Motu M4 4x4 USB Audio Interface MIDI Bundle with MXL 770 Microphone and HPC-A30 Headphones

SKU CH-MMYM-0DY88

A 4×4 USB audio interface with ESS Sabre32 Ultra DAC technology delivering 120 dB dynamic range, -129 dBu EIN and 2.5 ms round-trip latency.

  • ESS Sabre32 Ultra DAC delivers 120 dB dynamic range on outputs
  • Mic preamps achieve -129 dBu EIN for ultra-clean recording
  • ESS-driven headphone output rivals dedicated amplifiers
  • 5 ms round-trip latency enables real-time monitoring
  • MXL 770 cardioid condenser captures vocals and instruments with low noise

Studio recording bundle

The Motu M4 4x4 USB audio interface ships with an MXL 770 cardioid condenser microphone and HPC-A30 studio monitor headphones. ESS Sabre32 Ultra DAC technology provides measured 120 dB dynamic range on the main outputs and a measured -129 dBu EIN on the mic inputs. The headphone output is driven by the same ESS converters. Round-trip latency is 2.5 ms for live input monitoring.

Build integration

The interface connects via USB and provides four inputs and four outputs for microphones, instruments or line-level sources. A full-colour LCD shows detailed level meters for every channel, removing the need for external metering hardware. The included XLR cable links the MXL 770 directly to the preamp, while the HPC-A30 headphones plug into the dedicated ESS-driven output for independent monitoring.

Upgrade context

This bundle replaces a basic two-channel interface, a separate entry-level microphone and consumer headphones in one purchase. The jump is worth it when a project demands simultaneous multi-source recording with transparent conversion and sub-3 ms latency. It is not for buyers who need more than four analogue inputs or who require built-in DSP processing for effects.

Questions about this item

How does the 120 dB dynamic range on the main outputs hold up during long sessions?

The ESS Sabre32 Ultra DAC maintains that measured 120 dB dynamic range on the main outputs continuously, so sustained use does not degrade the converter performance.

What are the thermal and noise characteristics when the interface runs all day?

The unit has no fan and relies on passive cooling; the ultra-clean preamp circuits keep self-noise at a measured -129 dBu EIN on the mic inputs even after hours of operation.

Which computer port and cable are required to connect the M4?

A USB port on the computer and the supplied USB cable are needed; the interface draws power and transfers audio over that single connection.
