Hello All: I have a very simple question regarding the Zoom R16 XLR combo input jacks. The Zoom R16 documentation appears to state that when you use an XLR connection to the combo jack, it is a balanced signal. The documentation is not so clear on whether the 1/4" port provides a balanced TRS connection. If I could find a schematic of the input bus for the R16, the answer would be easy to see. I have seen conflicting info in a few forums regarding this, and I was hoping to find out for sure. Does anyone know the answer to the question? Or (better yet) is there a schematic out there that someone can share? Thanks in advance for any assistance Quesne These are the only descriptions I see of the input ports from the user manual: XLR/standard phone combo jack x8 Input impedance: (Balanced input) 1K balanced, 2 hot (Unbalanced input) 50K unbalanced 1 equipped with Hi-Z switch, input impedance 470k (Hi-Z on) 2 equipped with phantom power switches Input level: –50dBm < continuous < +4dBm Supports input from a variety of sources, including guitars, mics and line level instruments. The 8 onboard jacks, which accept XLR and standard phone plugs, include one high-impedance input and two with 48V phantom power. From high-impedance guitars and basses to dynamic and condenser microphones and line-level devices like synthesizers, many sources are supported.
