Ideally, you're sitting in the comfy chair in your own studio when you get ready to mix. If you instead find yourself on the go with a laptop and some basic gear, PreSonus E4.5 powered studio monitors provide accuracy and affordability in a portable package. With 4-1/2" Kevlar woofers encased in solid MDF cabinets, the E4.5 pair becomes a crucial part of a durable, reliable listening station you can use anywhere.
Each Eris E4.5 pair consists of one active speaker and one passive speaker. Primary connections are located on the back of the active speaker, which provides signal and power to the passive speaker through a regular speaker wire connection. One pair of balanced 1/4" TRS inputs and a pair of unbalanced RCA inputs give you flexibility for line-level input. A 1/8" jack on the front of the same speaker allows you to plug in an MP3 player to check how everything sounds on a mobile device.
When you're on the move, you don't always have control over the space you're working in, but the E4.5 has takent that into account. Output equalization is available via two variable tuning knobs, one for high frequencies, and another for mids. There's also a low cut switch offering flat response, or attenuation at 80 Hz or 100 Hz. If you can't quite manage ideal placement of the speakers in your workspace, the Acoustic Space switch helps you tune the action of the rear bass ports so the low frequencies are still hitting on all cylinders. If your work takes you overseas, the E4.5 also has an AC select switch so you can adapt to voltage requirements outside the U.S.
