[QUOTE="Deiimos, post: 8924514, member: 682903"] Granted I do not have a DD-1, the manual does not seem to mention anything about impedance, but yes, I presume it just lets you set the amp at maximum un-clipped signal, doesn’t matter what ohm load you run afterwards. The SMD forum came up after a quick search and someone there said it did not matter about ohm load, it sets the amp like I mentioned above to its maximum un-clipped output the amp can provide. If you are aiming for a lower power out of the amp than its maximum, then you still need to use a multimeter to set it at a maximum target voltage. Say you have a clean 5000 watt RMS amp at 2 ohm, and you are running a 800 watt subwoofer at 2 ohm, if you set it with the DD1 you will have 5000 watts out of the amp at maximum volume. If you want the amp to do about 800 at 2 ohm instead of 5000 watts, you would need to use the multimeter to set the output voltage of the amp, with a proper test tone, to about 40 VAC. If just wanting maximum output from the amp, just use the DD1. [/QUOTE]
