AI Thread Summary
The discussion focuses on bypassing the loudness circuit of a 2006 Subaru Legacy P-204UH radio to achieve a clean line level output. The original tutorial suggests removing specific capacitors and connecting RCA wires to designated pins for optimal sound. However, the user has a P-201UH model, which has a different layout and capacitor labeling, complicating the process. There is a mention of the importance of a clean input signal for audio quality, and the user is seeking help to identify the correct components. The conversation emphasizes the need for a schematic comparison or using an audio probe to locate the appropriate tap point.

Heat up and remove capacitors (see blue) C307, C301, C201, and C207. Simply land your RCA wires to the pins highlighted in red. Purple pin is GND. This should give you a solid 2V line level out. Enjoy your un-eq'd radio:)The above is a tutorial on how to bypass the built-in loudness circuit and get a clean line level out on a 2006 Subaru Legacy P-204UH radio. Unfortunately, I have the P-201UH model. The member who wrote this hack is long gone, so I came here. I popped open my radio only to find that the layout is different. The capacitor values he listed are not on my board. Well, maybe they are, but the labeling numbers are different. Subaru didn't change much until 09' with the 5th generation. I'm hoping this is just another matter of finding a few capacitors and removing them.

Background: Regardless of how much time/money you have stuck into new speakers, external amplifiers, processors, etc... your stereo will only sound as good as the input signal. The loudness circuit needs to go! I want to send a clean line level to my amplifiers.EDIT: I can't open the PDF for some reason. Link to schematic:

Will update when I get at the PDF

Have you compared both schematics and found the corresponding tap point on your stereo?
Or you could make an audio probe for a few dollars and spend a few minutes to find the point that way.
 

Thread '3-terminal device external modeling'

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...

Thread 'Question about the voltage between two charged capacitors'

suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...
