USB-C™ compatible connection. Use this port to connect your StudioLive ARc-

1. Input-signal indicator. Each channel features an LED next to the trim control that
illuminates green whenever an input signal is present. The LED color will change to
red if the signal (pre- or post-EQ) reaches -3 dB.
2. Input Gain control. These knobs provide 43 dB of variable gain for mic
inputs and 40 dB of variable gain for line inputs (mono channels only).
3. Input Source button. Channels 1 and 2 offer an Input Source button
that lets you select instrument- or line-level for the ¼-inch inputs
on these channels. Press this button to engage the instrument
preamp when connecting guitars or a passive bass.
Note: Engaging the Instrument preamp will disable the
microphone preamp on the XLR connection.
4. Low Cut Filter (Mono channels only). When engaged, all frequencies
below 100 Hz will be attenuated (cut) at a slope of -18 dB/octave.
Power User Tip: Use the Low Cut filter to remove unwanted low-frequencies
from your source signal, rather than trying to EQ them out.
The stereo channels are equipped with a +10 dB Boost. When engaged,
this raising the level of both the mic and the line inputs by +10 dB.
5. High shelving EQ Gain control. Sets the level of the high-
band center frequency (10 kHz) from -15 to +15 dB.
Power User Tip: A high shelving EQ is like a treble-control knob on a stereo. In
this mode, the Center Frequency control selects the shelving frequency.
6. Mid peaking EQ frequency control (AR16c and AR12c, mono channels only).
Sets the center frequency of the Mid EQ. You can adjust the center frequency from
140 Hz to 3.5 kHz. This control is available on the Mono input channels only.
7. Mid peaking EQ gain control. Sets the level of the mid-band center frequency
from -15 to +15 dB. The center frequency can be adjusted on the mono inputs of
the AR16c and AR12c. All other inputs and the AR8c have fixed center frequency
at 2.5 kHz.
