When too many speakers makes it worse. The truth about phase
Share
Phase is a crucial factor in achieving high-quality sound in car audio systems. It refers to the relationship between audio signals, and incorrect phase alignment can lead to distorted sound. Phase refers to the relationship between the waveforms of different audio signals, and when the phase is not correct, it can cause distortions in the soundstage.
In stereo systems, both channels must be in phase with each other to produce a stable and coherent soundstage. Similarly, phase is also critical in subwoofer systems to prevent low-frequency sounds from becoming muddled or indistinct.
In a subwoofer system, for example, it is important to ensure that the phase of the subwoofer is aligned with the phase of the other speakers in the system. If the subwoofer is out of phase with the other speakers, the low-frequency sounds may become muddled or indistinct, making it difficult to hear individual notes or rhythms. With a powerful subwoofer, the fight between that and your door speakers, the door speakers lose and in extreme cases can become damaged.
One of the challenges of working with phase in audio engineering is that it is often difficult to measure or visualize directly. Measuring phase can be challenging, so engineers use various tools and techniques like phase meters, oscilloscopes, and digital signal processing. The Musway M12 Digital DSP Amplifier is an excellent solution that has a 16-channel DSP and 12 Class-D channels. It can solve phase problems and is user-friendly, with a smartphone app for easy control.
It has six pairs of RCA inputs, an AUX input, and 12 pairs of high-level inputs that can pick up signals from the speakers. The M12 has an Error Protection System that protects the high-level signals fed in to ensure that no errors occur. It has Burr-Brown converters and Analog Devices DSP, dual 64-bit, 295 MHz DSP technology, soft-clipping, a high signal-to-noise ratio, and frequency response, and THD ≤0.05%.
To optimize the sound quality, use a tape measure from the listening position to the speakers, enter the measurement in the time alignment section of the M12 App, use 24db Link_Ril crossovers, and avoid overlapping crossovers. Mute all speakers except two, use a test tone app, play a tone at the crossover point, and change the phase of one speaker to check if it gets louder or quieter. Leave it where it is loudest.
Overall, the Musway M12 Digital DSP Amplifier is an ideal choice for those who want to enhance their car audio experience, particularly those with 12 speakers or more and need the additional adjustments.
