Special options include:
• Auto Gain Control
Gain settings affect the overall Gain 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), Low, Medium, 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.
