Inputs
Red 4Pre has the capacity to accommodate eight analogue inputs, two independent 8-channel ADAT
inputs, a 2-channel S/PDIF input plus 32 Dante input channels.
(Additionally, when in Thunderbolt host
mode, an internal 2-channel loopback signal can be added as an extra stereo input – see page 13 for details)
analogue Inputs
The 8 analogue inputs can be assigned to the Instrument, Microphone or Line input connectors as
follows: Input channels 1 and 2 are selectable as instrument, microphone or line level; Inputs 3 and
4 are mic or line selectable; Inputs 5 – 8 are line level only.
Input Controls
Input selection and configuration for channels 1 to 4 is carried out
using the Preamp select buttons and the Input encoder.
The illuminated Select button identifies the channel being controlled.
• Pressing a Select button makes that channel the active channel
Power-up always selects channel 1
• The Input Encoder acts as the gain control for the active channel
• Pushing (’clicking’) the Input Encoder selects menu options or
operates the Toggle function
(see page 12)
Preamp Overview Screen
This is the default display for input channels 1 to 4. It shows at-
a-glance the current input type, gain setting and phantom power
status of the four inputs.
The highlighted number indicates the active channel
(as shown for
channel 1)
.
Note: a clipping channel will be indicated by its gain level bar changing to red (as
shown for channel 3) – reset by pressing the channel’s Select button.
Preamp Focus Screen
Pressing an input Select button brings up the Focus screen which
displays additional detail about that channel’s current settings.
If no changes are made within approximately 3 seconds, the display
will revert to the Overview screen.
In the example shown, channel 1 has the phase and HPF functions enabled.
