Chapter 8. Interfacing and Processing
8.1. The Input
For the user, “the input” is often just a socket—often one groped for amidst a tangle of leads. This chapter untangles the details of the rarely recounted considerations that lie behind audio power amplifier input sockets that enable the signal source to connect to the amplifier (and maybe to many amps) with the least loss of fidelity and without introducing unwanted noise.
The amplifier is treated as a whole without considering the power capability or type of the output section.
8.1.1. Input Sensitivity and Gain Requirements
Input sensitivity is the signal level at the input needed to drive an amplifier up to its full capability, to just before clip, into a stated, nominal ...
