SPL Qure Model 9738 Parametric Three-Band Tube EQ 2 Channel Qure Function
Dual-channel parametric 3-band EQ for demanding applications. (Model #9738)
SPL Qure Model 9738 Parametric Three-Band Tube EQ 2 Channel Qure Function
The Qure is a 2-channel, parametric, 3-band EQ, ideally suited for demanding tonal shaping of individual instruments, voices and complex musical signals. Mastering applications benefit from a unique tonal potential and sophisticated filter designs.
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
