4 speakers on 2 channel amplifier?
I have a Reloop Dominance 2002. It has two speaker cable outputs and two Speakon outputs, but it's marketed as a two-channel power amplifier. How much output do each channel have? And can I use it to drive two 8-ohm amplifiers and two 4-ohm subwoofers?
Output power: 2 x 480 W, 4 ohms; 2 x 310 W, 8 ohms
1 x 900W, 8 ohm, mono bridged
Outputs: PA speaker cable professional, screw terminals, 6.3mm jack
Kind regards
It won’t work. The two outputs are stable according to only 4 ohms. You would have to pack one of the 8 ohm loudspeakers with a 4 ohm subwoofer to an output, that would be about 2.7 ohms. If one can try carefully, if it comes from the performance specifications, it is not provided.
So you can only run the subwoofers or just the two tops on it. Or you take the two tops parallel to output 1 and one of the subwoofers to output 2. The latter, however, would be rather weak because you then mono-clang with the two tops or Stereo in relation to the subwoofer.
PA speakers usually have a rated impedance of 8 ohms. If you connect 2 per channel, you get 4 ohms.
And then I can do 2 tops with 8 ohms each and 2 subwoofers with 4 ohms each?
The impedance then continues to drop, the power continues to rise and the amplifier is most likely thermally overloaded in full gas.
