Features:
- Highly efficient amplifier with high output power of up to 240 Watts RMS @ 2 Ohms per channel for impressive dynamics and powerful sound
- Bridgeable output channels for flexible system configurations and maximum power output
- Very compact design for space-saving installation
- Start-stop capability down to 6V supply voltage for uninterrupted performance
- Integrated active crossover with high- and lowpass filters as well as input mode switch for optimal system configuration
- DirectDSP function – input signal bypasses the integrated, active crossover and is routed unfiltered to the output stage of the amplifier
- Smart highlevel input with ADEP.3 for trouble-free integration into OEM sound systems
- Advanced Class D concept for high efficiency and low heat dissipation
