-. +4dBu/-10dBV Switch 14

Your AMX-120 provides the gain select switch, which is used to adjust the sensitivity of line input on stereo channels. Line level are considered to be between 1V and 2V RMS (+2dBu ~ +8dBu) in professional equipment, peak levels may extend to over 10V RMS (+22dBu). The accepted standard for sound reinforcement equipment is +4dBu.

Unfortunately, many low budget components fall short of these levels, so we need to "baby" their level, and find an- other source for the signal strength necessary to drive the power amplifiers, in such situations, the -10dBV operating level is compromised.

NOTE: The remaining controls of stereo channel are the same as in the mono channel section.
