Adjusting the input level
Before starting recording, input levels should be adjusted to
prevent recorded sounds or signals from being distorted due to
excessive input levels and to prevent them from being so low
that they are below the noise floor.
In addition to manual adjustment, the unit has two other level
adjustment functions: automatic level control and a limiter. Use
these as needed. (See “Using the Level Control Function” on
page 21.)
TIP
In addition to adjusting input levels, try changing the
distances and angles between the microphones and the
sound sources. The angles and distances of the microphones
can also change the character of the recorded sound.
CAUTION
Manual adjustment cannot be performed when the
automatic level control function is selected ( appears
to the right of the elapsed time on the recording screen). To
enable manual input level adjustment, turn the level control
function off or select a different mode. (See “Using the Level
Control Function” on page 21.)
