– Alsamixer and limiter settings
Software setup
›
Type alsamixer on the command line and acces the MA12070P
control mixer to set the protection limiter level of the device. Usually
a -15 dB setting will be a good starting point for 4 ohm nominal
impedance speakers. It is strongly recommended to go through the
user’s guide section, where this topic is covered, to correctly
configure the limiter threshold level. Press escape to exit the mixer.
