Hartke LH500 outputs
Recently I bought a Hartke LH500 amp. I have an SWR Triad (400 watts
4 ohms) cabinet and a Hartke HyDrive 112 (300 watts RMS) with a
8 ohms/4 ohms switch. My question is, can I plug each cabinet on each output of my amp?
I would not do it.
You could set the 112 to 8 ohms but you still end up with too low an impedance for the amplifier.
You can use 2 hydrive 112's though.
Not without damaging your amp. The lh500 has a minimum rating of 4ohms total. Putting the hydrive on at 8ohms and adding the triad at 4ohms would bring the total impedance down to 2.7 roughly. The outputs of the amp are wired parallel therefore are not independent of each other.
Also, if you have any questions on how a particular amp operates - refer to the owner's manual. If you don't have one, go to the company's website where they can be downloaded for free.
I would not try it... better to get another matching cab.
So the LH500 has 1 500w power section. If you hook up two 4 ohm cabs you end up wiring them parrallel getting a 2 ohm load, probably too low for the amp to handle. It will burn up.
For the LH1000, it has two 500w power sections at 2 ohms. On this amp it would work running in stereo hooking up one cab to Speaker A and one to Speaker B probably driving
350w per channel.
