MADI.9648 is a synchronous MADI sample rate converter with four independent SRC blocks for bidirectional conversion of 128 audio channels. Equipped with eight MADI ports it features synchronous low latency conversion in a ratio of exactly 1:2 or 2:1 to translate between 2 FS (88.2/96 kHz) and 1 FS (44.1/48 kHz).
A 1 FS MADI stream with 64 audio channels is converted into two 2 FS MADI streams with 32 channels each. Vice versa two 2 FS streams are converted and combined into a single 1 FS stream.
This enables an easy-to-handle integration of external equipment with most recent live consoles with 96 kHz processing.


There is nothing to adjust – a fixed signal routing and automatic signal detection of frame format (48k/96k Frame) and channel mode (56/64 ch) facilitate the installation. The 2 FS inputs accept both 96k Frame and 48k Frame (S/MUX). The 2 FS outputs are set to 96k frame or 48k frame (S/MUX) following the input of the same port.


There is no common clock source needed. The output of each SRC block is clocked by it’s corresponding MADI input.


Low latency processing of eight samples round-trip (1FS-2FS-1FS) meets the demanding requirements of live sound applications.


MADI.9648 features six BNC ports which are mostly deployed in live consoles. Two optical SC ports extend the connection scenario for 1 FS signals.
An integral USB port enables firmware updates for future enhancements.


The device is equipped with two phase-redundant power supplies to ensure maximum reliability.
