[QUOTE="Jepalan, post: 8157089, member: 655519"] I respectfully disagree, point for point, with almost everything you wrote above. 1) O-scopes are used for gain balancing in all kinds of professional audio installs, including high-end home audio, concert halls, and studios. 2) The point of gain setting is to:match speakers AND to optimize signal to noise ratio through the system, AND to set peak levels to the *desired* clipping point 3) In my *opinion* a reputable shop should own an O-scope, know how to use it properly, and use it on every install to set gains. 4) There are many things that can go wrong when setting only by ear (and many things that can be corrected by a critical ear). In my opinion, o-scopes and DMMs ensure you are starting with the optimal baseline before using the ears to fine tune everything. For example, it is can be difficult to set optimal signal levels when multiple devices are being daisy chained (like LOC to DSP to AMP) and they all have gain or input pots. [/QUOTE]
