SPL - Qure
Dual-channel parametric 3-band EQ for demanding applications. (Model #9738)
The Qure is a 2-channel, parametric, 3-band EQ, ideally suited for demanding tonal shaping of individual instruments, voices and complex musical signals. Mastering applications benefit from a unique tonal potential and sophisticated filter designs.
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.
