Unison Technology: The Genuine Sound of Neve, API & Manley Preamps
Apollo x4 features four 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 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.
*Includes the "Realtime Analog Classics" UAD plug-in bundle. Other UAD plug-ins sold separately.
