Power amplifier

An amplifier is needed to supply enough power to the loudspeaker. The amplifier can either be an integrated part of the loudspeaker, or external. Special functions, such as stereo enhancement, loudness, or spatial sound must be switched off for measurement purposes. Filtering, such as bass, treble or equalization should be bypassed or set as neutral as possible.

 

The loudspeaker amplifier input is to be connected to the sound card output left channel.
