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. Class D technology High efficiency Low heat generation No active ventilation required Low installation depth Control LEDs for all signal and operating states on the front panel: power ON, DC, signal OK, clipping, fault Volume, treble and bass control accessible from the front (adjustable with screwdriver) Transformer balanced inputs Potential-free amplifier switch-on Monitoring: fuse failure, overload, excess temperature Protection circuit against open circuit, short circuit, overload 230V / 115V AC input voltage (switchable) 48V / 60V DC input voltage / emergency power supply Amplifier is open circuit and short circuit proof 100V and 50V output, earth-free High quality toroidal output and mains transformers All supply lines plugged in, with detachable bolt-on gates
