Crossfeed

A new feature of the 

2

Control is the CROSSFEED control for both head-

phone  outputs,  which  was  derived  from  the  high-end  headphone 
amplifier 

Phonitor

. From their principle, headphones have the disad-

vantage of producing a 180 degree stereo panorama – the CROSSFEED 
control can be used to adjust a stereo panorama that corresponds to 
a stereo speaker image. Based upon the imaging of a speaker set po-
sitioned on angle of 30 degrees towards the listener, the crosstalk of 
both channels can be regulated to meet individual demands. Whenever 
speaker monitoring may not be possible or if an monitoring alternative 
to speakers is required, the 

2

Control allows for judging mixes also on 

headphones.

Source and speaker output switches as well as mono and dim switches 
provide the main monitoring functions for a complete controller – with-
out overloading user interface and electronics. 

Speakers or headphones?

The 

2

Control  encompasses  advantages  of  both  kinds  of  monitoring 

methods:  On  one  hand  the  analytical  headphone  monitoring  is  like 
working with an acoustic magnifier but without external room influenc-
es; on the other hand, loudspeaker monitoring forgoes the microscopic 
effect, but provides for room ambience.

Working with the magnifier effect of headphones has the advantage of 
safely hearing clicks or similar defects and helps in fine tuning cross-
fades or to judge tonal problems in individual tracks.  On loudspeakers 
such analyses are much more difficult, as such problems just are not as 
apparent when one is working without being able to “zoom in” aurally. 

Conversely,  loudspeakers  provide  monitoring  with  the  advantage  of 
spatial balance in a (definable through placement) stereo width, which 
in turn provides the illusion of an acoustic stage.

With the analog Crossfeed control you can match headphone listening 
to  speaker  listening.  The  range  of  headphone  applications  becomes 
much broader and you may find more or new scenarios in your working 
life.
