SPL Track One MK3

A modern mono channel strip designed for "studio-ready" recording

In a home studio setup or fast production environment, the goal is often the same: to obtain a clean, stable, and already shaped signal at the recording stage. This 1-channel console strip follows this logic by combining the essential processing of a console channel (preamplification, sibilance control, compression, limiting, and equalization) into a 1U rack format. The result: less external chaining, a more direct workflow, and more consistent takes right from capture.

Who is it for and what are its uses?

This channel strip is aimed at creators who want to save time and secure their recordings: singers and sound engineers in home studios, podcasters, streamers, rehearsal studios, or control rooms needing a reliable mono channel for lead vocals, voice-over, live bass, or acoustic instruments miked. Thanks to the 6.3 mm jack instrument input and the line input with adjustable gain, it can also serve as a versatile "front-end" before an audio interface, console, or recorder.

Integrated processing: control, musicality, and security on a single channel

Mic, line, and instrument preamp: an input adapted to each source

The mic preamp offers up to 68 dB of gain, a benefit for microphones requiring significant amplification. The 48 V phantom power activates as needed for condenser mics, while the 80 Hz high-pass filter helps clean vibrations, plosives, and rumbles even before dynamic processing. For line-level sources, the adjustable gain (from -12 dB to +22 dB) facilitates adaptation to your chain, and the front-panel instrument input allows direct connection of a guitar or bass with a gain range designed for playing dynamics and attack.

De-esser: cleaner vocals without smoothing character

The de-esser with adjustable "S" reduction targets sibilance (s, ch, t) that tires the ear and complicates mixing. Positioned correctly in the chain, it keeps vocals present and detailed while limiting excessive sibilance at the source, which is especially useful for narration, pop singing, and close-miking.

Compressor and soft limiter: controlled dynamics, peaks under control

The compressor features a threshold adjustment via compression control, make-up gain to restore level after reduction, and a gain reduction display to adjust by ear while keeping a visual reference. Additionally, the soft limiter acts as protection against overly strong transients: practical to avoid clipping during conversion, stabilize energetic vocals, or handle dynamic bass without losing musicality.

Semi-parametric equalizer and "air" band: sculpt without overprocessing

The equalizer offers semi-parametric low/mid and mid/high bands to precisely address problem areas (muddy, nasal, harsh), and an "air" band at 19 kHz to add a sense of openness and definition. This approach effectively brings vocals forward in the mix, restores clarity to an acoustic guitar, or adds brightness to a DI while maintaining a natural imprint.

Compressor-Link: stereo coherence when you need it

The Compressor-Link function facilitates paired use (for example with a second unit) to achieve consistent compression behavior on a stereo bus or source pair, useful for stereo recordings requiring a stable image.
