Main Features

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.

This amp has 2 channels, and each channel has 2 modes.

Channels can be selected with the CHANNEL switch.

Please set this switch to FSW position, to enable the optional foot switch.

2-1. CH1

CH1 has 2 modes, CLEAN and CRUNCH.

This channel has GAIN, TONE and VOLUME controls.

In addition, you can tweak your tone with the versatility of the BRIGHT and FAT switches.

2-2. CH2

This channel has GAIN, TREBLE, MIDDLE, BASS and VOLUME controls.

In addition, you can tweak your tone with the versatility of the BRIGHT, FAT and MID-SHIFT switches.

3. REVERB

This amp has a high quality digital reverb inside.

This can be switched On or Off by the foot switch.

4. PRESENCE, RESONANCE

These controls allow more detailed voicing of your tone.

PRESENCE controls the high-end frequency, whereas RESONANCE controls the low-end frequency.

5. MASTER1, 2

This amp has 2 MASTER volume controls, that can be switched by the foot switch.

Please use MASTER1 as a normal MASTER volume.

MASTER2 can be selected only when you connect a foot switch.

Setting this higher will push the Nutube in the power amp, into greater saturation.

1. Nutube BIAS

You can control the bias voltage of Nutube for CH1 and CH2 individually.

VINTAGE: Decreasing the voltage makes the amp sound like a vintage guitar amp, this sometimes makes your tone feel a little more unstable (like the old days).

MODERN: Increasing the voltage creates more gain, and makes its tone smoother.

2. EFFECT LOOP

This has SEND and RETURN jacks, and a SERIES/PARALLEL switch.

This can be switched On or Off by the foot switch.

3. FOOTSWITCH

There are 2 foot switch jacks to switch the setting of the amplifier as below.

Optional VFS2 or VFS2A is accepted.

TIP! You can also use a commercially-available open/close type footswitch with a TRS standard phone jack connection.

TIP: LOOP ON/OFFRING: REVERB ON/OFF	Switch 1 Switches the EFFECT LOOP on/off.
	Switch 2 Switches the REVERB on/off.
TIP: CHANNEL 1/2RING: MASTER 1/2	Switch 1 Switches between CHANNEL 1 and CHANNEL 2.
	Switch 2 Switches between MASTER1 and MASTER2.

4. EMULATED LINE OUT

This output has a built-in analog speaker cabinet emulation circuit. This sounds like you're using a well-known dynamic microphone in front of your speaker cabinet.

5. SPEAKER OUTPUTS

MVX150C1 has 1 EXTERNAL speaker jack. Use this jack to use another speaker cabinet. Connecting to this jack disables the internal speaker. Minimum load is 4ohms.

MVX150H has 2 parallel speaker jacks.

With the MVX150H, you can connect two speakers at the same time, for a parallel connection. When doing so, make sure that the combined impedance is not less than 4 ohms. When connecting two of the same speakers, use speaker cabinets of 8 ohms or more on each.

5-1. POWER LEVEL

This 6 way selector decides the total output volume. MUTE position disables the power amp, so that you can do a silent recording with the EMULATED LINE OUT.

5-2. IMPEDANCE

Please select the same value as the impedance of the speaker cabinet you use.

(MVX150C1 internal speaker is 4ohm)

5-3. WET ONLY SPEAKER OUTPUT

You can get only the WET signal from this speaker output, when using EFFECT LOOP or REVERB. Connecting to this jack makes the standard speaker output DRY automatically, so that you can achieve the professional DRY/WET setup very easily.

This output is independent from the standard speaker output. Minimum load is 4ohms.

If you use the WET ONLY OUTPUT, the total output wattage will be switched automatically.

For example, when you plug the speaker cabinet into both DRY and the WET ONLY OUTPUT, the maximum output wattage will be limited to 75W for DRY, and 75W for WET.

NOTE! Speaker jack does not need to be used if not required. This won't harm the amp.

NOTE! 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 MVX150. Connecting anything else may result in damages to MVX150.

WARNING! To ensure that your system works correctly, you must observe the following points.

a) Don't connect a speaker whose rated input capacity is less than the total output wattages. The speaker may be destroyed if you ignore this caution—not recommended!

b) You must use a speaker cable to connect an external speaker. Don't use a shielded cable like the one you use to connect a guitar to an amp.

c) You must turn off the power before connecting the speaker cable. Connecting the cable while the power is turned on may damage your amp.

NOTE! It is recommended that all audio cables (with the exception of the speaker lead), used to connect to the MVX150C1/MVX150H are of a high quality, screened type. These should not exceed 10 metres in length.

6. ECO switch

This switch decides the setting of ECO mode and LED mode.

ECO=ON enables the auto power-off function.

LED=ON turns the LED illumination on.

7. Power switch

Hold this switch, to turn the amp ON, or STANDBY (OFF).

8. MAINS INPUT

Connect the included power cord here.

WARNING! Be sure to plug the power cord into an outlet of the appropriate voltage.

WARNING! Use only the included power cord. Using any different power cord may cause malfunctions or other issues.

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 30 minutes.

When the amp is turned off, it is not turned back on, even if a control is operated. After the amp is turned off, turn it on again.

NOTE! When the input 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 settings and environment, the amp may interpret noise as input, even if the guitar is not being played.

TIP! As the factory default setting, the auto power-off function is enabled (ECO SW=ECO: ON). The function can be disabled by moving the ECO switch to the ECO: OFF position.

Over load protection function

This amp has an over load protection function for its safety.

The power amp will be disabled, if the speaker output was shorted, or had some trouble with an impedance of the speaker cabinet you connect. Moreover, the amp will be shut down when the total output wattage exceeds 150W. With these cases, please check the connection or the impedance of the speaker cabinet you connect, and re-start the amp.
