Dsp amplifier D8 V4

The brand new Musway 8-channel DSP power amplifier, the D8v4, not only brings a breath of fresh air to the world of Class D amplifiers with DSP, but also sets new standards in the "extremely compact" category. Outwardly, it looks similar to its predecessor, but a lot has changed under the hood: Musway engineers have made the seemingly impossible possible and increased performance by 40% – without increasing the size of the heat sink. This is made possible by the state-of- the-art Infineon ® power chips , which not only deliver more power but also operate much more energy-efficiently.

With dimensions of only 127 x 207 mm and a remarkable output power of 8 x 100 watts RMS at 2 ohms, the Musway is one of the world's most compact 8-channel DSP power amplifiers in the 100 watt per channel class. Musway itself remains pleasantly conservative when it comes to specifying the power: in the test report of Car & Hifi 02/2025, the test laboratory determined a significantly higher power - in the end, the report showed 8 x 82 watts at 4 and even 8 x 142 watts at 2 ohms.

The D8v4 is of a different caliber, not only in terms of performance, but also compared to conventional plug+play power amplifiers: on the input side, it has an impressive eight high-level channels with EPS that can tolerate up to 18 volts at the input. The heart of the D8, of course, remains the integrated 10-channel DSP, which is extremely versatile and adjustable. The DSP also has two additional outputs that can be used to connect external amplifiers, e.g. to drive subwoofers. The external amplifier can also be operated via a PC or smartphone app using an optional Bluetooth dongle.
