Caution!
High sound level
Before making any connections or disconnections, make sure to set the corresponding level
controls in the fully counterclockwise position -∞.

Microphone/line input

Electronically balanced INPUT 1/2 MIC/LINE for the connection of a line level signal source
(such as mixer etc.) or a microphone. Phantom power can be enabled (see menu item

Establishing a connection is possible via TRS or XLR-type plugs. Whenever possible, balanced
signal feed is always preferable to guard against potential noise or HF-interference.
