darren509 Posted August 22, 2009 Report Share Posted August 22, 2009 how do u use a oscope to tune your amps at different ohms such as 4,2, & 1 ohm Quote Link to comment Share on other sites More sharing options...
iTech Posted August 22, 2009 Report Share Posted August 22, 2009 That is interesting. How would you do that? No speaker leads can be connected to the amp while setting it up so is it the same with different ohm loads?

How would you do that?No speaker leads can be connected to the amp while setting it up so is it the same with different ohm loads? this is a good question. i was gonna say yes, but then i thought about it alil more... im not sure, i know steve made a video, to help us out, but i dont think theres any distinction when it comes to ohm load. wait for more experienced members to chime in.

I was about to tell the guy, "why would it be different?", but then gave it more thought. Quote My Official Feedback Thread PSN - tech2332 Games for PS3: Killzone 2, BattleField: Bad Company 2!

ISO Posted August 22, 2009 Report Share Posted August 22, 2009 Are you talking about that special feature that is on the Velleman Scope's? I don't think that is useful. If you are wanting to play a subwoofer into a test tone and set your gain on the amp to that one specific test tone I can help.

ISO Posted August 22, 2009 Report Share Posted August 22, 2009 http://www.stevemeadedesigns.com/board/ind...=23462&st=0 If you read through this it should answer most of your questions. The first big section I did covers how to figure impedance rise. The 2nd big section touches on O-scope use. On page 2 Boone's post tuoches on setting up for SPL. On page 2 the last 2 big sections I did cover setting your gains with an O-scope when you are useing a bass boost knob.(mostly for RF amps) After that an explanation about setting up an amp that has a line level controlable dash knob. 90% of the amps out there use these. I reccomend useing a 0 DB test tone recording but I believe you are fine all the way up to 5% distortion test tone recordings. and I use 50 hertz test tones. link is probably more info than you need but it should answer most of your questions.

ISO Posted August 22, 2009 Report Share Posted August 22, 2009 I don't figure the ohm load into the equation and practice of setting gains.
