The Eris E4.5 has balanced ¼” TRS and unbalanced RCA inputs, as well as unbalanced 1/8″ inputs for a smartphone or MP3 player. It also offers a four-position Acoustic Space switch controls a second-order shelving filter, centered at 1 kHz, that provides three attenuation points (no attenuation, -2 dB and -4 dB), allowing you to control the bass response relative to the wall proximity of your speakers. A High Pass switch sets the low-frequency cutoff (second-order slope, -12 dB/octave) to be flat, 80 Hz, or 100 Hz. You also get continuously adjustable (±6 dB) High Frequency and Midrange controls.
This combination of controls lets you create a linear response for accurate monitoring. It also enables you to simulate different listening environments, so you don’t have to listen to mixes on your car, consumer computer speakers and home stereo to check how the music sounds with different systems. Instead, you can adjust the Eris monitors’ response and test your mixes without leaving your studio.
The Eris E4.5 lists for $199.95 a pair. Here are all the specs.
