I've done some searching on this with not much luck, so if anyone can point me to any past threads or articles anywhere, that would be great (but any replies here are also much appreciated). My question is, with so many different settings for volume control between the bass and amp, what do they need to be at to get the most volume out of it? In my case: I have a EB stingray 5 (active) plugged into the active input jack of my Carvin RC210 (600 watt) combo. I have the 18" cab added onto this combo, but the majority of the time, I'll just be using the 2x10 combo alone. The controls I have to choose from are the volume control on the bass itself, the gain control, the two power amp control knobs, and the master volume. Typically, I will play with medium and sometimes more aggressive playing style, so the gain should be low i guess (like maybe 30-50%?). I saw someone mention in another thread that the volume on the bass guitar should be up like 75-100% to provide a strong signal to the amplifier, but would that be similar to having the gain up really high and probably cause clipping? I can see how having the volume too low would put a big damper on the available power coming out of the amp, but will it still provide a clean signal with the volume cranked up all the way on the guitar? Regarding the power amp control knobs, should they be all the way up at 10 or would that be too much (like having the gain cranked all the way up) and possibly damage the speakers? And a question (or two) for other RC210 owners: When you're running the amp bridged and full range, do you still have control over the power amp? I tried adjusting the high and low power amp knobs and didn't notice any difference. If you're running just the 2x10 cabinet alone on the 600w head, do you run it in bridged mode or something else? And when you're using the 2x10 alone, are you in danger of overpowering it with the 600w head? I've had this amp for a few years now, and I really like it, but i'm about to have to replace one or two of the 10" speakers, and I think it's probably because of having some of the settings too high when just using the 2x10 cabinet alone. thanks to anyone who has taken the time to read all this.
