8. CONNECTIONS
We recommend turning off all devices or putting them into standby mode before
making audio connections, whether they are input devices such as audio sources or
devices connected to mixer outputs such as power amplifiers.
When connecting a new audio device to the mixer inputs, if the mixer is turned on, it
is recommended to set the channel volume control to minimum, and to increase this
value until a desired mix level is reached.
Failure to follow these recommendations may result in loud noises that could
damage the connected devices or your hearing.
