The updated Hertz ADC (Advanced D-Class) amplifier achieves up to 85% efficiency and provides 90 W x 4 at 4 Ω or 300 W x 2 bridged at 4 Ω. With its IP55 protection, ultra-compact dimensions, and flexible filters, it is ideal for motorcycles, under the seat of sports cars, or behind the seat in trucks. A signal-to-noise ratio of 100 dBA and precisely adjustable crossovers ensure clear, controlled reproduction – even in challenging installation situations.
