The Accuphase C-3900 incorporates a particular connection designed to bypass its inner preamplification stage. This enter permits customers to combine an exterior sign processing unit, corresponding to a devoted phono stage or one other preamplifier, straight 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 would possibly make use of a specialised phono preamplifier recognized for its distinctive efficiency with vinyl data 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, doubtlessly minimizing coloration and maximizing the sonic constancy of the exterior unit. Traditionally, such options have catered to fans who admire modular audio programs and the flexibility to optimize every element for a selected activity.
