SPL - Series One - Phonitor One D
Description
SPL’s Phonitor technology has raised the bar for professional headphone amplifiers. If lofty prices and exhaustive feature sets have kept you from experiencing this world-class level of headphone monitoring accuracy, this is a product you should know about. Spec’d with a streamlined feature set and the uncompromising design integrity of its big siblings, the SPL Phonitor One D provides easy entrée into SPL’s Phonitor universe. The goal is unerring headphone monitoring accuracy, and SPL equipped Phonitor One D with a stylish, uncluttered interface that gets the job done. Precision crafted in Germany, the Phonitor One D provides audiophile-grade componentry, impeccable build quality, solid operational feel, and elegant visuals that will look amazing in your studio or home entertainment system. Equipped with a premium AK4490 converter chip, the Phonitor One D provides two analog inputs and a USB digital input, along with Mac, PC, and iOS connectivity.
Phonitor One D gives you three front-panel-selectable stereo input sources. For analog, you have balanced 1/4-inch TRS and RCA connections; for digital, USB. The USB port also connects with your computer and iOS devices. Under the hood, the groundbreaking headphone playback technology you’re about to experience is the Phonitor Matrix, which makes monitoring on headphones sound like you’re monitoring on speakers. This is important because most music is mixed for playback on speakers, not headphones. SPL’s proprietary Phonitor Matrix makes their headphone amps unlike any other, sidestepping the tiresome “super stereo” effect and the hyped reproduction of reverberation and effects to deliver music exactly as it should be heard.
Speakers and headphones present music very differently. That’s why music mixed on headphones doesn’t “sound right” on speakers (and vice versa). The Phonitor Matrix evens the playing field with three parameters: Crossfeed, Speaker Angle, and Center Level. In Phonitor One D, the Center Level is preset to -1dB and the Speaker Angle to 30 degrees — values that SPL has determined to reflect the most common real-world conditions. The Crossfeed setting determines the crosstalk between left and right channels, the so-called inter-aural level difference. You can dial in the intensity of the Crossfeed via a front-panel potentiometer.
