Trying to get the optimal level from the DI to the FOH board. I'm running a Pre DI signal to the house. But I'm confused about setting to unity gain on the amp. According to the manual, "the output is calibrated for 1.0V (0 dBV) output and can be adjusted to unity gain (instrument level) by adjusting the Level control to -15dB (U)." When I set it at unity gain (12 o'clock/-15dB) the signal is present but not nearly as powerful as setting the level all the way to the right (0 dB). This is the sound that I like the best. But will this be too much for the input stage on the FOH board? I need the bass to cut through two keyboards, organ, drums and guitar. It gets buried in the mix. But today in rehearsal when I dialed the DI all the way to 0 dB it sounded great. We record the services so I don't want to overdrive the signal to the board. What are your thought or experience?
