Vintage-flavored compression and preamp versatility in a 500 series module.

The Spectra 1964 STX 600 brings the iconic sound of the 601 Complimiter circuit to a compact, affordable 500 series format, perfect for engineers seeking vintage performance with modern convenience. At its core is the legendary 601 Complimiter, introduced in 1969, which offers the fastest analog compression and limiting available, enhancing headroom while reducing noise and distortion. With 62dB of gain, the STX 600 functions effectively as both a microphone and line preamp, featuring switchable 48V phantom power and phase control for added flexibility. True to the Complimiter legacy found in the original 610 and newer C610 and V610 models, the STX 600 combines ultrafast attack times—less than 90 nanoseconds for limiting—with smooth, high-fidelity sound across a broad frequency response. This modern addition to Spectra's lineup ensures the renowned Complimiter performance in a streamlined, versatile design suitable for any professional studio.
