This crossfeed function is effective when listening with headphones.

Headphone (Crossfeed OFF)	Speakers

Normally, When listening with headphones, only the left sound of the sound source is heard directly in the left ear, and only the right sound of the sound source is heard directly in the right ear.
On the other hand, when listening with speakers, the left ear hears the left sound of the sound source and the right sound of the sound source, which is slightly quieter and slightly delayed. Also, the right ear hears the right sound of the sound source and the left sound of the sound source, which is slightly quieter and slightly delayed.

This function allows you to enjoy the same sound quality when listening with headphones as when listening with speakers.

Crossfeed ON Left ear: sound source L + R' Right ear: sound source R + L'

■ Feature

1. LR:
   The volume ratio and delay time of the left and right sounds synthesized and output to each ear are calculated based on the selected left and right speaker placement (spacing, listening).
   * spacing(m): distance between the left and right speakers
   * listening(m): distance between the left and right speakers and the listener
2. Direct:
   You can directly set the volume ratio and delay time of the left and right sounds that are synthesized and output to each ear.
   * Volume (%): Volume ratio of the synthesized left and right sounds
   * Delay (ms): Delay time of the synthesized left and right sounds
3. List:
   The system-defined crossfeed presets and user-defined presets are listed, allowing you to change the crossfeed value by selecting one of them.
