Here's a copy of the service manual. If you look at page 10, there's a Power amp before the speaker and headphone stage. I think this would be the best place to inject the signal, correct? Just click on the document link...

I'll post more circuit pics soon or a service manual with details. It's also got a cd player and radio tuner. It's the sharp xl-s10.

As it stands once the 4pin tape connector is removed, left and right audio channels go directly into pb1p and pb2p of the ic201. Are you suggesting I should bypass this chip as I is causing errors. If this isn't the case, do you think there would be a way of elevating the sound levels for the...

I've completely removed the 4 pin connector for the tape ***. The audio in is now considerably quieter and there isn't any distortion when the pc audio level is at full. I think that that voltage amplified the signal but caused distortion somehow. I think there just isn't sufficient current...

I know this is a physics forum, but someone may be able to help. I have a mini-hifi that I want to use the tape player connections from as an aux in. I've soldered a stereo cable into the connections on the hi-fi as shown in the electronic diagram. The left channel works fine, without any...

Homework Statement This is one half of a load cell I am analysing for an asignment. I have managed to calculate the stress in the beam using the equations below. I have approximated the centroid to be along the red line so that I can work out the distance for M, and then taken y or...

I'm halfway through a course on FEA at the moment, its becoming more obvious that using that mathematics will be the best way to solve the problem, rather than using beam analysis. Sort of answered my own question. Thanks anyway.

Does anyone know how SolidWorks calculates the stresses for this simulation. Can anyone give me an idea, is it second moment of area? y/r = m/i? Thanks Richard.

I understand the characteristics of speakers can be improved by weaving kevlar to form a square pattern and that the sound waves are deflected because the angles on the pattern cancel them out. However, i don't see why this has to be kevlar and not any other material which could do the same...

Hi, if you have a capacitor and inductor in series connected to an Alternating Supply, do their reactances add up? Thanks Richard.

Hi, wondering if someone could help me with the following question. A mass is hung from the lower end of a light vertical spring, whose upper end is fixed. The mass is pulled down and released and the time period of the oscillating system is measured. If the time period is 0.25s and the...

Hi, i don't think i gave enough information in my question. What would the fringe separation look like for white light (multiple frequencies) compared for example to blue light (one frequency). Would it look like a single beam which was bright in the middle and less bright as you went away from...

Hi, I have a physics assignment which is asking me what the fringe pattern would look like if white light was passed through a double slit. Would it look like a single light which became gradually darker the further away it got from the central maximum? Thanks in advance Richard.
