Inherited from some of SPL’s most revered high-end headphone amplifiers, Phonitor Matrix technology is a powerful tool that emulates the experience of mixing on studio monitors, translated to headphones.
Phonitor One features a center level preset hardcoded to -1 dB as well as a default speaker angle of 30 degrees to assume the most popular mixing settings.
On the Phonitor One's front panel, the Crossfeed function can be used to determine the crosstalk between channels, a technical metric known as "interaural level difference.”
The Phonitor One’s power amp output stage transistors are each thermally coupled to run coherently and contribute to a reliably consistent stereo image during listening.
The Phonitor One’s preamp stage is powered by two Burr-Brown OPA 2134 SoundPlus op amps specially designed for audiophile circuits and emitting a low distortion value of just 0.00008%.
The preamp’s true FET stage allows for a slew rate of 20V/µs resulting in a high-speed op amp and a jump in playback liveliness.
The output stage of Phonitor One has been specifically designed as a push-pull configuration in class AB mode.
Bipolar transistors then share amplification of both positive and negative half waves to produce higher output voltage and gain, even when compared to Class A operation.
