Selected Channel
The currently selected input channel is shown by the CH1 and CH2
indicators at the upper left of the main display panel, above the input
meters, as shown at right. The top panel controls adjust the functions
of the currently selected channel only.
Important: To adjust an input channel’s settings, that input channel
must be selected. The currently selected channel may need to be
changed to the other channel.
Changing Channels
When in preamp mode, press the PREAMP button to change the selected input channel
so its controls can be adjusted. Press PREAMP again to switch the selected channel
back to the other channel.
Tip: When in PREAMP mode, pressing the main LEVEL knob also changes the
selected channel.
Input Source
The Mic, Line, or Hi-Z inputs are routed into the input channel’s
preamplifier. The active input source is shown by the indicators
below the input meters, as shown at right.
The Mic or Line input source is selected by the pressing the INPUT button when the
channel is selected. The Hi-Z input (available on channel 1 only) is automatically
selected when an instrument cable is plugged into the Hi-Z input on the front panel.
Note: Only one input source at a time (Mic, Line, or Hi-Z) can be used as the
channel’s input source.
Preamp Gain
When an input channel is selected, its input gain is adjusted with the main LEVEL knob.
Preamp gain is applied to the Mic, Line, or Hi-Z input of the selected channel.
Preamp Options
Each input channel has six preamp options. The preamp options for the currently
selected input channel are enabled using the row of six buttons at the bottom of the top
panel when in PREAMP mode.
Preamp options display
The current state of the preamp options is displayed by the six options indicators (shown
above) at the bottom of main display. Available options are dim when inactive, bright
when enabled, and unlit when unavailable.
Note: Not all preamp options are available with all input types. For specific
details, see the Top Panel section later in this chapter.
