SPL Qure

The Qure is ideally suited for demanding tonal shaping of individual instruments, voices and complex musical signals.

All applications benefit from the unique tonal potential and the sophisticated filtering design that perfectly complements the fine details of the sound being processed.

The highly sophisticated circuitry of the Qure forms the basis for its outstanding tonal qualities: each filter is serially connected on separate boards with individual op-amps, resulting in excellent noise and distortion values, with a hard bypass available for each individual filter.
