| SPL Phonitor Headphone Monitoring Amplifier Details
The Phonitor design is SPL's high-end interpretation for what a complete headphone amplifier should be. A well chosen system of Phonitor and headphones can by and large replace loudspeakers and offers all that is required for a successful session long listening periods without ear fatigue.
We therefore refer to the Phonitor as a headphone monitoring amplifier system.
The basis for this high-end development is our proven 120 volts reference technology based on handmade operation amplifiers. 120 volts corresponds to approximately four times the performance of standard analogue audio semiconductor technologies and twice that of the mot powerful designs. Through such 120 volts circuitry and processing, SPL reaches performance levels far beyond conventional designs in dynamic range and distortion levels, and the main technical specifications in music reproduction exceeds all known analogue or digital standards.
In addition to its standard monitoring functions the Phonitor offers new controls such as “Crossfeed“, “Speaker Angle“ and “Center Level“. These are the essential parameters that create the width, balance and overall space within a listening field and how we recognize them coming from the loudspeaker. Crossfeed simulates the frequency dependent interaural level differences from both channels. Speaker Angle determines the stereo width caused by frequency dependent interaural time differences. Center Level regulates the balance between phantom centre and L/R stereo signals.
Aside from its outstanding abilities as a loudspeaker substitute, the Phonitor offers well equipped studios a fully functional monitoring alternative. In addition one can take along the Phonitor into an unfamiliar studio or production environment that always provides the engineers or producers own monitor sound. Furthermore, with the Phonitor one can simply enjoy music as it was originally mixed, namely for playback over loudspeakers.
