The Accuphase C-3900 encompasses a particular connection designed to bypass its inner preamplification stage. This enter permits customers to combine an exterior sign processing unit, reminiscent of a devoted phono stage or one other preamplifier, instantly into the sign path. Primarily, it supplies a direct conduit to the C-3900’s quantity management and subsequent amplification phases, successfully using the C-3900 as a high-quality management amplifier.
This function enhances system flexibility and permits for sonic tailoring primarily based on consumer choice or the precise traits of the supply materials. For example, audiophiles may make use of a specialised phono preamplifier identified for its distinctive efficiency with vinyl information after which route that sign by means of the designated enter. The profit lies in bypassing the built-in preamplifier circuitry of the C-3900, probably minimizing coloration and maximizing the sonic constancy of the exterior unit. Traditionally, such options have catered to lovers who respect modular audio programs and the power to optimize every element for a particular job.
