RME Audio ADI-6432 /ADI-6432R

RMEs SteadyClock(TM) 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 every function has its own keys accompanied by clear function LEDs. Especially in a professional application, exact, quick and direct control and display 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.
