Tascam DR-40 Owner's Manual

PEAK REDUCTION:
The input volume is reduced automatically to an appropriate 
level when excessively large signals come in. This allows input 
level setting to be performed easily.
The input level can be raised manually if required.

When recording live performances, for example, test for peak 
reduction may be performed before actual recording.
Select the peak reduction mode in recording standby, and 
maximize the input level.
As a test performance is given subsequently, the input gain 
for recording is reduced to an appropriate level to meet the 
input signals, and an optimum input level for the performance 
is set.
Recording will be stored at this input level if this mode is 
disabled before starting recording.
Otherwise, the input level will continue to be controlled 
automatically during recording.
It is also possible to store the recording in the limiter mode 
after automatically setting the input level in the peak 
reduction mode.
AUTO LEVEL:
The input level is controlled automatically to increase or 
decrease the input level when the input signals are too small 

or too large, respectively. This mode is useful for recording at 
meetings. In this mode, the input level cannot be changed 
manually.
LIMITER:
This prevents distortion of sounds when excessively large 
input signals come in suddenly.
This mode is also suited for recording of live performances 
with large volume changes.
In this mode, the input level can be changed manually during 
recording.

Distortion of sounds may occur when excessively large 

• 

input signals come in even if the LIMITER function is 
activated. In such a case, lower the input level or keep 
proper distance between the unit and the source.
When using LINE input, the level controls have no effect. 

• 

This recorder has five recording modes. 
Use the 

REC MODE

 item on the 

REC MODE

 screen to set the 

recording mode. 
The settings available are different for each recording mode.
