About SPL Phonitor One

Become immersed in the world of superior sound with the Phonitor One Headphone Amplifier, a high-quality product from the reputable brand SPL. This advanced audio device is designed with a stylish, modern aesthetic that complements any home audio setup.

The Phonitor One Headphone Amplifier is engineered with an innovative Phonitor Matrix, ensuring outstanding sound quality that places it at the forefront of audio technology. The sound quality is paramount to us, and this amplifier is designed to deliver an audio experience that is both lively and precise.

The preamplifier stage of this reliable headphone amplifier features two Burr-Brown OPA 2134 SoundPlus operational amplifiers, specifically designed for audiophile circuits. These amplifiers are characterized by extremely low noise and minimal distortion of only 0.00008%, ensuring a clean and clear sound.

The power amplifier stage is designed as a push-pull amplifier in class AB mode, providing a higher gain and output voltage for a more robust sound. The output stage transistors are thermally coupled for consistent and stable sound production, even when operating low-impedance headphones.

The Phonitor One Headphone Amplifier also features the revolutionary Phonitor Matrix with adjustable crossfeed, allowing you to create mixes with headphones that sound identical to speaker output. The crossfeed function determines the crosstalk of the channels, and its intensity is fully variable, providing you with complete control over your audio experience.

This durable headphone amplifier is equipped with two line inputs, allowing you to connect a variety of sources such as a DA-converter, CD-player, mixer, synthesizer, or an analog tape machine/tape deck. The power supply ensures generous current reserves, laying the foundation for the performance of the entire device.
