I am selling this item because I haven't used it much since I bought it, and my workspace has shrunk, making it cramped. I may repurchase it or introduce a 16 or 12 if my environment changes. The specifications of the product itself are excellent. It offers high-quality effects and simultaneous multi-channel recording, and the sound quality is also high. Its performance as a mixer is also outstanding. It works well with a PC, making DAW work easier. The product itself is in beautiful condition with no scratches. The box and manual are not included. The Model 24 is a new recording solution that flexibly adapts to all situations, such as live performances, rehearsals, and recordings, as a multi-track recorder, mixer, and audio interface, meeting the diverse needs of musicians, engineers, and others. ■ Simple design for intuitive operation The simple and classic design of an analog console, including 100mm faders for precise volume adjustment, user-friendly EQ and AUX knobs, and a 1-knob compressor for natural compression, provides intuitive operability. ■ TASCAM's advanced recording technology The Model 24 is equipped with a multi-track recording engine that incorporates TASCAM's long-cultivated recording technology, enabling simultaneous recording of 24 tracks to an SD card, simultaneous playback of 22 tracks, and simultaneous punch-in/out of 8 tracks.
