Soundcraft / Si Expression 3

The fader glow system changes the color inside the fader depending on the function, realizing an intuitive operation. The DSP developed jointly with STUDER achieves uncompromising sound quality.

* When the monaural input channel is expanded to 54 using the stage box, 2 stereo line inputs are counted as 4 channels, and 4FX returns (4 stereos) are counted as 8 channels, the sum of monaural input channels + stereo line inputs + FX returns value.

≪ Flexible bus settings ≫
6 monaural AUXs out of 14 monaural AUXs can be switched to 6 stereo AUXs. The output to the AUX bus can be switched between pre / post for each channel, allowing for flexible settings according to the application. The 4 monaural matrix can also be switched to the 4 stereo matrix.

≪ Assignment function to channel fader and highly flexible patch system ≫
Inputs, bus outputs, VCA and DMX outputs can be assigned to any channel fader (VCA and DMX are only available for Si Performer). As a result, frequently used functions can be combined into one fader layer, greatly improving operability. It also has a very flexible patch system that can send all input signals to any channel and all bus signals to any output terminal. By combining these two functions, you can freely control the signal.
