Connections and Controls
Each Eris media reference monitor pair consists of one active speaker and one passive speaker. Nearly every connection is located exclusively on the active speaker. This speaker provides essignaland power for the passive speaker. The exceptions are the bare-wire connectors, which send power and signal from the active speaker to the passive speaker.
Rear Panel
Inputs
Line-level Inputs. The Eris active speaker provides a choice of two pairs of inputs on the rear panel: left and right balanced ¼” TRS and left and right unbalanced RCA. These inputs acceptable-level signals from an audio source and feed that signal to each monitor’s power amplifier. These inputs are provided to enable flexible connectivity, not for connecting multiple sources to your speakers simultaneously. A third 1/8” stereo input is available on the front panel, please see Section 2.2 for more information.
PowerUser Tip: The left inputs (balanced or unbalanced) send a signal to
the amplifier that powers the active speaker; and the right inputs send a
signal to the amplifier that powers the passive speaker.PreSonus recommends
that the active speaker be placed on the left side of your mixing space and
the passive speaker be placed on the right.
However, if you prefer to have the controls located on your active monitor
placed on the right side of your workspace, be sure to reverse the inputs from
your audio source to maintain the correct stereo image.
Connections and Controls
Power
IEC Power Connection. The Eris active speaker accepts a standard IEC C7 power cord. The power switch is located on the front panel of the active speaker.
Acoustic TuningControls
High. Boosts or cuts all frequencies above 10 kHz by ±6 dB.
PowerUser Tip: The High control is a high-shelf EQ and attenuates or
boosts frequencies above 10 kHz. This EQ is much like the treble control on a
home or 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.
Power User Tip: The Low control is a low-shelf EQ and attenuates or
boosts frequencies below 100 Hz. This function is the equivalent to the Bass
control on a home or car stereo:
It raises or lowers the gain on all frequencies below the specified cutoff
frequency.
Shelving EQs can make big changes to sound very quickly by adding or removing
an entire range of frequencies.
Speaker Connections
Bare-wire connectors. This connection is used to send power and send signals to the passive Eris speaker. Be sure to connect the positive and negative connections on your active Eris speaker to the positive and negative connections, respectively, on the passive Eris speaker (i.e. connect positive to positive and negative to negative).
Active Speaker Front Panel
Power Switch. This is the On/Off switch.
Power/Bluetooth Status LED. The LED above the volume control indicates the power status for all Eris speaker models. For Eris E3. 5BT and E4. 5BTreference monitors, this LED also displays the Bluetooth status as follows:
- Solid Blue. Eris speaker is powered on.
- Flashing Blue (Eris E3.5 BT and E4.5 BT only). Eris speaker is in pairing mode.
- Solid White (Eris E3.5 BT and E4.5 BT only). Eris speaker is paired to a Bluetooth device.
Volume. Sets the volume level of the input signal before it is amplified. This is also the volume control for the front-panel headphone amp.
AuxIn. Thisstereo1/8” jack can be used to patch the media players for a
quick reference check.
Headphone Out. This headphone output is controlled by the Level knob.
PowerUser Tip: When the headphone output is connected, audio will be muted to your Eris speakers. So, you can listen as loud as you like without disturbing the neighbors.
