(2) Gain Knobs
These knobs adjust the preamp gain for the microphones, instruments, or line level devices
attached to the associated inputs. For optimum gain, rotate the gain knob to adjust the input
signal level while monitoring the source that is connected, so the input meters (3) show signal
but do not light red.
(3) Input Meters
The Input Meters show the signal level of the input, which is controlled by the Gain knob. The
red input LED lights when the input signal is near 0 dB (clipping).
Tip: Clipping occurs when the signal is overloaded. When clipping occurs, the top of the
waveform is squared off, creating distortion that may be unpleasant. Clipping has creative uses,
but is usually avoided. To prevent clipping, adjust the gain so only green and yellow meters light,
and the red LED doesn't light.
(4) Vintage Buttons
Press these buttons to toggle the Vintage Preamps. The Vintage Preamps can be used on mic,
line, and instrument inputs.
