RME DMC-842

When developing the DMC-842, RME worked closely with the microphone manufacturers to secure maximum compatibility and best functionality. As a result the DMC-842 is the most flexible and most compatible AES42 interface available - a true milestone for the broad acceptance of the new digital microphone technology.

The DMC-842 is fully remote controllable, via MIDI, AES and (optional) MADI. The optional I64 MADI Card provides serial pass-through capability from one DMC-842 to the next (up to 8). All up to 64 audio signals are then available at the last device on one single line. Such a way of cascading is also possible with the Micstasy and the ADI-8 QS. The signals passed through the DMC-842 are available at the analog outputs, making an expensive splitter box on stage obsolete.

Overview of the DMC-842's most important features:

• Fully compatible to AES42
• 8 XLR AES42 inputs (AES3 compatible)
• 8 balanced XLR Line outputs
• 24 bit sample rate conversion switchable per input
• Digital Phantom Power switchable per input
• Supports Mode 1 and Mode 2
• 63 dB gain range per channel, even in asynchronous Mode 1
• LED level meter with 13 LEDs per channel
• M/S de-/encoding
• 4 x AES/EBU Out via D-sub, 8 channels @ 192 kHz
• 2 x ADAT Out, 8 channels @ 96 kHz
• Optional MADI I/O (I64 MADI Card) with serial cascading and digital/analog return path
• MIDI I/O
• Fully remote controllable
• Future-proof by flash updates

Features:

In a standard 19" box with 2 unit height the device offers numerous extraordinary features like Intelligent Clock Control (ICC) Intelligent Clock Control (ICC)
Our unique SyncCheck and AutoSync technology has evolved into the new Intelligent Clock Control of the Hammerfall DSP system. HDSP is the only digital I/O-system worldwide capable of measuring and displaying the frequency of all clock sources. Even word clock! Based on validity and current sample rate the system then decides which clock source should be used - fully automated and performed in hardware! With this the HDSP system offers the most easiest handling of the present clocks, although having a lot digital inputs, plus the most advanced support when configuring the clock setup. , SyncCheck SyncCheck
When working with several digital sources it is not only necessary that these are all properly locked, they also have to be totally synchronized. Else drop outs and crackling occurs.
RME's exclusive SyncCheck checks all input signals. In clock mode Master the synchronous operation to the internal clock is checked. This outstanding and unique technology helps to find errors immediately. The actual state of each input is displayed in the settings dialog. ®, SteadyClock, MultiMode, MIDI over MADI, and remote control via MADI and MIDI.

The technologies known from other RME products like SyncCheck® 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.

The DMC-842 can be fully remote controlled and configured via MIDI, and all status displays can be queried through MIDI. Each DMC-842 can be given a separate ID, allowing separate remote controllability of various devices with only one MIDI channel.

RME's SteadyClock^(TM) guarantees excellent clock quality in any situation. Due to the highly efficient jitter reduction, the DMC-842's DA-converters operate independently from the quality of the external clock signal, as if they are working with internal clock all the time - guaranteeing a pristine sound quality! Additionally Intelligent Clock Control (ICC) will retain the last valid sample frequency in case of a loss of the input signal.
