    Do i have to worry about impedance mismatch with a keyboard and the LR-16 recorder, same with guitar amp output, should i use a DI box inbetween?

    It should work fine with line levels.
    With the keyboard works for sure but with guitar that is really depend on the guitar amp output.
    Please make note the LR-16 capable to receive unbalanced signal only.

    Great to know!

    I plan on feeding it mostly Microphone signals from a preamp but didn’t know about the unbalanced only thing, that means every TRS connection will be treated like a mono signal?

    Thank you.

    Hi,

    If you have a TRS output you’ll need to disconnect the “R” (ring) pin from the cable, to connect to the LR-16.

    I only have TRS cables, I understand it will only record each channel as mono. It won’t damage the device using a TRS cables will it?

    Hi,

    The LR-16 will record in mono anyhow. It has no stereo input.
    If you want to use TRS cable with the device you’ll need to disconnect the “Ring” cable from the TRS cable.
    The reason for this because the “Ring” cable is the return signal (insert type of connection).
    Definitely not recommended to feed the device from regular balanced outputs using standard TRS cable, it may damage your LR-16 inputs.

    Understood. Instead of taking apart some of my TRS cables, I think I will just pick up a few of these TS cables and maybe invest in a patchbay. https://www.amazon.com/dp/B0029MZTV2/

    Hi,

    But this one also not good for a LR-16.
    This cable has a TS plug on both two end which means where you connect to the LR-16 it will short circuit the Return pin (ring) to the ground (sleeve) .

    Please take a look for the images in the FAQ

    The image says “R” is not connected, no contact. So how would it do any damage if it’s physically not connected at both ends?

    I don’t know which image says that but this cable has a TS connector on both ends (of course there’s no Ring contact in this case) this means it has two pole Tip (signal) and Sleeve (ground) and this pole is common with the Ring pin.
