THE Hi-End MADI / AES Frontend!
RME expands its successful MADI series with the ADI-642, an
8-channel format converter from MADI to AES and vice versa. Amongst other
applications, the unit can serve as ideal AES/EBU frontend for the Hammerfall
DSP MADI PCI card. Up to 192 kHz at 24 bit are supported. Its most outstanding
feature is an easy-to-use 72x72 routing matrix, which can assign an individual
input channel to every single output channel, allowing free configuration of all
64 MADI channels and the 8 AES channels.
Additional features include:
- Native support for AES Double and Quad Wire
- Native support for MADI Double and Quad Wire
- Direct conversion between these formats
- Automatic Delay Compensation when using more than one unit
- Analog stereo monitor output, up to 192 kHz
- Detailed status display for MADI and AES
- Completely remote controlable via MIDI
- Transfer of MIDI data via MADI
- SteadyClock for maximum jitter reduction and clock regeneration
The compact unit with 19" width and 1 unit height serves as
format converter MADI to/from AES. MADI handles 64 channels of 24 bit audio at
sampling frequencies up to 48kHz, 32 channels up to 96kHz, and 16 channels up to
192kHz. All channels are transferred across a single cable, either coaxial (BNC)
or optical network cable. In both cases, cable lengths of more than 100 meters
can be achieved. The AES/EBU channels are provided via 4 XLR inputs and outputs,
respectively. The ADI-642 accepts 56 channels and 64 channels as well as 96k and
192k frame at its input, and can be set to generate those formats at its output.
This way the ADI-642 even serves as perfect interface between otherwise
incompatible MADI devices.
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 ADI-642 is compatible to all forms of increasing the sample
rate. It supplies word clock in Single, Double und Quad Speed, distributes
Double Wire 96kHz signals into the MADI data stream and to the AES ports, and
even supports the double MADI sample rate (96K frame). The same applies to 192
kHz (Quad Wire, 192 kHz frame).
The ADI-642 features an easy-to-use 72 x 72 Matrix Router. An
input signal can be assigned to every output channel, both for AES and MADI.
This not only allows free signal routing during format conversion, but also
forwarding and routing of signals within the same format. An input signal can
also be distributed to any number of outputs. With more than one ADI-642,
several MADI signals can be combined (merged) to one MADI stream.
16 MIDI channels can be transferred across MADI (even with 64
audio channels). 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.
RME's SteadyClock (TM) guarantees excellent clock quality in
every situation. Due to the highly efficient jitter reduction, any clock signal
can be improved and refreshed, and subsequently be used as reference clock at
the word clock output. The last valid sample frequency will be retained in case
of a loss of the input signal.
Automatic Delay Compensation eliminates technically inherent
delays when signals are transferred from one unit to another. Each device
automatically recognizes its position within the chain and ensures sample
synchronized operation of all AES inputs and outputs.
The analog monitor output operates in stereo and has a low
impedance. It can be used as line and headphone output and supports 192 kHz at
119 dBA SNR. The routing matrix can assign any of the 36 stereo input pairs to
the monitor output.
The ADI-642 is compatible to MADI interfaces of companies like
Sony, Merging, Lawo, Euphonix, Stagetec, J�nger, Audio Service, AMS and
