Description

The CARD-2MADI-SO from Digital Audio Denmark is a powerful expansion module designed to bring flexible MADI (Multichannel Audio Digital Interface) connectivity to your audio routing system. With two bidirectional MADI ports, this card supports both optical and electrical (coaxial) SFP modules, making it adaptable to a wide range of professional studio and broadcast environments. Whether you're connecting over single-mode or multimode fiber, or via coaxial cables with HD-BNC connectors, the CARD-2MADI-SO delivers robust performance and high channel counts.

Each MADI port on the card can independently handle up to 64 input and 64 output channels at 48kHz, with support for sample rates up to 384kHz. The card offers independent sample rate conversion (SRC) on both inputs and outputs, giving engineers more control over clocking and synchronization. It supports both legacy SMUX and high-speed frame modes, accommodates 56 or 64-channel formats, and can sync to either the incoming MADI signal or the internal system clock. This makes it an ideal solution for managing complex digital audio workflows where compatibility and clocking flexibility are critical.

Features

Dual MADI Ports
Includes two bidirectional MADI ports, each supporting 64 input and 64 output channels at standard sample rates.

Flexible Connectivity
Supports optical (LC) or coaxial (HD-BNC) SFP modules for easy integration with different MADI infrastructures.

Sample Rate Conversion
Built-in converters allow independent SRC on both input and output ports for seamless format matching.

Wide Sample Rate Support
Handles sample rates from 44.1 kHz up to 384 kHz, with reduced channel counts at higher rates.

Legacy & High-Speed Modes
Compatible with both SMUX legacy and high-speed frame formats for broad system compatibility.

Selectable Chanel Formats
Supports both 64- and 56-channel MADI configurations to match various studio setups.

Clock Sync Options
Can sync to incoming MADI signal or internal system clock for flexible integration.

Low Latency Operation
Delivers fast conversion performance, under 1.1 ms, even during sample rate changes.

Modular Expansion
SFP modules are sold separately, allowing you to tailor the card to your preferred connection type.
