UNIT SELECTION
Now that you have finished making the con-
nections, you are ready to use the US-20 to
select units to be played.
1. Set the Select switch on the GK-2A to [SYNTH].
2. Rotate [SYNTH VOL] on the GK-2A fully
clockwise.
3. Play the guitar.
Unit Selection with
the [A/B] Pedal Switch
Depress the [A/B] pedal, and the unit to be
played will change. You can tell whether UNIT
A or B is currently selected by viewing the LED.
Red
:
The unit connected to UNIT A is selected.
Green
: The unit connected to UNIT B is selected.
Information about the setting for [SYNTH
VOL] on the GK-2A and whether [DOWN/S1]
or [UP/S2] has been pressed or not will be
sent only to the currently selected unit.
Unit Selection with
the [BOTH] Pedal Switch
Depress the [BOTH] pedal, and the LED will
light in yellow and both units connected to
UNIT A and B will be heard. However, infor-
mation about whether [DOWN/S1] and
[UP/S2] have been pressed or not will be sent
only to the device selected with the [A/B]
pedal switch.
Depress the pedal again, and the LED will go
out and only the device selected with the
[A/B] pedal switch will be heard.
* If you set the Select switch on the GK-2A to [MIX]
or [GUITAR], the direct sound from the guitar can
be heard. This guitar sound cannot be controlled
with [SYNTH VOL] on the GK-2A or the [A/B]
pedal switch on the US-20.
That is, if you set the Select switch on the GK-
2A to [MIX] or [GUITAR], the guitar sound
will be output through the Guitar Out jack on
the device connected to UNIT A and B, even if
the [A/B] pedal has been used to select UNIT
A or B.
* When use with the Roland GR series, please set the
GK-2A
Synth Volume Function
to “synth vol-
ume."
* When use with the Roland VG series, please set the
GK-2A Synth Volume Function to “master vol-
ume" or “pickup level."
