Audio outputs

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 G68D, G68AXV, and G68ADV provide an additional 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 G68ADV and G68D feature a pair of analogue outputs, LZ/RZ, which can be used for any pair of outputs. For example on the G68D a Meridian Digital Theatre may be complemented with

an analogue subwoofer or a pair of analogue rear speakers. In conjunction with the other outputs this will in the future allow the G68ADV and G68D to drive up to 12 independent outputs.
