Application guide
You can take advantage of the R-4 Pro’s ability to record four channels simultaneously. You can use
channels 1 and 2 to record a stage performance via digital inputs, and channels 3 and 4 to record the sounds
of the room or audience via mics.
Panel settings
Recording Setup
These settings are useful when you cannot afford mistakes, such as when recording an event or other non-
repeatable occasion. Even if the input levels are set appropriately, there may be cases in which an
unexpectedly loud sound causes clipping to occur, or conversely, in which the sound stays at an
unexpectedly low level.
For these situations, use four mics and pair two for each channel. Set each input level to a different level,
and record all four channels (two stereo pairs) simultaneously. After recording, select an appropriate
project.

Recording Setup
Simultaneously recording environmental sounds (ambience)
Phantom power switch ON if using a condenser mic that requires phantom power; otherwise OFF
Input Select Dig + Ana
Set to Dig+Ana to use the XLR input connector and the digital
input connector simultaneously.

If using a computer to edit the waveforms after recording,
you may wish to use a higher sampling frequency.
Rec Bit 16 bit
Rec Mode STEREOx2
Set to STEREOx2 to record both the stage performance and
the ambient sounds in stereo.
Pre Recording OFF, 1–29 sec Specify the pre-recording time as desired.
Project Name Date, Name
Specify a name that will help you manage the projects when
recording is finished.
Date... Using the Date setting makes it easy to tell the date and
time that the recording was made.
Name... Assigning a unique project name, so that the projects
have names such as SCENE001, SCENE002, and so forth,
makes it easy to see which projects belong together.
Simultaneously recording at different input levels
Phantom power switch ON if using a condenser mic that requires phantom power; otherwise OFF
Input level knobs
Set channels 1 and 2 to appropriate levels. Set channels 3 and 4 to slightly low-
er input levels; for example, about -12 dB lower than channels 1 and 2.
