Complete your Eris small production system with the Subwoofer designed specifically for the task. The compact front-firing Sub 8BT delivers smooth, punchy lows to compliment your two-way Eris studio monitors (sold separately) for your bedroom studio, video production, or hi-fi gaming system. The 100-watt amplifier produces knee-buckling lows down to 30 Hz, enabling you to monitor the full frequency spectrum, creating better mixes that transfer well across the widest range of listening environments. Integrated Bluetooth® 5.0 wireless connectivity makes it easy to slide the Sub 8BT into your current Eris BT system. It's also compatible with any other full-range system thanks to back panel 1/4" and RCA stereo inputs with pass-through. Send your source output to the Sub 8BT, connect your full-range monitors to the pass-through, and enjoy. The continuously variable lowpass filter allows you to set the sub's effective operating frequency between 50-130Hz for a seamless crossover transition with a variety of full-range monitors. And when you want to push the system to enjoy the sonic power of your project, do so without worry, as the Sub 8BT's internal limiting, temperature, and transient protection prevents bad things from happening to good bass.PreSonus ERIS-SUB-8BT Features:8-inch composite low-frequency driverBluetooth® 5.0 wireless audio stereo input100W RMS, Class AB power amplifier30 Hz to 200 Hz frequency response103 dB SPL (Peak, @ 1 meter)Input gain control (-30 dB to +6 dB, continuously variable)Continuously variable lowpass filter (50 Hz to 130 Hz)Defeatable highpass filter removes frequency content below 80 Hz from the full-range signal sent from the Eris® Sub 8BT outputs to the main speakersLeft and right, balanced ¼-inch TRS and unbalanced RCA main inputsLeft and right, balanced ¼-inch TRS and unbalanced RCA pass-through outputs for connecting satellite speakersPolarity invert switchProtection: RF interference, output-current limiting, over-temperature, turn-on/off transient, subsonic filterPower Saver mode (engages after 40 minutes) PreSonus Eris Sub 8BT Compact 8 Active Studio Subwoofer with Bluetooth.
