Yes hot is relative. And relatives like company!
To complete your post, it would be nice if you ran some comparisons (one at high volume would be nice), but also compare it to the temp of your computer, your DVD player idle/playing and so on...
Thanks in advance.
OK, I left the amp running for about 9 hours with the volume on the preamp (a Denon AVR-3806) turned all the way down.
The amp’s temp was 44C.
The Denon’s temp was 35C and my Motorola DCT 6412 DVR, which is always left on, was 36C. Both the receiver and the cable box are in a unit that is closed top, bottom and sides.
Room temp was 21C
The A1400-8’s manual states:
“Precautions: Air flow in the bottom vents and out the top vents of your A1400-8 is very important. Do not block these vents in anyway. Your A1400-8 is designed to operate in ambient temperatures up to 30 degrees C (86F). Since the A1400-8 will actually cool down as you increase the output please be sure to turn off your amplifier in very high ambient temperature conditions when not in use.”
Andrew Marshall in his Audio Ideas Guide review suggests connecting the input of the typically unused 8th channel to a signal source. Would be nice to hear what Axiom recommends.
