Golden Age Audio EQ-81 MKIII 4-Band Equalizer

What is the Golden Age Project EQ81 MKIII 4-band Equalizer?
The Golden Age Project EQ81 MKIII is a 1-channel, 4-band analog equalizer that offers vintage-style sound at a fraction of the cost of its high-end counterparts. Designed with a class-AB equalizer circuit based on the legendary 1081 module, the EQ81 MKIII delivers the warm, musical, and punchy character that has made the 1081 a favorite among sound engineers. The MKIII version brings enhanced features, including stepped frequency controls, more versatile EQ bands, and upgraded connections, making it an ideal tool for anyone looking to add that classic, vintage EQ sound to their recordings.

Vintage Sound with Modern Updates
The EQ81 MKIII delivers the sought-after vintage tone that has defined countless iconic recordings. By using vintage-style electronics with no integrated circuits in the signal path (when the insert connector is in use), this equalizer offers a warm, natural sound free from the harshness of modern IC-based designs. Tantalum capacitors in the EQ signal path further enhance the tonal integrity, ensuring you achieve the same rich, full-bodied sound that made the 1081 such a revered EQ. Whether you are mixing vocals, instruments, or full tracks, the EQ81 MKIII brings a musical character that enhances every sound it touches.

Incredible Flexibility with 4 Bands and Stepped Controls
The EQ81 MKIII features a versatile 4-band EQ with switchable shelving for bass and treble, and bell-type filters for the mid frequencies. This allows for precise control over each band, with a wide frequency selection range from 33Hz to 15kHz. The stepped frequency controls ensure easy recall of your favorite settings, making it perfect for multi-unit use in stereo applications. The control range for each band is +/-18dB, with an off mode for each band that provides even more flexibility in shaping your sound. Whether you need to add warmth to your low-end or brighten your highs, the EQ81 MKIII allows you to make quick, efficient adjustments with full precision.

Standalone or Integrated for Maximum Versatility
The EQ81 MKIII is incredibly versatile, functioning as a standalone equalizer for a variety of sources. It is equipped with a TRS jack for INSERT mode in-and output connections, offering a nominal working level of -18dB. This flexibility makes it a perfect fit for recording instruments, vocals, or any audio source where you need precise EQ adjustments. Additionally, it can be paired with the Golden Age PRE-73 preamp using the insert jack for even more tonal shaping options. When combined with the Pre-73, the EQ81 MKIII can help you build a full 1081-style unit, providing classic British EQ tones at a much more affordable price.

Enhanced Build Quality and Practical Features
The EQ81 MKIII comes with several improvements over its predecessor. The upgraded knobs offer a more defined grip, providing a solid and reliable feel when making adjustments. The unit also includes a selectable ground lift jumper, which disconnects the audio signal from the chassis ground to prevent hum and noise. For even better performance, the EQ81 MKIII features an external 230V power supply that isolates the audio circuitry from the power source, ensuring clean and noise-free operation. These enhancements make the EQ81 MKIII a durable and highly functional tool for any studio setup.
