I've been running an SVP-Pro for a few years now. I joined a new band recently and send a post-EQ signal to the board using the XLR balanced output on the SVP-Pro. The sound guy for my new band has been complaining that he's getting a weak signal. I did a search and found a few comments regarding this, but thought I would ask... Is it common for this pre to send a somewhat low level DI signal? If so I can run it into another DI to boost it... or maybe there's a problem with the pre...?
