What is the relationship between mixing channels and the number of channels?
We are used to call a mixing console with xxx channels of inputs a "xxx-channel" console, such as the Soundcraft GB4 32, commonly known as the 32-channel console. A analog console has 32 input channels with each corresponding to its own connector and fader due to its circuit design. But this doesn't apply to a digital console, as the corresponding relations among connectors, faders and mixing channels are disrupted.
The number of channels that an analog console has can be compared to that of lanes on the ground. So if you want more cars on the ground, add more lanes. But for digital consoles, it's like having elevated highways that offer lanes up and down and at the same time save more ground resources. So we shouldn't get ourselves confused by the"old habits", because the number of channels here doesn't mean the real input channels of a console, much less its actual mixing channels!



So what determines the capacity of a console?
Mixing channels are the sum of the input channels that a console can process, which can be broken down into local mic/line input channels, stereo/effector return channels, and digital audio channels. But how can these channels be distributed and used? We'll take a Soundcraft Si Impact digital console with 80 channels to mix as an example to answer the question:

1.Combine the 32 mic inputs on the Si Impact console plus 32 USB inputs for 64 total channels to mix.

2.Add one Soundcraft Mini Stagebox 32 or 16, plus the 32 mic inputs on the Si Impact console, to get up to 64 mic channels to mix.

3.Add the Dante option card to get 64 Dante channels to mix.

So as you can see, it's the the number of channels to mix rather than that of physical connectors that determines the maximum working capacity of a digital console. For a Soundcraft Si Impact digital console with up to 80 channels to mix and just 32 mic inputs, but with dual card slots and 32x32 USB audio interface can help it have the power that a digital console with 80 mixing channels can deliver. 


But why do we need so many channels to mix?
When we're using a Soundcraft Si Impact digital console for live sound reinforcement, a lot of cable connections can be done in the stage area with two MADI-based stageboxes placed on the two sides of the stage, offering 64 audio inputs, enough to meet the different demands of gigs (12 mics required), programme hosting (2-3 mics required), choruses (3-5 mics required), and symphony orchestra performances (10-30 mics required). It can also distribute stereo audio and USB multi-track recording and playback signals to 14 mono mixing buses, 6 stereo buses, 4 stereo matrix buses, 4 dedicated effector sending buses, and L/R mono main output.
With a Soundcraft Si Impact digital console, you can accomplish multiple tasks of a live performance from live sound reinforcement to recording collection. It is only possible with its great numbers of channels to mix and over 40 years of live mixing experience.
