برای دوستان علاقه مند فقط همین مطلب رو بخونن تا یکی از بهترین قابلیت های آمبلی ها دستشون بیاد ( crossfeed )
این مسئله قابلیتی رو به هدفون ها میده که بدست آوردنش با اسبیکر فوق العاده سخته ( اگر بدست بیاد در لحظه فقط برای 1 شنونده بدست میاد)
Crossfeed and other audio processing
Crossfeeding blends the left and right stereo channels slightly, reducing the extreme channel separation which is characteristic of headphone listening and is known to cause headaches in a small fraction of listeners. Crossfeed is used to compensate for extreme separation of sound sources in older stereo recordings. Crossfeed also improves the soundstage characteristics and makes the music sound more natural, as if one was listening to a pair of speakers. While some swear by crossfeed, many prefer amplifiers without it. The introduction of DSP technology led a number of manufacturers to introduce amplifiers with 'headphone virtualization' features. In principle, the DSP chips allow the two-driver headphone to simulate a full Dolby 5.1 (or more) surround system. When the sounds from the two headphone drivers mix, they create the phase difference the brain uses to locate the source of a sound. Through most headphones, because the right and left channels do not combine as they do with crossfeed, the illusion of sound directionality is created
