● sensitivity/Input level knobs
These knobs adjust sensitivity/input levels.
When recording in stereo x2, these knobs control the following signals.
Channel 1STEREO 1 L-channelSENS/INPUT LEVEL 1 knob
Channel 2STEREO 1 R-channelSENS/INPUT LEVEL 2 knob
Channel 3STEREO 2 L-channelSENS/INPUT LEVEL 3 knob
Channel 4STEREO 2 R-channelSENS/INPUT LEVEL 4 knob
Adjusting the input level
1.Turn the input level knob [SENS] (outer) all the way left.
2.Turn the input level knobs [LEVEL] (inner) to the center position. This signal is 0 dB.
3.Hold down the [PAUSE] button and press the [REC] button.
The R-4 Pro enters recording standby mode. During recording standby, the [REC] button 
blinks and the display alternates between REC and STANDBY.
4.Play the sound to be recorded into the microphone.
Gradually turn the input level knob [SENS] toward the right.
sensitivity has 11 steps of -56, -50, -44, -38, -32, -26, -20, -14, -8, -2, and +4 dBu.
* When the channel name display reverses, the input level has reached the clipping level. Set to the knob 
to the position just before the display reverses.
5.Adjust the level so that the level meter shown in the 
display reaches a point slightly before C (clip level). If 
the recording level is too low, quiet sounds will not be 
recorded. If the recording level is too high, soft sounds 
will be distorted, producing a crackling noise in the 
recording.
* If clipping occurs when adjusting SENS, clipping may 
occur even if the level meter does not reach the clip level. 
The channel name blinks in black and white
* The level meter displays the clip level (C) as 0 dBFS (FS = full scale). 
For example, 12 indicates -12 dBFS.

Caution regarding placement and handling while recording
The internal hard disk is a precision device. If you subject the hard disk to physical shock, such as the 
following, you may not be able to access the data on the disk, causing recording or playback to be 
unsuccessful. In the worst case, irreparable damage may occur.
Please avoid subjecting the R-4 Pro to strong impact or continuous vibration during use.
The following actions may cause malfunctions
• Subjecting the unit to impact, such as dropping it from a table onto a hard floor.
• Subjecting the unit to continuous vibration, such as by leaving it on an uncushioned surface like 
the floor of a moving automobile.
