Multi-channel audio, typically embedded in an SDI signal, can be passed through
the FS-HDR converter unchanged. The multi-channel sound can also be mixed
down to stereo, using the two Mix Down Modules built into the FSI-X Audio
Processor.
The default 5.1 to 2 ch. mix-down equation is:
• Left Ch Output = LF + (-3dB * CTR) + (-3dB * LR)
• Right Ch Output = RF + (-3dB * CTR) + (-3dB * RR)
The default 7.1 to 2 ch. mix-down equation is:
• Left Ch Output = LF + (-3dB * CTR) + (-3dB * LS) + (-3dB * LR)
• Right Ch Output = RF + (-3dB * CTR) + (-3dB * RS) + (-3dB * RR)
These default settings can be adjusted using the front panel menus or web
interface.
NOTE: The LFE channel is not used in the stereo mix down output, but is passed through
the FS-HDR audio routing matrix.
3.16 - 3.17 Mix Down Output Lft Rt Level
The level of the Left and Right mixer output signal can be adjusted plus or minus
18 dB, in half dB increments, using these menu controls. Default is 0 dB (unity).
3.0 Mix Down 2 Mode
(4Ch only) Same as Mix Down 1 Mode menu and related sub-menus, except for
the Mix Down 2 mixer.
