The Roland SRV-3030D is a 1U rackmount, 24-bit digital reverb processor that served as a high-quality effects unit in studios and live sound rigs. As a successor to older Roland reverb units, it features two independent reverb engines that can be used in series or parallel. A standout feature is Roland's proprietary Dynamic Separation Algorithm, which intelligently processes different sonic elements of an incoming signal, like percussive and sustained sounds, through separate reverb engines for more complex and dynamic effects.
