120V Rail Headphone Monitoring Amplifier

The outstanding technical and sonic characteristics of the Phonitor 2 were translated into a more compact format to create the Phonitor mini.

Its ease-of-use, small and sturdy housing and affordable price, make the SPL Phonitor Mini the perfect headphone amp for home studios, hi-fi enthusiasts and mobile recording and mixing. It features the Phonitor Matrix to recreate speaker-like listening environment conditions.


Studio engineers will find in the Phonitor mini a high-quality headphones amplifier. On the one side, there is the traditional, analytical work with headphones as with a magnifying glass, which can be done always bearing 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 information 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.


Audiophile listeners get 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 reproduced correctly in their position when the loudspeakers form a stereo 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 stereo image is pushed further apart. All in all, the sound is not authentic anymore. With our Phonitor Matrix, music playback with headphones 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.


  • Headphone amplification for two sources
  • Headphone amplifier for all headphone systems and impedances
  • Loudspeaker-like reproduction with headphones
  • Monitoring alternative in studios and mobile units
  • Mobile reproduction of usual monitoring conditions
  • Headphone monitoring live or during recording


  • XLR connectors, electronically balanced
  • Impedance: balanced ca. 20kOhm, unbal. ca. 10kOhm
  • Max. Input Level: +32,5dBu
  • RCA connectors, unbalanced
  • Impedance: ca. 10kOhm
  • Max. Input Level: +20dBu
  • Considering that the RCA input is raised from -10dBV to +4dBu (approx. 12.7dB), the input level is comparable to that of the XLR inputs: +20dB + 12.7dB = 32.7dB
