Had a Rowland 8T never had a heat problem in 15 yr.
Heat heat and more heat??
My Jeff Rowland model 8 amp seems to be giving off more heat than I can ever remember. The sound still seems great, but the amp gets hot quicker than I ever remember ( heats up the room quickly!) and it is still warm even after several hours after shut down. Any ideas as to what's going on? Is it time for a trip back to Mr.Jeff?

Dave, rather than using an adapter you might also consider simply purchasing a 3-pin male XLR connector and wiring the one connection (black wire to pin 1) yourself. For one thing, that would undoubtedly be a good deal less expensive than using a Cardas adapter. Parts-Express.com has lots of choices of suitable connectors, costing just a few dollars. Good luck.

Thanks guys, I am not comfortable with wiring up XLR connectors. So, my next option is to ask the factory how the heck one is supposed to use this subwoofer with their 'balanced' amp. I have never used the amp in the balanced mode, my preamp is single ended. Frankly, I have never seen a need to go balanced in my home. As a former pro musician, we would run cables that were lengthy to our gear....across full stages etc., these cables were 40-60' in length. The cables were not that well insulated and I can see how running balanced was beneficial. In the home environment, where I am running cables that are what...1.5meters typically ( and VERY well shielded) I just don't get it. The extra expense and hassle for balanced..why?? Now with this issue, I really don't get it! Main question is have I damaged my amp due to the subwoofer hook-up. It seems so based on the heat it is now giving off.Ugh. Al, one more question...could I connect the ground wire from the sub to my preamp, with the other two connections going to the amp? The preamp has a ground connector for a turntable, which I use for that purpose; could I hook up the sub ground there too? |
Daveyf, Curiosity killed the cat. Did you disconnect the Sub from the amp to see if that was the cause of the heat? (I assume the heat is coming from the power transistors heat sink fins on each side of the amp.) If you did disconnect the sub and the amp still runs hot....... Al, (Almarg), If the bias was off for the power transistors of one channel or both, wouldn't that cause the amp to run hot? . Jim |
