Re: Intro to bi-/tri-amping
Oops, I didn't realize you were referring to the new XLS Drivecore amps. AFAIK, the DSP in those is essentially useless, only allowing limited crossover and no EQ, am I right?
Mixing DSPs is also a somewhat bad idea, as they could have different latencies which would affect your signal alignment, and depending on what you have to measure with, it could be difficult to compensate for.
In fact, I don't even see a latency spec on the drivecore page, and I am almost sure there are no provisions for EQ. These are a ''DJ'' amplifier, almost completely useless for pro PA use. They might as well not have DSP, because what they have is so limited an external unit MUST be used to get any real features.
So, switching from XLS Drivecore to XTi at least allows you to have a useful amp instead of a pile of junk.
