Qure Parametric EQ
Qure Parametric EQ Qure Parametric EQ


The Qure is a 3-band fully parametric equalizer. The Qure tube circuitry enhances the presence and imaging of vocals, instruments and complex stereo material. The Qure is designed as an EQ with 'sound'. Coil filters and the proportional-Q principle contribute to the musicality of this EQ while the low noise of -99dB and the huge dynamic range of 113dB make it suited as mix bus and mastering EQ.

Producer and FOH-Engineer Michael Schwarzer (Donots, Sklaven, Independent) and SPL.
