Mix-Minus Combiners are provided to enhance the capabilities of Auto Mixers in mix-minus and input expansion applications. Mix-Minus Combiners combine control data only and, therefore, have no audio outputs. Inputs to a Mix-Minus Combiner come from outputs of separate Auto Mixers. Ch / Combine allows input channels (1, 2, 3 etc.) to be grouped into specific combinations (A, B, C, etc.). These combinations automatically determine proper routing of control data for the Auto Mixers. Control data represents NOM (number of open mics) and ATS (adaptive threshold sensing) information. Mix-Minus Combiners are used when the Auto Mixer outputs are also connected to a separate Matrix Mixer (to create multiple 'mix-minus' outputs). Also, Mix-Minus Combiners allow large Auto Mixers to be created from multiple, smaller ones. This is useful when more than 32 inputs are required, or when an Auto Mixer must be placed into multiple Audia units (for proper DSP allocation or for physical location of inputs).
