With balanced I/O for standalone use, new level knobs, and internal enhancements over the original version, the Golden Age Project EQ-73 MKII is a 3-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 traditional operation with professional outboard gear, while its 1/4" TRS insert jack provides unbalanced connectivity for easy insertion into insert jack-equipped Golden Age Project gear or other unbalanced audio equipment.
Built in the style of a classic 1073 EQ module, the EQ-73 MKII's Class-A circuit has stepped frequency controls that reach from 20 Hz to 24 kHz, a dual inductor-based midrange bell-type band, and shelving filters for the low and high bands. Apply generous gain to each band—the low and mid bands have ±15 dB, while the high band has ±18 dB— and bypass individual bands via the dedicated EQ in/out switches between each band's frequency and gain controls.
- IC-based I/O section with balanced connections
- Supports standalone operation
- New knobs for the level controls
- Small coupling caps in parallel with all electrolytic caps in the IC-based I/O section
- Vintage-style electronic components
- Similar to the EQ section in the classic 1073 module, minus the high-pass filter
- Tantalum capacitors in the signal path
- External power supply helps avoid interference with the audio circuits
- Selectable ground-lift jumper
- Durable build quality
- Three bands with dual inductor-based midrange band
- Stepped selection of frequency bands
- Frequency selections from 20 Hz to 24 kHz
- Up to 15 dB of boost/cut for low and midrange bands, up to 18 dB of boost/cut for high band
- Low and high bands are shelving filters, midrange band is bell type
- Bypass switch per band
- Balanced XLR-1/4" combo input, and XLR and 1/4" TRS balanced outputs for line-level operation
- Unbalanced input and output connections via 1/4" TRS insert jack with nominal working level of approximately -18 dBu
- Works as a standalone EQ, or with Golden Age Project models equipped with insert jacks
- Compact, half-rack width
- Desktop friendly
- Can be rack-mounted with a Golden Age Project Pre-73 preamplifier via a UNITE rack kit (both available separately) for a 19" 1073-style signal chain
