Thank you for purchasing the VOX “MV50 series” guitar amplifier.
To help you get the most out of your new instrument, please read this
manual carefully.
About Nutube
Nutube is a new vacuum tube developed by KORG INC and Noritake
Itron Corporation and 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 as well as the same rich harmonics
characteristic of conventional vacuum tubes.

. SPEAKER OUTPUT jack:
Connect the speaker cable to this jack. The
minimum speaker’s impedance is 4ohms, and you will get approx.
50W output with 4ohms, 25W with 8ohms, and 12.5W with 16ohms
load.
Do not connect a load less than 4ohms.
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 MV50. Connecting anything
else may result in damages to MV50.
Setup
1. Turn the VOLUME knob on the amp to the minimum position.
2. 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.
Use only the supplied AC adapter. Using any other AC adapter
may cause malfunctions.
3. Plug the cable that’s connected to your guitar into the INPUT jack.
4. Plug the speaker cable that’s connected to the speaker cabinet into
SPEAKER OUTPUT jack.
SPEAKER OUTPUT jack may not be used if not needed. This
won’t harm the amp.
5. 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.
