The Hlabs EQ169+ is a high-end, single-channel analogue mastering equalizer inspired by the iconic Studer 169 design. It features fully stepped controls, three selectable EQ gain ranges, a 10-position high-pass filter, switchable low and high shelving filters, dual presence bands, and a transformerless signal path. Built with precision-matched components for ultra-low distortion, the EQ169+ delivers transparent, high-resolution tone shaping—ideal for modern mastering and mix engineers.
AT A GLANCE
• Fully stepped 11-position rotary switches for all parameters
• Three switchable EQ gain modes: Standard, Hybrid, and Mastering
• 10-step high-pass filter (12Hz to 160Hz), low shelf at 20Hz or 60Hz
• Two midrange presence bands with 22 selectable frequencies (150Hz–7kHz)
• High shelf options at 20kHz or 35kHz for added clarity and air
• Transformerless input/output and ±3dB output gain trim in 0.5dB steps
• Ultra-flat frequency response ±0.1dB (5.4Hz–35kHz+), SNR >108dB
MODERN MASTERING-GRADE PRECISION
The Hlabs EQ169+ expands on the legendary Studer 169 EQ topology with mastering-grade upgrades and fully stepped 11-position controls—ensuring exact recall and precision stereo matching. Built entirely with discrete through-hole components and ±0.1dB matched capacitors/resistors, it's handcrafted in France for ultimate sonic reliability and high-end build quality.
FLEXIBLE EQ CURVES FOR MIXING AND MASTERING
Three EQ gain settings offer tailored control:
• Standard Mode: ±12dB mids / ±15dB shelves
• Hybrid Mode: ±12dB mids / ±5dB shelves
• Mastering Mode: ±4dB mids / ±5dB shelves
A 10-position high-pass filter helps clean up low-end rumble, while the selectable low shelf (20Hz or 60Hz) adds weight or warmth as needed. The two mid presence bands span from 150Hz to 7kHz with 22 frequency points for detailed midrange sculpting. A smooth, musical high shelf at either 20kHz or 35kHz provides added brightness or "air."
TRANSPARENT SIGNAL PATH WITH HEADROOM TO MATCH
With transformerless input and output stages, the EQ169+ delivers exceptional clarity, while maintaining headroom up to +22dBU. An optional transformer-balanced version with Carnhill output is in development for those who prefer added colouration. The frequency response is ruler-flat within ±0.1dB across 5.4Hz–35kHz, with THD as low as 0.005% and a signal-to-noise ratio over 108dB—making it an ideal mastering EQ for pristine signal integrity.
BUILT FOR PROFESSIONALS, ENGINEERED FOR PERFORMANCE
Designed for serious mix and mastering engineers, the EQ169+ combines vintage heritage with modern control. Whether used on a stereo bus, vocal chain, or mastering rig, it offers precise, repeatable tone shaping in a compact, hand-built 1U rack unit. With its fully stepped operation, flexible tone curves, and ultra-clean signal path, the Hlabs EQ169+ is a world-class equalizer ready for the most demanding studio workflows.
