Soundcraft Si Expression 2 Digital Mixer

Full Description

Brimming with convenient features

TOTEM™, ViSi Connect™, BSS® GEQ, D.O.G.S - there's an acronym for every audio need on board the Si Expression 2. The TOTEM™ system is 'The One Touch Easy Mix', this lets you use a single key to instantly reconfigure an AUX, FX, or Matrix bus at the push of a button.

BSS GEQ provides a graphic EQ processor for every single bus. There isn't a shared pool of processors so you'll never run out of EQ processing power on your buses. An integrated Direct Out Gain Stabiliser (DOGS) prevents manual alterations to mic gain affecting direct out levels. This is ideal if two mixers share a stagebox for example.

Lexicon® Digital Effects

Lexicon® studio-quality effects allow you to effortlessly achieve professional-quality sound without additional plug-ins or outboard equipment. Industry-standard signal processing technology within the DSP engine ensures reliable operation while reverb, chorus, delay effects with tap tempo, and many more allow you to enhance your performance. The mixer includes four stereo effects engines - the creative possibilities are astounding.

Instant access for easy usability

Included on the mixer are a set of easy access keys. These make navigating your live sound life easier than ever. Leave context menu diving behind, with easy store, recall, mute, selection, and tap tempo buttons. Copy and paste keys also mean you can copy the settings from an entire channel, bus, mix, or effects processor.
