NXL1000 R1 - Amplifier Module
NXL1000 R1 - Amplifier Module
Here is a new power amplifier from Holton Audio, the NXL1000.
Capable of up to 1500 watts RMS continuous sine wave into 2 ohm loads or it can be operated on lower supply rails to drive even lower impedances!
The amplifier board measures 360mm x 63mm. it can be powered from a https://micro-audio.com/store/product/cobra-s2 SMPS or for the more discerning and the abilities to drive loads lower than 2 ohms continuously the use of a 2KW linear power supply per channel would work well..
The output stage uses 12 super rugged Exicon dual die lateral power mosfets, which in turn are driven by a pair of 36 watt SMD power mosfets mounted on the underside of the main PCB for an iron grip on the output stage Gate's.
Two of the NXL1000 R1 amplifier modules can be used in BTL mode for over 3kW into 4 ohms!
