USB Signal Routing and Block Diagram

BiG SiX retains all the SuperAnalogue signal quality attributes of its smaller sister SiX console, however with a larger footprint BiG
SiX also incorporates 16 high quality Analogue to Digital and Digital To Analogue converters and a class compliant USB interface.
This interface is capable of interfacing all 16 digital channels of digital audio to and from a connected workstation at sample
frequencies of 44.1, 48, 88.2 and 96 kHz with 24 bit resolution.
The block diagram opposite shows how the A to D and D to A circuits are connected within BiG SiX.

USB Returns 1 - 16 (Signal flow from the DAW to BiG SiX)

USB returns 1 to 4 from the workstation are connected to a switched input to the four Mono SuperAnalogue channels. They are
connected after the pre-amp and therefore are at unity gain (0 dB) into the mono channel signal path.
USB returns 5 to 12 are connected to a switched input to the four stereo channels. They are connected prior to the line amplifier
and therefore are at unity (0 dB) in the centre detent position of the Trim control with +20 to -10 dB of gain available.
USB returns 13/14 and 15/16 are connected to the External Inputs by way of a pair of switches
located next to the TALK LEVEL control. These switches override the TRS External Input
connections at the top of the front panel. There are also small USB labels next to the EXT 1 and
EXT 2 switches to act as reminders.

USB Sends 1 - 16 (Signal flow to the DAW from BiG SiX)

USB sends 1 to 4 to the workstation are connected to the pre-fader output of the four Mono SuperAnalogue channels. This feed
can be switched Post Fader by selecting the individual USB OUT POST FADER switches next to each of the 100 mm faders for the
channel. This is useful if you want to record the channel signal including its level back to the DAW. Typically this is used where a
summing mix of stems is recorded back to the workstation, so that to re-create the mix at a later date, the stems are simply returned
to the console with the channel at unity gain, re-creating the original summing mix for re-mixing/re-balancing.
USB sends 5 to 12 are similarly** connected to the pre-fader output of the four stereo channels. Again, this feed can be switched
Post Fader by selecting the individual USB OUT POST FADER switches next to each of the 100 mm faders for the channel. These
Post Fader feeds are also post the Balance control to make it easy to return a stereo stem mix at unity gain for later re-mixing.
** USB Sends 9/10 and 11/12 can be re-directed to be fed from Stereo Cue 1 and Stereo Cue 2
respectively using a pair of switches at the top of the Stereo Cue Master section. If either switch
is pressed, the green LED will light. This feature is useful if you want to use the Stereo Cue Sends
to feed effects processing created in the workstation. The effects return would typically be fed to the External Inputs and summed
to the Main Bus using the EXT 1 and/or EXT 2 switches above the Main Fader.
USB Sends 13/14 are connected to the output of Bus B, after the Bus B MUTE and stereo Level Control.
USB Sends 15/16 are connected to the output of the Main Bus after the Main Fader, providing a simple way to print a mix back to
the workstation.
