Eris™ Series E5 and E8
Owner’s Manual
2.1.2 Power
IEC Power Connection: Your Eris E5/E8 accepts a standard IEC
power cord.
Warning: Do not remove the center grounding prong or use a
ground-lift adapter, as this could result in electric shock.
Power Switch. This is the On/Off switch. The power status is
indicated by an LED on the front of the cabinet.
AC Select Switch. The input-power voltage is set at the factory
to correspond with the country in which it was shipped. Use
this switch only if you are using your Eris speakers in a country
that uses a different standard voltage than is used in the
country where you purchased your Eris E5 or E8.
2.1.3 Acoustic Tuning Controls
High: Boosts or cuts all frequencies above 4.5 kHz
by ±6 dB.
Power User Tip: The High control on the Eris E5/E8 is a high-shelf
EQ and attenuates or boosts frequencies above 4.5 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.
The Mid control is a peak EQ that lets you boost
or cut a specified frequency band (in this case,
a band about two octaves wide, centered at 1
kHz). It’s capable of more subtle changes.
Low Cutoff: Rolls off the level of all frequencies below the
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.
Acoustic Space: Cuts the level of all frequencies below 800 Hz
by the specified amount (-2 or -4 dB) to compensate for the
bass boost that occurs when the monitor is placed near a wall
or corner. Can be defeated by setting it to 0 dB.
