WARNING
Concerning the Auto O function
The power to this unit will be turned o
automatically after a predetermined amount
of time has passed since it was last used for
playing music, or its buttons or controls were
operated (AUTO OFF function). If you do not want the
power to be turned o automatically, disengage the
AUTO OFF function (p. 19).
WARNING
Use only the supplied AC adaptor and the correct
voltage
Be sure to use only the AC adaptor supplied
with the unit. Also, make sure the line voltage
at the installation matches the input voltage
specied on the AC adaptor’s body. Other AC
adaptors may use a dierent polarity, or be designed
for a dierent voltage, so their use could result in
damage, malfunction, or electric shock.
Use only the supplied power cord
Use only the attached power cord. Also, the
supplied power cord must not be used with
any other device.
CAUTION
Handle the ground terminal carefully
If you remove the screw from the ground
terminal, be sure to replace it; don’t leave
it lying around where it could accidentally
be swallowed by small children. When
refastening the screw, make that it is rmly fastened,
so it won’t come loose.
Precautions concerning use of phantom power
supply
Always turn the phantom power o when
connecting any device other than condenser
microphones that require phantom power.
You risk causing damage if you mistakenly
supply phantom power to dynamic microphones,
audio playback devices, or other devices that don’t
require such power. Be sure to check the specications
of any microphone you intend to use by referring
to the manual that came with it. (This instrument’s
phantom power: 48 V DC, 10 mA Max)

How the RC-600 Is Organized
Track
Tracks are used for recording and playing back audio from a
microphone or a musical instrument.
You can combine tracks 1–6 when using this unit.
Input FX, Track FX
Eects that are applied to the input audio are called “input FX”,
and eects that are applied to the tracks are called “track FX”.
You can register 16 input/track FX (4 banks x 4 types) to the
buttons and use them.
Rhythm
In addition to playing back tracks 1–6, you can also play rhythms
with this unit.
You can record while listening to a rhythm at the tempo you
specify.
Memory
The settings for tracks 1–6 together with the input FX/track FX and
rhythm are collectively called a “memory”.
You can store up to 99 memories with this unit.
System settings
Settings that are common to the RC-600 overall such as the
display contrast, USB and MIDI settings are called “system
settings”.

For details on each of the MIDI setting parameters, refer to “Parameter Guide” (PDF).
Controlling an External MIDI Device from the RC-600
Overview Explanation
Transmitting tempo data and data for starting and stopping playback
The RC-600’s performance tempo
data is transmitted to external
MIDI devices as MIDI Clock.
Setting an external MIDI device to the same tempo as the RC-600
MIDI Clock messages are output from the RC-600 at all times.
Set the external MIDI device beforehand so it is ready to receive MIDI Clock and MIDI Start and
Stop messages. For details, refer to the owner’s manual of your device.
Playback start and stop operations
with the RC-600’s switches can be
transmitted as MIDI Start and Stop
messages.
Transmitting Start/Stop
A MIDI Start message is transmitted at the moment that recording or playback of the track begins,
when tracks had been stopped. This message is also transmitted when an All Start is carried out.
A MIDI Stop message is transmitted when tracks have stopped. This is also transmitted when All
Stop is carried out.
* If you want MIDI synchronized performance to continue even after the track stops, set the
RHYTHM parameter STOP TRIG (p. 16) to “OFF”.
* Tracks whose 1SHOT setting (p. 15) is “ON” and tracks whose LOOP SYNC SW setting (p. 15) is
“OFF” will not transmit Start/Stop data.
Transmitting Program Change messages
When a memory is selected with
the RC-600, a Program Change
message corresponding to the
selected memory number is
transmitted simultaneously.
Transmitting Program Change messages
When memories are switched on the RC-600, a MIDI Program Change message is transmitted to
the connected external MIDI device. You can transmit Program Change messages numbered 1
through 99, corresponding to the 99 individual memories 01–99.
* Set “PC OUT” (p. 19) to ON beforehand.
* Program Change messages 100–128 cannot be transmitted.
* Bank Select MIDI messages (Control Change #0, #32) cannot be transmitted.
Transmitting Control Change messages
Operating information for the
RC-600’s switches, buttons, knobs,
and an external expression pedal
or footswitch is transmitted as
Control Change messages.
Transmitting Control Change messages
If you select a Control Change as the “ASSIGN” (p. 18) target, you can transmit MIDI control
change messages by operating the buttons and knobs on the RC-600, or by using an external
footswitch or expression pedal (connected to the CTL 1, 2/EXP 1 jack or the CTL 3, 4/EXP 2 jack).

