SPL Pre One
Best audio enhancement for serious music enthusiasts.
This professional two-channel microphone preamplifier utilizes discrete analog technology to deliver an exceptionally open and transparent sound. It offers a wide gain range from +8 to +62 dB, accommodating various microphones. Each channel features 48V phantom power for condenser mics and a switchable 80 Hz high-pass filter to reduce low-frequency noise. A dedicated Hi-Z instrument input provides ultra-low noise performance for guitars and basses. Transformer-balanced inputs and outputs ensure optimal signal integrity, while two EQ presets offer tonal shaping. Rear-panel PAD switches provide attenuation for high-level sources, and balanced line outputs allow direct connection to audio interfaces or mixers.

Know before you buy
Yes, it is well-suited for ribbon mics. With a maximum gain of 62 dB and a very low noise floor, it provides enough clean headroom to amplify quieter ribbon microphones without introducing unwanted hiss.
Absolutely. The dedicated Hi-Z instrument input is designed specifically for high-impedance sources like electric guitars and basses, ensuring they sound clear and punchy without loading down the pickups.
These are fixed, musical EQ curves designed to add character quickly. 'Flair' generally adds presence and air to the high frequencies, while 'Contour' typically focuses on tightening the low-end and smoothing out the midrange, making them useful for quick tone shaping during tracking.
Yes, it is built for professional use. With transformer-balanced inputs and outputs, discrete analog circuitry, and a frequency response extending up to 200 kHz, it offers the signal integrity and transparency required for high-end recording chains.
Yes, the SPL Pre One comes with an external 12V power adapter. This design choice helps keep the power supply noise away from the sensitive analog audio circuitry inside the main chassis.
The switchable 80 Hz high-pass filter is a standard tool for cleaning up your signal. It cuts out low-frequency rumble, handling noise, or proximity effect buildup at the source, which saves you from having to fix these issues during the mixing stage.
