2. Introduction
Thank you for purchasing the M-32 AD Pro.
The M-32 AD Pro is a versatile multichannel format converter with exceptional audio quality across each of its channels. State-of-the-art components from audiophile grade converters have been carefully aligned to fit into a compact, 1 HU 19" rack device.
The device was designed to use the entire front for visual feedback on its state and configuration. A display with encoder allows to perform all configurations directly at the device. Thirty-two custom-inscribable labeling fields with backlight in shades of green, yellow, and red indicate the current signal level.
Each analog channel can be individually adjusted to three different sensitivities that are perfectly matched to the converter's range. While this is usually implemented with digital 'trims', the M-32 AD Pro does the adjustment in the analog domain, ensuring that the converter's signal to noise ratio is not reduced when adapting to common line levels.
Digital audio can be received, routed, and sent over MADI and AVB. While MADI remains the de-facto standard of point-to-point audio transmission, AVB has been chosen as a robust network solution based on open standards. It allows simultaneous transmission of all 32 analog channels at 192 kHz sampling frequency over a single network cable.
Various remote control protocols allow the device to be configured seamlessly via MIDI over MADI, MIDI, IEEE 1722.1 AVDECC, and a web interface accessible by network or USB connection with a browser.
The following manual provides a detailed explanation of features and their proper use. Please read the safety instructions carefully.

 | Yellow | -5 (strong yellow) |
 | Orange | -4 |
 | Red | -1 |
 | Red flashing fast | 0 (at least three consecutive samples) |
 | Red flashing slow | input muted |
3.8. Replacing the Channel Labels
No tools are required to replace the channel labels. All 32 labels are printed or written onto a single sheet.
Perform the following steps to replace the labels:
- On the left side of the cover, place your fingertip into the recess and gently pull the cover towards you.
RME M-32 AD Pro User's Guide
-
Remove the current label sheet that is held between cover and device.
-
Place a new label sheet onto the cover.
-
Put the cover back into its place, aligning the centered metal plate first. It snaps into place magnetically.
It is possible to prepare your own paper cutouts in case you frequently need to label the fields. A PDF template is available upon request from your support. When choosing the paper type, ensure that its thickness allows sufficient light to pass through.
3.9. Control Section
The M-32 AD Pro can be configured completely at the device.
To do so, the a TFT display shows a menu. The adjacent encoder knob is used to navigate and change settings.
The encoder can be pushed in order to activate an item,
and rotated left and right in order to select an item.
If the device is powered on but the display shows no content, dark mode may be active. Rotate the encoder to temporarily bypass this mode and show the display.
3.10. Power Supplies
The M-32 AD Pro has two internal power supplies (PSUs) that are connected via IEC C14 inlets labeled "PSU 1" and "PSU 2" at the rear of the device. Both are hi-performance switch mode power supplies that accept 90V to 264V AC. They are short-circuit-proof, have an integrated line-filter, are fully regulated against voltage fluctuations, and suppress mains interference.
The inlets are labeled in the sequence they appear when looking from the front of the device. This helps identifying the active power source on the display.
The power switch next to the two inlets internally disconnects the line connection of the C14 inlets to the power supplies. Ground and neutral will remain connected.
Lockable IEC plugs
The inlets can be used with special IEC power cords that have a lockable connector. Please contact a local distributor to purchase these power cords if needed.
3.11. Analog Line Input Connectors
The rear of the M-32 AD Pro features four 25-pin D-sub connectors labeled "LINE IN" with Tascam®-pinout.
These analog inputs are servo-balanced, allowing balanced and unbalanced signals to be connected without a difference in level.
When using unbalanced connections, be sure to connect pin 3 (negative/"cold") to pin 1 (ground), to avoid noise from the unconnected pin 3 input.
3.12. Analog Line Levels
The M-32 AD Pro can be adjusted to the following reference levels:
| Reference 0 dBFS Headroom at | +4dBu | Other RME devices |
| +24 +24 dBu 20 dB - | ||

3.13. MADI Connectors
The rear of the M-32 AD Pro features independent optical and coaxial MADI (AES10-2003) I/O.
Each input receives up to 64 audio channels. Auto Input (see Section 9.2.2, "Connecting Two Identical MADI Signals for Redundancy") can be activated to treat both inputs as one.
The optical "subscriber" or "square" connector (SC, IEC 61754-4) accepts both simplex and duplex multimode (MM) fibers of 50 and 62.5 m diameter and up to 2km length.
The coaxial BNC connector accepts coaxial cables with 75Ω impedance.
On the device, the characteristics and state of the signal at either input can be inspected in the INPUT section.
