Microphone Inputs. Your StudioLive is equipped with 32/24/16 PreSonus XMAX
microphone preamplifiers for use with all types of microphones. The XMAX
preamplifier 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 provides 48V phantom power for the
microphone input on each channel. This feature can be individually enabled for each
channel using buttons on the top panel.
WARNING: Phantom power is required for condenser microphones but can
severely damage some dynamic mics, especially ribbon mics. Therefore, switch
phantom power off for all channels where it is not required.
Power User Tip: Dynamic microphones and ribbon microphones are generally
lower-output devices and require no external power source. The most important
thing to note about ribbon microphones is that they very rarely require phantom
power. In fact, unless a ribbon microphone calls specifically for phantom power,
sending phantom power to it can cause severe damage. Condenser microphones
are generally more sensitive than dynamic and ribbon microphones and typically
require external +48V phantom power. Always review your microphone’s
documentation to ascertain the manufacturer’s recommended operating practices.
XLR connector wiring for phantom power:
Pin 1 = GND Pin 2 = +48V Pin 3 = +48V
