Jun 27, 2018 · LM3886 sounds good, and Jeff Rowland like produce ampfillers built on this LM. And Arcam FMJ-19 built on LM3886 too. - Much reviews in different audio magazines. So - LM3886 has an output current - 11.5 A And Jeff Rowland put 6 …
Composite amplifier: LM3886 + LME49720 - Page 1 - EEVblog
Feb 28, 2019 · The gains are setup with these in mind: - Use the minimal LM3886 stable gain, which according to the datasheet is ~10. I used 11 just to be sure - Have the LM49710 clip first to get a much nicer clip behaviour without saturating it. Check the attachments for the 2 behaviors: LM3886 clipping or the LME49710 doing the clipping.
How can I calculate the input impedance of an LM3886?
May 14, 2021 · Yes, the inputs to the LM3886 are very high impedance -- basically no current enters them. Adding Rin actually decreases the input impedance of the system as a whole. The resistance to ground is Rin in parallel with a really, really large resistance which is basically Rin.
Topping LA90 Discrete arriving in 1-2 days. Question vs. LM3886 …
Sep 5, 2023 · What's marginally better in the LM3886 (that's what they used, right?) Stereo crosstalk: ~10dB better (discrete is already below -90dB by 5kHz. Like I said "subjectively, performance is the same!" The discrete version is spec'd to run 4 ohm bridge mode, but it's not much of a feat. Why not? Because, 4 ohm bridge gives you 180W @ 1% distortion.
LM3886 guitar power amp design - adjustable output impedance
Jun 17, 2016 · I'm using a LM3886 as the output stage, with +/- 24ish supplies from a 18-0-18 80VA toroidal transformer. I'm also using some current feedback to raise the output impedance, in order to reduce damping and let the speaker flap around, giving a more "valvey" sound.
MicroCap 12: Problem simulating imported PSpice model (LM3886)
Jan 15, 2022 · I have copied to .lib file to the main LIBRARY folder and then used "Add Part Wizard" tool to import the model, I selected the 6 pin op-amp model and renamed the pins as they appear in the model file (.SUBCKT lm3886 Vip Vin VDD VSS Vout MUTE) I constructed a simple circuit and wanted to run the simulation but when I do that uCap shows me the ...

Jun 8, 2019 · As I may know for the Neumann KH120, these loudspeakers are built around the LM3886. There's absolutely no hiss even a few centimeters away. These are proximity loudspeakers (listening distance between 20 and 50cm (8" to 20"))
Upgrade LM3886 to Neurochrome Modulus 686 - Audio Science …
Apr 18, 2024 · I have Kinoshita RM11 replica speakers, bi-amplified by 4 mono blocks attached to the back of the speakers....the compression chambers are powered by 2 amplifiers mono based on Neurochrome Modulus 86, and 40cm bass by 2 …
LM3886 bridge mode... calling all gurus of Gainclone - Page 1
Apr 16, 2020 · Solved the problem... replaced the two LM3886's set up in bridge mode, no more random cases of motor-boating oscillating upon switch-on even after 50 attempts so i hope its ok now. With 400Hz signal applied the scope traces for output + and - come up perfectly together every time even during a very quick power up, off and on...
