6.1 and 7.1 formats
IMAX uses a 6.1 system, adding a top channel to the 5.1 standard.
This configuration was supported by the original Holophone H-1
(now discontinued). It is currently supported by the H2-PRO.
Dolby, DTS and SRS Labs (among others) introduced extended
surround formats that use a 6.1 configuration. These are Dolby
Digital EX, DTS ES (Extended Surround) and Circle Surround II
(CS II). However, instead of a top channel, these standards add a
center rear channel.
Sony has introduced a standard, SDDS (Sony Dynamic Digital
Sound), which has a 7.1 configuration. However, it does not use
either the rear channel or the top channel. Instead, it adds a left
center and a right center channel.
All 6.1 and 7.1 formats are supported by the Holophone H2-PRO.
