Names of Things and What They Do
Set the [SETTING] switch to “GUITAR” or “MIC” unless
you’ve connected a condenser microphone that
requires phantom power.
Supplying phantom power to a dynamic microphone
will cause malfunction. For details on the specifications
of the microphone you’re using, refer to the owner’s
manual for your microphone.
Before you change the position of the [SETTING] switch,
set the volume to “0” using the [VOLUME] dial on the
side panel. If you change the position of the [SETTING]
switch while the volume is raised, loud noise may be
emitted, possibly damaging your amp and speakers.
[SENS] knob
This knob adjusts the input level of the device that’s
connected to the MIC IN jack or MIC/GUITAR IN jack.
When recording, use this knob to adjust the recording
level (p. 56).
* Setting [SENS] to the minimum position will not silence the
input completely. If you want to silence the microphone input
completely, set the Mic Input SW to the OFF setting (p. 59).
MIC IN jack
You can connect a microphone here (p. 55).
This is an analog audio input jack with a microphone preamp.
It can accept either balanced or unbalanced connections.
* The MIC/GUITAR IN jack and MIC IN jack cannot be used
simultaneously.
* The MIC IN jack can provide 48 V phantom power, allowing
a phantom-powered condenser microphone to be
connected.
Set the [SETTING] switch to the “MIC (DC 48 V 10 mA)” if a
phantom-powered condenser microphone is connected to
the MIC IN jack.

jacks. Wiring diagrams for these jacks are shown below.

LINE IN jack
You can connect a portable audio player or similar device
here (p. 58).
LINE OUT jacks
These jacks output the audio signal of the amp and mixer
in stereo (p. 56).
Ground terminal
If necessary, you can connect this to an external electrical
ground.

* 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 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 separate sheet titled “Information.”
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)
