  • Page 48: Producers Sofa Mic

    Producers Sofa Mic As an alternative, the 8424 return talkback can be used to create a second talkback feed from the control room into the live room. In this mode, the RTB signal is not sent to M2, (as is the case for the Live Room Return Talkback mode) but instead is sent to the CUE bus.
  • Page 49: Service Outputs (Dc Remotes)

    Service Outputs (DC Remotes) The 8424 console has a 15-Pin, 5 Channel D-Type connector on the rear of the console, Labelled as DC Remotes.

  • Page 50: Example Applications

    Group direct outputs, or bounced as individual stems back into the DAW by using the channel Direct Outputs. The 8424 has Marinair® Transformers on its Stereo Mix bus for true Voltage mixing. The processing on the master section of the console (Group/Stereo Mix EQ’s, Stereo width control, Channel, Group or master hardware inserts, 500 series inserts) allow for versatile tone shaping of Group signals and the main Stereo Mix signal.
  • Page 51: Recording

    Example Application – Recording When recording through the 8424 console, Input B allows individual line-level signals to be patched directly into the channel inputs via the ¼’’ balanced jack connections at the rear of the console. Any external Preamp line outputs can also be patched into the console via Input B, allowing multiple microphone sources to be recorded through the console surface.
  • Page 52: Overdubbing

    DAW return channels. Globally select Input A to return your previously recorded DAW tracks back through the 8424’s 24 channels. Overdubs can be recorded on any chosen channel 1 to 24 by selecting Input B as its channel input source. The selected channel will be setup to feed the channel Direct output into the DAW ready to record an overdub track.
  • Page 53: Input Mix Mode

    48 Mix Mode This mode of operation doubles the channel count of the 8424 console and enables 48 separate mono DAW inputs to be mixed simultaneously. This mode splits the console into two layers - The channel faders (I/P A) will input DAW interface outputs 1-24 and the ST CUE bus uses Input (I/P C) to input DAW interface outputs 25-48.
  • Page 54: In-Line Mode (Ilm)

    In-Line Mode (ILM) The 8424 is capable of functioning as an In-line studio console, with the ST CUE level control becoming the monitor return ‘Small Fader’. This allows for simultaneous mixing of both recording line inputs (I/P B) on the channel faders and monitor return inputs (I/P A) on the ST CUE controls.
  • Page 55: Parallel Processing

    Parallel Processing The 8424 has the capability of sending Input A (DAW interface Outputs 1-24) to two locations on the same channel strip. Both into the main channel input and into each channel CUE Input. This is the same function that enables In- Line Mode (ILM).
  • Page 56: Audio Interface Setup

    32 I/O Audio AD/DA Interface A 32 in 32 out AD/DA audio interface allows for full functionality of the 8424 console. with this setup, 24 DAW returns can be patched into all channel inputs via Input A, and a further 8 can be patched into Input C. This enables simultaneous summing of up to 32 individual audio channels through the console using 48 MIX mode.
