The QURE is a fully parametric equalizer, specially designed to
meet the most demanding studio applications. It is designed as 3-
band, two-channel system with input and output gain controls,
high-cut and low-cut filters as well as the new QURE-circuitry for
the creative and corrective sound shaping of vocals, instruments
and complex stereo material. Both balanced XLR and balanced
stereo jacks are provided for signal connections to and from the
QURE.
Its musically optimized parametric filters, based on a sophisticated refinement of state-variable-filter technology (SVF), include
proportional bandwidth, tube technology for a warm and fat
sounding mid-range, LC filtering for clear and transparent upper
frequencies, transistor and semi-conductor technology for a volumious low end.
The proportional-Q principle provides precise control over a
frequency range, from 15 Hz to 21 kHz, while the low noise level of
-99 dB (A-weightened), and the enormous dynamic range of
113 dB, make the QURE ideally suited for mastering and cutting. By
employing circuitry designed around the principles of perceived
sound, rather than simply designing by numbers, the QURE overcomes the limitations of conventional parametric equalizers.
The QURE circuitry
The QURE circuitry is a new SPL development which gives the
name for the unit and also represents a new technology, which
uses coils to increase the presence of vocals and the depth of the
music. At the same time it is ideally suited to cure recordings from
digital harshness. The name is derived from ‘cure’ in combination
with Q from EQ.
The signal runs through a tube circuitry featuring a Sovtek
12 AX 7 double triode tube in a mixed current/voltage coupling
mode. This stage is extremely clip-resistant and produces a pleasant and musical sounding tube-THD spectrum.
The QURE ON switch puts a coil/condenser/resistor filternetwork (LCR) into the tube output stage. This network is integrated
into the coupling path of the tube and reacts on the dynamic
reponse of the input signal by influencing THD spectra and phase
response. The QURE potentiometer changes the frequency
response and produces a fresh and silky top-end and a mid-range
free of sharpness and harshness. The presence and ‘aura’ of vocals
is largely improved.
