Your Introduction to the World of Phonitor Headphone Monitoring SPL’s Phonitor technology has elevated the standard for professional headphone amplifiers. If high pricing and extensive feature sets have prevented you from enjoying this world-class level of headphone monitoring accuracy, has a product you should be aware of. The SPL Phonitor One, with its reduced feature set and the rigorous design integrity of its larger brothers, is an accessible entry point into SPL’s Phonitor universe. The aim is precise headphone monitoring accuracy, therefore SPL designed Phonitor One with a beautiful, uncomplicated interface that does the job. The Phonitor One, meticulously made in Germany, features audiophile-grade components, flawless build quality, a strong operating feel, and attractive graphics that will look fantastic in your studio or home entertainment system. A headphone amplifier like no other Phonitor One has two stereo analog input sources that may be selected on the front panel via balanced 1/4-inch TRS and RCA connectors. The Phonitor Matrix powers the innovative headphone playback technology you’re about to encounter, making monitoring on headphones sound like monitoring on speakers. This is significant since the majority of music is designed to be played via speakers rather than headphones. SPL’s unique Phonitor Matrix distinguishes its headphone amps from others, eliminating the irritating “super stereo” sound and the overblown reproduction of reverberation and effects to deliver music just as it should be heard Experience the Phonitor Matrix Speakers and headphones convey music in very different ways. That is why music mixed for headphones does not “sound right” on speakers (or vice versa). The Phonitor Matrix levels the playing field by adjusting three parameters: crossfeed, speaker angle, and center level. In Phonitor One, the Centre Level is set to -1dB and the Speaker Angle to 30 degrees, which SPL has established to be the most typical real-world setting. The Crossfeed option controls the crosstalk between the left and right channels, known as the inter-aural level difference. The CrossFeed’s intensity may be adjusted using a front-panel potentiometer. Top-quality components The SPL Phonitor One, like other SPL products, exclusively employs high-quality components. The preamplification is handled by two Burr-Brown OPA 2134 SoundPlus operational amplifiers. This low-noise, low-distortion, high-speed FET stage is ideal for audiophile-grade circuits, with a slew rate of 20V/µs. Low-capacitance film capacitors are used in the signal route to ensure precise transmission of high-frequency signal components. The output stage is a push-pull Class AB amplifier with enough power to drive the majority of today’s popular headphone models.
