EQ169
Equalizer
EQ169 is a musical, no-nonsense 3-band tracking EQ inspired by the iconic Studer 169 console. Designed for tone shaping rather than clinical correction, it delivers fast, intuitive results that sound right immediately. The signature semi-parametric Presence band sweeps smoothly from 150 Hz to 7 kHz, while the fixed ±15 dB high and low shelves add weight, air, and clarity in seconds. A multicolour output level indicator lets you monitor post-EQ saturation with confidence. Built as a faithful circuit replica with high-grade op-amps and relay bypass, EQ169 is the perfect tracking companion to PRE169 in any 500-series setup.
Inspired by a studio classic, tuned for modern tracking
EQ169 is a faithful evolution of the legendary Studer 169 console EQ, designed for musical decision-making rather than forensic correction. It is the kind of equalizer you reach for when you want results that sound right immediately, especially during tracking. Every control invites confidence, speed, and intention.
Designed for tone, not surgery
With its simple 3-band layout, EQ169 encourages bold, musical moves. The fixed high and low shelves deliver instant weight and air, while the signature Presence band offers smooth, continuous control across the most expressive part of the spectrum. It is forgiving, flattering, and impossible to make harsh.
The signature Presence band
The semi-parametric Presence filter sweeps from 150 Hz to 7 kHz, making it ideal for vocals, guitars, drums, and bass. Whether you are adding forward energy or carving space, the response remains smooth and musical across the entire range.
Built like the original, refined for reliability
EQ169 is a precise replica of the original Studer circuit, using transformerless input and output stages with high-grade op-amps. A relay-based bypass ensures transparency, consistency, and signal safety even in power-loss scenarios.
Tracking confidence with visual feedback
The multicolour output level indicator lets you monitor post-EQ level and saturation at a glance, helping you push character intentionally without losing control.
Perfect companion to PRE169
Paired with the PRE169, EQ169 becomes a powerful front-end chain for tracking, offering classic tone, speed, and musicality in a compact 500-series format.
