Radikal Technologies SAC-2K: LCDs and Encoders

The following table outlines the LCDs and encoder controls, and their assignments:

Control
Assignment
Left and middle LCDs
Upper row displays the channel number when in a Mixer (multichannel) view mode. The parameter name is shown when in a (single) Channel view mode. Lower row shows the parameter value of the corresponding encoder (the one directly below the display). Level meters are shown to the right.
Right LCD
Upper row displays the name of the parameter being edited with the corresponding encoder (the one below). Lower row displays the parameter value (assigned to the encoder below the display). The Master Output level meter is displayed at the far right.
Encoders

Control
Modifier
Assignment
Pan
Switches to Mixer view (multichannel) pan editing.
High, HiMid, LowMid, Low
Switches to Mixer view (multichannel) gain editing of a certain EQ band. Encoders 9 to 12 edit Frequency, Gain, Q factor, and On/Off for the selected channel. Pressing and releasing the button chooses a specific EQ band. While held down, you can use Encoder 9 to choose the EQ band that you want to edit (bands 1 to 8). The button’s LED is lit when in Mixer view Gain Editing mode (of the selected channel EQ band).
  • Low: Band 3 (first parametric EQ band)

  • LowMid: Band 4 (second parametric EQ band)

  • HiMid: Band 5 (third parametric EQ band)

  • High: Band 6 (fourth parametric EQ band)

Snd/Ins
Switches the four Snd/Ins (1 to 4) buttons between Send and Insert modes.
  • LED off: Send mode

  • LED on: Insert mode

Snd/Ins 1 to 4
  • If in Send mode, switches to Mixer view (multichannel) send level editing of Sends 1 to 4. Encoders 9 to 12 edit Destination, Level, Pre/Post, and Mute of the selected channel. You must confirm the send destination by pushing the Encoder 9 button. While held down, use Encoder 9 to select the desired Send number (1 to 8). The button’s LED is lit when in Mixer view Send Level Editing mode (of the selected channel Send slot).

  • If in Insert mode, switches to Mixer view plug-in selection for Inserts 1 to 4. Plug-in selection is confirmed by pressing the encoder’s push button. While held down, use Encoder 9 to choose the desired Insert slot number (1 to 15). The button’s LED is lit when in Plug-in Selection mode (of the corresponding channel Insert slot).
