Microphone inputs. Your Studio 192 is equipped with eight digitally
controlled PreSonus XMAX microphone preamplifiers for use with all types of
microphones. The XMAX design provides 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 background noise.
The eight analog inputs of the Studio 192 feature combo jacks.
This convenient connector accepts either a ¼” phone plug or
an XLR plug. Mic Inputs 2-6 are located on the rear of the unit.
Instrument inputs. The ¼-inch TS connectors on Channels 1 and 2
are for use with instruments (guitar, bass, etc.). When an instrument
is plugged into the instrument input, the mic preamp is bypassed,
and the signal is routed to the instrument preamplifier stage.
Power User Tip: Active instruments are those that have an internal preamp
or a line-level output. Active instruments should be plugged into a line input
rather than into an instrument input. Plugging a line-level source into one of
the instrument inputs on the front of the Studio 192 not only risks damage to
these inputs but also results in a very loud and often distorted audio signal.
Please note: As with any audio input device, plugging in a microphone or an
instrument, or turning phantom power on or off, will create a momentary spike in
the audio output of your Studio 192. Because of this, we highly recommend that
you 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.
Preamp controls. These controls allow you to adjust the gain and enable
phantom power for every onboard microphone and instrument preamp.
• Preamp Gain: Use this control to adjust the level of microphone
preamps 1-8 and instrument preamps 1 and 2. The display
to the far right will show the current trim level.
• Next / Prev: Use these buttons to select the microphone preamp
you wish to control. The display to the right of the trim control
will show which preamp is currently being controlled.
• 48V: The Studio 192 provides 48V phantom power for each microphone preamp.
This feature can be individually enabled for each channel, using this button. When
48V is active, the blue LED at the top of that channel’s meters will illuminate.
WARNING: Phantom power is only required for condenser microphones and
can severely damage dynamic mics, especially ribbon mics. Therefore, switch
phantom power off for all channels where it is not required.
