Stereo Listening With An "Traditional" Headphone Preamplifier - SPL HPM Manual

Phonitor Matrix
Our brain determines the direction of the sound by perceiving the time delay (interaural
time difference) and the level difference (interaural level difference).
Stereo listening with a "traditional" headphone pre-
amplifier
When listening to music with a "traditional" headphone amplifier, the right ear only
perceives the right signal (red line) and the left ear only perceives the left signal (green
line).
In contrast to listening to speakers the delayed and quieter signal of the respective
opposite side is missing.
As a result to this super-stereo-effect reverb and delay effects as well as EQ and pan-
orama adjustments are perceived more intense resulting in an exaggerated playback
on headphones which does not represent the music as approoved by the artist and
producer.
