OK, so I have been racking my brain trying to figure out a way to explain how the bass management works and unfortunately there are so many permutations that I thought my head would explode. Which made me think if my head is about to explode and I helped design and build this thing, what is going to happen to everyone else? Then finally it hit me, rather than try to explain every possible permutation, why not just explain how the different sections work. Duh
So hang on to something and I will try not to confuse everyone. The reality is it is really very simple but difficult to explain. But I will give it my best shot.
1. The Sub-woofer EQ or better known as the LFE EQ. In the EQ section as you have probably already seen there is an EQ just for the sub. What you need to know about this EQ is that it only applies to the .1 signal of a discrete code. So what is the .1 signal you might ask? It is the dedicated sub-woofer signal from a multi-channel encoded stream. So if you have a Dolby Digital or DTS signal (or something along those lines) coming in. That bit stream will be encoded with individual discrete channels, one of them dedicated with the sub-woofer signal. So when you adjust this EQ it will only apply to this type of bit stream. Right about now, you are probably asking yourself, what about the summed sub signals? Hang on, that’s coming because they are handled separately.
2. The next thing you should know about is the EQs for each speaker and how they work and relate to the subs. If you have been playing around with the EQs then you have seen that each speaker has its own. Left, Right, Center, Surrounds, etc., they all have their own EQ and crossover. The EQs for each speaker can all be set independently and are full range EQs. Meaning they cover the entire audio spectrum. We did it this way for many reasons. Mainly so that you can set an EQ curve for the entire spectrum and then adjust the crossovers without having to go back in and set all new EQ settings. So you set it for the entire spectrum even if your speaker can’t play full range and here’s why.
3. When you set a high pass crossover for each of your speakers, everything below the crossover frequency will be summed together and sent to the subs. So the EQ settings (for each speaker) below the crossover frequency will apply to the summed bass response.
Thus you have EQs for the summed bass and for the LFE that can be set and tuned independently from each other to be whatever you want them to be.
Well I hope I didn’t confuse everyone, because I really don’t know how to explain any better than that. ;D ;D ;D
I hope this helps and if you see other asking about this, please direct them to this post because I really don't want to clutter up the forum by posting this in 10 different threads.
