Metering
5
Those units that feature VU meters allow you to gain an extra insight into
the signal being amplified. All Sebatron meters are driven by a discrete buffer
stage, so that no load is placed on the audio signal being monitored.
The meter level control gives you the choice of 3 possible ranges to allow
for a much greater dynamic range than the traditional VU. The medium range is
calibrated to 0dBu at the XLR balanced output.
Always remember that the VU specification was developed with tape in
mind, and as a result only represents a fraction of the dynamic range possible
with todays digital recordings. All Sebatron products are designed with this wide
dynamic range in mind and the limitations of the meter in no way represent the
limitations of the unit. Because we use no integrated circuits, there is no hard
clip point, only a gradual increase in valve warmth and then distortion that can
be musically useful. What this means is that if the meter is slamming against the
stops but the sound is just what you want, switch the meter to a lower level and
follow your ears. The input meters of your recording device show the only truly
important levels.
