more. Exclusive to UA Audio Interfaces, Unison technology nails the
tone of these sought-after tube and solid state mic pres —

in Apollo Console software, and it physically reconfigures the Apollo
interface's impedance — so you can tap into the classic sounds of
the world’s most recorded mic preamps.
