Questions frequently asked
Soundcraft Si Expression 2: how many mic inputs and faders?
The listed console has 16 faders and 24 mic inputs.
Can monitor mixes be controlled directly from the faders?
The TOTEM function assigns the faders to mix inputs to the selected bus. Monitor mixes can thus be adjusted without needing multiple control pages.
Which effects are built into the console?
Four Lexicon effects processors are integrated for reverbs, delays, or modulations. Four dedicated stereo returns are also available.
What expansion card can be used with this console?
The 64 x 64 expansion slot allows adaptation of the console to a multitrack recorder, stage rack, or audio distribution. Supported formats depending on the card include MADI, Blu-Link, CobraNet, RockNet, Aviom, AES/EBU, and MultiDigital. Remote control is possible with ViSi Remote on iPad.
What is the purpose of D.O.G.S on the Si Expression?
The D.O.G.S process stabilizes the level of sends and direct outputs when the input gain is changed. This function is especially useful for sources shared between several consoles.
