PreSonus Eris E3.5BT Bluetooth 3.5" 2-Way 25W Nearfield Monitors (Pair)
The PreSonus Eris E3.5 is a pair of 3.5" 2-way 25W nearfield monitors designed to provide a compact sonic reference system for musicians, producers, and audio engineers in home setups, project studios, and commercial facilities. Each monitor produces a frequency response of 80 Hz to 20 kHz via a 3.5" Kevlar woofer and a 1" silk dome tweeter powered by a 25W class AB amplifier. The monitors can handle 100 dB maximum peak SPL. A rear bass-reflex port provides enhanced low-frequency range.
For inputs, the monitor system accepts balanced 1/4" TRS, unbalanced 3.5mm, and unbalanced RCA inputs. An integrated 2-band AEQ allows you to fine tune the monitors to your listening preference. The AEQ controls include ±6 dB gain at 100 Hz and ±6 dB at 10 kHz. A front-panel 3.5mm stereo mini-jack is provided for easy headphone monitoring.
Equipped with Bluetooth For extra usability these speakers are set to cater for all your listening needs.
Each cabinet uses resonance-suppressing internal bracing to optimise the sound output and the amplifiers include RF interference, output-current limiting, over-temperature, transient, and subsonic protection circuits.
