Microphone Inputs. Your StudioLive Series III mixer is supplied with 32/16 PreSonus
XMAX microphone preamplifiers, for use with all types of microphones. The XMAX
preamp features a Class A input buffer circuit, followed by a dual-servo gain stage.
This results in exceptionally low noise, and a wild range of gain, allowing you to boost
signals significantly without introducing unwanted background noise.
48-volt Phantom Power. The StudioLive provides individually-switchable 48V
phantom power for each microphone input.
WARNING: Phantom power is required for condenser microphones and certain other
specialty microphones that contain active preamp circuitry. However, applying phantom
power to mics that don't require power can damage them (especially ribbon mics). Switch
phantom power off for all channels where it is not required.
XLR connector wiring for phantom power:
Pin 1 = GND Pin 2 = +48V
Mic/Line Inputs. Half of the microphone inputs on your StudioLive can also accept
line-level signals. These inputs use TRS-XLR combo jacks that can accept both XLR
and balanced or unbalanced 1/4" cables. The ¼-inch TRS connectors bypass the gain
stage and are scaled to accept line-level signals up to +18 dBFS.
Power User Tip: When the line inputs are engaged, the microphone preamp circuit is
bypassed completely, and no trim control is available. Typical examples of line-level
connections are synthesizer outputs, signal processors, and stand-alone mic preamps
and channel strips. Use the output level control on your line-level device to adjust its level.
Note: As with many audio devices, plugging a microphone or line-level device, or
enabling/disabling phantom power can create a momentary noise spike in the audio
output of your StudioLive mixer. It is highly recommended that you mute or turn down a
channel's fader before changing connections or toggling phantom power on or off.
