Channels 3 Through 8 - Arturia AudioFuse 8 Pre User Manual

The INST button changes the impedance of the input channel to Hi-Z (high impedance). This
is designed to be used with instruments that have passive pickups, such as electric guitars
and basses, stringed instruments (mandolin, violin, etc.), and electric pianos (reed or tine-
based). So if you're connecting an instrument like one of those directly, activate the INST
button.

♪: If you're already using a pre-amp for your instrument, such as the output of an effects unit, you
probably don't need to use the INST button.
Phase
This button inverts the phase of the incoming signal. This is very useful in certain situations,
such as when you are using two microphones to record the output of a guitar amplifier.
For example, let's say you want to record the sound of a microphone that is close to the
speaker and another microphone that is placed further away to capture the sound of the
room. If there is a certain frequency that is being overemphasized by the distance between
the microphones (i.e., there's a harmonic node), try using the Phase button. The inversion of
the signal of one the microphones might cancel out the problem frequencies. (If not, move
the room mic to a slightly different location.)
Level meters
The function of these LEDs is fairly obvious: they let you know if the signal level is too low,
too high, or just right. One important detail is that CLIP will light up when the signal level
reaches -1 dBFS. This means you should lower the input gain. Set your levels so that the
peaks of the incoming signal are between the -10 and -6dB LEDs most of the time. This will
help to prevent unwanted distortion.

2.1.2. Channels 3 through 8

Everything that was described for
through 8, with the following exceptions:
• There are only two Input Source LEDs (Mic and Line).
• Channels 3-8 don't have an INST button.
• Connections for these channels are always made on the rear panel.
• Input channels 3-8 don't have insert jacks.