The presence or loss of a signal at either port is indicated on the standby screen if
- the input port is selected as clock master, or
- its audio channels are routed in the OUTPUT section.
When using the web remote, the characteristics and state of the signal at either input can be inspected in the CLOCK section.
3.14. Network Connection
On the rear of the M-32 AD Pro, an RJ45 connector labeled NETWORK provides a connection to ethernet. Two link speeds are supported: 100 Mb/s and 1 Gb/s.
A green LED (left) signals network traffic (blinking). A yellow LED (right) signals a successful link.
Both straight and crossover cables can be used (Auto MDI-X). Cable lengths of up to 100m are supported when using Cat 5e or higher classification.
The network port is used to send and receive:
- up to four AVB audio streams when connected to AVB switches and endpoints,
- remote status/control with AVDECC, and
- remote status/control with HTTP over IP routed networks.
The current link state is also shown on the display of the M-32 AD Pro. A small network port icon between the STATE and INPUT tabs can display the following states:

3.16. Word Clock
Word clock can be sent and received via 75 Ω coaxial cabling at the corresponding BNC connectors. The cable length should not exceed 100 m (330 ft).
The input is terminated with 75 Ω internally. To pass on the word clock to other devices, use the word clock output. Do not connect a T-adapter to the word clock input.
The state of an incoming word clock signal can be accessed in the CLOCK section.
Possible States:
- A green indicator shows that the signal is currently in sync with the chosen clock master.
- An orange indicator means that a word clock is received but is not in sync.
- A red indicator means that word clock is chosen as master, but a signal is not present or has a different sample rate than the chosen one.
3.17. USB 2.0 Type B Jack
The USB jack at the rear of the M-32 AD Pro provides an alternative connection method for web remote control when a network connection is not available.
RME M-32 AD Pro User's Guide
When connecting the M-32 AD Pro with a standard ("printer") USB 2.0 cable to a current Microsoft Windows™ or Apple macOS™ operating system, a network adapter will be automatically installed. This does not require additional drivers. The device can then be remotely controlled by opening the URL http://172.20.0.1.
The USB port cannot be used to stream audio signals.
3.18. Mounting the Rack Adapter Brackets

5. AVB Connectivity
Network Control
The M-32 AD Pro is an AVB endpoint device that can be configured with the IEEE Standard for Device Discovery, Connection Management, and Control Protocol for IEEE 1722™ Based Devices, in short: AVDECC.
This device does not provide an AVDECC controller for connected devices. To establish an AVB connection between devices, a separate controller is required.
There are several AVDECC controllers available for download from different manufacturers that support the commands required to
- identify the device,
- adjust its sample rate and clock source, and
- create connections to or from it.
The RME Digiface AVB includes an AVDECC controller.
Many other configuration options of the M-32 AD Pro are at this time not implemented in generic AVDECC controllers. Both the control on the device and its web remote can be used to configure additional options.
An AVDECC controller can optionally acquire the device. This means that the M-32 AD Pro is no longer configurable by display or web remote until the acquisition is released.
Audio Streaming
The M-32 AD Pro has four outgoing and four incoming stream ports. Each one can be configured to contain 4, 8, 12 or 16 audio channels.
In order to establish a connection (stream) between two AVB devices, the following conditions must be fulfilled:
- There must be a physical connection between the devices.
- All switches between the devices must be certified AVB switches (or compatible).
- An AVDECC Controller is required to find the devices and to connect them.
- The stream port size must be identical at sender and receiver.
A stream between two AVB devices is deterministic, has a fixed latency, and reserved bandwidth.
5.1. Identifying a Device Remotely
When several M-32 AD Pros are connected to the same network, each device has its own remote control. To quickly reveal which device is currently being controlled, the HTTP remote and any AVDECC controller can send an Identify command. This triggers an animation of the front panel level meters of the corresponding device.
To start device identification with the web remote:
- Open an M-32 AD Pro web remote in a browser
- Press the identify 🔔 icon. The front panel level meters of the controlled device will show an animation.
Depending on the controller, the animation may persist infinitely or stop after a short period of time.
5.2. Changing the Device Name
A custom name can be assigned to the device. It is used to identify the AVB entity with AVDECC controllers. It also allows the access to the web remote without using the IP address on Apple macOS™ computers.
The device name is stored to and recalled from presets. It is not affected by firmware updates.
Changing the device name is only possible via web remote or AVDECC controller.
To change the device name:
- Connect the device by USB or network cable and open the web remote.
Section 8.5.1, "Finding the Device on a Network"
- Open the ⚙ Settings in the web remote.
- Type a new name into the text field and press Save. The name is immediately applied.
