2.1.1 Inputs

Line-level Inputs. The Eris E44/E66 provides a choice of three

inputs: two balanced (XLR and ¼”TRS) and one unbalanced

(RCA). These inputs accept a line-level signal from your audio

source and feed that signal to the monitor’s built-in power

ampliﬁers. These inputs are provided to allow for ﬂexible

connectivity and not for connecting multiple sources to your

speakers simultaneously. Please connect only one source to

your Eris E44/E66.

Power User Tip: If your audio source provides balanced

XLR or ¼” TRS (tip-ring-sleeve) outputs, use one of the

corresponding balanced Eris inputs, since balanced cables

are resistant to induced noise from radio-frequency or

electromagnetic interference (RFI or EMI). If the audio source

has unbalanced ¼” TS (tip-sleeve) outputs, use a ¼”-to-RCA

adapter or adapter cable. Always use the shortest cable

possible to minimize the risk of induced RFI or EMI noise.

Input Gain: Sets the level of the input signal before it is

ampliﬁed.

2.1.2 Power

IEC Power Connection: Your Eris E44/E66 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

E44 or E66.

2.1.3 Acoustic Tuning Controls

High: Boosts or cuts all frequencies above 10 kHz

by ±6 dB.

Power User Tip: The High control on the Eris E44/E66

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.

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.

3.1 Monitor Placement

Ideally, near-ﬁeld monitors should be placed

so that the tweeters are at the same height

as your ears when you are mixing.

Eris E44 and E66 speakers can be placed vertically or

horizontally; when placed vertically, they should form a

mirror-image pair, with the tweeters on the outside.

When placed horizontally, the tweeters should be on top.
