Digital, balanced, and unbalanced version (G68AXD)
The G68 hardware architecture is designed to process up to 12
completely independent output channels. Currently the software
limits the number of outputs to a total of eight: Main L/R, Centre,
Sub, Rears, and either Sides or two more additional subwoofers.
All versions of the G68 provide analogue and/or digital output
sockets for these eight speakers. The G68AXD, G68XXD, G68ADV,
and G68AXV provide an additional digital stereo output (A/B)
which may currently be used for a pair of subwoofers. Future
software updates will allow these outputs to be used in addition to
side speakers for either extra subwoofers or height channels.
The G68AXD, G68XXD, and G68ADV feature a pair of analogue
outputs, LZ/RZ, which can be used for any pair of outputs such
as an analogue subwoofer or a pair of analogue rear speakers.
In conjunction with the other outputs this will in the future allow
these products to drive up to 12 independent outputs.
