Overview
• Microphone Inputs. Your StudioLive is equipped with 16 custom-designed PreSonus
XMAX microphone preampliers for use with all types of microphones (including dynamics,
condensers, and ribbons). The award winning PreSonus preamplier has a Class A input
buffer followed by a dual-servo gain stage. This arrangement results in ultra-low noise and
wide gain control, allowing you to boost signals without increasing unwanted background
noise.
• 48-Volt Phantom Power. The StudioLive has 48V phantom power available for each
channel individually via buttons on the top panel.
• XLR Connector Wiring for Phantom Power:
• Pin 1 = GND
• Pin 2 = +48V
• Pin 3 = +48V
• 22 dBu Headroom. The StudioLive microphone preamplier has +22 dBu headroom.
This gives you wide dynamic range and excellent transient-response characteristics.
• Line-Level Input. Each channel of the StudioLive has a 1/4-inch, balanced TRS connection
for line-level input. When these inputs are engaged, the microphone-preamp circuit is
bypassed.
Please Note: As with any mixer, plugging in a microphone or a line-level input device as well
as turning phantom power on or off will create a momentary spike in the audio output of your
StudioLive. Because of this, it is highly recommended that you mute or turn down the trim of any
channel before changing any connections or turning phantom power on or off. This simple step
will add years to life of your audio equipment.
• Insert. Each channel of the StudioLive has a direct-insert point. These unbalanced 1/4”
connectors can be used to connect external processors such as compressors, EQs, de-
essers, and lters with your StudioLive’s preamps and line 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. In other words, if you insert a de-esser on your vocalist’s channel, you will be
sending an unprocessed, amplied 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.
