Necessary Steps - From Powering Up To Performance; About The Play Mode - Roland GR-30 Manual

<IMPORTANT: STEREO OUT and the Selection of Amplifiers>
To get satisfactory performance from the GR-30's
functions, and for the proper sounding of the preset
Patches that came with the GR-30 when you pur-
chased it, it is important to connect your setup to a
stereo amplifier or speakers (or headphones). Please
be sure to use stereo (two-channel) equipment.
If You Must Use a Monaural Amplifier...
• When you turn on the power switch while holding down
Pedal 1, "Mno" (Monaural) is displayed while the unit
starts up. This temporary monaural output status
remains in effect until the power is turned off.
• If you ordinarily use only a mono amplifier, please set the
pan for each patch to "0" (p. 39). Additionally, when
using the internal reverb as a delay, use "dL1" to "dL6"
(delay) instead of "Pd1" to "Pd6" (panning delay) (p.
42).
The GR-30's sound generator is a PCM synthesizer
which can reproduce a wide variety of tones. To better
reproduce these rich synthesizer sounds, it is better to
use a keyboard amp, other general instrument amplifier,
PA system, or other such equipment, instead of using a
guitar amplifier.
Necessary Steps — From Powering Up to Performance
After you have made all the connections properly (p. 12),
please be absolutely sure to carry out the following steps
when turning on the power. A mistake in the procedure
can result in faulty operation, or may even cause dam-
age to speakers or other components.
After you have finished checking connections, then,
with the sound completely turned down, that is, with
the GR-30's volume knob turned all the way counter-
clockwise, press the power switch on the rear panel,
to turn the unit on.
(Pressing the switch again turns the power off.)
If necessary, use the procedure shown on p. 81 to return
the GR-30's settings to their original values before
beginning.
In order to protect the instrument's circuits. After turn-
ing the power on there is a wait of several seconds before
operation can begin.
Ordinarily, the GUITAR OUT jack is used with a gen-
eral purpose shielded cable in connecting external
guitar effects or your own guitar amplifier. With this
arrangement, you can control the sound of the guitar
exactly in the same way as you would if the guitar
were not connected to the GR-30.
When there is no cable plugged into the GUITAR
OUT jack, the guitar sound is output from MIX
OUT, along with the synthesizer sound. This way,
both guitar and synthesizer sounds can be played
with just one amp. To add effects only to the gui-
tar sound, connect in the following way:
GR-30 GUITAR OUT Jack → External Effect Input
External Effect Output → GR-30 GUITAR RETURN Jack
With this arrangement, if you use a guitar effects
device (such as the Boss GT-5 or ME-8) simulating
a guitar amp, you can achieve the most suitable
sound quality for both the guitar and synthesizer
sounds.
The (L/R) MIX OUT jacks can also be used as dual
stereo headphone jacks. However, note that the
left and right output of the R (PHONES) jack are
reversed. Also be aware that you cannot simulta-
neously use one jack as a LINE OUT while using
the other as a headphone jack — that is, you can't
use a monaural plug and a stereo plug at the same
time.

About the Play Mode

After turning the GR-30 on, confirm that "A11"
appears in the three-digit display window. (This
number indicates the currently selected patch.
Patches are units representing the tones that can be
freely switched with a pedal, etc. during performance.
For details, see p. 29.)
