Unison Technology: The Genuine Sound of Neve, API & Manley Preamps
Apollo Twin X features two Unison-enabled mic preamps, letting you track through 
exacting mic preamp emulations from Neve, SSL, API, Manley, and Universal Audio. An 
Apollo exclusive, Unison technology nails the tone of these sought-after tube and solid 
state mic pres — including their input impedance, gain stage “sweet spots,” and the 
component-level circuit behaviors of the original hardware.
The secret to Unison is its hardware-software integration between Apollo’s mic 
preamps and its onboard UAD-2 QUAD or DUO Core DSP Acceleration. Simply place a 
Unison preamp plug-in on your mic input 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.
