Musway is known for building particularly elegant and well-thought-out DSP amplifiers that can be controlled via a smartphone app. The new M12, which boasts impressive 12 Class-D channels and an integrated 16-channel DSP, also follows this tradition. It particularly appeals to audio aficionados  who want to be able to individually tune loudspeaker systems in vehicles for the best possible playback and at the same time be able to control it easily without having to install complex cabling or multiple devices.

For optimal sound tuning, a high-quality input section is required, which picks up the audio signals from the source. The M12 therefore has an impressive number of low-level and high-level input connections. There are not only 6 pairs of cinch inputs and an additional AUX input, but also 12 pairs of high-level inputs, which can pick up signals from the speakers. They can withstand 20 volts RMS and are used when a complex factory system has already been installed in the vehicle. Of course, the fed-in high-level signals are secured with EPS so that no errors occur in the diagnostic system. For hi-fi connoisseurs, an optical PCM input with 192 kHz and 24 bits is available “On Top”. The optional BTS-HD dongle enables HD audio streaming via aptX codecs (576 kbit, 24-bit, 48 kHz).

While the high-end processor supplies the 12 channels internally, the DSP also provides 4 freely configurable RCA preamplifier outputs. These can be assigned to external purposes and open up many expansion options. In this way, additional amplifiers can be included in the DSP performance, for example powerful mono amplifiers that are better suited for driving subwoofers. The Musway mono blocks ONE600 or ONE1000 are particularly suitable for this. The woofers under the seats or in the footwell, which are often installed in BMW or Mercedes models, can be fired up optimally.

At the heart of the M12 is the ADAU1452 processor from Analog Devices®, which is highly valued by audiophile connoisseurs. With the easy-to-use PC software, it can be configured perfectly and in real time via USB. With the optional BTA2 dongle, the DSP can also be controlled with the new ‘Tunest’ app via iOS or Android smartphones (see App Store).
