mportant Notes on Making Connections
and Switching the Power On and Off
• To prevent malfunction and/or damage to speakers
or other devices, always turn down the volume, and
turn off the power on all devices before making any
connections.
• This instrument is equipped with balanced (TRS)
type jacks. Wiring diagrams for these jacks are
shown below. Make connections after first checking
the wiring diagrams of other equipment you intend
to connect.
fig.XLR/TRSJack.eps
• When connection cables with resistors are used, the
volume level of equipment connected to the inputs
(INOUT jacks) may be low. If this happens, use
connection cables that do not contain resistors.
• Depending 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)
• Once the connections have been completed, turn on
power to your various devices in the order specified.
By turning on devices in the wrong order, you risk
causing malfunction and/or damage to speakers and
other devices.
(When turning the power off, reverse this procedure.)
Connected device

Power amp, etc.
• This unit is equipped with a protection circuit. A
brief interval (a few seconds) after power up is
required before the unit will operate normally.
• To avoid risk of electric shock, do not touch the
connectors while the unit is in operation.
• Never remove a card during recording of phrases.
Furthermore, do not turn off the power or remove
the AC adaptor cord during recording of phrases.
Doing so may damage the card.
• To avoid the risk of malfunction and/or damage,
insert only CF Card into the disk drive. Never insert
any other type of disk. Avoid getting paper clips,
coins, or any other foreign objects inside the drive.
• The pin assignment for the connectors is as shown
below. Before making any connections, make sure
that this pin assignment is compatible with that of all
your other devices.
Turning On the Power
The AR-200R is not equipped with a power switch.
Power is turned on when electricity is supplied to the
power connector (for the supplied AC adaptor), or to the
control input and DC input, or control I/O connectors’
DC IN (p. 8).
Supplied AC adaptor: PSB-1U
Control input and DC input/control I/O connector
specifications
Voltage: 9 to 24 V DC
Current: 1200 mA
*
Do not supply electrical power simultaneously to multiple
connectors or terminals; doing so may result in damage to the
unit.
