Musway D8v4

The Musway D8v4 is a powerful and exceptionally compact 8-channel Class D amplifier with an integrated 10-channel digital sound processor (DSP). Thanks to state-of-the-art Infineon power chips, the fourth generation delivers approximately 40% more power than its predecessor without requiring a larger heat sink. With up to 8 x 100 watts RMS at 2 ohms, this power amplifier is ideal for high-end car audio systems and for enhancing the sound quality of factory-installed audio systems.

The integrated 10-channel DSP enables precise tuning of all speakers via comprehensive equalizer, crossover, and time-alignment correction functions. Eight high-level inputs with EPS protection circuitry enable integration into modern vehicles. Additionally, two freely configurable RCA preamp outputs are available, for example, to drive a separate subwoofer amplifier.

Dynamic Headroom Technology (DHR) provides additional dynamic power reserves, while the efficient Class D circuitry and soft-clipping function ensure high-performance operation. Configuration is performed using the Musway DSP software on a PC or, with an optional Bluetooth adapter, via the smartphone app.
