What output types are most likely found on a digital mixer?

The correct choice highlights output types commonly associated with digital mixers. USB and FireWire are prevalent in this context because they facilitate the transfer of high-quality audio signals in a digital format. USB outputs are especially popular due to their versatility and compatibility with a wide range of devices, enabling easy connection to computers and recording equipment. FireWire, while less commonly used today, was historically favored for its ability to handle multiple channels of audio simultaneously, making it suitable for professional audio applications.

In the realm of digital mixers, the focus on digital connectivity is paramount, as these outputs enable streamlined recording and playback processes, and integration with digital audio workstations (DAWs). The prevalence of these connections aligns with the needs of modern audio production environments where high fidelity and low latency are critical.

Other options represent different types of connections. HDMI and Optical primarily pertain to video and some audio applications outside of professional audio settings. XLR and TRS are indeed used in audio production; however, they are typically analog connections associated with microphones and instruments rather than digital mixers focused on digital output. Coaxial and Serial, while useful for specific applications, do not reflect the standard connections found on most digital mixers. Therefore, USB and FireWire are the most appropriate options in this context
