Additionally, the MOTU M4 features zero-latency direct monitoring, a valuable feature for real-time tracking without any delay.
Sync sources differ between the two interfaces. The UltraLite-mk5 supports synchronization through ADAT, internal, and S/PDIF sources, offering greater flexibility for integrating with other digital audio equipment. On the other hand, the MOTU M4 is limited to internal synchronization, which may be sufficient for simpler setups but lacks the advanced synchronization options of the UltraLite-mk5.
In summary, the MOTU UltraLite-mk5 provides a wider range of sample rates and more versatile synchronization options, making it suitable for more complex studio environments. The MOTU M4, while still offering high-resolution audio and low latency, is geared towards simpler setups with its emphasis on direct monitoring and internal sync. Both interfaces maintain a 24-bit depth for high-quality audio.

Audio Storage & Playback
Memory Card Slot

The MOTU UltraLite-mk5 USB-C Audio/MIDI Interface and the MOTU M4 USB-C Audio-MIDI Interface both come equipped with a variety of features tailored for professional audio production, but they share a notable similarity when it comes to memory card slots: neither product includes a memory card slot.
This absence of a memory card slot in both the UltraLite-mk5 and the M4 means that users looking to record or transfer data directly to or from a memory card will need to find alternative methods, such as using their computer's internal storage or external hard drives. Given that both interfaces are equipped with USB-C connectivity, they offer high-speed data transfer rates, which can help mitigate the lack of direct memory card support by facilitating quick and efficient transfers to connected devices.
When choosing between the UltraLite-mk5 and the M4, potential buyers should consider other differentiating features and specifications beyond the shared absence of a memory card slot to find the best fit for their specific audio production needs.

Power
Power Requirements
AC/DC Power Adapter (Included)	USB Bus Power

The MOTU UltraLite-mk5 USB-C Audio/MIDI Interface and the MOTU M4 USB-C Audio-MIDI Interface differ significantly in terms of their power requirements. The UltraLite-mk5 requires an AC/DC power adapter, which is included with the interface. Specifically, it operates with a power adapter that provides between 12 to 18 VDC at 1 A, and can be either center-positive or center-negative. This means that the UltraLite-mk5 needs an external power source to function, which might be beneficial in a stationary setup but could limit portability.
In contrast, the MOTU M4 USB-C Audio-MIDI Interface operates solely on USB bus power. This means that it draws its power directly from the USB connection to the computer, eliminating the need for an external power adapter. This feature enhances its portability and convenience, making it an excellent choice for mobile setups or situations where minimizing the number of cables and power supplies is advantageous.
