The Spectra 1964 STX 500: A Modern Relic Mirroring the Classic Model 500 Equalizer

The Spectra 1964 STX 500 is a meticulously crafted reimagining of the iconic Model 500 two-band passive equalizer. Specifically engineered to seamlessly integrate with the new STX 100 preamp, this unit delivers vintage tonality with the convenience of modern features, all in a budget-friendly, compact design.

Intuitive Controls for Rapid Adjustments

Outfitted with dual bands of selectable shelving EQ, the STX 500 excels in swiftly enhancing your tracks with radiant highs or resonant lows. Each band provides four preset frequencies, with adjustments available in 2 dB steps up to a 12 dB boost or cut—making recall a breeze. Frequencies for the high band range from 2.5 kHz to 15 kHz, while the low band covers 50 Hz to 200 Hz. Custom-tuned slopes ensure that the equalizer captures the characteristic sonic fingerprint of the original unit.

A Harmonious Duo

Designed to synergize perfectly with the STX 100 preamp, the STX 500 transforms into an active feedback element when paired, offering unmatched versatility. Both units employ Spectra’s cutting-edge design, ensuring zero signal degradation and negligible distortion when making EQ adjustments.
