Our Phonitor headphone amplifiers found a huge fan base
among Hi-Fi enthusiasts. The Phonitor e comprises the most essential functions
and features in a slim and beautiful housing.

The Phonitor e is the ultimate headphone amplifier. It
offers connections for headphone operated both balanced and
unbalanced. With up to 3.7 W output power the Phonitor e delivers an impressive

The technical basis of all Professional Fidelity units is
our proprietory 120 V Rail Technology, which we also call VOLTAiR technology.
The name makes reference to the unequalled high voltage of 120 V (+/-60 V DC)
and the huge dynamic range of over 140 dB that goes with it.

The Phonitor e was designed for those who are looking for a
straightforward, powerful and excellent sounding amplifier for their
headphones. The feature set is – compared to its bigger brother, the Phonitor x
– reduced to the essentials.

What is the essence
of the Phonitor e?

Dual power amp for
balanced headphones

Phonitor e drives headphones operated both
balanced and unbalanced. For the balanced operation Phonitor e has an advanced
dual power amp built-in which delivers twice the power of the standard
1/4″ jack output. This tightens the bass response and makes the overall
playback even more relaxed and transparent. The front houses a 4-pol XLR
connector to connect the balanced headphone. Both the standard and the 4-pol
headphone outputs can be used simultaneously.

Optional DA converter

Phonitor e can be equipped with a DA converter. With that
installed the available inputs are expanded by USB, coaxial and optical digital
stereo inputs. The DA converter supports sample rates up to 192 kHz with 24
bit. It syncs automatically to the sample rate of the selected digital input.

Phonitor-Matrix with
two presets

The Phonitor-Matrix offers two presets. The Speaker Angle is
fixed to the most common setting of 30° representing the ideal angle for a
stereo speaker placement. For the Crossfeed adjustment there are two settings.
Crossfeed adjust the so-called interaural level difference. The setting C1 has
less crossfeed than C2.

Remote Control

To control the Volume you can use any IR remote control. The
cool part is that the Phonitor e learns your remote! Take the remote control of
your CD player for instance. There are many buttons and there are at least two
you don’t really use. Assign Volume Up and Volume Down to those buttons and let
the Phonitor e learn them. Please check the manual for more.

Professional Fidelity
• Pro-Fi-Serie

Phonitor e is part of our Pro-Fi series of products. Pro-Fi
stands for Professional Fidelity and it expresses that these products have
their roots in professional studio technology being optimized for high-fidelity
music playback.

We love simple elegance and a certain level of
understatement. Therefore we renounce over-dimensioned housing milled out
of a solid block and other mostly price-driving attributes of many high-end
products. Our background is come from professional studio technology, where
inner values and audio performance count the most.

Mastering studios give your records and CDs the final
tough – with SPL 120V technology. And because the Phonitor e is built with the
same technology it belongs to best headphone amplifiers on the planet. With its
extraordinary specifications and enormous headroom Phonitor e plays back audio
in the most relaxed and uncompromised fashion. Ear fatigue is reduced by far
and hearing session stay delightful for a long.

Preamplifier with VOLTAiR technology

VOLTAiR is the synonym for our 120V Rail Technology within
the Professional Fidelity series.

The audio signals are processing with an unequalled +/-60V

The Sound

120V Rail Technology is our reference
technology developed and manufactured to run on an operating voltage of
120 volts, which corresponds to twice that of discrete operational amplifiers
and four-times that of semiconductor operational amplifiers.

120V Rail Technology reaches outstanding technical and
sonic performances. Technically especially in terms of dynamic range and
headroom and sonically especially in reproducing the finest details and
delivering a totally relaxed sounding audio experience. Music sounds absolutely
natural and hearing fatigue is drastically reduced.

Even the best audio measuring equipment arrives at the
boundaries. In same situations we ended up just measuring the Audio Precision
Cascade 2 measuring device and we cannot say how good the 120V Rail Technology
actually performs.


The direct relation between operating level and maximum
level is fundamental for the classification: the higher the operating level,
the higher the maximum level a circuit can handle. And since virtually all
essential acoustic and musical parameters depend on this relation, a higher
operating voltage also has a positive impact on the dynamic range, distortion
limit and signal-to-noise ratio.

Do bear in mind that dB scales do not represent linear but
rather exponential increases. A 3dB increase corresponds to doubling the
acoustic power, +6dB correspond to twice the sound pressure level, and +10dB
correspond to twice the perceived loudness.

When it comes to volume, the 120V Rail Technology exhibits a
performance, in regard to maximum level and dynamic range, that is twice that
of common components and circuits given that its values are approximately 10dB

THD measurements of the 120V op-amp show a difference of
more than 3dB compared to the OPA134 at 36V — in terms of sound pressure level,
that corresponds to an improvement of more than 50%.

The operating level most commonly used for audio
equipment is 30 volts.
