Using the Tube Amp switch
Engaging the Tube Amp switch tends to have a significant impact
on the overall sound, as it directly changes the sonic character
of the tube. The higher the Tube Amp value, the more you will
have tube saturation and harmonic distortion, in addition to
limiting effects. These effects can be used creatively to shape a
sound.
Subtle overdrive of the tube creates moderate saturation effects
and relatively little harmonic distortion—the limiting effects are
already present. If this behavior is desired, try a +12 dB setting
with the Gain control also set to moderate pre-amplification.
For a more dramatic tube sound the Tube Amp switch should
be set to +18 dB. This results in a very audible saturation and
harmonic distortion. The intensity can then be fine-tuned with
the Gain control: The more gain, the more phatt ...
Tube limiting controls peaks in a musically advantageous
fashion and can be used to complement the Limiter. The tube
limiting is not as accurate and sonically neutral as the Peak-
Limiter because harmonic tube distortion is added to the
signal.
To fully protect connected converters you should keep the Peak-
Limiter active and monitor the action of the VU meter, the Clip-
and Limiter-LED.
