If you want a professional-quality audio interface at a wallet-friendly price, consider the MOTU M4, a USB Type-C device designed for recording, mixing, podcasting, and more. Offering loopback connections that allow podcasters to record skype calls with absoutely no fuss, the M4 can feed audio to both computers and iOS devices, thanks to its USB Type-C connection.

With two XLR-1/4″ inputs, the M4 can handle microphones, line-level instruments, or Hi-Z instruments such as guitars and basses. Selectable phantom power is on hand for condenser mics, and the preamps are exceedingly clean with an EIN of -129 dB; this ensures you only hear the instrument or voice being captured, rather than any noise from the preamp. Whether you need a clear-sounding vocal for a podcast or a transparently recorded guitar for a mix, the M4 will deliver the goods.

Professional-Level Audio Quality

Equipped with the same ESS Sabre32 Ultra DAC technology found in audio interfaces the pros use, the M4 delivers 120 dB of dynamic range on its main outputs. ESS converters also drive the headphone output. Ultraclean preamp circuits produce a measured -129 dBu EIN on the mic inputs; this means while recording, you’ll only hear the mic, not the mic pre.
