Step 1: menu>input>mic gain LOW
Step 2: hold DUAL button down; mode: LINE (I normally set level to 100 (don’t go lower than 95 I think)
Step 3: input level buttons on side of recorder adjust mic input gain; set no lower than 67. You can raise this on the fly as necessary.
(If a soft/acoustic situation, setting INPUT level to MED may be necessary. Sound check recommended) Of course depending on your set up you might adjust gain with whatever you are feeding your mics with)
During recording pushing DUAL button will toggle between mic and line levels on display.
Happy recording!