5.3. AVB Stream Size
In an AVB network, a stream describes a connection between a talker and one or more listeners. It consists of a fixed number of audio channels at a fixed sample rate. Once a stream is connected, each AVB switch along its way ensures that the audio channels can pass in time, with a higher priority than other network traffic.
The M-32 AD Pro supports a total of four streams. Each stream can have a size of 4, 8, 12, and 16 channels. The most common stream size is 8 Channels.
When using the AVB features of Apple macOS ^™ , ensure that all streams have a size of 8 channels before acquiring the M-32 AD Pro.
5.4. AVB Network Latency
All devices in an AVB network share the same time. This allows the sending device (talker) to specify the precise point of time when its audio samples should be played out at the receiver side (listener). This is achieved by adding an offset to the current time and sending the resulting timestamp with each sample transmitted. The timestamp is called "presentation time" and has nanosecond precision. For comparison, a single sample at 48 kHz has a duration of over 20800 ns.
The receiver compares the incoming presentation time of each sample to the current time and buffers the sample until the presentation time is has come.
The offset (maximum transit time) is specified by the AVB standard as 2 ms for class A traffic, which is enough time for the signal to pass through a very large network under full load with up to seven 100 MBit/s switches along the way. By default, most AVB products will use this offset. In smaller networks with less hops or 1 GBit/s link speed, the offset can be adjusted to lower values, such as 0.3 ms, 0.6 ms or 1 ms. In the event that the chosen offset is too low, the listener detects that the requested presentation time has already passed and the audio data is discarded.
The M-32 AD Pro acts both as a talker with a specified offset of 2 ms, adjustable down to 0.3 ms, and as a listener - where the latency depends on the talker.
In AVB networks, the latency is always specified by the talker and guaranteed by the listener - with nanosecond accuracy. This behavior is plug and play and does not require any user interaction or monitoring.
5.4.1. 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 the network.
This setting can only be accessed on the web remote.
To adjust the presentation time offset:
- Connect the device by USB or network cable and open the web remote.
Section 8.5.1, "Finding the Device on a Network"
- Open the ⚙ Settings .
- Activate Expert Settings.

The device can only be locked and unlocked at the front panel. These controls are not accessible remotely.
8.4. Front Panel Illumination
The M-32 AD Pro features a unique concept for its front panel illumination, which consists of:
- A ring illumination around the standby switch that shows the overall state of the device.
- 32 channel labels with integrated backlight metering (peak or RMS).
- A display with standby screen that shows categorized warnings.
All elements have been designed to give the user thorough status feedback even from a distance. The channel backlight metering can be configured to hold over events for 5 s or infinitely. Each of the three sections can be individually switched off (dark mode).
8.4.1. Dark Mode
Each of the three front panel illumination sections can be switched off if they are not required.
To turn off illumination on the device:
- Open the visual feedback tab in the STATE section.
- Change any of the following:
a. Power to off to turn off the standby switch ring illumination.
b. Meters to off or Dim to turn off or dim channel label backlight.
c. Display to ☐ off to turn off the display.
When any item is turned off, a notification (orange) is shown in the STATE section.
To panel illumination back on:
- Open the same menu and set the corresponding switches to to On.
To turn the front panel lighting on temporarily, just rotate or push the encoder. The panel will turn back off after five seconds.
To turn off illumination on the web remote:

-
Locate the visual feedback tab in the STATE section.
-
Push the "Peak" or "RMS" button in the global metering settings.
8.4.3. Persistent Clipping Notifications
In multi-channel applications, it can be important to find out which channel clipped. A clipping is detected when three consecutive samples are digital full scale (0 dBFS). The duration of how long a clipping ("over") event is shown can be manually changed to either five seconds or infinite.
This is a global setting which affects both the remote control and the device. On the web remote, an additional peak hold is shown in the level meters.
On the device, an over notification is signaled as a fast flashing (red) of the label backlight.
Switching over notifications on or off:
- Open the visual feedback tab in the STATE section
-
Change OVR Hold to either:
-
5s to notify for five seconds
- On to notify until manually reset
- Off to deactivate over notifications
To reset infinite full scale notifications:
- Open the visual feedback tab in the STATE section.
- Activate Reset.
8.4.4. Metering of Digital Input Signals
The digital input signals can be visually inspected to ensure that audio signals are reaching the device.
To temporarily assign the 32 front panel level meters to a digital input, open the INPUT section and choose the relevant digital input tab.
In the MADI optical and MADI coaxial tabs, two toggle switches can be pushed and held to inspect either channels 1-32 or channels 33-64.
In the AVB input tab, one toggle switch per stream can be pushed and held to inspect the relevant stream.
This feature is temporary and lasts only while the encoder is pushed. Afterwards, the front panel level meters will show the level of the analog inputs.
