Audio engineers, producers, and musicians looking for a professional studio monitor with a wide stereo image and precision phase alignment will be impressed with the single PreSonus Eris Pro 8, an active 2-way studio monitor which employs a single point-source coaxial design for clear and accurate sound reproduction. This design provides superior phase alignment between components and delivers a wide sweet spot, precise stereo imaging, and symmetrical dispersion patterns. The Eris Pro 8 has unique advantages for Dolby Atmos immersive rooms as well as stereo mix environments.

Two Class-AB amplifiers deliver 75W to the 8" woven composite woofer and 65W to the 1.25" silk dome tweeter, which offers a snappy, accurate transient response. The monitor offers a frequency response from 20 kHz down to 35 Hz for a full-range sound without a subwoofer and plenty of volume (105 dB SPL). The rear panel provides acoustic tuning controls, including a three-position Acoustic Space switch that helps compensate for the boundary bass boost that can occur when a monitor is placed in a corner or near a wall. High and Mid controls help to further mitigate room anomalies, while a low cutoff filter makes it easy to integrate a subwoofer into your monitor setup. Lastly, provisions for wall and ceiling mounts make it easy to integrate Eris Pro 8 monitors into any stereo or multi-channel system.

  Q: 6. This came with the JBL LSR310s kit I just purchased. I was wondering if I can connect the Left and Right speakers to one channel, while connecting the subwoofer to another channel, then control the subwoofer on/off independently of the main speakers or have all 3 on at the same time?

  A: The Monitor Station allows you to program the unit to output in several ways. Speaker selection can be in All On mode (speaker A, B and C can be engaged simultaneously), Toggle mode (speaker A, B, and C can only be selected one at a time), or Subwoofer mode (A and B are selectable, and C can be selected with A or B).

  Q: 7. Can you listen to the 3.5mm AUX In and the TRS inputs simultaneously?
