The composite gain value is morphed to avoid pops.<\/span><\/p>\n<p><span style=\"font-family: 'times new roman', times, serif;\">Channel configuration (assignment to speaker types of the selected speaker groups), morphing time, and the gain level of each step are configurable through xTP interface. Basically, we are mixing run-time tuning (add cfg params) and design-time tuning (add cfg params). GTT is used for configuration in general, and xTP is the protocol used to deliver tuning data.<\/span><\/p>\n<p class=\"note\"><span style=\"font-family: 'times new roman', times, serif;\">Fader and Balance positions are provided through control inputs.<\/span><\/p>\n<p><span style=\"font-family: 'times new roman', times, serif;\">Fader Balance is ported from the Summit version with the following differences:<\/span><\/p>\n<ul>\n<li><span style=\"font-family: 'times new roman', times, serif;\">The option for 4 modes is not supported.

The number of control inputs is brought down to 2 due to this change.<\/span><\/li>\n<li><span style=\"font-family: 'times new roman', times, serif;\">Stand-alone Fader AO and Balance AO can be achieved by configuring the additional parameters in the SFD.<\/span><\/li>\n<li><span style=\"font-family: 'times new roman', times, serif;\">The step count is made as an additional variable instead of using the \u201cNumber of Elements\u201d field.<\/span><\/li>\n<li><span style=\"font-family: 'times new roman', times, serif;\">The channel configuration is done using a drop-down menu to select only one speaker type in each speaker group.
