If you want to record on the go or want a set of compact monitors for your small home studio setup, the Presonus Eris E3.5 Near-Field Active Studio Monitors are a great choice. With a large frequency response, precision engineered cabinets and premium quality drivers, this is one set of monitors that may look small but deliver full-bodied sound.
The Eris E3.5 monitors have built-in Acoustic Tuning controls, which allows you to shape the response of each monitor to fit in with your own studio environment. On the rear panel, you'll find Mid and High control knobs, which allow you to shape the signal output. Therefore, if you find that either the Mids - centred on 1kHz - or Highs are too powerful (or not powerful enough), you can attenuate the monitor output to create a sweetly balanced sound. Though the aim is to keep the settings as close to 0 as possible, you can add or cut by a huge -6db to 6dB range.
As well as the 2-band EQ section, there is a three-way Acoustic Space switch, which controls a second-order, low shelving filter that cuts all frequency level below 800Hz by an amount of your choosing. Depending on your desired speaker placement, you have the choice of selecting presets of 0dB, -2dB or -4dB. The reason for this is to offset boundary bass boost that occurs when the monitors are placed near a wall or corner, a very useful feature that goes a long way to making things simpler when placing your speakers.

The prevalence of signal interference from various sources in a studio dictated Presonus' built-in speaker protection. With radio-frequency interference, electrical appliances, and heat all playing a part in causing signal degradation, certain measures have been taken to minimise any issues. RF shielding protects against radio frequencies becoming audible; over-temperature protection prevents heat-related issues. Current-output limiting prevents unwanted blowouts should a circuit short or cut out, whilst subsonic protection filters out extreme low-frequency signals that could damage or affect the woofer's performance. Finally, the Eris E3.5 has a "soft startup" feature that prevents 'pops' that can occur when you power up the monitors.
The rear panel is home to a range of connectivity options including balanced TRS left and right inputs; RCA unbalanced line left and right inputs; and bare-wire inputs for each speaker. The balanced TRS inputs are perfect for minimising noise, but the range of options make it easier for you to connect whatever equipment you have easily. On the front panel, there is an unbalanced 1/8" inch auxiliary input for connecting smartphones, mp3 players, or whatever you like, as well as a direct headphone output for silent monitoring.
By offering a range of features that are normally associated with monitors carrying a heftier price tag, it's clear to see that with the Presonus Eris E3.5 active studio monitors, the design team have excelled themselves. If you're looking for a pair of compact studio monitors that are simple to set up, easy to transport and above all sound absolutely stunning, these monitors were made for you.