On the web remote, each input port can be opened and level meter indicators will appear above the channel number.
8.5. Remote Control Overview
The M-32 AD Pro can be remotely controlled. Remote control is activated by default and is not affected by preset changes or device lock.
The network controls over HTTP and AVDECC operate simultaneously. Two or more controller instances are synchronized. The MIDI control works either via DIN or is embedded into either MADI signals. Both network and MIDI control can be operated at the same time.
The remote control protocols are not protected against malicious use. When activated, the remote control server allows anyone on the network to make changes to the configuration of the device. To avoid this, secure the remote control connection externally.
8.5.1. Finding the Device on a Network
The M-32 AD Pro has two integrated network adapters (USB 2.0 and Ethernet). Both adapters can be used, individually or simultaneously, to control the device with HTTP ("web remote"). The HTTP remote control works on any IP-based network, including wireless networks.
The ethernet connection additionally supports AVDECC 1722.1 remote protocol, which requires a physical connection (cables), but does not require AVB switches. Wireless routers are not supported for AVDECC.
To enable web remote functionality over HTTP:
- Open the remote tab in the STATE section.
- Ensure that the HTTP Remote setting is switched to ON.
USB
When the device is connected with a USB 2.0 cable to a Apple macOS ^™ or Microsoft Windows ^™ computer, a network device is automatically installed in the background that assigns the M-32 AD Pro the following IP address:
http://172.20.0.1
Only one M-32 AD Pro can be connected via USB at a time.
Ethernet
The integrated ethernet adapter will join an IP network when connected. If no DHCP server is found, for example when connecting the M-32 AD Pro directly to a computer, an address is automatically self-assigned (in the 169.254.0.0/16 subnet).
To find out the current IP address:
- Open the remote tab in the STATE section.
- The current IP address is displayed.
- Enter the IP address in the address bar.
Connecting to the Remote Interface without IP address
Instead of using the IP address, the device name can be entered in the browser window, followed by .local/.
By default, the name is m32-ad-pro, and the corresponding URL is therefore:
http://m32-ad-pro.local./
The length of the custom name should not exceed 63 characters. Spaces in the device name should be written as hyphens ("-") when entering the URL.
The device name is stored in a preset. Loading a preset can therefore change the device name and require a different address.
8.5.2. Web Remote
An integrated web server provides an easy-to-use remote control interface for the M-32 AD Pro. It requires a network connection from a desktop computer with a current browser version.

The information tab is located in the STATE section.
It shows the current firmware version and gPTP Grandmaster ID.
9. INPUT Section
The input section is used to inspect and configure the audio inputs of the device. A warning is displayed when an input is not present but selected as clock master, or routed to an output and is either not present or not in sync to the clock master. Related input settings, such as AVB stream size or MADI auto input, can be configured here.
9.1. Analog Inputs
The line level inputs of the M-32 AD Pro 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).
At single speed sample rates, the converters are configured with short delay 'sharp' IIR filters with extremely low latencies (5 samples) and flat frequency response over the entire audible range. At higher sample rates, a short delay 'slow' filter is used to additionally optimize the impulse response. The latency increases to six samples at quad speed (176.4 kHz, 192 kHz).
In its default state, no routing exists between the analog inputs and the digital outputs. The analog signals can be routed to two MADI ports and four AVB streams at the same time.
9.1.1. Adjusting the Input Line Level
To adjust the input line level on the device:
- Open the Analog Input tab in the INPUT section
- Initially, the cursor will highlight all input channels. To accept this, rotate the encoder to move the cursor to the current reference level
- Alternatively, pressing the encoder on the channel strip allows the selection of an individual channel
1 Cursor (current channel)
2 Input Reference Level
- Push the encoder on the current line level, then Rotate the encoder to change the setting and confirm by pushing the encoder again.
To adjust the input line level on the web remote:
-
Select either a single channel or two channels by clicking the corresponding level meter. All inputs between the two selected channels will be automatically included in the selection.
-
Press one of the corresponding buttons for +13 dBu, +19 dBu or +24 dBu. The selected value is shown within the level meter.
9.1.2. ADC Converter Mute
The analog inputs can be globally muted.
To mute the analog input channels on the device:
- Open the Analog Input tab in the INPUT section
- Toggle the ADC Standby switch to ON
To mute the analog input channels using the web remote:
-
Open the web remote and locate the analog inputs.
-
Toggle the ADC Standby switch to ON.
9.2. MADI Input
The M-32 AD Pro accepts up to two MADI signals, one electrical (BNC input) and one optical (SC input).
To connect a MADI signal:
- Ensure that you have set the correct sample rate and clock source in the CLOCK section.
