First-time post, but long time lurker ;) :p Do any of you guys have a good schematic for an NE5532 based tone-control preamp? It's supposed to have at least line-level input and any level of gain between 1x-10x. Mar 19, 2014 · Both the TL072 and the NE5532 prefer inverting over noninverting operation by a significant margin for various reasons, but it is virtually impossible to get both high input impedance and low noise at the same time in an inverting configuration (noise gain is signal gain + 1 to begin with, and high input impedance would require high resistor Apr 1, 2016 · LM1036 NE5532 Stereo Preamp Preamplifier Treble Bass Tone Board DIY Amplifier | eBay I found no schematic, It's not clear what 'Power Seat' is. Is it really possible to just replace the NE5532 by the LME49720 without having to change anything else Aug 9, 2023 · It's simpler, won't inject noise to ground and shouldn't be any problem with the NE5532 at least. Its like somebody pushed the mute button on the bass with those BB chips. The offset null pot is not configured correctly to work with the OPA604s or you could use these all round (you would need to reconnect the wiper of the pot to the negative rail rather than the positive as now). It outperforms most typical operational amplifiers, including 1458, in terms of noise performance, output drive capability, and small-signal and power bandwidths. But it is not very difficult. Preferably use bipolar (DIY version: two back-to-back) or low-leakage types for coupling caps. Myself, I should go for IRF540N/IRF9540N. Apr 16, 2011 · Can someone tell me what a better drop in replacement for the NE5532 might be? I got a DAC kit from China for really cheap and am putting it together. I got a TI NE5532 off ebay. Jul 26, 2020 · @Salas i know, i have the full book since 2015, yet i suspect that what we hear wrong is in lower quality ne5532/4 launched on the market with insuficient quality check by unknown companies or sellers. JRC2068's THD of 0. Check all parameters !! Check all parameters !! Anyway when using other opamps one must take care for good decoupling. Jan 26, 2018 · Due to unavailable components, and budget, I'd like to replace this burned discrete OPamp with a 5532 or a 5534 if needed. Also as ways to explore the sonic virtues or drawbacks of different circuit approaches: pure single ended ("Mountain View"), composite amplifier ("Norwood"), diamond buffer ("Austin"), transconductors ("IPS6"), bootstrapped power rails ("IPS7"), etc. Sometimes I see the speaker's cone movement is not matching to music strock. Overall some correction is required to my attached circuit. I tested the RC4558, RC4580, TL072, NE5532, MC1458S, OP275 Oct 9, 2012 · Q1 = input impedance of NE5532 is about 300k, and is stated as Open-Loop Test Condition in the datasheet. Apr 6, 2020 · NE5532 is easy to beat subjectively, and measurably. Jun 3, 2004 · NE5532 is internaly compensated. I did find this as something new. Even today there are people who prefer it. 1 Overview The NE5532, NE5532A, SA5532, and SA5532A devices are high-performance operational amplifiers combining excellent dc and ac characteristics. I noticed that the opamp used for the audio output was an NE5532. dxyg nlwvt cjogx fwbub ibeenmo atlcw ydyryd nirw unmzekn wupx
