Quagliardi 523 ParaShelving EQ: Precision Meets Musicality

The Quagliardi 523 ParaShelving EQ completes the Quagliardi channel strip with a dual-band equaliser that balances surgical control and broad tonal shaping. Each band offers full control over gain, frequency, and bandwidth, with instant switching between parametric and shelving modes – making the 523 equally effective for corrective work or musical enhancement.

True Bypass guarantees absolute signal integrity when disengaged, while the proprietary BLUE harmonic colouration circuit adds punch, weight, and character when needed. The result is an EQ that feels confident on tracking, mixing, and creative tone shaping – precise when required, musical when pushed. ⤵️

Quagliardi ColorBox Active DI: Clean Signal, Optional Colour

The Quagliardi ColorBox Active DI expands the ColorBox family with a fully discrete, high-headroom active direct box designed for pristine capture and flexible tone. Powered by a ±16 V split supply and built around legendary 2520 op-amps, it delivers fast transient response, exceptional clarity, and ultra-low distortion.

For moments when transparency alone isn’t enough, the CREAM colouration circuit introduces smooth, musical harmonic richness without obscuring detail. A buffered unbalanced output adds routing flexibility, making the ColorBox Active DI equally at home in studio or live environments where signal integrity matters. ⤵️

Quagliardi Channel Strip: A Complete Analogue Signal Chain

The Quagliardi Channel Strip brings together the 501+ Preamp, 576 FET Compressor, and 523 ParaShelving EQ into a unified 1U horizontal 500-series system housed in the PowerGrid Trio chassis. Designed as a complete front-to-back analogue workflow, it delivers everything from pristine gain and transformer saturation to fast, musical compression and refined tonal control.

Built around premium components – including permalloy transformers, 2520-style op-amps, and classic FET compression topology – the Channel Strip offers unmistakable analogue depth with modern flexibility. Ground Lift and Feed linking simplify internal signal flow, while the external power supply ensures stability and performance. It’s a flagship solution for engineers who want control, character, and cohesion in a single rack space. ⤵️
