Introduction
Phonitor
When we brought out the first Phonitor — the first ever headphone
amp with 120 Volt technology — back in 2008, the professional
audio world seemed to have been eagerly awaiting it. The success
of this unique headphone preamp was overwhelming. In hindsight,
we also had to wonder how none of us had come to the idea of com-
bining basic monitoring options, speaker simulation capabilities
and a headphone preamp. Ever since we call this new species a
„Headphone Monitoring Amp,“ which inspired the product name its-
elf: Phonitor.
Interestingly enough, the Phonitor not only became best friends with
thousand of professional users, it also won a lot of fans in the Hi-Fi
market segment. But that was by no means a coincidence — ulti-
mately, the Phonitor can be counted among the best headphone pre-
amps in the world thanks to our unique 120-Volt technology.

Many Phonitor users told us they wished they could also use the
unmatched signal quality that the Phonitor provides to feed their
speakers.
And so began to take form the idea of making its successor a full-
fledged stereo preamp that could become the heart of modern pro-
fessional and home systems alike where headphones have a pree-
minent importance.
We have further achieved new progress regarding the 120-Volt circuit
technology, so the technical specifications of the Phonitor 2 have
been improved in almost all areas, setting new standards.
Other improvements concern, particularly, the use of virtually any
type of headphone with any impedance. The Phonitor 2 is comple-
tely indiscriminating with low-impedance headphones starting at 10
Ohm and balanced headphones with load impedances starting at 40
Ohms.

The outstanding technical and sonic characteristics of the Phonitor
2 were translated into a more compact and less-expensive format to
create the Phonitor mini.
Its ease-of-use, small and sturdy housing and affordable price, make
the Phonitor mini the perfect headphone amp for home studios, hi-fi
enthusiasts and mobile recording and mixing.
The Phonitor mini is our high-end/low-size version of a premium
headphone amplifier. And it obviously features the Phonitor Matrix
too, to recreate speaker-like working conditions, plus the develop-
ments of the second generation of our 120-Volt amplifier technology.

Home Listening
Home users can now get — for an unheard-of value for money — a
headphone amplifier to enjoy an authentic sound reproduction with
headphones.
Headphones usually provide a 180-degree stereo image (the Super
Stereo effect), and that‘s exactly where the problem is rooted.
Generally speaking, music is mixed so that all instruments are repro-
duced correctly in their position when the loudspeakers form a ste-
reo triangle.
Thus, headphone reproduction is not the same as it was intended
during recording. The side component becomes too important during
playback, and effects like delay and reverb are reproduced in an
exaggerated way. The position of instruments and vocals in the ste-
reo image is pushed further apart. All in all, the sound is not authen-
tic anymore. With our Phonitor Matrix, music playback with headpho-
nes becomes a real delight thanks to an authentic perception of the
stereo width, a more precise localization of the sound sources and a
correct balance between effects and other elements.

Sound Engineers
Studio engineers will find in the Phonitor mini a high-quality head-
phones amplifier.
On the one side, there is the traditional, analytical work with head-
phones as with a magnifying glass, which can be done always bea-
ring in mind the lack of room influence. Working with a magnifying
glass has its advantages when it comes to discovering noises, clicks
and crackles, assessing edits, or spotting problems of single tracks.
On the other side, the Phonitor Matrix makes it possible to correctly
determine the position of sound sources in the mix. Spatial informa-
tion and effects are also more easily appraised, since the impression
of the stereo width created is not the 180-degree one usually heard
with headphones, but rather that of music being played back through
monitoring speakers in the control room.