- Connect the cable to the corresponding input.
- Open a MADI tab in the input section to see the current LOCK and SYNC state.
- (optional) Use the device level meters to inspect the audio signal from the incoming MADI signal (see: Section 8.4.4, "Metering of Digital Input Signals").
It is best to create a routing for the MADI signal right away, before connecting the cable to the device. This activates monitoring of the corresponding input for signal loss or clock issues. If no routing exists and the signal is not set as clock reference, plugging in a MADI signal will not lead to any visible change on the device standby screen.
9.2.1. MADI at High Sample Rates
The MADI standard (AES10) allows transport of audio at sample rates beyond 48 kHz by reducing the number of available channels.
Double speed (88.2 kHz, 96 kHz)
Double speed audio signals can be transmitted and received in two different ways. Manufacturers can implement one or both modes, usually referred to as "96k frame" and "S/MUX 2" or "legacy" mode. It is important to use the same mode on both sender and receiver side because S/MUX 2 and legacy mode are not compatible. Both modes transport the audio signal transparently.
96k frame
The so-called "96k frame pattern" (AES10) can be detected at the receiver side automatically. In this mode, the frame numbers and corresponding user bits equal the number of channels submitted. The "56 Ch." setting corresponds to 28 audio channels at 88.2 kHz and 96 kHz sample rates. The "64 Ch." setting corresponds to 32 audio channels at 88.2 kHz and 96 kHz sample rates.
S/MUX 2
Sample multiplexing (or S/MUX 2) describes a method to distribute two consecutive samples onto neighboring channels. The MADI signal remains exactly the same as in single speed with 56 or 64 channels including its user-bits. The receiver decodes the audio signal by passing the samples of channel 1+2 as two consecutive samples for channel 1, samples of channel 3+4 as two consecutive samples for channel 2, and so forth. The amount of channels corresponds to the same as the 96k frame. This format cannot be automatically detected at the receiver side.
Quad Speed (176.4 kHz, 196 kHz)
Quad speed MADI does not have a standardized frame format. Therefore S/MUX 4 is used. The encoding works the same way as S/MUX 2, except that four consecutive channels are used to transport one audio channel. This reduces the available number of channels to 14 ("56 Ch." setting) or 16 ("64 Ch." setting).
When using MADI, the sample rate of the incoming MADI signal and the expected frame format of the outgoing MADI signal must be set in the device.
Since the M-32 AD Pro has two independent MADI ports, all 32 analog inputs can be sent at 192 kHz by using both ports, each carrying 16 audio channels.
9.2.2. Connecting Two Identical MADI Signals for Redundancy
The coaxial MADI input can be configured to automatically switch to an existing MADI optical signal in case the coaxial signal fails. While existing routing and clock settings from the coaxial MADI input are kept, the port's name is changed to MADI Auto Input and its icon changes to reflect the feature. The failover is seamless if the active input loses lock abruptly (e.g. one of the cables is unplugged).
The user is notified of the lost signal with a warning and redundancy can be re-established.
For a seamless failover, the two MADI signals must be identical. However, only the 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 as long as they are in sync.
To create MADI redundancy:
- Switch on "enable MADI redundancy" in the coaxial tab of the INPUT section. The port will be renamed to MADI Auto Input.
- Create a routing from MADI Auto Input to any output.
RME M-32 AD Pro User's Guide
- If the device should also slave to MADI Auto Input, choose it as clock master in the CLOCK section.
- Connect both MADI signals with identical audio.
To create MADI redundancy using the web remote:
- Open the MADI Coaxial input port in the routing view.
- Toggle the switch "Auto Input" to ON.
9.3. AVB Input Streams
The AVB streams received by the M-32 AD Pro 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 AVDECC Controller is required. The M-32 AD Pro does not include an AVDECC Controller.
AVB input streams are monitored as follows:
| Description Indicator Possible solution | ||
| Disabled grey Create connection with AVDECC | controller | |
| Streaming/Receiving green | ||
| No Data red Verify proper talker configuration | ||
| SR Mismatch red Verify that the sample rates of talker | and listener are identical | |
| Waiting yellow ... Waiting for talker to be ready | ||
| Talker Fail red Verify proper talker configuration | ||
| No Bandwidth red Use faster network speed (1 GBit/s | instead of 100 MBit/s) | |
| Domain Boundary red Reconnect all devices and reboot | switch, ensure only AVB switches are used | |
| Internal Error red Reboot device | ||
9.3.1. Change AVB Input Stream Size
Each of the four AVB streams can have a size of 4, 8, 12 or 16 channels.
To change the amount of channels in the incoming AVB stream on the device:
- Open the AVB tabs in the INPUT section.
