Product details

The SPL Audio Madison is a professional 16-channel analog-to-digital and digital-to-analog converter designed to connect analog studio equipment with MADI-equipped digital consoles, audio routers, and recording systems. Combining 16 analog inputs and 16 analog outputs in a compact 1U rackmount chassis, it delivers high-quality multichannel conversion at resolutions up to 24-bit/192 kHz. With optical MADI connectivity, word-clock synchronization, selectable reference levels, and expandable multichannel operation, the Madison is an effective solution for recording studios, broadcast facilities, scoring stages, and complex analog-to-digital workflows.

Key Features

16-Channel A/D Conversion: Converts 16 balanced analog input channels into digital MADI signals for recording, routing, and further processing.
16-Channel D/A Conversion: Converts incoming MADI audio into 16 balanced analog output channels for external processing equipment, consoles, and monitoring systems.
24-Bit Resolution: Supports high-resolution digital audio conversion for professional recording and production environments.
Sample Rates up to 192 kHz: Supports 44.1, 48, 88.2, 96, 176.4, and 192 kHz sample rates.
Optical MADI Connectivity: Features optical MADI input and output with SC connectors for multichannel digital audio transmission over fiber.
56- and 64-Channel Modes: Supports standard MADI channel configurations, with channel capacity depending on sample rate and operating mode.
Expandable Multichannel System: Up to four Madison units can be chained through MADI to provide as many as 64 analog inputs and 64 analog outputs at compatible sample rates.
Flexible Clock Synchronization: Can synchronize to its internal clock, an external word-clock signal, or the incoming MADI stream.
Selectable Reference Levels: Offers four reference-level settings—+15, +18, +22, and +24 dBu—to match different analog equipment and digital full-scale levels.
Varispeed Support: Supports variable-speed operation for specialized recording and synchronization workflows, with the permitted range depending on the selected MADI mode.
Balanced Analog Connectivity: Uses two DB25 connectors for eight-channel analog inputs and two DB25 connectors for eight-channel analog outputs, following the Tascam pinout standard.
Channel-Level Displays: Front-panel level indicators provide clear visual feedback for groups of input and output channels.
Silent, Fanless Operation: Its fanless design is suitable for quiet recording rooms, mastering suites, and other noise-sensitive environments.
Optional Redundant Power Supply: Can be configured with an optional second power supply for improved operational resilience.
Compact Rackmount Design: Fits into a standard 19-inch, 1U rack, conserving valuable studio space.
