1. User Guide
Whereas Dirac Live 2 introduced the next generation of the Dirac Live Room Correction technology,
Dirac Live 3.0 builds on this and introduces the new Dirac Bass Control technology for compliant de-
vices.
Dirac Live Bass Control is technology to manage low-frequency channel routing from the signal to
the playback channels (speakers) of your audio device. Additionally, with full control over the device’s
channel and frequency routing and output, the Dirac Live room correction technology is signicantly
augmented. In particular systems with multiple subwoofers will see substantially improved room
correction and bass performance.
This section presents the Bass Control user-guide and the required equipment in order to do the
calibration.
Key terms:
} Dirac Live: The Dirac technology to process audio to correct an audio device’s output for the
acoustics of the listening environment. Also the name of the application providing this technology.
} Dirac Live Bass Control: The Dirac technology to enable all speakers to act in support of each oth-
er by routing bass-frequency audio from an input source to output channels. This name covers
two aspects, bass management and bass control:
{ Bass management: routing and mixing of source audio optimally between output channels.
{ Bass control: calculating inter-speaker support to enable room correction beyond the capa-
bility of individual speakers.
