Description
With new level knobs and internal enhancements over the MKII version, the Golden Age Project EQ-81 MKIII is a 4-band equalizer that uses vintage-style electronics and Tantalum capacitors in the signal path to deliver classic tonality for musicians, producers, and audio engineers. Its balanced XLR and 1/4" I/O connectors enable standalone use, while its 1/4" TRS insert jack provides unbalanced, integrated circuit-free connectivity for easy insertion into insert jack-equipped Golden Age Project gear or other unbalanced audio equipment.
Built in the style of a classic 1081 EQ module, the EQ-81 MKIII's Class-AB circuit has stepped frequency controls that reach from 33 Hz to 15 kHz, inductor-based mid bands with hi-Q switches, and bass and treble bands with selectable shelving/bell modes. Apply up to 18 dB of boost or cut per band, and bypass individual bands via the Off position on each band's frequency selector.
What's New on the MKIII
- New knobs for the level controls
- Small coupling caps in parallel with all electrolytic caps in the IC-based I/O section
An Updated Take on a Classic
- Vintage-style electronic components
- Similar to the EQ section in the classic 1081 module, minus the high- and low-pass filters
- Tantalum capacitors in the signal path
- No integrated circuits in signal path when using the 1/4" insert jack
- External power supply helps avoid interference with the audio circuits
- Selectable ground-lift jumper
- Durable build quality
Four EQ Bands
- Four bands with inductor-based, switchable-Q, mid-frequency bands
- Stepped selection of frequency bands
