FS1-X v1.1 www.aja.com 86
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 FS1-X
audio routing matrix.
28.1 Mix Down 1 Input When 5.1 Channel or 7.1 Channel is selected above, this parameter selects the source of
the multi-channel audio coming into that mixer.
28.2 - 28-8 Mix Down 1
Input Mapping (LF, RF,
CTR, LR, RR, LS, RS)
When Map is selected above, these menus permit the mapping of any FS1-X audio input
channel or signal generator to any of the mixer inputs (L Front, R Front, Center, L Rear,
R Rear, and in 7.1 mode L Surround and R Surround). Each mixer input can also be turned
Off (muted). Default setting is Off.
28.9 - 28.14 Mix Down 1
Input Level
In Mix Down Mode, multi-channel input channels are mixed to the Left and Right output
channels. The level of each input signal sent to its mixed output can adjusted plus or
minus 18 dB, in half dB increments, using these menu controls.
The default settings are set to the basic equations above, and are listed below.
NOTE: The LFE channel is not used in the stereo mix down output, but is passed through the FS1-X
audio routing matrix.
28.16 - 28.17 Mix Down
1 Output Lft Rt Level
The level of the Left and Right mixer output signal can adjusted plus or minus 18 dB, in
half dB increments, using these menu controls. Default is 0 dB (unity).
