The M4+v3 product is a 4-Channel DSP Amplifier from Musway. It utilizes a newly designed Class D technology that is immune to electromagnetic interference, and a 4-layer coated circuit board in a compact housing measuring 150 x 44 x 220 mm. The four bridgeable power outputs deliver 4 x 100 Watts RMS at 4 Ohms or 4 x 135 Watts RMS at 2 Ohms, as well as 2 x 270 Watts RMS bridged at 4 Ohms, with a total output of 540 Watts RMS. An intelligent high-level input with EPS, start-stop ready, and automatic power-on function are integrated. Signal processing includes a Burr-Brown PCM3168A converter and an Analog Devices ADAU1452, controlled by dual 32-bit, 330 MHz DSP technology via the V3 DSP software. Specifications include soft clipping in 2 Ohm operation, a signal-to-noise ratio of ≥ 90 dB, a frequency response of 15 Hz to 22 kHz (-3 dB), and a total harmonic distortion of ≤ 0.1% (1 kHz, 4 Ohm, 90% power). The connection variety includes 6 high-level inputs, 6 RCA low-level inputs, 2 AUX/RCA inputs, 1 optical stereo input, 4 amplified speaker outputs, and 4 pre-amplifier outputs configurable via DSP. A wiring harness with ISO connector is included; plug and play with vehicle-specific wiring kits, optional Bluetooth USB dongles (BTS, BTS-HD, BTA2), and the digital remote control DRC1 with OLED display are available.

Frequently Asked Questions about M4+v3

What power does the Musway M4+v3 provide at the speaker outputs?

The Musway M4+v3 4-Channel DSP Amplifier delivers an impressive power of 135 Watts RMS per channel at an impedance of 2 Ohms at its speaker outputs, resulting in a total output power of 540 Watts RMS. At 4 Ohms, it offers 100 Watts RMS per channel. The bridged configuration allows for two channels to operate at 270 Watts RMS each. This high power makes it ideal for upgrading existing sound systems to produce powerful and clear sound.

What signal processing features does the Musway M4+v3 DSP Amplifier have?

The Musway M4+v3 DSP Amplifier utilizes Dual 32bit, 330 MHz DSP technology through the Analog Devices DSP (ADAU1452), enabling precise and flexible sound processing. With the new V3 DSP software and the V3 app, extensive settings can be made. The Burr-Brown converters (PCM3168A) ensure high-quality signal conversion. Features such as the DSP-controlled preamp outputs and soft clipping in 2 Ohm operation also contribute to optimal audio quality.

What are the dimensions of the Musway M4+v3 and where can it be installed in a vehicle?

The Musway M4+v3 has compact dimensions of 150 x 44 x 220 mm, making it ideal for installation in tight vehicle environments. Typical installation locations could be the trunk or under the seat, with placement ensuring adequate ventilation to avoid overheating. Due to its small size, it also fits in vehicles with limited space without compromising functionality.

How does the high-level input of the Musway M4+v3 work?

The Musway M4+v3 is equipped with an intelligent high-level input that features an Error Protection System (EPS). This input allows the signal to be taken directly from OEM factory radios by down-converting the high signal levels without distortion. The EPS protects against potential errors that may occur during installation or operation. This feature is particularly useful for interference-free connection to existing car radio systems.

What input and output options does the Musway M4+v3 offer?

The Musway M4+v3 offers numerous input and output options: there are six high-level inputs, six RCA low-level inputs, and two AUX/RCA inputs. Additionally, it has an optical stereo input for digital connections. On the output side, there are four speaker outputs, and there are also four preamp outputs/RCA configurable via DSP. This variety of connections allows for flexible integration into existing sound systems and expansion with additional amplifiers.

What advantages does the Musway M4+v3 offer against EMC interference in the vehicle?

The Musway M4+v3 utilizes a newly designed Class D technology that is particularly resistant to electromagnetic interference.

The isolation against electromagnetic disturbances is one of the central advantages, allowing for uninterrupted music enjoyment while driving without quality losses from external influences.

Is the Musway M4+v3 compatible with most vehicle models?

With its compact design and the included ISO connectors as well as the optional Plug+Play cable sets, the Musway M4+v3 is compatible with numerous vehicle models. These standard integration options facilitate retrofitting in most vehicles without extensive modifications. Due to the diverse connections and flexible DSP programming, the M4+v3 fits into the modern 4-Channel sound systems of many popular car brands.

What technologies support the audio quality of the Musway M4+v3?

The Musway M4+v3 is equipped with high-quality Burr-Brown converters (PCM3168A) that ensure precise signal conversion. The dual 32-bit DSP technology with 330 MHz enables comprehensive audio processing. The signal-to-noise ratio of ≥90 dB minimizes background noise, while the total harmonic distortion of ≤0.1% ensures clear sound reproduction. These technologies work together to create an excellent audio experience with high fidelity, which is particularly impressive when extensively using the device's DSP functions.

What additional features does the Musway M4+v3 offer?

The Musway M4+v3 offers additional features such as an automatic power-on function that ensures start-stop compatibility, as well as soft clipping for power stability with low-impedance speakers. Optionally available Bluetooth® USB dongles like BTS, BTS-HD, and BTA2 enable wireless audio streaming and control via an app. A digital remote control with an OLED display, the DRC1, is also available to conveniently manage various DSP functions. These expansion options make the M4+v3 a versatile upgrade for any sound system.

How does the Musway M4+v3 improve an existing car sound system?

The Musway M4+v3 enhances an existing sound system by amplifying audio performance with 135 watts RMS per channel, which provides a significant sound boost, especially in factory-installed 4-Channel systems. Through the DSP-controlled preamp outputs, the amplifier can also be used to integrate additional components. Compatibility with high-performance speakers and the extensive DSP technology for customized sound processing enable a tailored sound experience that will appeal to both novices and audiophiles.
