Note:
• Always connect the AC adapter to the mixer before
you connect it to AC power. When you finish,
disconnect the adapter from AC power before you
disconnect it from
the mixer.
• Using an adapter that does not meet the
specifications could damage the mixer or adapter.
Setup
Preset the Mixer
Important!
To prevent accidental audio mixing or channel overdrive,
set MONO/STEREO to MONO, set POWER ON/OFF to
OFF, and slide Channels 1–4 to 0 before you connect to
your power supply.
A sudden high output from the mixer could damage
audio devices connected to the mixer and could damage
your hearing, especially if you use headphones.
Preset Audio Devices
Turn off all devices before you connect them to the mixer.
To avoid sudden sound outputs from connected audio
devices, adjust the volume of the connected audio
device to their lowest levels.
