Passive Tube EQ With Vintage Character

At the core of the Classic Equalizer is a passive boost-and-cut topology that shapes tone in a broad, natural way. Low-frequency shelving options allow you to add weight or tighten the bottom end, while high-frequency peak boosts—with adjustable bandwidth—let you enhance presence and air with precision. The tube and transformer stages introduce subtle harmonic richness, giving your audio a smooth, cohesive quality without overpowering the original signal. This combination makes it ideal for adding depth and musicality across a wide range of material.

Flexible Stereo Control for Professional Workflows

Built for modern hybrid studios, the EQP-1 features balanced inputs and outputs, a clean bypass switch and an internal power supply for reliable operation. Its stereo configuration makes it well suited for bus processing and mastering applications, where consistency and recall are essential. With carefully selected frequency points and intuitive controls, it integrates seamlessly into both analog and digital setups. The Tegeler Audio Classic Equalizer EQP-1 offers a refined, musical approach to EQ that enhances mixes with timeless analog tone.
