If you use the 4XS as a 2-channel 3-ways filter, there is 1 module inside that isn't used, but the manual says there has to be a module in that bank, but they don't say anything about the PFM. With these settings, your installer can set The Epicenter to provide just the. Can I do this? Aren't there any limitations to the lowest frequency I can set the subsonic filter at/highest value resistors I can use? Thats why weve included our Bass Maximizer and the PFM subsonic filter. air, meaning I should just leave the frequency module bank of 1 of the subsonic filters open. The highest value resistor I know here on earth is. 0Hz is the lowest 'frequency' I can imagine.ĪudioControl crossovers use higher value resistors for lower frequencies and lower value resistors for higher frequencies, so to set the lowest frequency possible, I'd have to use the highest value resistor available. AudioControl The Epicenter Micro Bass Restoration Processor & Line Output Converter w/ACR-4 Wired Controller & 6-Meter 4201570 Extension Cable Included. The only way to disable the built in subsonic filter (since there is no other way to disable it) is to set it to a very very low frequency. : Patented Bass Maximizer Dash mount control Bass restoration lighted display Parametric bass control PFM Subsonic Filter Balanced inputs Bass Output. I prefer disabling 1 subsonic filter, otherwise I'd have to change both modules if I want to change the subsonic frequency. Use the included ACR-4 remote to independently adjust bass restoration and output level. find out on what frequency I have to set both subsonic filters, to become the same effect as 1 subsonic filter at the desired frequency The PFM Subsonic Filter can be bypassed for the truly dedicated, and the 10V+ output voltage setting beckons only the bravest among us. The PFM Subsonic Filter can be bypassed for the truly dedicated, and the 10V+ output voltage setting beckons only the bravest among us. Off course I'll use one of them to protect my subwoofer, but a second one would only lower the bottom-end output even more, even if I pick the same frequency or a slightly lower one. ![]() Now the problem: the signal going to the subwoofer amplifier passes trough both crossovers, so trough both subsonic filters. Patented Bass Maximizer Dash mount control Bass restoration lighted display Parametric bass control PFM Subsonic Filter Balanced inputs Bass Output. With The Epicenter Micro, we’ve adjusted the performance down to 20 Hz and have added the Bypass switch on the top cover for those of you who want to hit some rich unknown low tones. Standard this is set to 30 or 33Hz and off course I want my system to play as low as my subwoofers allow. PFM Subsonic Filter This unique feature is legendary with many AudioControl fanatics for its ability to fine tune the bass response of any system. Those will be used to build a 3-ways + sub setup, but I have a question about them.īoth crossovers work with modules and both have a 'PFM' (AudioControls name for subsonic) module in them. As you can see in my project, I own an AudioControl EQX and 4XS. Audio Control THE EPICENTER Digital Bass Restoration ProcessorYour MP3 player thinks your car stereo is a pair of headphones.
