SPL SPLMAD overview

  • 1Description

The Madison MADI Interface from SPL is a 16-input/16-output MADI interface. It offers SPL analog sound for every MADI-equipped digital console, router, and PC MADI card.

With 16 input and 16 output channels in a single rack space, the Madison combines signal conversion with reliable clock and MADI processing. And as a true SPL unit it is designed to be simple to operate, easy to expand and, of course, a very good sounding conversion system.

Thanks to its I/O equipment, the Madison makes it simpler to integrate professional analog gear into larger multi-channel infrastructures. With four popular reference levels, operational sample rates between 44.1 and 192 kHz, multicore analog I/O, fibre MADI I/O and word clock I/O, the Madison simply fits just about everywhere.

Up to four units can be connected to a single MADI port on a digital console, a MADI PC card, or any professional audio-routing infrastructure. The MADI port offers near-zero-latency digital transmission of up to 64 I/Os with galvanic insulation. And since MADI is the emerging new studio I/O standard, the Madison is a suitable interface for home and project studios, commercial recording studios, and scoring stages.

Broadcast and live professionals have relied on the still-unsurpassed MADI for about 20 years now - with jitter-free, rock-solid transmission of many audio channels per single wire, and low-cost cabling with lengths far above one mile, MADI simply offers unique advantages.
As SPL focuses on analog, and competent converter technology requires an appropriate analog background, that is where a true difference can be made. The company has designed an analog audio section on 36V audio rails, reaching output levels of 24 dBu. With its straight-forward operation and flexible expansion, the Madison is an ideal interface for anyone interested in the advantages of the MADI format.