22
Controlling Devices via MIDI

The RC-600 will synchronize to the
tempo of MIDI Clock data from an
external MIDI device.
Setting the RC-600 to the same tempo as an external MIDI device
Make settings on your external MIDI device so that it will transmit MIDI Clock and MIDI Start/Stop
data. For details, refer to the owner’s manual of your device.
Set the RC-600’s SYNC CLOCK (p. 19) to “AUTO”.
* You can’t switch the tempo during recording.
Start/stop data will be received
from an external MIDI device to
play/stop the RC-600.
Receiving MIDI Start
When MIDI Start (FA) is received, all tracks will play (All Start).
Switching memories
The RC-600’s memories switch
simultaneously upon receipt of
corresponding Program Change
messages from external MIDI
devices.
Switching memories
You can switch the RC-600’s memories with Program Change messages from external MIDI devices.
You can receive Program Change messages numbered 1 through 99, corresponding to the 99
individual memories 01–99.
* Program Change messages 100–128 cannot be received.
* Even if received, Bank Select MIDI messages (Control Change #0, #32) are disregarded.
Receiving Control Change messages
The RC-600 can be controlled
using Control Change messages
from external MIDI devices.
Receiving Control Change messages
You can use Control Change messages from an external MIDI device to control functions that
would be dicult to control using the RC-600’s own controllers.
In the “ASSIGN” (p. 18) setting, set SOURCE to “MIDI CC#1–#31, CC#64–#95”, and select the
parameter that you want to control in TARGET.

Troubleshooting
Problem Items to Check Action
Problems with sound
No sound/insucient
volume
Is this unit properly connected to other devices? Check the connections to other devices (p. 7).
Is the power to the connected amp or mixer not
turned on, or is the volume turned down?
Check the settings for connected devices.
Is there a short in one of the connection cables? Try replacing the connection cable.
The [OUTPUT LEVEL] knob have been lowered? Adjust knob to suitable position.
Is the input/output level set correctly?
Adjust the input/output levels on the MIXER screen for the input/output
jacks and connectors respectively.
Are the levels for tracks 1–6 set correctly?
Check the “PLAY LEVEL” setting for each track (p. 15).
Check whether an external expression pedal or other accessory has
been set to adjust the levels (p. 18).
Are the audio output destinations for tracks 1–6
set correctly?
Check the “ROUTING” settings in OUTPUT on the MENU screen (p. 18).
Has anything been recorded to the tracks?
Check the REC/PLAY indicator for each track to see whether the
track has been recorded. If a track’s button is unlit, nothing has been
recorded on that track.
No rhythm sound
Is the rhythm volume set correctly? Check the “RHYTHM OUT” setting on the MIXER screen.
Is the output destination for the rhythm sound
set correctly?
Check the RHYTHM settings in “ROUTING”, found in OUTPUT on the
MENU screen (p. 18).
Sound is missing from
the beginning and end
of a recorded track
To prevent noise, a fade-in and a fade-out are applied at the beginning and end of a recording. In some cases, it may sound
as if some of the sound has been cut out.
Unable to hear sounds
from devices connected
to the MIC IN 1, 2
connectors/INST IN 1, 2
jacks
Is the audio output destination set correctly?
Check the MIC 1/MIC 2/INST 1/INST 2 settings in “ROUTING”, found in
