5.1 connections and signal processing

Youngling Posts: 2 Join Date: 4/8/10 Recent Posts

I'm going to buy Genelec 8020 BPM surround set, but I don't quite understand why all the signals are supposed to run trough the 7050B.

Isn't my Yamaha RX-765 supposed to do all the signal processing what is necessary? So why there is a need for 7050B to process the signals also.(I'm going to place center speaker sideways)
What are the main differences if I run signals trough 7050B or if I run signals directly to the speakers?

You must not use both, just either one. The difference with the bass management / processing done in the AV receiver vs Genelec subwoofer is that the very important crossover region between the speakers and the sub is handled in more predictable and accurate manner when done in our subwoofer. This is because we have designed the filters for our speakers and subwoofers, not for some generic speakers and subs like in AV receivers. For example the AV receiver assumes that the speakers you are using have a 2nd order (12 dB/octave) roll off below 80 Hz - that comes from the THX standard. Very few speakers are like that, and definitely not a single Genelec speaker is like that. So the end result is probably not very good, at least if no further means/settings are being utilized to smooth out the crossover area. But for sure a good end result will need more commitment and work from the user. Therefore I would recommend using the Genelec bass management found in our subwoofers/speakers. Remember to set the DIP #2 ON in every 8020B when you route the signal through the 7050B.
