kenwood amp automatically shuts off
i have a kenwood amp that i have used for 4-5 years and lately it would randomly shut off by itself while in use. when it happens the power light would start flashing until i press power again then it would go back to standby mode. if i press power one more time then it goes back on. depending on my luck, it would either stay on or turn back off after 3 seconds.
has anyone experienced the same thing? please help cuz i'm a newbie! thanks. |

Either bad joints in the output stages, or a bad speaker / wiring. Any
disturbance in the outputs, or significant drop in load impedance, will result in this protect mode engaging Geoff "netwebcenter" wrote in message ... i have a kenwood amp that i have used for 4-5 years and lately it would randomly shut off by itself while in use. when it happens the power light would start flashing until i press power again then it would go back to standby mode. if i press power one more time then it goes back on. depending on my luck, it would either stay on or turn back off after 3 seconds. has anyone experienced the same thing? please help cuz i'm a newbie! thanks. -- netwebcenter |

Make sure your speakers are 8 ohms, if they go any lower, like from
paralleling speakers, that will drop the ohms to 4. Which can trip the amp. ----- Original Message ----- From: "netwebcenter" Newsgroups: sci.electronics.repair Sent: Monday, August 15, 2005 2:18 PM Subject: kenwood amp automatically shuts off i have a kenwood amp that i have used for 4-5 years and lately it would randomly shut off by itself while in use. when it happens the power light would start flashing until i press power again then it would go back to standby mode. if i press power one more time then it goes back on. depending on my luck, it would either stay on or turn back off after 3 seconds. has anyone experienced the same thing? please help cuz i'm a newbie! thanks. -- netwebcenter "netwebcenter" wrote in message ... i have a kenwood amp that i have used for 4-5 years and lately it would randomly shut off by itself while in use. when it happens the power light would start flashing until i press power again then it would go back to standby mode. if i press power one more time then it goes back on. depending on my luck, it would either stay on or turn back off after 3 seconds. has anyone experienced the same thing? please help cuz i'm a newbie! thanks. -- netwebcenter |
