FRONT PANEL CONTROLS

Input Gain control

This control optimizes the input signal level before the tube gain is applied. Both
Microphone and Instrument input gains remain the same and are affected by this
adjustment. Input gain can be adjusted from 0dB (for line level signals) to 45dB of gain.
The analog meters are used to see the effects of the input gain setting.
Additional gain is available via the Gain switch (+20dB) and the Analog Output control
(+10dB) for a maximum of 75dB total.
The combination of these controls allows the user to adjust the signal level through the
tube section, providing more or less "tube" sound as needed. To obtain more "tube'
sound, increase input gain, use the +20dB Gain switch, "normal" plate voltage, and less
Analog output gain.
