DiGiCo has expanded its Quantum Range with the Quantum638 mixing console and optional Quantum638T version for theatrical productions. Combining elements of the SD7 and SD5 with the latest Quantum technology, the console provides enhanced access to cue firing and Macros for musicals, plays, tours and installations requiring fast, redundant and compact control.

Positioned between the Quantum852 and Quantum338 Pulse, the Quantum638 offers 256 input channels, 128 aux/sub-group buses and a 48×48 matrix. Processing includes 128 Nodal Processing instances, 64 Mustard Processing strips and 16 Spice Rack slots. Onboard Dante and a built-in Fourier Interface Card provide native compatibility with Fourier Audio’s transform.engine.

The worksurface features three 17-inch high-resolution touchscreens above 38 100mm touch-sensitive motorised faders, with additional displays for metering and channel information. Four channel Macros follow the selected channel across console layouts, while assignable Macroder rotary encoders control programmable parameters for the active channel. A new InfoBar keeps snapshots, timecode and system warnings continuously visible.

The Quantum638 is DiGiCo’s first Quantum console available in both single- and double-engine configurations, with the dual-engine version also capable of operating in single-engine mode.

The optional Quantum638T theatre software extension adds Auto Update, Aliases, Players, advanced CG programming tools and Matrix Nodal Delays. With a footprint close to the SD7, the console offers theatres increased processing capability without significantly expanding the worksurface.

Both engine configurations feature dual DMI card slots and hot-swappable power supply units. Each engine also incorporates a MultiMode Optocore interface supporting 504 additional audio paths at 48kHz and 96kHz. An optional second Optocore loop can double this capacity.
