The STX 100 represents an affordable alternative for employing the same Spectra Sonics technology of our famous recording desks made over 40 years ago. The unique circuit topology of the STX 100 utilizes a 100 series discrete preamplifier design that was at the heart of every console built by the company. The result is unequaled performance in terms of expanded dynamic range (headroom), low noise and distortion, as well as extended harmonic content of the amplified signal. The STX 100 is a high-quality product manufactured in the US by Spectra 1964 at our Ogden facility. (Over 95% of the sourced components within all Spectra1964 originate from the US or European suppliers).
