EQ curve. On the other hand, if you want to emulate a
cheap portable radio, try turning it up above 0. Try not
to boost much, since this can add noise to the signal.
The Low Cutoff control rolls off the low frequencies below
the specified frequency (80 or 100 Hz). Engage this control if
you are using a subwoofer in conjunction with the Eris E5/E8
monitors, and set it to the same frequency as the crossover
to the subwoofer. If you’re not using a subwoofer, set the
control to Flat. If you want to emulate a cheap radio, engage
this control at 80 or 100 Hz while boosting the Mid control.
Power User Tip: Do not use the EQ controls on
your Eris monitor to correct problems in your mix.
While this changes what you hear in the control
room, it has no effect on your recorded audio.
3.4 Acoustic Space Setting Suggestions
When a monitor is placed close to a wall, or in a corner,
the low frequencies tend to be emphasized more than
if the monitor is far from any room boundary; this effect
is called “boundary bass boost.” It is most pronounced
if the monitor is in a corner and less pronounced,
but present, if the monitor is near one wall.
To compensate for this bass boost, the Eris E5/
E8 provides an Acoustic Space switch that cuts all
frequencies below 800 Hz by a fixed amount.
If the monitors are close to the corners of the room, start by
setting the Acoustic Space switch to -4 dB, which provides
the most bass attenuation.
If the monitors are close to the back wall, try setting the
Acoustic Space switch to -2 dB for less attenuation.
If the monitors are far from any wall, there will
be no bass boost, so set the switch to 0 dB.
