PreSonus Eris E8 XT 8-inch Near Field Studio Monitor Instruction Manual

1. Product Overview

The PreSonus Eris E8 XT studio monitor is an advanced 2-way near field studio monitor designed for accurate audio reproduction in professional and home studio environments. It features a robust 8-inch woven composite low-frequency transducer for deep lows and a 1.25-inch silk-dome, high-frequency transducer for smooth highs. The monitor incorporates a Hugh Sarvis-designed EBM waveguide, which provides a wider and more controlled sweet spot, enhancing group listening and collaboration. Its larger, ported enclosure extends bass response without introducing muddiness. Acoustic tuning controls allow users to tailor the frequency response to their specific mix environment.

• Ventilation: Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.
• Water and Moisture: Do not use this apparatus near water or moisture.
• Heat: Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat.
• 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.
• Hearing Protection: This loudspeaker is capable of delivering sound pressure levels of more than 85 dB, which may cause permanent hearing damage. Use hearing protection when operating at high volumes.

3. Setup

3.1 Unboxing and Initial Inspection

Carefully remove the monitor from its packaging. Inspect the unit for any signs of damage that may have occurred during shipping. If any damage is found, contact your dealer immediately.

3.2 Placement

Proper placement of your studio monitors is crucial for accurate monitoring. Position the monitors to form an equilateral triangle with your listening position. The tweeters should be at ear level. Avoid placing monitors directly against walls or in corners, as this can exaggerate bass frequencies. Utilize the Acoustic Space controls on the rear panel to compensate for boundary effects.

3.3 Connections

The Eris E8 XT offers flexible input options. Ensure all audio connections are made before powering on the speakers.

• XLR Input: For balanced connections from professional audio interfaces or mixers.
• TRS (1/4-inch) Input: For balanced or unbalanced connections from audio interfaces, mixers, or other audio equipment.
• RCA Input: For unbalanced connections from consumer audio devices.

3.4 Power On/Off

After making all audio connections, plug the power cables into the power inputs on the back of the speakers. Then, flip the power switches to the 'On' position. The PreSonus logo on the front will illuminate.

4. Operating

4.1 Volume Adjustment

Adjust the overall output level of the monitor using the 'Level' knob on the rear panel. Start with a low volume and gradually increase it to your desired listening level.

4.2 Acoustic Tuning Controls

The Eris E8 XT features several acoustic tuning controls on the rear panel to help you optimize the monitor's response for your specific listening environment.

• High-Pass Filter (HPF): Cuts frequencies below a selected point (Flat, 80 Hz, or 100 Hz) to integrate with a subwoofer.
• Low-Frequency Trim (LF Trim): Adjusts frequencies below 1 kHz by -6 dB, -3 dB, or 0 dB to compensate for room acoustics.
• High-Frequency Trim (HF Trim): Adjusts frequencies above 10 kHz by -6 dB, -3 dB, or 0 dB to fine-tune the high-end response.
• Acoustic Space: Compensates for bass buildup that can occur when monitors are placed near walls or in corners. Options include 0 dB (flat), -2 dB (middle of room), and -4 dB (close to wall/corner).

5. Maintenance

To ensure the longevity and optimal performance of your PreSonus Eris E8 XT monitors, follow these maintenance guidelines:

• Cleaning: Use a soft, dry, lint-free cloth to clean the exterior of the monitors. Avoid using abrasive cleaners, waxes, or solvents.
• Dust: Regularly dust the speaker cones and ports to prevent accumulation that could affect sound quality.
• Environment: Keep the monitors in a clean, dry environment away from extreme temperatures, direct sunlight, and excessive humidity.
• Ventilation: Ensure adequate airflow around the rear panel to prevent overheating.
• Transportation: When moving the monitors, use original packaging or suitable protective materials to prevent damage.

6. Troubleshooting

If you encounter issues with your Eris E8 XT monitors, refer to the following common troubleshooting steps:

• No Sound:
  • Check if the power cable is securely connected and the power switch is ON.
  • Verify that the audio input cables are correctly connected to both the monitor and the audio source.
  • Ensure the volume knob on the monitor and your audio source is turned up.
  • Test with a different audio source or cable to rule out faulty equipment.
• Distorted Sound:
  • Reduce the input level from your audio source or the monitor's volume knob to prevent clipping.
  • Check for damaged audio cables.
  • Ensure the acoustic tuning controls are not set to extreme values that might cause distortion in your room.
• Hum or Buzz:
  • Ensure all audio cables are balanced (XLR or TRS) if possible, especially for longer runs.
  • Try connecting the monitors to a different power outlet or a power conditioner.
  • Move audio cables away from power cables or other electrical interference sources.
