SPL Qure

The Qure is a fully parametric equalizer, specially designed to meet the most demanding studio applications. It is a 3-band, two-channel system with input and output gain controls, high-cut and low-cut filters as well as the new Qure control for the enhancing presence and room imaging of vocals, instruments and complex stereo material.

Both balanced XLR and balanced stereo jacks are provided for signal connections to and from the Qure.

The proportional-Q principle provides precise control over a frequency range, from 15Hz to 21kHz, while the low noise level of -99dB (A-weighted), and the enormous dynamic range of 113dB 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 equalisers.

• 2 x 3-band fully parametric EQ
• Proportional Q operation
• Variable HF and LF cut filters
• Unique QURE control
• Variable input gain (-12dB to +18dB)
• Variable output gain (-7dB to +4dB)
• Hard-Bypass for each filter band and both cut filters
• Master relay hard-bypass for entire unit
• Tube warm up circuitry for prolonged tube-life
• Easy recall thanks to stepped potentiometers
• Single op-amps are used throughout to minimize noise and THD
• Each filter is mounted on a separate printboard featuring a "central grounded shield layout’ (CGSL) for maximum rejection of interfering frequencies