- Move the cursor to highlight the corresponding AVB stream size and press the encoder.
RME M-32 AD Pro User's Guide
- Rotate the encoder to configure a new stream size and confirm by pressing the encoder again.
To change the amount of channels in the incoming AVB stream with the web remote:
- Connect the device by USB or network cable and open the web remote.
- Click one of the AVB ports in the routing view. The port opens.
- Adjust the stream size to 4, 8, 12 or 16 channels and click 'Apply'.
Changing a stream size briefly interrupts all incoming and outgoing AVB streams.
10. OUTPUT Section
The output section represents the internal routing matrix and state of the outputs. Routing is performed by selecting an output and assigning any input to it. When a routing is active, its input is automatically monitored for lock and sync in the input section. For AVB stream outputs, their states are additionally monitored in the output section.
Example:
In the OUTPUT section, MADI Optical 1-12 is chosen as source for AVB Stream 2. The M-32 AD Pro 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.
Use the web remote to find out quickly which outputs are receiving a specific input signal. The web remote provides a thorough representation of all active routing connections at a glance.
Device Output Section
The device allows full inspection and configuration of outgoing signals including routing in four channel blocks.
Web Remote Output Section
The web remote integrates the output ports with a routing interface.

10.1. MADI Outputs
The MADI outputs of the M-32 AD Pro are always active. If no routing is configured, an empty stream is sent that can be used for clocking. This state is represented with a light-green Status Indicator.
10.1.1. Setting the Output Channel Format and Frame Pattern
Depending on the requirements of the receiver, it is possible to change the channel format and frame pattern of the outgoing MADI streams.
To change the channel format of both MADI outputs on the device:
- Go to one of the MADI tabs in the OUTPUT section.
- Toggle the switch to 56Ch or 64Ch to adjust number of output channels.
To change the channel format of both MADI outputs using the web remote:
- Open either MADI output port in the routing view.
- Select the channel mode from the corresponding menu.
56Ch and 64Ch format corresponds to 28/32 channels at double speed, and to 14/16 channels at quad speed.
To change the frame pattern of both MADI outputs on the device:
- Go to one of the MADI tabs in the OUTPUT section.
- Toggle the switch for 96k to use the 96k frame at 88.2 kHz and 96 kHz. .To change the frame pattern of both MADI outputs using the web remote:
- Open either MADI output port in the routing view.
- Select the frame format from the corresponding menu.
96k frame setting is only used at sample rates 88.2 kHz and 96 kHz and is otherwise ignored.
It is not possible to select separate settings for each MADI port. Both ports will be affected regardless which output tab is used to change the setting.
10.1.2. Routing Signals to the MADI Outputs
The M-32 AD Pro features two independent MADI outputs that can stream audio signals. In order to send a signal, a routing is required.
A routing immediately activates input monitoring for the corresponding input and raises a warning in the input state if the signal is not available.
To create a routing to a MADI output on the device:
- Open the OUTPUT section.
- Rotate the encoder to highlight the coaxial or optical MADI icon.
"Route Signals to MADI Coaxial/Optical Output" text will be shown on the display. - Press the encoder to open the routing. The cursor will highlight the first available channel block.
- Either rotate the encoder to select the next available channel block or press it to start assigning the source signal.
- Again, rotate the encoder to select the source for the selected output.
Choosing "unrouted" deletes an existing routing, and "cancel" aborts the routing and keeps the previous routing.
At single speed MADI, a consecutive routing of the first channels 1-32 and following channels 33-64 can be created in one step. By continuing to rotate the encoder on the output channel block field, those two ranges are followed by a finer granularity of four channels. Those are then displayed as "Channel 1-4", "Channel 5-8", etc.
To create a routing to a MADI output on the web remote:
- Click the MADI coaxial or MADI optical output port.
- Select and click a block of four channels by clicking it. The channels will be highlighted in blue.
- Open any input port and click a block of four channels. A routing is created and displayed with a connection line.
10.1.3. MADI Daisy Chains
MADI is a uni-directional protocol with a fixed number of channels. When more than two MADI devices are connected, a serial connection is required. This is also referred to as a "daisy chain". The output of the first device is connected to the input of the second device, the output of the second device to the input of third device, and so on, until the signal is plugged into the input of the first device.
It is important to understand that each device must be programmed to pass on audio from its MADI input to the MADI output. Otherwise, the last device would only receive the channels of one device.
While many RME devices pass on MADI signals automatically, the M-32 AD Pro must be explicitly configured to do so.
In order to pass on signals, configure the output routing of the required output port to pass on the signal from the MADI input port.
The latency of the MADI I/O is four samples.
