How many signals can I sum using Sigma?
Sigma has 16 stereo inputs, which can be assigned to two stereo buses: Mix A and Mix B.
Inputs can be configured as either mono or stereo paths. Where a stereo channel is sent to a Mix bus, the left input will be routed to the left channel of the Mix bus, and the right input will be routed to the right channel of the Mix bus.
Where a mono channel is routed to a Mix bus, the left input of the channel is sent to both left and right channels of the Mix bus, controlled by a pan control in the Sigma browser. The channel’s input meter will display signal on the left meter only, and the right input to the channel will be disconnected. To configure a channel in this mode, select the channel in the Sigma Browser and select the “Mono” button.
