Furnished with studio-class 24-bit / 192 kHz conversion, the Apollo Solo USB gives musicians, producers, and songwriters the appreciable value of high-resolution recording and mixing with distortion and dynamic performance beyond its price point. The interface features two XLR-1/4" mic/line combo inputs and a 1/4" Hi-Z input, all with Unison integration for precise UAD emulations of classic analog preamps. Impart vintage character of your choosing on microphone and instrument recordings while bypassing the unpredictable nature of old equipment. Thanks to the switchable low-cut filter, pad, polarity inversion, 48V phantom power, and stereo linking on each analog input, you can efficiently optimize your incoming signals with straightforward buttons on the Apollo Solo USB's face. It offers a dedicated stereo monitor feed and a front-panel headphone output, plus full input and output metering capabilities. The built-in SOLO Core processing allows you to monitor and record audio using classic analog emulations with near-zero latency. The plug-in bundle included with the Heritage Edition empowers you with 25 top-notch plug-ins ranging from vintage compressor and EQ collections to virtual guitar/bass amps and time-based processors. The included Console application provides control and recall of all interface and UAD plug-in settings including channel-strip presets, drag-and-drop functionality, and dynamically resizable windows. Please note, the Apollo Solo USB requires an external power supply (included) and a USB 3.0 port on your computer in order to operate.