10.1.4. MADI Port Mirroring
A redundant MADI connection protects from loss of audio in case of a single cable failure. To achieve redundancy, the receiver must support MADI redundancy. The sender must send two identical MADI signals on two outputs, usually the BNC coaxial and SC optical ports.
The M-32 AD Pro features independent routing for both MADI output ports. For this reason, a "mirroring" of the signal must be manually created. In order to do this, the routing of the two MADI outputs should be configured to contain the same routing.
The receiving device usually ignores the audio contents of the two MADI signals. Therefore, the redundancy may appear to be set up even though the M-32 AD Pro sends different audio signals on both ports.
10.2. AVB Output Streams
The AVB streams leaving the M-32 AD Pro are described as "output streams". In this case, the device acts as a talker. The talker defines the presentation time and therefore the latency across the network. This is set per default to 2 ms.
The output streams of the M-32 AD Pro are by default empty, containing a clock signal but no audio signal. To send audio with AVB, a routing must be created for each outgoing stream.
To establish a connection between a talker and a listener, an AVDECC controller is required. The M-32 AD Pro does not include an AVDECC controller.
Outgoing AVB streams are monitored by the device as follows:
| Description Indicator Possible solution | ||
| Disabled grey Create connection | with AVDECC | controller |
| Streaming/Transmitting green | ||
| SR mismatch red Verify that the sample rates of | talker and listener are identical | |
| Waiting yellow ... Wait for listener to be ready | ||
| Listener Fail red Verify proper listener | configuration | |
| No Bandwidth red Use faster network speed (1 | GBit/s instead of 100 MBit/s) | |
| Domain Boundary red Reconnect all devices and | reboot switch | |
| Internal Error red Reboot device | ||
10.2.1. Change AVB Output Stream Size
Each of the four AVB streams can have a size of 4, 8, 12 or 16 channels.
To change the amount of channels in the outgoing AVB stream on the device:
- Open one of the four AVB tabs in the OUTPUT section.
- Move the cursor to highlight the current AVB Stream Size and press the encoder.
- Rotate the encoder to configure a new stream size and confirm by pressing the encoder again.
To change the amount of channels of the outgoing AVB stream:
- Connect to the device remotely (see: Section 8.5.1, "Finding the Device on a Network").
RME M-32 AD Pro User's Guide
- Open an AVB port in the routing area and use the up and down arrows to adjust the stream size
- Click Apply.
Changing a stream size briefly interrupts all incoming and outgoing AVB streams.

11.1. Clock status
The clock of all digital inputs is continuously monitored with SyncCheck™ and shown in the CLOCK section. A warning occurs when the chosen clock master fails. A caution is displayed when a routed signal is out of sync. A caution notification is displayed when a signal is present, but not in sync and not routed. A good notification is displayed when a signal is present and in sync, but not routed or chosen as clock master. A confirmation is shown when the signal is present and either chosen as master or routed and in sync.
On the standby screen, the two possible notifications are not shown. Those signals are not relevant to the current device state.
11.2. Master Clock
In its the default state, the M-32 AD Pro uses an internal clock signal (master). This means that any connected device must synchronize to it (slave).
Alternatively, one of the digital inputs (word clock, MADI optical, MADI coaxial, and each of the four AVB
streams) can be chosen as clock reference. This activates SteadyClock™ FS, a technology that extracts a low jitter clock signal from the incoming signal.
Intelligent Clock Control (ICC) automatically changes the clock source when the chosen master clock fails. Using the feedback of SyncCheck™, the M-32 AD Pro will change to another source signal that is in sync, maintaining the slave mode and current sample rate. If no other source is available, the device will fall back to its internal clock until the chosen master has recovered. Due to the excellent performance of RME's clock technology, disconnection and re-connection of a master clock is likely to be performed without losing a sample in the outgoing audio signal.
ICC switches the clock source between word clock, MADI optical, MADI coaxial, and internal, seamlessly, when the MADI optical, coaxial or word clock inputs fail and the other port is locked - or to internal. ICC will not fall back to an AVB sync source and also will not affect a chosen AVB master clock.
11.2.1. Selecting a Master Clock
To configure the clock master on the device:
- Enter the CLOCK section. The cursor highlights the currently selected clock.
- Push the encoder. Two blue arrows are shown to indicate that the encoder can now be used to change the current setting.
- Rotate the encoder until the preferred clock source is shown.
- Push the encoder again to activate the setting.
To configure the clock master on the web remote:
- Locate the CLOCK section.
- Use the Master: dropdown menu to choose a clock source. The new clock source is applied immediately.
