Eris™ Series E4.5 Owner’s Manual
3.2 Level Setting
Make sure that the gain controls on your audio source have
been optimized for maximum signal level and minimum
noise. This process is called “gain staging,” and you can learn
about it from many online sources. You should always set
the volume on your Eris monitor so that all other level
controls in the system needn’t be turned way up or way
down to achieve a comfortable listening volume.
If you properly gain-stage your audio source, setting the
Eris Volume to 12 o’clock or slightly lower should work fine.
Once the monitor’s volume control is set, leave it
alone; don’t use it as a system-volume control. Leave
that job to your audio device’s output-level control.
3.3 Equalizer Setting Suggestions
The Eris 4.5 provides three EQ controls in its Acoustic Tuning
section: High, Mid, and Low Cutoff. (There’s also an Acoustic
Space control, which is covered in the next section.) In
general, setting the High control to 0 (no boost or cut) will
produce the best results. However, if the sound is generally
too bright or shrill, try turning this control down below 0; if
the sound is too dull and lifeless, try turning it up above 0.
It’s always better to cut than to boost and to use the
smallest cut or boost needed to get the job done.
The Mid control is a mid-frequency peak filter that boosts
or cuts frequencies centered on 1 kHz and extending
about one octave above and below that frequency. Again,
setting this control to 0 will generally produce the best
results. If you want to emulate a car stereo, try turning it
down below 0 to approximate the common “smiley face”
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 E4.5
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.
