The Professional "Big-Iron" Front End for Instant Studio Polish
Now in its third generation, the SPL Track One Mk3 Premium has been thoroughly revised with enhanced technical specifications and a highly intuitive interface optimized for modern tracking workflows. Designed for musicians, voiceover artists, podcasters, and mixing engineers who require broadcast-ready audio quickly, this premium module eliminates the need for messy outboard routing. Outfitted with world-class Lundahl transformers at both the input and output stages, it adds weight, punch, and an expensive analog character directly to your recording chain. Beyond tracking, its flexible line-level handling allows it to operate as an "analog hardware plugin" patched directly into your DAW's inserts during mixdown.
Product Description
Premium Pre-Amplification with Lundahl Iron:
The Track One Mk3 Premium architecture features two independent, sound-neutral solid-state preamplifiers built for pristine clarity:
Microphone Preamp: Delivers up to +63 dB of low-noise gain. Backed by the passive level boost of the Lundahl input transformer, it provides headroom for delicate ribbon, dynamic, and condenser microphones. It features independent 48V phantom power and a 6 dB/octave high-pass filter to roll off structural rumble and low-end impact noise below 80 Hz.
Instrument & Line Preamp: Features a selectable, low-noise front-panel Hi-Z input ($1\text{ M}\Omega$) supplying up to +35 dB of gain, tailored for active basses and electric guitars. A balanced line input provides up to +22 dB of clean gain for processing pre-recorded DAW tracks.
The Renowned Auto-Dynamic De-Esser:
To eliminate harsh sibilance ($S, Z, T$ sounds) without altering the vocal character, the unit integrates SPL's iconic De-Esser technology. Traditional compressors crush the upper frequency band, leaving vocals sounding muffled. SPL’s circuit isolates the offending sibilant frequencies in a very narrow band and mixes them back into the main audio path phase-reversed, dynamically canceling out the harshness. Driven by an Auto-Threshold matrix, the processor automatically adjusts its threshold to compensate for the performer's changing distance from the microphone. This ensures consistent, transparent de-sing with just a single S-Reduction knob.
Adaptive Dynamics Control (Compressor/Limiter):
Dynamic leveling is governed by a highly musical, low-noise VCA Compressor/Limiter controlled via a single knob. The device utilizes automated, signal-dependent time constants (attack and release) that adapt dynamically to the incoming signal. Long, held notes receive a slower attack time automatically, while sudden transient peaks are caught instantly. Engaging the Limiter switch transforms the circuit into a soft limiter, with the threshold controlled by the main compression pot. A dedicated Make-Up Gain control provides up to +20 dB of clean level recovery to maintain ideal gain staging.
Surgical 3-Band EQ and the Legendary Air Band:
The EQ section is custom-tuned to enhance vocals, acoustic instruments, and line-level sources swiftly and effectively:
LMF Filter (Low-Mid Frequency): Covers 30 Hz to 700 Hz (spanning 4.5 octaves) with up to $\pm$12 dB of boost or cut to remove boxy room resonances or build low-end warmth.
MHF Filter (Mid-High Frequency): Ranges from 680 Hz to 15 kHz (spanning 4.5 octaves) with $\pm$12 dB of control to manage vocal presence and articulation.
Air Band Filter: Utilizing a premium coil-capacitor network with a bell characteristic centered at 19 kHz, it provides up to $\pm$10 dB of curve adjustment. This adds an expensive-sounding, silk-like top-end sheen and spacious breath to vocals without inducing harsh artifacts.
Key Features
PREMIUM LUNDAHL TRANSFORMERS: Outfitted with high-end Lundahl transformers at both input and output stages for a deep, authoritative "big-iron" analog character.
ULTRA-TRANSPARENT PREAMP STAGE: Solid-state architecture offering up to +63 dB of gain for microphones and up to +35 dB for instrument DI tracking.
PHASE-CANCELLING DE-ESSER: Auto-threshold tracking circuit isolates and phase-cancels sibilance invisibly, adapting instantly to changing microphone distances.
AUTOMATED VCA COMPRESSOR: Set-and-forget one-knob design automatically recalculates attack and release coefficients on the fly based on the input program.
SOFT LIMITER TOGGLE: Dedicated switch converts the VCA compressor into an unobtrusive soft limiter for managing high-transient overloads.
19 KHZ COIL-CAPACITOR AIR BAND: Custom bell-curve high-frequency filter delivers up to 10 dB of beautiful, expensive-sounding vocal sparkle.
ANALOG DAW PLUGIN ROUTING: Processes line-level signals effortlessly, allowing the hardware unit to operate as an external insert mix processor.
COMPRESSOR LINK FOR STEREO: Features rear-panel 1/4" link jacks to pair two Track One units together under a single master control for coherent stereo tracking.
BOUTIQUE CHASSIS BUILD: Constructed with a heavy-duty steel housing, a 4mm thick black-anodized aluminum faceplate, and solid-milled aluminum control knobs.
