Product Details
💡 Founder's Vision
In mixing and mastering, low-frequency management is crucial to avoid muddy bass, phase cancellation, and energy loss across club PA systems. Therefore, Signal Lab created Elliptra EQ1 Master/Live to seamlessly shape side-channel low frequencies into a mono elliptical contour, combined with real-time matrix monitoring and dual-band phase correlation. Available in 2 versions for live sound and studio applications, it offers tailored flexibility and empowers modern sound engineers—especially those preparing vinyl masters who need effortless and precise low-end control without risk of needle tracking distortion.
🚀 Key Highlights
Elliptical Contour Shaping
Shape side-channel low frequencies into a solid mono contour with 3 modes: British Oval (tight British-style punch), Smooth Oval (natural warmth), and Linear Side Cut (surgical side-channel low-cut).
31-Band 1/3 Octave RTA
Real-time 31-band spectrum analyzer (20Hz - 20kHz) with color-coded gradient bars for precise frequency inspection.
Dual-Band Phase Correlation
Dual independent phase meters: Low-Band Correlation (20Hz - 200Hz) and Full-Band Correlation (20Hz - 20kHz) to detect phase cancellation risks instantly.
Matrix Zone & Solo Control
Comprehensive monitoring center: Left, Mono, Stereo, Phase Reverse, Right with Solo Mid, Solo Side, Mute L/R, and DIM controls.
Analog Vibe Saturation
6 analog saturation characters: Solid, Tube, Iron, OpA, VCA, and OFF for professional harmonic warmth.
Zero-Latency C++ Engine
Native C++ architecture with zero processing latency and ultra-low CPU footprint for studio and live sound environments.
Per-Band Phase Status LED Dots
Small LED indicator dots above each RTA band monitor per-band phase correlation in real time with 3 status colors: Cyan for healthy in-phase signals, Amber Gold for Vinyl Stereo Warning (excessive low-end width), and Crimson Red Glow for severe phase cancellation alerts.
Special Monitor Audition Buttons
3 dedicated solo audition check buttons in the Matrix Zone: Cube Mode (emulates Cube midrange speaker response for smartphone speaker and radio translation checks), Harshness Solo (3.15kHz ISO bandpass to remove ear fatigue), and Sibilance Solo (7.5kHz bandpass for surgical 'S' sound & cymbal inspection).
💻 Underlying Technology Stack
- Core Audio DSP Engine (C++ & Audio Framework):64-bit Floating Point precision audio DSP engine for uncompromised fidelity and zero unwanted distortion.
- Elliptical Filtering Matrix:Specialized elliptical filter algorithm converting low-frequency side signals to mono according to Egg Contour and Cutoff Frequency without disturbing mid-channel phase response—faithfully reverse-engineered from analog schematics and encoded into a high-precision audio plugin.
- Native Cross-Platform Binary:macOS Universal Binary (Apple Silicon M1-M4 & Intel) and Windows 10/11 64-bit.
🎯 Who is it for?
- Mastering & Mixing Engineers: Clean up low-end, control stereo width, and prevent phase cancellation.
- Live Sound Engineers: Maintain tight subwoofer response without room bass buildup.
- Music Producers: Achieve commercial-grade punch and warmth effortlessly.
- Vinyl Mastering Specialists: Keep low-end in mono to prevent vinyl cutting distortion.
