can i use the l272m op amps i have?
Simply look at its datasheet.if the tda2003 drove the small speakers then how can they be 4.3w when the tda2003 is a 10w amplifier?
Now, when we are done playing audiogurus games, we can get this done.Retched is WRONG:
1) Do not use a bandpass filter for your tweeters. They need a highpass filter.
2) Do not connect a capacitor parallel to the woofer to make a lowpass filter. Instead an inductor is connected in series for a first-order filter, then additionally a capacitor can be parallel to the woofer for a second-order filter.
It is a dual power opamp used for driving the tilt coils in a monitor and motors, not for audio because it has fairly high distortion and it does not produce high audio frequencies.can i use the l272m op amps i have?
Quoted from you: "With the filter caps, you can connect them across the terminals at thee speaker." That is a capacitor shorting the output of the amplifier at high frequencies, not a passive crossover filter.I didn't say to put a cap in parallel. (even though I should have said inductor)
You said "mid" but there are no mid-range speakers, there are a bunch of little 3" tweeters and one 6" woofer. A bandpass filter is not wanted.I didn't say to use a bandpass on a tweeter.
I have used hundreds of TL072 dual audio opamps and had tens of thousands of audio equalizers made with TL074 quad audio opamps. I have never heard of a TL272 and datasheetarchive.com also never heard of it.can you confirm the crossover chip TL072 or TL272 thanks
Which is where the confusion lies. I was apparently going too fast and was trying to say:With the filter caps, you can connect them as across the terminals at the speaker.
ld me to believe they were talking about 2 speakers inside the satellite enclosure, the mid and tweet, then the woofer in the sub.im going to connect 2 speaker in parallel which think the speaker are 4ohms each.
The TL072 dual opamps are labelled U1 A and B, U2 A and B, U3 A and B and U4 A and B. you need a 5th TL072 plus one TL071 single opamp.those TL072 schematic do i use both or just one?
