The Apollo Twin MkII Quad Captures the Sound of Legendary Preamps with Unison Technology

The Apollo Twin MkII's Unison preamp technology goes so far beyond traditional software modeling and emulations that it's really in a category all its own. In essence, Unison is a bi-directional communication between the Apollo Twin's mic preamp and a Unison-capable plug-in, such as the included 610-B plug-in that re-creates the sound of Universal Audio's classic 610 tube preamp.

The plug-in actually adjusts the preamp circuit itself, including parameters such as impedance, analog gain structure, and much more. When you adjust the Apollo Twin MkII's preamp gain knob and physical controls, the plug-in adjusts the preamp's behavior to match the target preamp. So you're not simply filtering your audio to approximate the character of a famous preamp — your microphone is now interacting with the Apollo Twin MkII's input the same way it would behave with the "modeled" preamplifier.

UAD plug-ins astounded the recording world with their incredible ability to sound like analog processors, eliminating the need for large racks of gear in the studio. The Apollo Twin Quad’s Unison preamp technology will do the same thing for your microphone inputs, eliminating the need to collect and maintain expensive hardware preamps just for sonic variety.
