High and Low Pass filters on Preamp- help!
Howdy Fellow ARians,
I have a B&K Reference 50 preamp that I am still learning how to use. It has functionality allowing customization of the crossover frequency, low and high pass gain as well as the LFE level.
I am having trouble understanding what,exactly, these settings do and how to set them. I understand that my particular room set up plays a big part in this but I was hoping to get some basics so I can at least make a better educated guess on a starting point
My powered sub is connected to the sub out of my preamp. I am running a pair of Allison Four front speakers connected to my NAD 2400 THX amplifier, an Infinity Center connected to my NAD 3150 amplifier (bridged to mono out) and two powered M-audio monitors for my rears. I think I understand that the crossover frequency setting on the preamp dictates the cutoff frequency to the sub- any Q higher than what is set on the preamp will not go to the sub.
However, the high pass, low pass and LFE gain settings have me confused. Would these only apply if I was using a crossover on my sub while sending the higher frequencies from my sub to my front channel amplifier?
Any knowledge and advice is extremely welcome! :)
Thanks for your time and expertise.
