by using the VU meter indicator on the LCD screen. If the
VU meter bar is solid or the system indicates LIMIT, the
input or source level is too high. Fore more information,
see System status, page 21.

input source. If the microphone is connected directly to

increases gain-before-feedback. See problem 6.
