Page 6: Introduction
The unique Intelligent Clock Control (ICC) allows for a flexible use with internal clock (44.1 up to 192 kHz), external word clock or the digital input signals. These options are intelligently coupled in a way typical for RME, and easy to apply thanks to a clear and easily understandable display of the Lock and Sync states. -

Speed. The big LED display, AES INPUT STATE, shows the presence of a valid input signal separately for each AES input. RME's exclusive SyncCheck indicates via flashing LEDs if one of these inputs is locked, but not synchronous to the chosen clock reference. - Page 8 The rear of the ADI-6432R BNC provides the following connections: 64 BNC connectors (AES- 3id I/O), two MADI optical, two MADI coaxial (BNC), two word clock (BNC), two MIDI (5-pin DIN), one RS232 (D-Sub), and two mains power. MADI I/O optical: Standard MADI ports.

The AUDIO LEDs light up as soon as the digital signal carries information other than digital zero. The channel doesn't matter. So there is only one channel of audio information necessary for the LED to light up. The amount of level is not indicated. User's Guide ADI-6432R BNC © RME... -

Page 18: Word Clock
As soon as a valid signal is detected, the WCK LED is constantly lit, otherwise it is flashing. Thanks to RME's Signal Adaptation Circuit, the word clock input still works correctly even with heavily mis-shaped, dc-prone, too small or overshoot-prone signals. Thanks to automatic signal centering, 300 mV (0.3V) input level are sufficient in principle. -
Page 19: Technical Description And Background
22 MHz from a slow word clock of 44.1 kHz is no problem anymore. Additionally, jitter on the input signal is highly rejected, so that even in real world usage the re-gained clock signal is of highest quality. User's Guide ADI-6432R BNC © RME... -

Page 21: Midi And Rs232
Technically every single MADI channel includes several additional bits, containing various in- formation (Channel Status). RME use the usually unused User Bit of channel 56 (channel 28 in 96k frame mode), to transmit MIDI data invisibly within MADI, ensuring full compatibility. -
Page 22: Remote Control Software
12.3 Remote Control Software A free remote software for Windows and Mac OS X can be downloaded from the RME website. It can use any existing MIDI port within the system to perform remote control and status re- quests of any number of supported RME units via a simple mouse click. Most appealing is the combination with a HDSP(e) MADI, offering a direct control of the ADI-6432 via MADI. -

Page 24: Application Examples
68 µs. 13.2 Digital AES-3id Breakout Box As MADI from/to AES/EBU converter the ADI-6432 is an ideal breakout box for RME's HDSP MADI PCI card. The application breakout box/computer unveils a delay, the so called offset between playback and recording. If a signal is played back from the MADI PCI, and recorded again via MADI by performing an AES loopback, the record track will show a specific delay against the playback track. - Page 25 User's Guide ADI-6432R BNC © RME...

MADI data stream. Example: A mixing desk sends 48 channels via MADI. 16 more channels from two RME Oc- taMic-D (8-channel microphone preamp with AES outputs) shall be recorded by a HDSP MADI into a computer. - Page 27 MADI input signal directly to the MADI output. At the same time, the unit fills the unused MADI channels at its MADI output with the audio signals from the AES inputs. The diagram shows cabling and signal flow of such an application.

The Quad Wire method allows to transmit two channels at up to 192 kHz via ADAT. The method is referred to as S/MUX4. Note: All conversions of the described methods are lossless. The existing samples are just spread or re-united between the channels. User's Guide ADI-6432R BNC © RME... -

PLLs and data buffers. Therefore a random error of ± 1 sample differ- ence between the stereo pairs can occur. The ADI-6432's exclusive SyncAlign technology avoids this effect and guarantees sample synchronicity among all four stereo channels. User's Guide ADI-6432R BNC © RME... -

2 km. Single mode allows for much longer distances, but it uses a completely different fibre (8 µm). By the way, due to the wave-length of the light being used (1300 nm), the opti- cal signal is invisible to the human eye. User's Guide ADI-6432R BNC © RME... -

Latest circuit designs like hi-speed digital synthesizer, digital PLL, 100 MHz sample rate and analog filtering allow RME to realize a completely newly developed clock technology, right within the FPGA at lowest costs. The clock's performance exceeds even professional expectations. -
