SPL Phonitor One 1901 - Headphone Monitoring Amplifier

Phonitor One - The Audiophile Headphone Amplifier with Phonitor Matrix

Transform Your Listening Experience with Phonitor One Dive into the world of pristine audio with the SPL Phonitor One, a headphone amplifier that's a cut above the rest. Designed for audiophiles and professionals alike, it features the groundbreaking Phonitor Matrix and top-tier sound quality, ensuring an unparalleled auditory journey.

Unmatched Sound Purity and Power At the heart of Phonitor One's preamplification are two Burr-Brown OPA 2134 SoundPlus™ operational amplifiers, renowned for their ultra-low noise and minimal distortion. A true FET stage and low capacitance film capacitors in the signal path enhance the liveliness and precision of high-frequency sound components. Panasonic ‘Electric Double Layer’ gold electrolytic capacitors provide unmatched storage capacity, ensuring a rich and detailed sound experience.

Robust Output Stage for Headphones and Speakers The headphone amplifier's output stage operates in class AB mode, sharing the amplification of positive and negative half-waves for increased gain and output voltage. Thermally coupled bipolar transistors contribute to a stable and consistent sound image. The power supply's low source resistance ensures ample current reserves, even for low-impedance headphones.

Revolutionary Phonitor Matrix for Perfect Mixing The Phonitor Matrix is the heart of the Phonitor One, enabling mixing and mastering engineers to create perfect mixes on headphones. It corrects the unnatural stereo image of conventional headphone listening by replicating the natural crossfeed of stereo speakers, ensuring a more authentic and comfortable listening experience.

Versatile Connectivity Phonitor One offers two analog stereo inputs (TRS and RCA) for connecting a range of audio sources. Its design ensures compatibility with professional-level devices, providing an optimal control range for a variety of headphones.

Impeccable Design and Control Featuring a 45mm volume control knob milled from aluminum and paired with an Alps RK27 “Big Blue” potentiometer, Phonitor One delivers a tactile and precise volume adjustment experience. The device's thoughtful design elements ensure both visual appeal and functional superiority.

Experience the Sonic Excellence of SPL Drawing from SPL's extensive experience in audio engineering, Phonitor One is meticulously crafted using Through-hole technology on its circuit boards, ensuring the use of only the highest quality components.
