What do I set my HPF and LPF filters to?
Paul Silver MemberUsername: StamantPensacola, FL USA Post Number: 184Registered: Sep-04Posted on Friday, June 16, 2006 - 00:13 GMT I have an ED NINe.2x amp and a Premier 740mp head unit. I am having alot of trouble set the adjustments. Are there certain steps in setting the gain and filters? The amp has Gain, LPF, HPF, and a Xover switch which has a selection for HPF, LPF, and Full. The head unit also has HPF and an option for SFEQ. I have tried adjusting myself and I feel I'm making it worse. The dumb--*ss's at my local car audio shop had no idea how to properly tune my mids and highs so I'm looking to the experts here.

Paul Silver MemberUsername: StamantPensacola, FL USA Post Number: 187Registered: Sep-04Posted on Friday, June 16, 2006 - 03:09 GMT Can anyone help me with my mid and high amp? I know this is a much talked about thread. But, they are all on sub amps.

aamir aijaz New memberUsername: Aamir_aijazLahore, Punjab Pakistan Post Number: 2Registered: Jun-06Posted on Wednesday, June 21, 2006 - 11:13 GMT I am using sony sound forge to convert mp3 songs to wav format. But the problem is i cant get the bass and treble to the desired levels. I use graphic EQ then Wave hammer and then normalize. Normalizing makes the bass go down or clips the signal. What should i do.

The idea of a SSF filter is to protect a ported sub from recording errors (like crackle, skip or thump)because those are usually of a much higher output and lower frequency (below 20 hz) than the rest of the recording. I run mine down to 20hz with a slope of 48db/octave but not all amps can do this. Polo.. :-)

Polo Gold MemberUsername: Safe_crackerChicago, IL US Post Number: 1251Registered: Jan-06Posted on Wednesday, June 21, 2006 - 14:49 GMT LPF is controls how high the sub will go not the low. A HPF on a sub amp will control how low it goes and double as the SSF. A HPF allows everything above it to go through say for instance it was 25hz, your sub will see 25hz and above. Now the LPF will control how high your sub will actually go like say 80hz. You usually set the HPF with a steep slope say 24db/octave because you are trying to protect the sub from damage and a 12-18db/octave on the LPF because you want it to kinda "blend" in with your mids. The steeper the slope (db/octave) the less your sub will creep into the neighboring frequencies. Polo.. :-)

Polo Gold MemberUsername: Safe_crackerChicago, IL US Post Number: 1253Registered: Jan-06Posted on Wednesday, June 21, 2006 - 22:04 GMT If it is on a SUB amp with a ported box, no. Some amps have it listed as a SSF but serves the same purpose while others just don't have them at all. Related Threads:
