High: Boosts or cuts all frequencies above 10 kHz
by ±6 dB.
INPUT
Power User Tip: The High control on the Eris E44/E66
U
GAIN
is a high-shelf EQ and attenuates or boosts frequencies
above 10 kHz. This EQ is much like the treble control on a
car stereo: It raises or lowers the gain on all frequencies
above the specified cutoff frequency. Shelving EQs
can make big changes to the sound very quickly by
adding or removing an entire range of frequencies.
Mid: Boosts or cuts frequencies around 1 kHz by ±6 dB.
MIN
The Mid control is a peak EQ that lets you boost

or cut a specified frequency band (in this case, U

a band about two octaves wide, centered at 1

Low Cutoff: Rolls off the level of all frequencies below the
MAX
specified frequency (80 or 100 Hz) at a slope of -12 dB/
octave. Can be defeated by setting it to Flat, in which case,
the monitor's natural rolloff takes over.

the bass boost that occurs when the monitor is placed near
a wall or corner. Can be defeated by setting it to 0 dB.
