Used Presonus AudioBox iTwo, with box, cable and paperwork including the software download code. I have downloaded it but uninstalled it so I assume that it can be downloaded again but please satisfy yourself that this will work if the software is important to you.
I've also printed out and bound a user manual if you want it.
I've had an email from them confirming that my account has been closed and so presumably the software should be available again using the code.
The spec includes:
Inputs and Outputs
• 2 microphone inputs with low-noise, high-headroom, Class A mic preamplifiers and +48V phantom power
• 2 switchable line/instrument inputs
• 2 balanced ¼” TRS main line-level outputs
• 1x1 MIDI In/Out
• Stereo headphone output with independent level control
Controls
• Zero-latency monitoring via internal analog mixer (variable mix via Mix knob)
• Large main volume knob
• Signal present and clipping LEDs
Integrated Software (see my note above)
• Studio One® Artist DAW software (Mac/Windows) and 6+ GB of third-party resources
• Transfer files wirelessly from Capture for iPad to Studio One
• Compatible with almost all recording software for Mac®
