Description
Phonitor 2: The headphone amplifier and monitoring controller with 120V technology
Phonitor 3 is the ultimate headphone amplifier and monitoring controller with 120V technology. It offers the same monitoring quality as the big SPL mastering consoles – on loudspeakers and headphones. The analog Phonitor Matrix allows mixing and mastering on headphones in the highest quality – with the same spatial perception of the stereo stage as on loudspeakers.
Three analog XLR stereo inputs for various sources and a wide range of monitoring options make it the perfect monitor controller for demanding producers and mixing/mastering engineers.
Phonitor 3 can be equipped with the optional Expansion Rack, which is not only a 19″ rack housing, but it also expands the connection possibilities with three additional switchable stereo outputs for active loudspeakers or power amplifiers.
Great sound – for headphones
The Phonitor 3 offers connection for a standard headphone with a stereo jack plug on the front. Thanks to the enormous output power, all kind of headphones are driven effortlessly. Thus, it plays out the advantages of the SPL 120V technology and rewards the listener with an honest, detailed and at the same time vivid sound experience.
Great sound – also for loudspeakers
On the rear of the device, Phonitor 3 offers a stereo output which makes it a high-quality monitoring controller for any monitoring situation. Active speakers with an integrated power amplifier or passive speakers in combination with a power amplifier can be connected at this output.
Monitoring at the highest level
Phonitor 3 offers the same key technology – SPL 120V technology – and signal quality as the big SPL DMC and MMC mastering consoles.
Headphones or Speakers
The Output switch – simply switch from headphone to speaker playback. In the center position (Mute), no signal reaches the outputs. The VU meters light up red.
Free choice
Up to three stereo sources can be connected to the Phonitor 3. The source is selected via the Source switch.
Analog inputs
Three analog stereo inputs are offered, each with two XLR line inputs (left channel, right channel). Professional analog players with balanced outputs and line level can be connected here, for example high-quality DA converters or an audio interface.

Milled from solid
The massive 45mm volume control knob milled from aluminum is a haptic highlight. Its mass together with the Alps RK27 “Big Blue” potentiometer enhances the “spoon in the honey” feeling even further and provides perfect control of the monitoring level.
Monitoring without any compromises
The Phonitor 3 is a full-fledged monitor controller:
- Source selection
- Phonitor Matrix with Crossfeed, Speaker Angle and Center Level (the latter can be switched off)
- Mono/Stereo
- Laterality control
- Solo L/R
- Phase inversion for L and R
- L/R Swap
- Output switchable to headphones or speakers
- Mute
The Revolution: Phonitor Matrix
The Phonitor Matrix is the revolution in the headphone amplifier.
One of the unique features of SPL headphone amplifiers is the SPL Phonitor Matrix. It enables mixing and mastering engineers to create perfect mixes on headphones, which will translate perfectly to all types of stereo speaker systems.
But the Phonitor Matrix is not only designed for professional use in the studio. It also enables the hifi enthusiast to enjoy music on headphones, like if it was played back on speakers.
