About Nutube
Nutube is a new vacuum tube developed by KORG INC and Noritake Itron
Corporation and that utilizes technology from vacuum fluorescent displays.
As with conventional vacuum tubes, the Nutube is constructed with an anode, grid
and filament, and operates as a complete triode tube. Furthermore, it generates the
response and the same rich harmonics characteristic of conventional vacuum tubes.

cabinet to any of the jacks.
When two speaker cabinets are connected simultaneously, it is parallel
connection. Minimum load is 4 ohms in total. When connecting the two
speaker cabinets of the same load, please use a speaker cabinet of 8 ohms
or more each.

This is BTL (Bridge-Tied-Load) output. This means both tip and sleeve is the
signal line, and sleeve is not grounded. Only use this jack for connecting
speakers to the amp. Connecting anything else may result in damages to
the amp.
The VOX MINI SUPERBEETLE has a built-in protection system that prevents
damage should unusual circumstances occur. If the sound cuts out for a few
seconds, don't worry, this is the amp protecting itself and your speakers.
If you find this happens, simply reduce the volume on the amp slightly.
(This protection only occurs with 16Ω speakers. 8Ω and 4Ω speakers are
unaffected.)
Speaker Cabinet Section
The cabinet has been specially voiced and designed to get the most out of your VOX
MINI SUPERBEETLE. Just plug into the cabinet and you'll hear what we mean!
Setup
1.
Set the amp head on the frame top of the
INPUT

8
3.
Connect the supplied AC adapter to the
power cord. Insert the DC plug end into
the DC 19 V jack. Next, plug the power cord
into an AC outlet.
Be sure you're using an AC power outlet of the correct voltage for your unit.
Use only the supplied AC adapter. Using any other AC adapter may cause
malfunctions.
4.
Plug the cable that's connected to your guitar into the INPUT jack.
5.
Plug the speaker cable that's connected to the speaker cabinet into SPEAKER
OUTPUT jack.
Please make sure the amp is turned off when you connect the speaker
cabinet.
6.
Turn the amp on, and slowly raise the VOLUME knob to adjust the volume.
Auto power-off function
The amp has an auto power-off function. With this function, the amp is automatically
turned off if there is no output for approximately 15 minutes. Switching the ECO
on enables the auto power-off function, whereas switching the ECO off disables
the function.
When the amp is turned off, it is not automatically turned back on. After the amp
is turned off, turn it on again or turn this switch off.
When the output level is extremely low or there is very little change in the
sound, the auto-power off function may be activated. In addition, depending
on the setting and environment, the amp may interpret noise as input, even if
the guitar is not being played.
