to other menus by briefly pressing the INFO/SET button or go to SETTINGS menu by long pressing the
INFO/SET button.
Four PPM meters on the right and five parallelized/bridged indicators on the left are
permanently shown up on the display, no matter what menu is cycled through in the
middle on the display. The PPM meters show the output audio level for each channel of
the amplifier. The 0dBFS is aligned to the amplifier maximum output which means you
should never drive the input level, combined with the volume control and eXtraTone™
bass boost, over the 0dBFS. Otherwise, you hear an audible clip noise on the output of
the amplifier. There are clip hold indicators on the top of each PPM meter to bring up your attention if the
amplifier is overdriven. The 32 segments of each PPM is scaled from 0dBFS down to -60dB with each little
segment representing a 2dB difference in signal strength.
NOTE:
The analog input sensitivity to drive the amplifier to its 0dBFS maximum output is
configurable in SETTINGS menu. You can cycle through 0dBu, 1V, and 1.4V for sensitivity setting
while the factory default is set to 1.4V.
