Crystalclear sound with dual output channels of 120 W each delivers strong, clean audio across the system. Reliable performance across a wide DC input range of 12 28 V, enabling stable, continuous operation in automotive and other DC power environments. Enhanced amplification through TL074C operational amplifier and PA3116 power amplifier for clear, powerful signal amplification. Efficient heat dissipation provided by an aluminum alloy heat sink, supporting extended use without overheating. Common applications Automotive audio systems (cars, vans, trucks, RVs) requiring quality amplification from a DC power source. Marine installations on boats or yachts using 12 28 V DC power. Small venues or background music setups (shops, kiosks, outdoor events) needing reliable, continuous amplification. Key specifications Output: 120 W x 2 channels Input voltage: DC 12 28 V Amplifier chips: TL074C, PA3116 Heat dissipation: Aluminum alloy heat sink
