Connecting the AC adaptor
Use only the AC adaptor included with the CUBE STREET. 
Use of other AC adaptors may damage the amp or result in 
other problems.
To prevent the inadvertent 
disruption of power to your 
unit (should the plug be 
pulled out accidentally), and 
to avoid applying undue 
stress to the AC adaptor jack, 
anchor the power cord using 
the cord hook, as shown in 
the illustration.
Place the AC adaptor so the side with the indicator (see 
illustration) faces upwards and the side with textual 
information faces downwards. The indicator will light when 
you plug the AC adaptor into an AC outlet.
A Note About Batteries
In addition to the AC adaptor, the CUBE STREET can also be 
powered with six AA batteries (optional). Insert the batteries 
as shown in the figure, making sure that the batteries are 
oriented correctly.
If there are batteries in the unit while an AC adaptor is being 
used, normal operation will continue should the line voltage 
be interrupted (power blackout or power cord disconnection).
* When installing or replacing batteries, always turn off the 
power on this unit and disconnect any other devices you may 
have connected. This way, you can prevent malfunction and/or 
damage to speakers or other devices.
* Expected battery life under continuous use:
Alkaline: approx. 15 hours
This figure will vary depending on the actual conditions of use.
TUNING
You can use “manual tuning,” whereby you switch to each 
individual string to tune it separately, and “chromatic 
tuning,” which automatically determines the closest pitch to 
that played by the string.
Tuning in “Manual Mode”
1. Press the TUNER switch.
2. Use the Type switch to select the name of the string you 
want to tune, then play a single note on the open string.
* The sound of the guitar/instrument channel will not be heard 
from the unit's speakers while you're using the tuner function.
* Reference Pitch: A4=440 Hz
3. Tune the string until the green indicator lights.
              <The Pitch is flat>                <The Pitch is flat, but almost in tune>
* When the pitch is even lower, the indicator flashes.
         <The Pitch is correct>
<The Pitch is sharp, but almost in tune>         <The Pitch is sharp>
*
When the pitch is even 
higher, the indicator flashes.
Tuning in “Chromatic Mode”
1. Hold down the TUNER switch for at least one second 
so that the red indicator flashes.
2. Play a single note on the open string you want to tune.
3. Tune the string until the green indicator lights.
