2Control

Crossfeed

The CROSSFEED control interacts with a complex analog circuitry that

– simply put – serves to simulate the listening experience from loud-

speakers on headphones. The ON switch below the control activates

and deactivates the circuitry. CROSSFEED regulation is always applied

to both headphone outputs simultaneously and is present at the head-

phone outputs only (no effect on the speaker outputs).

Adjustments can be made between a minimum and maximum value.

The more you turn the control to the right, the more of the headphone’s

super stereo width is reduced – in a maximum setting almost up to a

mono signal impression.

Adjusting CROSSFEED is an individual process. Depending on head-

phones, music, individual preferences etc., your CROSSFEED adjust-

ment simply should achieve the most significant advantage in monitor-

ing your stereo mixes. We recommend comparing CROSSFEED settings

to your own speaker monitors in order to get a familiar imaging – this

ensures coherent conditions in speaker and headphone monitoring.

The circuitry for the CROSSFEED control is derived from the reference

headphone amplifier Phonitor. In the Phonitor, the loudspeaker imag-

ing simulation is realized with three controls: Crossfeed, Speaker Angle

and Center Level. The Phonitor Crossfeed control allows to adjust the

frequency-dependent crossfeed simulation of both channels by adjust-

ments of interaural level difference. The Speaker Angle switch provides

for frequency-dependent simulation of your stereo image width by ad-

justments of interaural time difference. Finally, with Center Level you

can adjust the intensity of center signals – the relation between center

and side signals changes when the super stereo width is transferred to

a stereo image that is equivalent to loudspeakers.

For the 2Control the parameters “Speaker Angle” and “Center Level”

are adjusted to a simulated speaker angle positioning of 30 degrees

(the standard speaker angle) at the respective CROSSFEED settings.*
