3.2
Channel Controls
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 50 dB of variable gain for mono
channels (0 to +50 dB mic/instrument, -20 to +30 dB line) and 40 dB of variable
gain for stereo channels (+5 to +45 dB mic/instrument, -15 to +25 dB line).
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.
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.
5.
High shelving EQ Gain control.
Sets the level of the high-
band center frequency (12 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 (AR16 USB and AR12 USB).
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 AR16 USB and AR12 USB.
All other inputs have fixed center frequency at 2.5 kHz.
8.
Low shelving EQ gain control.
Sets the level of the low-
band center frequency (80 Hz) from -15 to +15 dB.
Power User Tip:
A low shelving EQ is like a bass-control knob on a stereo. In
this mode, the Center Frequency control selects the shelving frequency.
