2.1. Rear Panel Connections and Controls

Each Eris E3.5 pair consists of one active E3.5 and one
passive E3.5. Nearly every connection is located exclusively
on the active speaker. This speaker provides signal and
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.

2.1.1. Inputs (Active Speaker)

Eris™ Series E3.5

Owner’s Manual

Line-level Inputs. The Eris E3.5 active monitor provides a
choice of two pairs of inputs: left and right balanced ¼” TRS
and left and right unbalanced RCA. These inputs accept a
line-level signal from an audio source and feed that signal to
the each monitor’s built-in power amplifier. These inputs are
provided to enable flexible connectivity, not for connecting
multiple sources to your speakers simultaneously.

Power User Tip: The left inputs (balanced or unbalanced) send
signal to the amplifier that powers the active speaker; while the
right inputs send signal to the amplifier that powers the passive
speaker. Because of this, 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.
