Preamp
An analogue preamplifier (‘head amp’) matches each
connected microphone or line signal to the operating
level of the console before it gets converted to digital
to be processed and mixed with the other channels.
Source lets you choose one of four sources as the
input to the channel. Press the Fn key to open the
Source screen.
Local = Mic/Line socket on the Qu rear panel.
dSNAKE = Remote preamp from AudioRacks.
Qu-Drv = Playback from USB hard drive.
USB B = Audio streaming from a Mac computer.
Touch the CH buttons to highlight those you
wish to change. Select the source from the list.
Input Patching – dSNAKE sockets can be
patched to any channel. A socket can be
patched to more than one channel.
Touch the Source page Patch button. This is a
shortcut to the I/O Patch / dSNAKE In page.
Touch a CH or ST button and turn the screen
rotary to select the dSNAKE socket number.
The button code indicates dSNAKE device:
N/C = No AudioRack is connected
Main = First AudioRack
Exp = Second (Expander) AudioRack
The reset default patch is one-to-one mapping of
dSNAKE to channel.
 The default patch for Qu-Pac and Qu-SB is
CH1-16 = Local1-16, and CH17-32 = dSNAKE 1-
16.
Input patching can be changed and is stored in
Scene memories.
