Know before you buy
The Phonitor Matrix simulates the spatial characteristics of listening to speakers, which helps reduce ear fatigue during long sessions. By adjusting the crossfeed, it creates a more natural soundstage that feels less 'inside your head' than traditional headphone listening.
Yes, the Phonitor se is designed to handle demanding headphones with ease. It supports impedances up to 600 ohms and provides significant power output to ensure your headphones perform at their full potential.
No, the base model of the Phonitor se does not include an integrated DAC. It is a dedicated analog headphone amplifier, though it does offer an optional digital input expansion if you need to connect digital sources.
VOLTAiR technology operates at a much higher internal voltage than standard audio components. This provides increased headroom, a wider dynamic range, and lower distortion, resulting in a cleaner and more transparent sound profile.
The Phonitor se is designed for unbalanced connections. It features a standard 6.35 mm (1/4″) TRS jack, so it will not support balanced headphone cables without an adapter, and it does not provide a balanced output signal.
Volume is controlled via a high-quality, milled aluminum Alps RK27 potentiometer. This component is known for its precision and smooth tactile feel, allowing for very fine adjustments to your listening level.
