Phonitor 2

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 combining 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 itself: 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 — ultimate-

ly, the Phonitor can be counted among the best headphone preamps

in the world thanks to our unique 120-volt technology. With its excep-

tional technical specifications and a huge power margin, it can repro-

duce any musical material without the slightest modification, since

signal processing is not limited and, thus, signals are not altered at all.

Music sounds more natural and hearing fatigue is drastically reduced.

Given all that, it was easy to understand the enthusiasm with which

musicians, sound engineers and music lovers received the Phonitor

worldwide.

The New Heart Of Music Playback: Phonitor 2

Many Phonitor users told us they wished they could also use the un-

matched signal quality that the Phonitor provides to feed their speak-

ers. And so began to take form the idea of making its successor a full-

fledged stereo preamp that could become the heart of modern profes-

sional and home systems alike where headphones have a preeminent

importance. Moreover, we have achieved enormous advances with our

120-volt circuits, making the technical specifications of the Phonitor 2

a new standard in all respects: 141dB dynamic range, 107dB signal-to-

noise ratio (A-weighted in both cases), -112/-114 dB THD (headphone/

speaker output with +30dBu output level). Mind you, the THD mea-

surements define the limits of the measuring equipment but not those

of the Phonitor 2.

Other improvements concern specially the operation of virtually all

headphone types and impedances: the Phonitor 2 works seamlessly

with low-impedance headphones with load impedances as low as 10

Ohm (40 Ohm with balanced headphones).
