PreSonus Studio 1810 18x8 USB 2.0 24-Bit 192 kHz Audio Interface With 18 flexible inputs, 8 outputs, cue mix monitoring on the first of two headphone outputs, and an onboard DSP monitor mixer that's integrated into both Studio One® Artist and UC Surface, the Studio 1810 delivers superior audio and the features electronic music producers and DJs need. High-grade digital converters, ultra-low-jitter clocking, and our famous XMAX preamps add up to a superior recording and listening experience. The Studio 1810 audio interface operates at up to 192 kHz for ultra-high-definition mixing and recording. High-quality converters on every input and output provide 115 dB of dynamic range to capture complex musical harmonics smoothly and naturally with no audible distortion. XMAX Class A microphone preamps deliver incredibly high headroom, deep lows, smooth highs, and a rich overall sound so you'll hear every breath, transient, and detail in your recordings, making it ideal for both vocal production and sampling. In addition to XMAX mic preamps, the first two Studio 1810 inputs provide instrument preamps so you can directly connect guitars and basses without a D.I. box. All four combo connections feature line level inputs with 40 dB of gain for low-level line devices, like that TR-808 you snagged off Craigslist. Four direct-to-ADC balanced line inputs are ideal for connecting synthesizers, outboard preamps, and channel strips. And the Studio 1810 audio interface is equipped with eight channels of ADAT Optical input (four channels at 96 kHz), enabling you to expand your inputs with an 8-channel converter like our premium-quality DigiMax DP88, so your recording system can grow along with your synth collection. The first of two high-powered headphone outputs features Cue Mix A/B so you can choose between two mixes with a button press, providing the flexibility you need for live DJ performances and studio collaboration. In addition to L/R main outputs with front-panel Mute and level controls, you get four balanced line outputs for monitor mixing plus stereo S/PDIF digital I/O. All line-level outputs are DC coupled, enabling them to send control voltages. An 18x6 monitor mixer lets you create three stereo near-zero-latency monitor mixes. Studio 1810's audio interface's MIDI I/O enables connection to a keyboard, sound module, or control surface, as well, making this versatile interface the heart of your studio. The Studio 1810 audio interface works with virtually all Mac and Windows audio-recording software but it really shines when used with the included PreSonus Studio One Artist DAW. Built by creative people for creative music production, Studio One is easy to learn and enables you to compose, record, and produce your masterpiece without getting distracted by the tools. The mix controls for the Studio 1810's onboard monitor mixer are seamlessly integrated into Studio One.
