2.1 Đầu vào và Chuẩn bịamps
The Scarlett 4i4 features two high-performance 3rd Gen Scarlett mic preamps, accessible via combination XLR/TRS inputs on the front panel. These preamps offer a switchable 'Air' mode, which emulates the sound of Focusrite's original ISA mic preamp, adding brightness and openness to vocal and acoustic recordings.
Additionally, there are two high-headroom instrument inputs for direct connection of guitars or basses, preventing clipping and distortion. Four balanced line inputs (two on the front with gain control, two fixed-line on the back) allow for recording up to four mono sources or two stereo line-level sources like synthesizers or drum machines.

The interface provides four balanced outputs for monitoring and effects sends, simplifying your studio workflow. High-performance 24-bit/192kHz AD-DA converters ensure crystal-clear playback and recording quality, preserving the sonic integrity of your audio.
Virtual loopback inputs enable capturing a stereo feed of any combination of hardware input and software playback channels, useful for podcasting, live streaming, and sampling