11.3. Sample Rates Overview
The M-32 AD Pro supports the following sample rates:
Supported sample rates
| Single speed 32 kHz, 44.1 kHz, 48 kHz | |
| Double speed 88.2 kHz, 96 kHz | |
| Quad speed 176.4 kHz, 192 kHz |
If the device is clock master, these rates always correspond to the actual sample rate used.
11.3.1. Slave Mode
When the device is slave, certain deviations are automatically accepted to avoid interruption of the outgoing audio signal when the sample rate changes. This is called Intelligent Clock Control (ICC). It also handles deriving a sample rate of double or quad speed based on an incoming rate.

There is no ICC mechanism necessary for AVB; the device will always use the exact clock from the corresponding AVB stream.
It is not recommended to sync devices with a higher sample rate than the current sample rate, because two devices could choose different edges of the incoming clock signal.
ICC does not affect outgoing AVB streams. Outgoing AVB streams will always correspond to the exact sample rate set in the CLOCK section. When the word clock or MADI master changes from 96kHz to 88.2 kHz, and the internal clock is set to 48kHz, the AVB streams will be offline.
11.3.2. Number of Channels
The supported number of channels per port or stream at different sample rates is shown in the following table.
Supported number of audio channels per stream/port and direction at different sample rates
| 32 kHz 44.1 | kHz 48 kHz | 88.2 kHz 96 kHz | 176.4 kHz | 192 kHz | |||
| MADI 56 Ch | 56 56 56 28 | 28 14 14 | |||||
| MADI 64 Ch | 64 64 64 32 | 32 16 16 | |||||
| MADI 56 Ch + 96k | --- --- --- 28 28 --- --- | ||||||
| MADI 64 Ch + 96k | --- --- --- 32 32 --- --- | ||||||
| AVB 4 Ch stream | --- 4 4 4 4 4 4 | ||||||
| AVB 8 Ch stream | --- 8 8 8 8 8 8 | ||||||
| AVB 12 Ch stream | --- 12 12 12 12 12 12 | ||||||
| AVB 16 Ch stream | --- 16 16 16 16 --- --- | ||||||
i
Since there are two independent MADI ports, the total supported number of channels can be multiplied by two. Since there are four independent AVB streams, the total supported number of channels can be multiplied by four. The analog channel count is always 32 regardless of sample rate. The maximum amount of digital inputs is 192 channels (at 48 kHz, 64 Ch MADI). The maximum amount of digital outputs is 192 channels (at 48 kHz, 64 Ch MADI).
11.3.3. Selecting a Sample Rate
To configure the device sample rate on the device:
- Enter the CLOCK section. The cursor highlights the currently selected clock.
- Rotate the encoder to highlight the current sample rate.
- Push the encoder. Two blue arrows will appear to indicate that the encoder can now be used to change the current setting.
- Rotate the encoder until the preferred sample rate is shown.
- Push the encoder again to activate the setting.
To configure the device sample rate on the web remote:
- Locate the Select sample rate drop down menu in the CLOCK section.
- Select a sample rate from the drop down menu. The new rate is automatically applied.
11.3.4. Effects of Sample Rate Changes on Existing Routing
The M-32 AD Pro saves one routing table per preset, regardless of sample rate. A change of sample rate or MADI frame mode can reduce the number of input and output channels available for routing. This does not alter the routing table. Any existing routing is hidden until another change of sample rate reenables the channels.
Example:
A routing is created at 96 kHz with 32 channels, sending the MADI coaxial Input 1-32 to optical MADI Output 1-32. If the sample rate is now changed to 176.4 kHz and the 56 Ch frame is activated, only the first 14 channels of MADI coaxial input are routed to the optical output. Switching the sample rate to 44.1 or 48 kHz will reveal the previous routing for 32 channels.
11.4. Set Word Clock Output to Single Speed
At sample rates > 48 kHz, it may be necessary to synchronize two devices with a fraction of the actual sample rate:
| Sample Rate Word Clock Full Speed | peed (default) Word Clock Single Speed | speed (option) |
| 88.2 kHz 88.2 kHz 44.1 kHz |
RME M-32 AD Pro User's Guide
| Sample Rate Word Clock Full Speed (default) Word Clock Single Speed (option) | ||
| 96 kHz 96 kHz 48 kHz | ||
| 176.4 kHz 176.4 kHz 44.1 kHz | ||
| 192 kHz 192 kHz 48 kHz | ||
To set the Word Clock output to single speed on the device:
- Open the CLOCK section.
- Move the cursor onto the toggle switch Word Out Single and push the encoder to change the value.
To set the Word Clock output to single speed on the web remote:
- Locate the CLOCK section.
- Move the cursor onto the Word Out Single switch and push the encoder to change the value.
