Special options include:
• Auto Gain Control
Gain settings affect the overall 
 of the audio to make the audio sound more consistent by automatically 
adjusting the volume. Auto Gain Control is great for keeping sounds clear, without being too strong, even in 
noisy external environments. Settings include Off (the default setting), LowMedium, and High.
• Stereo Separation
Many albums recorded in stereo during the early days of studio production separated all instruments to one 
side and all vocals to another. This type of extreme stereo separation is found on many Beatles and Buddy 
Holly albums. The Stereo Separation option merges the left and right stereo channels together to 
compensate for stereo effects that may sound strange when played on headphones. Specific tracks can be 
marked using Rio Music Manager to use Stereo Separation compensation. Settings include Off (the default 
setting) and All tracks.
