Amplifier 250/300 W & 2 x 250/300 W

Class D technology 

The 1-channel and 2-channel output stages are designed for permanent installation in ELA systems (DS-6, MDK, MF etc.) from Neumann Elektronik.

The amplifiers are designed in Class D technology.
This circuit concept guarantees high efficiency and has low heat generation.

The amplifiers generate a nominal output power of 1 x 250 / 300 W or 2 x 250 / 300 W at an operating voltage of 230 / 115 V AC or 48...60 V DC.
