The DiGiCo Quantum 338 is a top-tier, seventh-generation FPGA digital mixing console designed for high-profile touring, theatre, and large-scale live sound applications. It bridges the gap between massive flagship systems and more compact footprints by offering incredible routing versatility, pristine 32-bit conversion, and deep internal effects processing.

• Mixing Capacity: 128 input channels, 64 Aux/Sub-group busses, and a 24 x 24 full-processing matrix.
• Physical Control: 38 touch-sensitive motorized faders laid out across three distinct banks.
• Displays: Three 17-inch high-brightness LCD touchscreen displays provide dedicated visual real estate for each section.
• Audio Processing: Operates natively at 48kHz or 96kHz sample rates with an internal 40-bit floating-point processing structure.
• The Pulse Upgrade: Owners can opt for the Quantum 338 Pulse software expansion, which supercharges the internal architecture to support 156 input channels and 72 Aux/Sub-groups.

The Pulse Software Upgrade

The Quantum 338 Pulse expansion unlocks significantly more DSP horsepower directly from the internal FPGA engine:

Channels & Busses: Bumps your mixing capability from 128 to 156 input channels, and from 64 to 72 Aux/Sub-group busses.

Mustard Processing: Increases dedicated Mustard channel strips from 36 to 48 channels.

Nodal Processing: Expands from 64 to 72 Nodal processors, giving you massive flexibility for customized monitor mixes.

Mix Minus: Seamlessly injects Mix Minus functionality directly into the workflow architecture.

The DiGiCo SD-Rack 32-bit 56/48 is a premium, tour-grade modular stage box configured specifically with 56 inputs and 48 outputs utilizing DiGiCo’s industry-leading 32-bit conversion technology

Because the physical master frame of an SD-Rack contains exactly 14 card slots (each accommodating 4 channels), a standard 56-input setup fully populates 14 slots (14 slots × 4 channels = 56 inputs). To achieve the 48-output side of this specific configuration, the rack is usually built out as a hybrid layout—for example, carrying 56 32-bit analogue inputs, 48 32-bit analogue line outputs, and 8 digital outputs (such as AES/EBU) to utilize the internal routing limits of its dual MADI or optical streaming paths.

Key Specifications & Capabilities

• 32-Bit Sonic Clarity: Outfitted with DiGiCo’s ultimate 32-Bit Mic Pre-Amp and 32-Bit DAC cards, providing unprecedented dynamic range, ultra-low noise floors, and pristine analog-to-digital translation.
• High-Resolution Sample Rates: It is 192kHz high-resolution ready and natively supports down-sampled splits (like running an optical loop at 96kHz with a 48kHz down-sampled feed for broadcast trucks).
• Flexible I/O Connectivity: Connects effortlessly via high-performance HMA Optics (Optocore fiber) or direct dual redundant MADI ports.
• Full Channel Redundancy: Provides a full 56 channels of redundant digital audio transport at both 48kHz and 96kHz sample rates.
• Gain Tracking™ Technology: Allows multiple consoles on a shared optical loop to receive the same inputs seamlessly. If one console adjusts the analog pre-amp gain, DiGiCo’s internal Stealth FPGA processing applies automatic digital gain tracking (±40dB) to protect everyone else’s independent mixes from clipping.
