SPL Qure
Dual-channel, parametric, three-band EQ
The
Qure is ideally suited for demanding tonal shaping of individual
instruments, voices and complex musical signals. All applications
benefit from the unique tonal potential and the sophisticated filtering
design that perfectly complements the fine details of the sound being
processed.
The highly sophisticated circuitry of the Qure
forms the basis for its outstanding tonal qualities: 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.
Features
- 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
- Central Grounded Shield Layout
- SPL's Super-Balancing Hybrids (CMRR > 80dB)
- Tube warm up circuitry for prolonged tube-life
- Overrated internal toroidal power supply
