Believe these are on sale from member Timebomb here.

These definitely deserve a thread.

@Timebomb, are these dual PSU?

What's max current draw @ 8 ohm per channel?

Single power supply driving all 4 channels, supply is rated at 7KW continous, current draw depends on the actual load and the crest factor of the signal, they will not do full power sinewave with all channels driven, the current limiter kicks in.  Max draw is around 32A though.  They will run a 132V RMS sine wave for several seconds on a single channel on a 4 ohm resistive load.  With 2 channels the current limiter kicks in slightly earlier but they nearly manage it.

In real world use RE will rise with that kind of power and there is crest factor in the signal, it is quite different to driving a resistive load,  i will have more detailed tests done in the next few weeks.

@timebomb are these capable of any output into 2ohm on one channel or do they go straight into protect?

32A consumption with a 7KW continuous PSU would seem reasonable.

Out of interest, are the output stages happy driving constant voltage distributed lines? ( "100v line" ) an RMS output of 130 odd volts would be ideal for that kind of use.

Do you have a DSP equipped version on the way?

The Saturn 10s are rated for 2 ohm use,  the Saturn 16s are stated as 4 ohms minimum as the very high power levels would be too much for the output modules (around 7KW).  They are stable at lower power levels however, and should be fine if the VPL is set lower, but i think it is best to advise 4 ohms minimum for the Saturn 16s. 

I have not tested them into high impedance loads so i will have to get back to you on that Chris,  there is a DSP version coming in the next few months with a new module from Germany.

@Timebomb,  can the amplifier be supplied with 32A Powercon in?
Also how many output devices are there per channel?

dial the VPL back to 93V and it should in theory be okay into 2R. let us know if you can test this. or happy to field test for you Big smile

I will do some more testing at 2 ohms,  but imo its best not to run any amp below 4 ohms, its not really ideal, it can be done to get you out of a jam but i would not recomend designing systems to run like that.

The DSP module is not from AllDSP it is from another company in Germany, i will give more details when everything is finalised, i only have the old version of the software at the moment.  

The amplifiers have a captive power cable so the 13A plug can easily be replaced with a Ceeform or Powercon, and i would recommend it for high power use.

what is the CSA of the power cable ? - presumably if it comes fitted with a 13A plug it is no larger than 1.5mm. Obviously this is going to be an issue with a 7KW continuous rated PSU!
