Allen & Heath M-SQ-MADI-A SQ MADI 64x64 96/48kHz Option Card for SQ & AHM

Allen & Heath M-SQ-MADI-A: 64x64 MADI for SQ and AHM

The Allen & Heath M-SQ-MADI-A is a MADI option card that adds a 64 x 64 channel interface at 48 or 96 kHz to SQ mixers and AHM audio matrix processors. It provides two BNC inputs and two BNC outputs for split or redundant setups, plus a dual-function word clock BNC that can act as clock master or slave. Both S/MUX and HighSpeed 96 kHz transport modes are supported, so it can match whatever MADI device sits at the other end. Because MADI is the open AES10 standard, the card connects an SQ or AHM system to broadcast rigs, recorders, OB vans, and third-party consoles. For high-channel-count interconnect on the SQ platform, it is the direct MADI route.

How MADI Serves the SQ and AHM Platforms

MADI (AES10) streams up to 64 channels of digital audio over a single 75-ohm coaxial link, making it a compact way to move a full stage's worth of signal between systems. On this card, two BNC in and two BNC out let you run a split, sending SQ inputs to a recorder or second console, or a redundant pair for a hot backup link. To reach 96 kHz, MADI uses either S/MUX, which multiplexes channel pairs, or a HighSpeed mode, and the card supports both for compatibility. The dual-function word clock BNC keeps the SQ or AHM locked to, or providing, a house clock so multiple digital devices stay sample-accurate. This is standard, dependable MADI engineering applied to Allen & Heath's install and live processors.

Splits, Recording, and Broadcast Feeds

The most common use is a digital split: all of an SQ's channels streamed over MADI to a broadcast truck, a multitrack recorder, or a monitor console with no analog splitter box. For AHM installs, MADI provides a clean interconnect to third-party matrix systems or DSP in a larger facility. Redundant mode protects critical feeds by mirroring the stream onto the second port. Because the card carries 64 channels each way, an entire SQ mix or a large AHM zone map can cross to another system on one pair of cables. Note that the card requires SQ firmware V1.5.2 or later to operate. For any workflow that must interface with the broader MADI world, this card is the bridge.

Who the M-SQ-MADI-A Is For

This card is for SQ and AHM owners who need to interface with broadcast, recording, or third-party MADI systems, or to build redundant MADI links for live work. It suits houses of worship, theaters, and broadcast facilities that already run MADI infrastructure. It is host-powered, fits the SQ/AHM option slot, and requires SQ firmware V1.5.2 or later. Compared with the SQ Dante or SQ Waves cards, it is the choice specifically when MADI interoperability is required. For SQ-to-MADI integration, the M-SQ-MADI-A is the answer.
