Microphone Inputs. Your Studio-series interface is equipped with high-
quality microphone preamplifiers for use with all types of microphones. The
Studio 26c features XMAX-L solid-state microphone preamps that are
optimized for bus powering. The Studio 68c features XMAX microphone
preamps with a Class A input buffer, followed by a dual-servo gain stage.
Every input channel on your Studio-series interface is equipped with combo
jacks. This convenient connector accepts either a 1/4-inch or an XLR plug.
Instrument Inputs. The ¼-inch TS connectors on Channels 1 and 2 can be used with
passive instruments (guitar, bass, etc.). See
Input Source Button
for more information.
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 the instrument inputs not only risks
damage to these inputs but also results in a very loud and often distorted audio signal
Line-level Inputs. The ¼-inch, balanced TRS connection accept line-
level inputs. Typical examples of line-level connections are synthesizer
outputs, CD/DVD player outputs, and (with exceptions) signal-processor
outputs. The first two ¼-inch inputs can be switched between line-level
and instrument sources. See
Input Source Button
for more information.
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.
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.
Input Source Button. The first two input channels offer an Input Source button that
lets you select instrument or line level for the ¼-inch inputs. When the button is
illuminated, the input will accept a line-level source, such as a synthesizer or guitar
amp modeler. Press this button to engage the instrument preamp when connecting
guitars or a passive bass.
