The IN5E from SM Pro Audio is a multi-channel USB interface that provides a solution those users needing to connect a multitude of different devices, either for mixing duties or for connecting to a computer. Sources can include condenser microphones requiring phantom power, turntables, keyboards and modules, and for monitoring, two sets of headphones and dedicated monitor outputs.

Three front-panel microphone inputs feature individually switchable phantom power, peak lights and gain controls, along with individual inserts for externally processing each input. Phono inputs with RIAA equalization and level controls negate the need for an external phono interface for those wanting to digitize a vinyl collection. The switchable RCA inputs can also be set as inputs for MP3 players, DAT recorders, MD recorders, etc.

Two pairs of balanced line inputs feature 20dB pads, and switches (found on all the channels) route the incoming audio either to the main outputs, or to a recording channel within the USB stream for sending to a computer-based DAW. And for fixed installations, the IN5E provides the ability to input three audio channels using Violet Audio's proprietary protocol for sending audio streams over a single CAT5 cable, without any degradation (requires an optional transmission plate).
