Spectra 1964 STX500 500 Series 2-band Passive Equalizer

Spectra's legendary sound, found on iconic records from John Lennon's Imagine to Springsteen's Born to Run, lives on with the STX 500—a rebirth of the classic Model 500 2-band passive equalizer. Ideal for adding thick, punchy lows to basses and kicks, or shimmering highs to vocals and acoustic instruments, the STX 500 offers a versatile tonal palette for modern recording. With four frequency centers per band, up to 12dB of boost/cut in 2dB increments, and a design that introduces virtually zero distortion or phase shift, it seamlessly integrates with the STX 100 preamp for authentic, rich analog sound. Built in the U.S. with over 95% of components sourced from U.S. or European suppliers, the STX 500 offers the sound of vintage studios like Stax and Ardent right at your fingertips. Note: The STX 500 is designed to connect directly to the STX 100 preamp and cannot be used standalone.
