Rear-Panel Connections

Line-level Inputs. Each channel of the StudioLive has a ¼-inch, balanced TRS
connection for line-level input. When these inputs are engaged, the microphone-
preamp circuit is bypassed. Typical examples of line-level connections are synthesizer
outputs, CD/DVD-player outputs, and (with exceptions) signal-processor inputs and
outputs.
output of your StudioLive. Because of this, it is highly recommended that you mute or turn
down the channel trim before changing connections or turning phantom power on or off.
This simple step will add years to life of your audio equipment.
Insert. Each input channel on the StudioLive has a direct-insert point. These
unbalanced, ¼-inch connectors can be used to connect external processors (such as
compressors, EQs, de-essers, and filters) to your StudioLive's channel inputs. The
insert's send is after the channel's gain control but before the digital bus. The return
goes straight to the digital bus. So if you insert a de-esser on your vocalist's channel,
you will be sending an unprocessed, amplified signal to the de-esser; the processed
signal returned to the StudioLive will then be routed to the digital bus, where it can
be sent through the Fat Channel, Aux and FX buses, etc.

Aux Inputs. The StudioLive offers two auxiliary inputs. While these line inputs
are generally used as effects returns, they can also be used for any line-level
source (synthesizers, amp modelers, etc.). In Section 4.4.7, we discuss using
an aux bus to send several channels to an external effects processor; the aux
inputs can be used to return the processed signal to the mixer. Each input is
balanced stereo. The left input is normalled to the right input, so if you are
returning a mono signal to the mix, connect it to the left input, and the signal
will be routed to both sides of the mix.
Subgroup Outputs. These are balanced mono outputs for each subgroup.
