Product description Designed for stereo or dual mono applications, the Qure from SPL is a three-band parametric equalizer replete with input/output controls, high- and low-cut filters, and a proprietary Qure control which facilitates an enhanced sense of presence-both in mono and stereo instruments-while simultaneously reducing the harshness often associated with incorrectly achieved performances in the digital realm.
This EQ provides balanced XLR and 1/4" jacks for inputs and outputs, as well as a proportional-Q principle for precise manipulation of frequencies between 15 Hz and 21 kHz. Furthermore, its dynamic range of 113 dB renders the Qure quite useful at the mastering stage of any production. - Tube Functionality
- The Qure employs tube circuitry featuring a 12AX7-LPS double triode valve in a mixed current/voltage coupling mode. This stage is clip-resistant and produces a musical tube-THD spectrum.
- Proportional-Q
- Conventional constant-Q designs keep the amplitude of a signal constant, regardless of the adjusted bandwidth. This often results in unmusical boosting of frequencies ancillary to your specific target. Proportional-Q, however, reduces the amplitude of a processed frequency band as the bandwidth broadens. As such, there is no need to constantly readjust the boost/cut control when varying the bandwidth.
- Other Notable Features
-
- Proportional-Q operation.
- Variable HF and LF cut filters.
- Variable input gain (-12 dB to +18 dB).
- Variable output gain (-7 dB to +4 dB).
- Hard-bypass for each filter band and both cut filters.
- Master relay hard-bypass for entire unit.
- Stepped potentiometers throughout for easy recall.
- Central grounded shield layout.
- Toroidal transformer power supply.
