Master Volume, Drive Amp122, Tone, “Halfmoon-Switch”
Master Volume:
If, for example, the overdrive control "Drive Amp122" is turned up, the overall level becomes
considerably louder. This can also lead to the override of the Vent II. In this case, the "Overload-Led" lights up.
This too high level must then be adjusted with the master volume control (turn to the left).
Drive Amp12
2: In addition to the accurate rotary simulation the X4 V also features a separate 122 amp output.
It emulates the sound and characteristics of the 12BH7 tube and the two 6550 tubes .The tube amp overdrive
starts from the center position of the volume control. Turning the volume control clockwise adds more
harmonic tube overdrive.
Note:
Drive Amp122 combined with the Drive of the Vent II brings finest and great overdrive results!
Tone:
Cranked up high frequencies accentuate the key click and percussion. Turn the knob counter-clockwise to
reduce high frequencies.
Note: It is recommended to discreetly dial back the high frequencies if the X4 V is played with
very high volume levels during live performance.
„Halfmoon-Switch“:
The "rotors" of the internal Rotary Vent II, as well as those of an external Rotary cabinet
connected to the 11pin socket, are controlled with the left hand (Slow, Stop, Fast) with this triple knob.
