RSP Technologies is a professional audio signal processing brand established in the early 1990s by Rocktron, the Michigan-based effects manufacturer founded by Bob Waller in 1983. The RSP Technologies name was created to distinguish a line of studio-oriented rack equipment from Rocktron's guitar-focused product range, and the operation has long been based in Rochester Hills, Michigan.

The brand's catalog centers on rack-mount processors built around its proprietary HUSH noise reduction technology, a downward expander/dynamic filter system also licensed across Rocktron products. Notable units include the Intelliverb, a 24-bit multi-effect processor offering Virtual Room reverberation, pitch shifting, chorus and integrated HUSH; the Saturator, a dual-channel 12AX7-based tube warmth and compression unit aimed at digital recording; the 4-Channel Studio Gate; and additional products such as Project X (an automated digital mixing system), Reanimator, Emphasis (a studio headphone distribution system) and the Circle Surround 5.2.5 surround processor.

RSP Technologies products are most often encountered in project and professional studios, where the Saturator and Intelliverb in particular have a following on the secondary market. Rocktron, and the RSP Technologies line with it, was acquired by GHS Corporation in 2000.

RSP has 3 products cataloged on Equipboard, including Effects Processors. Their gear is featured by 3 artists, with the strongest followings in Rock and Metal. Notable users include Kevin Parker, Alexi Laiho, and Roope Latvala.
