RME's SteadyClock™ lets the ADI-6432 use MADI without an additional word clock connection, and guarantees excellent clock quality in every situation. Due to the highly efficient jitter reduction, any clock signal - even AES and word clock - can be improved and refreshed, and subsequently be used as reference clock at the word clock output. Intelligent Clock Control (ICC) will retain the last valid sample frequency in case of a loss of the input signal.

The ADI-6432 supplies word clock in Single, Double und Quad Speed, distributes Double Wire 96 kHz signals into the MADI data stream, and even supports the double MADI sample rate (96K frame). The SyncAlign® and SyncCheck® technologies known from other RME products ensure perfect synchronization and clear detection of errors. Also multiple units can be stacked and operated sample-aligned, using word clock. All settings are stored when the unit is switched off.

A fully automatic input selection between optical and coaxial input offers a useful redundancy mode for critical applications. Extensive status displays give information about lock and sync states, audio content and the physical quality of the incoming signal.

The front panel features an exciting and detailed Sync and Audio State display with 97 LEDs. Furthermore there are lots of buttons with clear LED function display. Especially in a professional application, exact display and control of all incoming and outgoing signals, including MIDI and RS232, becomes indispensable. Errors can be detected at a glance. The control keys can be locked to prevent accidental changing of settings.

SERIAL / MIDI EXTENDER
16 MIDI channels can be transferred invisibly across MADI, at the full count of 64 audio channels. The same applies to RS232: Be it 9600, 19200 or 115200 Baud, thanks to a 9-pin COM port, the ADI-6432 can be used as an extender for serial cables, with no effect on the audio functionality.

Additionally the device can be fully remote controlled and configured via MIDI, and all status displays can be queried through MIDI. Each ADI-642 can be given a separate ID, allowing separate remote controllability of various devices with only one MIDI channel.

The ADI-6432 is compatible to MADI interfaces of companies like Sony, Merging, Lawo, Euphonix, Stagetec, Jünger, Audio Service, AMS and others.
