In addition to directing the internal gain settings and balance requirements of the DMC-30, microprocessor systems also control various features and housekeeping functions. Software control of the motorized volume fader makes possible a progressive ramp-up function for the mute control. Available rate selection allows fader control speed o be adjusted by the user. A remote operated reset function allows all preamplifier modes and functions to be bypassed and reset to start-up positions with one button. Unlike embedded processors in conventional preamplifiers, DMC-30 programming software is fully upgradable.
Removable memory allows easy feature revision as future software developments occur.
For service and upgrade, even the main signal buss and power supplies are incorporated on the removable Systemboard assembly. Front panel control commands and future options are also updated easily in the field via the removable DMC-30 software module. Spectral's engineering focus on preamplifier development for over two decades reflects a keen awareness of the major impact this crucial component makes. In keeping with its role as the reference heart of the most ambitious music systems, every DMC-30 represents the absolute summit of materials and workmanship. The exhaustive testing and burn-in standards employed by Spectral in its production are unparalleled in the audio industry.
