Apollo 8 Hardware Manual Front Panel 12
Channel Select
Pressing the Preamp knob changes the currently selected preamp channel, which deter-
mines which input (1 – 4) is adjusted by the front panel preamp controls. A preamp
channel is selected for adjustment when its Channel Select Indicator (#11) is
illuminated.
Each time the knob is pressed, the selected preamp channel increments to the next
preamp channel. If stereo linking is active, the stereo pairs are selected.
Gain Stage Mode
Gain Stage Mode is activated by pressing and holding the Preamp knob for two seconds
when a Unison plug-in is active in the channel’s dedicated Unison insert within the
Console application. When Gain Stage Mode is active, pressing and holding the knob for
two seconds deactivates Gain Stage Mode.
Gain Stage Mode is active when the Channel Select Indicator (#11) for the currently
selected channel is flashing. In this state, pressing the Gain knob cycles through the
available gain parameters within the Unison plug-in so each gain stage in the plug-in can
be adjusted from the front panel.
Note: For complete details about Gain Stage Mode, see the Unison chapter within
the Apollo Software Manual.
(3) Preamp Gain Level & State Indicator
Preamp Gain Level Indicator
The amount of preamp gain for the currently selected channel is indicated by the illumi-
nated ring surrounding the Preamp knob.
The ring indicates relative gain levels and is not calibrated to indicate any specific dB
value. However, precise numerical dB gain values for the preamps are displayed within
the Console application.
Note: If the ring is at maximum and flashes when the Preamp knob is rotated, the
channel’s LINE input is selected and LINE INPUT GAIN is set to BYPASS. See
Line Input Gain Bypass for additional details.
