3.4 Acoustic Space Setting Suggestions
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 E4.5
provides an Acoustic Space switch that cuts all
frequencies below 1kHz 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.
