ART Microphone Preamp (with USB Audio Interface Function) Tube MP PS with USB (Tube Preamp and Audio Interface) Purchased from SH Co. about 5 years ago. Immediately replaced the vacuum tube with an electro-harmonix 12AX7 EH GOLD. Currently, it seems to be available by special order for ¥24,200 (tax included). I used it only for live performances to capture the sound of a W bass with a dynamic microphone and play it through a bass amp, so I haven't used it much. *Everything in the first photo is included. ・Microphone preamp unit ・AC adapter ・Original vacuum tube (almost unused) ・English instruction manual ↓Manufacturer's website↓ https://artproaudio.com/audiointerfaces/product/240842/tubempprojectserieswithusb *When listing, I checked the inputs and outputs, but I haven't tested all the functions, so please consider this and purchase with no claims and no returns. ------- Professional microphone preamp, USB connection compatible, phantom power equipped. - Model name: TUBE MP Project Series - Accessories: User manual, original vacuum tube, AC adapter - Input terminals: XLR, 1/4 inch jack - Output terminals: XLR, 1/4 inch jack, USB - Functions: Phantom power, limiter, filter, phase inversion - Adjustable settings: Gain, impedance, output level *Used item. *Please assume that there may be age-related changes, scratches, and dirt beyond what is described. #MicPre
