SPL are happy to introduce the successor of their legendary Phonitor 2 headphone preamp. They have kept all proven features while incorporating some major improvements - as such, the new Phonitor can be used as the ultimate monitor controller and preamp for three different sources. Likewise, SPL revised the 120V Rail Technology in order for it to perform better, which resulted in their measurement gear being outclassed. Even their creative team got even more creative and came up with a fascinating name: "Phonitor 2".


  • 120V Rail headphone amplifier, preamplifier and monitor controller
  • For all headphones with impedances >10Ohms (>40Ohms for balanced headphones)*
  • Innovative Phonitor Matrix: speaker-equivalent listening on headphones
  • Laterality control: super-fine balance control
  • Solo L/R, Polarity ø L/R, Mono/Stereo
  • Volume remotely adjustable (learns any IR remote control)
  • Maximum output power: 2 x 2W (1kHz/300Ohm)
  • Frequency response: 4Hz - 480kHz (-3dB)
  • THD+N: 0.00091% (HP), 0.00085% (Line)
  • Dynamic range: 133.62dB (HP), 134.37dB (Line)
  • Made in Germany

When SPL 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, they also had to wonder how no one had come to the idea of combining basic monitoring options, speaker simulation capabilities and a headphone preamp.

Ever since SPL 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.

120V Rail Technology

But that was by no means a coincidence - ultimately, the Phonitor can be counted among the best headphone preamps in the world thanks to SPL's unique 120V Rail technology. With its exceptional technical specifications and a huge power margin, it can reproduce 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.

Phonitor 2

Many Phonitor users told SPL that 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 professional and home systems alike where headphones have a preeminent importance. Moreover, SPL have achieved enormous advances with their 120V Rail Technolgy, making the technical specifications of the Phonitor 2 a new standard in all respects: 141dB dynamic range, 107dB signal-to-noise ratio, -112/-114 dB THD (headphone/speaker output with +30dBu output level). Mind you, the THD measurements 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).

As always, the Phonitor 2 remains first and foremost a headphone preamp, which is easy to identify given the elaborate loudspeaker simulation for headphones. Considering that the 120 volt amp provides everything needed to pre-amplify, manage and control the volume of line level signals, the latter are now also available at the output on the rear panel.

Besides headphones, it is now possible to connect active loudspeakers and power amps directly at the output. If there is the need for more than one stereo speaker set, it is recommended to use a passive distribution module. It is important to know that all controls can be used for both outputs with headphones and loudspeakers. Obviously, loudspeaker simulation makes no sense when using real loudspeakers. However, owners of electrostatic headphones could connect their headphones to the output and use the simulation feature as well. Likewise, all monitoring options (phase reverse, solo, mono, mute) can be selected for both outputs, so that the Phonitor 2 can be used as Monitor Controller for up to three different sources.
