Hi guys. I’m wanting to plug into my DIY home theater subwoofer (just for fun). I’ve got a Rumble 100 as my main amp, but am curious to see what my bass would sound like through my HT sub. For reference, it’s a 15” Dayton driver with a 500w plate amp in a ported box. For movies and music, it’ll get with it. I think I need a DI box to plug into the amp - it only has RCA inputs. From my understanding, I’d need something to “drive” the signal from my bass before the amp could do anything worthwhile with that signal? I see the Behringer DI400 and BDI21 mentioned frequently as budget options. Would any one of these be better than the other? There’s less than $10 difference in the price retail. I don’t want to spend a bunch for something that’s more or less an experiment.
Could you not just use the XLR out from the Rumble 100 and an XLR-to-RCA converter?
I didn’t know that was an option - I’m still very new to the music side of things. That should work, and is cheaper as well. Thanks for the suggestion!
There are some things to consider, though if this is just an experiment, this is probably the most cost-effective means to it.
The XLR is line-out, but the master volume on the Rumble controls the signal level. So, to increase the signal going to your plate amp, you have to turn up the Rumble itself - which may or may not be what you want.
That should work for just an experiment, that way I’m not having to mess with the gain on the plate amp for the sub….the volume on the Rumble is much easier to access than the gain on the sub amp.
looks like you have your answer but basically you probably need some sort of pre-amp before you connect to your Sub. Your Rumble can act in this capacity - but it may not be the prettiest sound if that is what you are going for.
do you have a small mixer laying around? borrow one from a bandmate? that would sure help as it has a pre-amp (trim) built in as well as more granular control over signal. (EQ/volume/compression/effects etc)
Ideally you would still use a DI though. not a bad idea to have one in your gig bag anyway as then you can connect to most systems.
