The Spectral Audio DMC-30 SV is a high-end stereo line-level reference preamplifier built around Spectral’s DMC-30 topology. It provides five single-ended RCA inputs, one balanced XLR input, and a tape-monitor loop, with both RCA and balanced XLR main outputs. Notable features include a motorized conductive-plastic output fader, relay-based balance attenuation with center bypass, selectable stereo/mono operation, absolute-phase inversion, high-level input trim, 50-step LED level and balance displays, extensive DC/oscillation protection, and the DMC-30R remote control. The available documentation identifies the product as an older model and does not indicate current production; it is best regarded as no longer manufactured, although unused and second-hand examples may still be available.
