs, unless otherwise specified by the manufacturer.

The highest value should be specified for any position of the volume control from 250 Hz to 6,3 kHz, from the position of maximum gain to the position that provides 46 dB attenuation. Any trim control should be set to the mechanical center position.

For any frequency between 63 Hz and 12,5 kHz, from 1 dB below the power or distortion limited rated output voltage to the power level corresponding to 50 mW or -30 dB attenuation, whichever is the worst case value should be given. The smaller of the two values ​​should be selected.

Specify frequencies where the output power or voltage giving a given total harmonic distortion value is 3 dB below the rated output power or the distortion limited voltage.
