SPL Phonitor x Headphone Amplifier

The Phonitor x is the ultimate headphone amplifier. Thanks to VOLTAiR technology it powers headphones operated both balanced and unbalanced up to 3.7 W. The Phonitor x is not just a headphone amplifier, but also an excellent preamplifier that can also drive power amplifiers or active monitors.

Now your headphones can be operated ‘balanced’. Phonitor x has an advanced dual power amp built-in that drives headphones balanced which twice the power of the standard 1/4" jack. This tightens the bass response and makes the overall playback even more relaxed and transparent. The front houses a 4-pin XLR connector to connect the balanced headphone. The standard and the 4-pin headphone outputs can be used simultaneously.

The Phonitor matrix has become simpler, because the Phonitor x is purely designed for audio playback. Features like Center Level adjustment, Solo and Polarity are of use in music production and have therefore been left off in the Phonitor x. We have also reduced the amount of selectable Speaker Angles from six to four leaving off the 15° and 75° angles.

Phonitor x is also a full-fledged stereo preamplifier, allowing up to five stereo sources – two in the analog domain offering XLR connectors for a balanced source and RCA connectors for an unbalanced source. With the optional DA converter installed three more digital stereo sources can be connected via USB, coaxial and optical connectors.

You can connect your active loudspeakers or power amplifier directly to the Phonitor x. The rear Speaker Outputs provide both balanced (XLR) and unbalanced (RCA) connections.
