Amplifier Service Manual
Q:
A: you can try the brand website. most of the brands post their product manuals online if you need it and you've lost the original. Just go to their website and find your product.
I really need the power supply schematic diagram for it. I need to find out how much volts it works with.
I need to replace the transformer but i don't know what to get.
The ACPL-C797 is a significant upgrade compared to Avago's successful first generation HCPL-7860 current sense amplifier. Upgraded features and specifications include a -40 to +105deg C operating temperature range, both 5 and 3.3 V compatible digital outputs, lower offset voltage, a gain accuracy of В±1%, and a В±10% accurate clock frequency. By implementing a digital filter in an FPGA, ASIC or DSP, the serial output is decoded to 12-bit effective resolution. In addition, the new isolation amplifier features 78 dB signal-to-noise ratio and minimizes EMI with a slew rate controlled output.
Please can some one send me a service manual for a harman kardon Hk 640 music amplifier
Thanks, but that is the owner's manual. I need a service manual.

For this review, Yamaha sent its YST-SW315 subwoofer, which sports a beefy 10-inch magnetically shielded cone woofer backed by a 250-watt amplifier.

Its 10 amplifier channels provide 300 watts total output at less than 0.1 percent total harmonic distortion from 20 to 20000 Hz (THD all channels driven). |
