4.2 Preamps
The two preamps on the FIREstation are switchable. They can be
changed between solid-state and tube driven. The tube drive is
deactivated when the inner knob of the preamp is turned fully counter-
clockwise. This stage is indicated by a click when the knob is turned
fully counter-clockwise. The inner knob on each channel controls the
amount of signal routed to the 12AX7 vacuum tube. This feature lets
you control how much saturation of the signal occurs. Greater levels of
tube saturation give the signal greater warmth and a richer sound or
desirable distortion in extreme cases. This works equally well on mics
and instruments.
NOTE: Fully engaging the tube drive may increase the noise floor.
NOTE: It is recommended that the Control Room and Headphone
volumes be turned all the way down when the tube drive is initially
turned on.
4.3 Inputs
Each preamplifier has a Neutrik combo connector input. The input
accepts either XLR or 1/4” instrument inputs. The 1/4” or Hi-Z input is
designed for use with a guitar, bass, etc. This input is not a line level
input.
