How Does Universal Audio's Unison Technology Work?

The built-in DSP (digital signal processing) in Universal Audio's Apollo interfaces allows users to process audio directly at the input stage before it even reaches Logic. The built-in preamps on the Apollo already sound great, but Unison allows plug-ins to be used to emulate classic console preamps, channel strips, and even guitar amplifiers. Unison-enabled UAD preamp, guitar amp, and pedal plug-ins reconfigure the physical input impedance, gain staging response, and other parameters of Apollo’s mic preamp hardware to match the emulated hardware’s design characteristics.
