Product description The Golden Age Project EQ-81 MKII 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 at +4 dBu operating level, 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 MKII'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. The EQ-81 MKII is powered by the included external power supply, which inhibits interference between the audio and power circuits. Its half-rack width makes it desktop friendly, and allows it to be rack-mounted with a Golden Age Project Pre-73 preamplifier via a UNITE rack kit (both available separately) for a 19" 1081-style signal chain. - Vintage-style electronic components
