Classic British EQ Sound in a Convenient Format
The 73EQ JR is a faithful recreation of the legendary British console EQs of the 1970s, offering broad-strokes equalization with the warmth and character only a Class A circuit can provide. Its high and low bands are Baxandall-style shelving EQs, known for their smooth, musical response. Whether you need to add more sparkle to your high frequencies or tighten up your low-end, the 73EQ JR makes it easy to sculpt your sound. The midrange band is a fixed-Q, dual-inductor-based design, providing a distinctive, vintage flavor that gives your tracks that famous "punch" and "air" that vintage EQs are known for.

Versatile Tone-Shaping Controls
The Heritage Audio 73EQ JR features a highly versatile EQ section with a high-frequency shelving filter that offers up to +/- 16dB of gain, with selectable frequencies at 10kHz, 12kHz, 16kHz, or 20kHz. This range of frequencies allows you to fine-tune the high end, from adding shimmer to brightening up your mix. The low-frequency shelving filter is equally flexible, offering up to +/- 16dB of gain, with selectable frequencies at 35Hz, 60Hz, 110Hz, and 220Hz. This makes it perfect for tightening up the low end or adding warmth to bass-heavy tracks. The mid-frequency band is a peaking filter, allowing you to boost or cut with precision at selectable frequencies, including 0.36kHz, 0.7kHz, 1.6kHz, 3.2kHz, 4.8kHz, and 7.2kHz, offering a wide range of tonal possibilities.

Quality Components for Classic Sound
The 73EQ JR is built with the highest-quality components to ensure that you get the best possible sound from your recordings. It features Carnhill transformers, known for their ability to add richness, warmth, and harmonic distortion to any signal. The Marconi-style knobs offer precise control over your settings, providing an intuitive, tactile feel that makes it easy to dial in the perfect sound. The Class A, single-ended output stage ensures that you get high-headroom performance, delivering clean, clear audio without clipping or distortion.

Compatibility and Power Supply
The 73EQ JR requires a compatible 500 Series chassis for operation, making it ideal for those who are already working within the 500 Series format. It features an internal slow-turn-on +24v power supply, which reduces inrush current, improving the performance of your lunchbox or rack system. This thoughtful design ensures that your 500 Series rack is working at peak performance while delivering the vintage-inspired sound that only the 73EQ JR can provide.
