Introducing the R-4 Pro
Power connector [DC IN]
You can connect either the included power conversion cable or a commercially available cable for an 
external power device.
 Digital output connector [DIGITAL OUT]
This connector outputs a digital signal. You can digital devices, such as speakers or mixers, with an XLR 
type cable. This connector provides the same audio signal as the headphone jack (), but in digital form.
(AES/EBU, IEC 60958-4 compliant)
* Volume cannot be adjusted with the monitor level knob.
Digital input connector [DIGITAL IN]
If you want to record a digital signal, connect a XLR type cable to this connector. The digital input signal is 
recorded in stereo on channels 1L and 1R. If you want to record in monaural, you’ll need to change the Rec 
Mode setting in the System Settings menu. For details, refer to “1 Recording Setup” (p. 72). (AES/EBU, 
IEC 60958-4 compliant)
USB Storage connector [STORAGE ONLY]
You can connect commercially available USB external memory devices to this connector. You can backup 
projects recorded with the R-4 Pro to USB memory or USB hard disks.
For details on external memory devices, see Handling external memory device (p. 79)
Timecode Connector [TIMECODE]
You can connect devices with a timecode port. This allows you to records the timecode in the R-4 Pro when 
the recording starts (IN) and to output the R-4 Pro internal timecode (OUT). For details on recording the 
timecode, see Connecting to a video device with a timecode port (p. 84).

Headphone jack [PHONES]
You can connect a set of headphones with this jack. Use the monitor level knob () to adjust the 
volume. If you connect headphones, no sound is output from the internal speakers ().
Grounding terminal
927Depending on the circumstances of a particular setup, you may experience a discomforting sensation, or 
perceive that the surface feels gritty to the touch when you touch this device, microphones connected to it, 
or the metal portions of other objects, such as guitars. This is due to an infinitesimal electrical charge, which 
is absolutely harmless. However, if you are concerned about this, connect the ground terminal (see figure) 
with an external ground. When the unit is grounded, a slight hum may occur, depending on the particulars 
of your installation. If you are unsure of the connection method, contact the nearest Roland Service Center, 
or an authorized Roland distributor, as listed on the “Information” page.
Unsuitable places for connection
• Water pipes (may result in shock or electrocution)
• Gas pipes (may result in fire or explosion)
• Telephone-line ground or lightning rod (may be dangerous in the event of lightning)

XLR input connectors 1–4
These are analog audio input connectors compatible with mic preamps. They accept either balanced or 
unbalanced connections.
You can use XLR input connectors 1–4 as four channels of monaural input or as two stereo pairs, 1/2 and 
3/4. For details, refer to “1 Recording Setup” (p. 72).
* The XLR type connectors 1-4 can provide 48 V phantom power, allowing you to connect phantom-powered 
condenser mics. In this case, turn on the phantom power switch ().
fig.XLR-TRS922This R-4 pro is equipped with balanced (XLR) type connectors. Wiring diagrams for 
these jacks are shown below. Make connections after first checking the wiring 
diagrams of other equipment you intend to connect.
Line output jacks [LINE OUT]
These jacks output an analog audio signal. You can use RCA cables to connect powered speakers, audio 
equipment, mixers, and other devices. 
The regulated output level is fixed at -10 dBu.
* The volume for each channel during playback can be adjusted on the mixer screen (p. 19).
* Line output can be output as 4-indiv or monitor. See “5 System Setup” in System settings (p. 75) for details.

Channel names
D is play s up to four  cha n nel na mes . If you’re using one stereo channel, 1L and 
1R are shown. If you’re using two stereo channels, 1L, 1R, 2L, and 2R are 
shown.
For monaural project, 1, 2, 3, and 4 are shown according to the number of 
channels.
When the sensitivity setting is too large and clipping occurs the display is 
shown in inverted black and white.
Output assignments
The output assignments show how the audio of each channel is assigned to 
the L/R output channels. L means that the audio is output to the left channel, 
R to the right channel, and LR to both left and right channels. Channels that 
are not shown are not output. From the main screen, you can use the [CUR-
SOR] up/down buttons to select the channel that you want to monitor.
The output is sent to the PHONES jack, line output jacks, and digital output 
connector.
*When Output Sel (p. 75) in the system settings is set to "monitor," the 
line output jacks output sounds as set in the output assignments.
