I'm trying to hook up my compressor, which has XLR outputs only, to a
Kurzweil Rumour, which accepts only TS or TRS connectors. I've tried
using an XLR to TS cable with no luck, as the sound coming into the
Rumour sounds trebly and thin, with very little bass response.

If I were to use an XLR - TRS balanced cable, would I be able to
connect these two units correctly and get the full signal to the
Rumour? Any help is greatly appreciated.

Thanks,
Greg
