The "CORDA ARIETTA" headphone amplifier of the MEIER-AUDIO is equipped with a low level crossfeed filter for relaxing listening by headphones. Below are some measurements of the Meier crossfeeder.
See also audio tests of the headamp here.
|Crossfeed filter frequency response.|
The frequency responses of the crossfeed filter are made by frequency analysis of white noise: one channel signal is for frequency responses of lowpass and highboost filters, mono two channels signal and independent two channels signal is for approximate stereo frequency response.
|Crossfeed filter time delay response.|
The time delay response of the crossfeed filter are made by analysis of one channel sinusoidal signal.
