  • Page 43 9.1. Analog Inputs The line level inputs of the M-32 AD Pro II accept levels of up to +24 dBu. Each individual channel has its own line level setting of +13/+19/+24 dBu which can also be adjusted remotely. Additionally, the AD converters can be globally set to standby (mute).
  • Page 44 3. Press one of the buttons for +13 dBu, +19 dBu or +24 dBu below the selection. The selected value is shown within the level meter. 9.2. MADI Inputs The M-32 AD Pro II accepts up to two MADI signals, one electrical (BNC input) and one optical via optional SFP module (LC input). To connect a MADI signal: 1.
  • Page 45  SYNC and LOCK states are evaluated to confirm the current input state. It is therefore possible to send two different signals to the M-32 AD Pro II as long as they are in sync. To create MADI redundancy: 1. Switch on "enable MADI redundancy" in the coaxial tab of the INPUT section. The port will be renamed to MADI Auto Input.
  • Page 46 RME M-32 AD Pro II User’s Guide 9.3. AVB Input Streams The AVB streams received by the M-32 AD Pro II are referred to as "input streams". For these streams, the device acts as an AVB Listener. To establish a connection between a talker and a listener, an ATDECC Controller is required. The M- 32 AD Pro II does not include an ATDECC Controller.

  • Page 48 In the OUTPUT section, MADI Optical 1-12 is chosen as source for AVB Stream 2. The M-32 AD Pro II is clock master, but the incoming MADI signal is not correctly synchronized. This causes a warning in the INPUT section. If MADI Optical is not routed to any output, an invalid or missing signal does not cause a warning.
  • Page 49 10.2. MADI Outputs The MADI outputs of the M-32 AD Pro II are always active. If no routing is configured, an empty stream is sent that can be used for clocking. The state without routing is represented with a light-...

  • Page 52 RME M-32 AD Pro II User’s Guide 10.3.2. Adjusting the Network Latency The default presentation time offset of 2 ms for outgoing streams can be changed when lower latencies are required. Reducing the offset to a lower value can prevent audio to be played out depending on ...
  • Page 53 Intelligent Clock Control (ICC) automatically changes the clock source when the chosen clock reference input does not detect a valid signal. Using the feedback of SyncCheck™, the M-32 AD Pro II will change to another source signal that can be used as a clock reference. If no other source is available, the device will fall back to its internal clock until the chosen clock reference has recovered.
  • Page 54 RME M-32 AD Pro II User’s Guide clock reference is likely to be performed without losing a sample in the outgoing audio signal.
