Who it's for:
For anyone who needs 4 inputs and 4 outputs with flexibility for mics and instruments, independent headphone and monitor volumes, and features for streaming.
What stands out:
It has its own driver with a buffer adjustable down to 4 samples on Windows, so you get very low latency and stability without depending on generic drivers like ASIO4ALL.
You get 4 combo inputs with Ultra-HDDA preamps, and inputs 1 and 2 are set up for plugging a guitar or bass straight in. Two headphone amps with independent volume controls, a separate control for the monitors, loopback and OBS support. It also has physical MIDI I/O for keyboards and controllers.
It comes with Cubase LE and IK Multimedia's SampleTank SE with 30GB of samples.
What's missing:
Only inputs 1 and 2 accept high-impedance instruments. Inputs 3 and 4 are meant for mics and line sources.
Bottom line:
An honest interface for the price, and one of the most affordable ways to get 4 mic preamps plus MIDI I/O. A good pick if you want more channels without spending a lot.
