Exposure audio not working
Even without a device to measure sound, you can typically tell if the noise around you is too loud. Top of Page. During pregnancy, use the same precautions specified above for at home and public events. Also try to avoid your body touching the source of the noise i.

Exposure doesnt give any output. Hello, Last year I bought a used Exposure and used for about 6 months. First problem was, right audio channel started to give very distorted sound suddenly. I decided to take it away and try to repair it some time later. After sometime I decided to take the casing out and take a look at the very big output capacitors. However I heard the click sound that I always heard at the startup.
I checked voltage levels and output capacitors had some voltage when turned on. I guess it was 60V or something. What could be wrong with the amplifier? How can I troubleshoot? Should I change all small capacitors on the board?

Last edited by indianajo; 28th April at PM. Thanks a lot for your detailed answer. I just remembered that when I checked to board I found out that one of the fuses was blown.
So I changed it but didn't work out, just fyi. I am actually electronics engineer so I'm not new to soldering. Analog vom is neat trick I'll get one asap. Maybe I can also get a cheap chinese oscilloscope. Unfortunately I don't have digikey here but I'll be able to get things locally. Exposure - Album on Imgur Here I uploaded some photos.

Before I only checked 3. My guess is there was a contact problem on ma fuse. Now how should I test it before connecting speakers?
I forgot to mention in previous post, remote started to work as well. I tried to check speaker output connectors voltage, in AC mode of voltmeter, left channel showed 7. These values didn't change with me increasing volume knob. I decided to check if it works with my old speaker and everything seems working fine now. While everything opened up I checked some voltage levels for future reference. I'll use patricks drawing and opamp pinout to refer pins I'm measuring.
I am writing on the phone sorry for any mistake, and I'll try to write it down as table. On table Ref means where I put my black cable of voltmeter, target means red cable. Do you see anything wrong here? Reason: Formating. You can check output safely with a speaker by putting a non-polar capacitor in series.
Say a uf 50 vnp, or two 50 v capacitors series minus to minus. This would protect your speaker from DC out, at the cost of sounding a little funny. Bass will be missing. Low wattage 1 vac with series polar capacitors just sounds funny, perhaps due to chemical events. DC voltage on speaker is very bad for them, make sure the amp is not doing that before taking the cap out.
The "opamp V-" of Why are there two readings next to the name? One channel A one channel B? Also "opamp out" of to sound extremely wrong. Your meter ground was on the speaker ground wasn't it.
Or on the common terminal of the two rail caps? If the power pins DC voltages are centered around the speaker ground. There are a dozen caps around the op amps, "cap gnd" doesn't mean a lot to me. We all have the pinout of the ne, no need to reproduce it. Datasheet available on datasheetcatalog. You use the analog VOM with a. Scopes are full of electrolytic capacitors that can fail in years.
Don't buy a used one. I do without. Big lie if your circuit is oscillating ultrasonically. I won't buy one. Caps from distributors with a service life above hours, I haven't worn any out yet since I started reworking everything in If you found the speaker fuses blown, it is worth checking power off the output transistors with diode scale or ohms scale.
B-E B-C either. Blown OT's is a very common fault. Zero is very bad news. Emitter resistors often blow with them. Last edited by indianajo; 1st May at AM. Right now amplifier seems to work fine with my Monitor Audio Rx1. I had 1. In the end I only changed fuses so I assume nothing wrong with the board. If a fuse would blown soon I would check transistors as well. Thank you indianajo and patrick for your help.
There is two big Capacitors I assumed negative side of these would be connected to ground. I didn't do much testing. I don't know wether both channel outputs equally and stable. I'm trying to get capacitors from reputable sources as well. However we don't have farnell or mauser here unfortunately.
Most seller do sell cheap chinese caps. It's hard to find panasonic caps for me. Ordering from abroad is not favorable because of the shipping fees and customs process. Last edited by patrick; 1st May at PM. BB code is On.

Protection against the effects of noise exposure shall be provided when the sound levels exceed those shown in Table G when measured on the A scale of a standard sound level meter at slow response. When noise levels are determined by octave band analysis, the equivalent A-weighted sound level may be determined as follows: Equivalent sound level contours. Octave band sound pressure levels may be converted to the equivalent A-weighted sound level by plotting them on this graph and noting the A-weighted sound level corresponding to the point of highest penetration into the sound level contours. This equivalent A-weighted sound level, which may differ from the actual A-weighted sound level of the noise, is used to determine exposure limits from Table 1. If the variations in noise level involve maxima at intervals of 1 second or less, it is to be considered continuous. Cn indicates the total time of exposure at a specified noise level, and Tn indicates the total time of exposure permitted at that level.

Hyperacusis is a type of reduced tolerance for sound. People with hyperacusis often find ordinary noises too loud, and loud noises uncomfortable or painful. The most common cause of hyperacusis is damage to the inner ear from ageing or exposure to loud noise. Hyperacusis is often associated with tinnitus buzzing, ringing or whistling noises in the ears and distortion of sounds. Usually both ears are affected, although it is possible to have it in only one ear. If you have intolerance to sound in one ear only, this should be investigated for an acoustic neuroma a tumour on the balance vestibular nerve. A tumour is more easily removed if it is detected early. However, even if a tumour is found, not all cases require removal. There are no tests for diagnosing decreased sound tolerance.
