The Focusrite ISA One is a microphone preamplifier that delivers professional sound quality. In addition to its use as a mic pre, it was also useful as a DI for guitars and basses. I am selling it because its frequency of use has decreased due to changes in my work environment. The unit comes with the main body and power cable only. - Model Name: ISA One - Brand: Focusrite - Input Terminals: XLR, TRS - Output Terminals: XLR, S/PDIF - VU Meter: Yes - Power: AC 100-240V I hope you will consider it.
