Elevate your audio recordings and instrument performances with the SPL Pre One Preamplifier. Built on the legacy of SPL's renowned Channel One Mk3, this versatile 2-channel preamp offers exceptional transparency, detailed sound, and a professional-grade feature set. Designed and handcrafted in Germany, the Pre One combines precision engineering with a musical soul, ensuring your audio signals are captured and enhanced with unmatched clarity.
SPL Pre One: Unleash Crystal-Clear Sound, from Mic to Guitar
The SPL Pre One is equipped with dual preamplifiers featuring discrete transistor circuit designs. These circuits are meticulously tuned to deliver an open and transparent sound that captures every nuance of your input source. Whether you're working with demanding microphones or electric guitars, the Pre One ensures exceptional audio quality.
The second preamp includes a Hi-Z instrument input, making it perfect for direct connection of electric guitars and other instruments. With a wide gain control range of +8 dB to +62 dB, even the most challenging microphones can achieve their full potential. The onboard high-pass filter effectively reduces subsonic noise, keeping your recordings clean and precise.
SPL’s proprietary Flair and Contour circuits add creative sound-shaping options to each channel, while per-channel controls like polarity reverse, 48V phantom power, and 20dB pad offer unrivaled flexibility for professional audio workflows.
