Kenwood KR-A4060 erősítő - a védelem fordított logikával működik !
Sziasztok! Na ilyet még nem láttam: a processzor Protect bemenetén alapból L szintnek kellene lenni, üresen 1,5V körül van rajta és bekapcsoláskor azonnal a PROTECT jelenik meg a kijelzőn. Namost a védelmi áramkör aktivitása esetén H szintet produkál, viszont ha mesterségesen adok egy H szintet a proc. bemenetére (Q8 kollektora, szervízkönyv 25.oldal), az esetben hajlandó csak működni az erősítő ! :hmmm: Ilyenkor 4V-os H szint van a proc. 31-es lábán. Megfordult a logika?
Sziasztok! Keresem a Kenwood KRF-A4030 erősítő kapcsolási rajzát. Ha valaki tud segítsen! Előre is köszönöm.
szervusztok ehhez a Kenwood KAC721 tipusu erositohoz keresek kapcsolasi rajzot, az a hiba,hogy nem kapcsol be,az alkatreszek nem zarlatosak, a neten sok KAC rajz van,de ez nincs... koszi a figyelmet
Kenwood KA-3500 Integrated Amp BIAS Adjust
Hello, Last week I picked up a nice Kenwood KA-3500 40watt intergrated amplifier in pretty good shape. Upon using it a bit more, I noticed a bit of distortion at high volume, more so in the left channel. I checked the DC offset at the speaker terminals, and the L channel said 100 mV, while the R was 25 mV. I understand this isn't so good for the L channel at least, but unfortunately this amp doesn't have any DC offset adjustments. Am I right in saying that to fix this I'd have to replace the output transistors? -- On a related issue, in the service manual I found the section on BIAS adjustment, and I read online how it can affect the DC offset. So I hooked up my voltmeter to the test points, and I got 4 mV on the L, and 8 mV on the R. In the manual it says should be 40 mV.....(!). Is there something wrong here? I tried carefully adjusting them, but they only go to 30mV with the pots fully on, this doesn't seem right to me. -- I compromised at 20 mV BIAS for both channels, and now the DC offset is 50 mV for L, and 5 mV for R, which is better, less than half what they were. I'm wondering, will I damage anything doing this, should I put them back to where they were? -- The service manual is on site here. Let me know if you want me to upload an english copy of the Owner's Manual, it has a better schematic in it all on one page, easier to read. I've also included some pictures. They're not my actual unit, but mine is exactly the same, but less dusty. -- Thanks for reading this. Many thanks in advance, and have a peaceful Palm Sunday! :taps2: Bellarmine
