Overview:

When you’re ready to get serious about recording, it’s time to step up to PreSonus Eris-series studio monitors. Cheap computer speakers and home-stereo speakers won’t reveal the truth about your mix. They aren’t designed for that.

  • 50 watt, Class AB amplification (25W/side)
  • Acoustic Tuning control for accurate mixing contour: Midrange (+/-6 dB, continuously variable), HF (+/-6 dB, continuously variable), High-Pass (Off, 80 Hz, 100 Hz), Acoustic Space settings (flat, -2, -4 dB)
  • RF interference, output current limiting, over-temperature, transient, and subsonic protection

  •  Balanced 1/4-inch TRS, unbalanced 1/8-inch TS, RCA, and bare-wire inputs
  • 1/8-inch stereo headphone output and bare-wire power-amplifier output
  • 100 dB maximum continuous SPL
  • 70 Hz
  • 20 kHz frequency response
Front Panel Features:

  • Power Switch - This is the ON/OFF switch. The LED above the volume control indicates power status
  • 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.
  • AUX in - This stereo 1/8" jack can be used to patch in an MP3 player for a quick reference check.
  • Headphone Out - This headphone output is controlled by the level knob

Rear Panel Features:

  • INPUTS: The Eris E4.5 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.
  • IEC Power Connection. The Eris E4.5 accepts a standard IEC C7 power cord. The power switch is  located on the front panel of the active E4.5.

  • AC Select Switch. The input-power voltage is set at the factory to correspond with the country to which it was shipped. Change the setting on 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 E4.5

  • Acoustic Tuning Controls

    High-  Boosts or cuts all frequencies above 10 kHz by ±6 dB.

    Mid - Boosts of cuts frequencies around 1 kHz by ±6 dB

    Low Cutoff - Rolls off the level of all frequencies below the specified frequency (80 or 100 Hz) at a slope of -12 dB/octave. This can be defeated by setting it to Flat, in which case, the monitor’s natural roll-off takes over.

    Acoustic Space- Cuts the level of all frequencies below 1 kHz 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. This can be defeated by setting it to 0 dB.

  • Speaker Connections : Bare-wire connectors. This connection is used to power and send signal to the passive E4.5. Be sure to connect the positive and negative connections on your active E4.5 to the positive and negative connections, respectively, on the passive E4.5 (i.e., connect positive to positive and negative to negative).
