Used for recording. I am selling one of the two units I own because I no longer need it. The sound quality improved so much that anyone can tell the difference. When connected to a PC, the sound quality of music from YouTube and other sources becomes incredibly high. There is a slight dent on the side, but overall it is in good condition. Includes the main unit, a 1m USB cable, and an AC adapter. The USB cable is a high-end OYAIDE cable. ▼OYAIDE USB Cable https://www.soundhouse.co.jp/products/detail/item/155912/ ▼Product Details https://www.soundhouse.co.jp/products/detail/item/250896/?srsltid=AfmBOoqOHp4dvrR-iKAa2BsDd5b_-GOOA2exjriVOFKRKlGwz06VTHgv ・24-bit/192 kHz USB 2.0 audio interface ・Class-A D-PRE microphone preamps x 2: +48 V phantom power compatible ・Rupert Neve Designs transformers x 2: Switchable for each input ・Analog XLR/TRS combo inputs x 2 (input 1 supports guitar Hi-Z switch), TRS line inputs x 2, independent level headphone output ・Latency-free DSP monitoring effects: Channel Strip / REV-X Reverb / Guitar Amp Classics (VST 3 plugin version included) ・dspMixFx mixer application: Windows / macOS / iOS compatible ・MIDI input/output ・Sturdy full metal body ・Cubase AI download version (Mac / Windows, 64-bit environment only), Cubasis LE for iPad included ・Cross-platform compatible: Windows / macOS / iOS (Apple iPad Camera Connection Kit, Lightning to USB Camera Adapter, Lightning to USB 3 Camera Adapter, etc. required) ・Loopback function
