1. Introduction
This manual provides comprehensive instructions for the PreSonus Eris E5 2-Way 5.25-inch Near Field Studio Monitor. The Eris E5 is designed to deliver accurate audio reproduction for studio monitoring applications. This document covers essential information regarding setup, operation, maintenance, troubleshooting, and technical specifications to ensure optimal performance and longevity of your monitor.
2. Important Safety Instructions
Before operating your Eris E5 monitor, please read and understand the following safety instructions:
- Power Source: Connect the unit to a power supply of the type specified in the operating instructions or marked on the appliance.
- Grounding: Ensure the power cord is connected to a grounded outlet. Do not defeat the safety purpose of the polarized or grounding-type plug.
- Ventilation: Do not block any ventilation openings. Install in accordance with the manufacturer's instructions.
- Heat: Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat.
- Water and Moisture: Do not use this apparatus near water or expose it to rain or moisture.
- Cleaning: Clean only with a dry cloth.
- Servicing: Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.
- RF Shielding: The Eris E5 includes RF shielding.
- Protection: Features current-output limiting, over-temperature protection, and subsonic protection.
3. Package Contents
Your PreSonus Eris E5 package should contain the following items:
- One (1) Eris E5 Studio Monitor
- One (1) Power Cable
- Four (4) Foam Feet (for isolation)
- One (1) Product Manual (this document)
4. Setup
4.1. Placement
Proper placement of your Eris E5 monitors is crucial for accurate sound reproduction. Consider the following guidelines:
- Listening Position: Position the monitors so that the tweeters are at ear level when you are in your primary listening position.
- Equilateral Triangle: Form an equilateral triangle between the two monitors and your listening position. The distance between the monitors should be equal to the distance from each monitor to your ears.
- Distance from Walls: While the Eris E5 features a front-firing acoustic port, placing monitors too close to walls or corners can exaggerate bass frequencies. Use the Acoustic Space controls on the rear panel to compensate for boundary effects.

4.2. Connections
The Eris E5 offers flexible input options. Ensure all connections are secure before powering on the unit.
- Balanced Inputs: Use XLR or 1/4-inch TRS cables for balanced connections from your audio interface or mixer. Balanced connections help reduce noise over long cable runs.
- Unbalanced Input: An RCA input is provided for connecting consumer audio devices.
- Power: Connect the included power cable to the IEC power inlet on the rear panel and then to a grounded AC outlet.

4.3. Acoustic Tuning
The Eris E5 features acoustic tuning controls on the rear panel to optimize its response for your specific listening environment.
- Acoustic Space: This switch compensates for bass boost that can occur when monitors are placed near walls or in corners. Options are 0 dB (flat), -2 dB, and -4 dB. Start with 0 dB and adjust if bass sounds overly prominent.
- Low Cutoff: This filter removes frequencies below a selected point (Flat, 80 Hz, or 100 Hz). Useful when using a subwoofer or to reduce rumble.
- Mid EQ: Adjusts the mid-range frequencies.
- High EQ: Adjusts the high frequencies.
- Input Gain: Controls the input sensitivity of the monitor. Adjust this to match the output level of your audio source.
5. Operating Instructions
5.1. Power On/Off Sequence
To prevent loud pops or damage to your speakers, follow this power sequence:
- Power On: Turn on your audio source (computer, interface, mixer) first, then turn on the Eris E5 monitors.
- Power Off: Turn off the Eris E5 monitors first, then turn off your audio source.
5.2. Volume Adjustment
Adjust the overall listening volume using the input gain knob on the rear of each Eris E5 monitor. For fine adjustments, use the volume control on your audio source (e.g., audio interface, mixer, computer). It is generally recommended to set the monitor's input gain to a moderate level and control the primary listening volume from your audio source.
6. Maintenance
To ensure the longevity and optimal performance of your PreSonus Eris E5 monitors, follow these maintenance guidelines:
- Cleaning: Use a soft, dry, lint-free cloth to clean the exterior of the monitors. Do not use abrasive cleaners, waxes, or solvents, as these can damage the finish and components.
- Dust: Regularly dust the speaker cones and grilles to prevent accumulation that could affect sound quality.
- Ventilation: Ensure that the ventilation openings on the rear of the monitors are not obstructed.
- Environment: Avoid exposing the monitors to extreme temperatures, humidity, or direct sunlight.
7. Troubleshooting
If you encounter issues with your Eris E5 monitors, consult the following common problems and solutions. For more detailed troubleshooting, refer to the official Troubleshooting Guide (PDF).
- No Sound:
- Check all cable connections (audio and power).
- Ensure the monitors are powered on and the power indicator light is illuminated.
- Verify the volume/gain controls on both the monitors and your audio source are not set to minimum.
- Confirm your audio source is sending a signal.
- Hissing or Humming Noise:
- Ensure you are using balanced cables (XLR or TRS) for longer runs, as unbalanced RCA cables are more susceptible to interference.
- Check for ground loops. Try connecting all audio equipment to the same power outlet or using a ground loop isolator.
- Reduce the input gain on the Eris E5 and increase the output level from your audio source, if possible, to achieve a better signal-to-noise ratio.
- Popping Sound on Power On/Off:
- This can be normal for some active speakers. Always follow the recommended power on/off sequence: turn on audio source first, then monitors; turn off monitors first, then audio source.
- Distorted Sound:
- Reduce the input gain on the Eris E5 and/or the output level from your audio source.
- Check for damaged cables.
- Ensure the acoustic tuning settings (EQ, Acoustic Space) are not set to extreme values that could cause distortion.
