RME M-32 DA Pro User’s Guide
2. Introduction
Thank you for purchasing the M-32 DA Pro.
The M-32 DA 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 custominscribable 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 DA 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,

5. AVB Connectivity
Network Control
The M-32 DA 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
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.
an AVB connection between devices, a separate controller is required.
Many other configuration options of the M-32 DA 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 DA
Pro is no longer configurable by display or web remote until the acquisition is released.
Audio Streaming
The M-32 DA 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:
1. There must be a physical connection between the devices.
2. All switches between the devices must be certified AVB switches (or compatible).
3. An AVDECC Controller is required to find the devices and to connect them.
4. 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 DA 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:
5. AVB Connectivity | 16
RME M-32 DA Pro User’s Guide
1. Open an M-32 DA Pro web remote in a browser
2.
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 AppleÊmacOS™
computers.
The device name is stored to and recalled from presets. It is not affected by firmware
Changing the device name is only possible via web remote or AVDECC controller.
To change the device name:
1. Connect the device by USB or network cable and open the web remote.
updates.
Section 8.5.1, “Finding the Device on a Network”
2.
Open the Settings in the web remote.
3. 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 DA 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 AppleÊmacOS™, ensure that all streams have a size of 8
channels before acquiring the M-32 DA 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.
5.2. Changing the Device Name | 17
RME M-32 DA Pro User’s Guide
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 DA 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
This setting can only be accessed on the web remote.
To adjust the presentation time offset:
1. Connect the device by USB or network cable and open the web remote.

8.4. Front Panel Illumination
The M-32 DA 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).

8.5. Remote Control Overview
The M-32 DA 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
8.5.1. Finding the Device on a Network
The M-32 DA 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.
configuration of the device. To avoid this, secure the remote control connection
externally.
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:
1. Open the remote tab in the STATE section.
2. Ensure that the HTTP Remote setting is switched to ON.
USB
When the device is connected with a USB 2.0 cable to a AppleÊmacOS™ or MicrosoftÊWindows™
computer, a network device is automatically installed in the background that assigns the M-32 DA Pro
the following IP address:
http://172.20.0.1
Only one M-32 DA 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 DA Pro directly to a computer, an address is automatically selfassigned (in the 169.254.0.0/16 subnet).
To find out the current IP address:
1. Open the remote tab in the STATE section.
8.5. Remote Control Overview | 30
RME M-32 DA Pro User’s Guide
2. The current IP address is displayed.
3. 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-da-pro, and the corresponding URL is therefore:
http://m32-da-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 DA Pro. It
requires a network connection from a desktop computer with a current browser version.

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. MADI Input
The M-32 DA Pro accepts up to two MADI signals, one electrical (BNC input) and one optical (SC input).
To connect a MADI signal:
1. Ensure that you have set the correct sample rate and clock source in the CLOCK section.
2. Connect the cable to the corresponding input.
3. Open a MADI tab in the input section to see the current LOCK and SYNC state.
4. (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.
9.1.1. 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
9. INPUT Section | 34
RME M-32 DA Pro User’s Guide
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 DA Pro has two independent MADI ports, all 32 analog outputs can be
received at 192 kHz by using both ports, each carrying 16 audio channels.
9.1.2. 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 reestablished.
For a seamless failover, the two MADI signals must be identical. However, only the
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.
2. Create a routing from MADI Auto Input to any output.
3. If the device should also slave to MADI Auto Input, choose it as clock master in the CLOCK section.
4. Connect both MADI signals with identical audio.
To create MADI redundancy using the web remote:
1. Open the MADI Coaxial input port in the routing view.
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 DA Pro as long as they are in sync.
2. Toggle the switch "Auto Input" to ON.
9.2. AVB Input Streams
The AVB streams received by the M-32 DA Pro are referred to as "input streams". For these streams, the
device acts as an AVB Listener.
9.2. AVB Input Streams | 35

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 DA Pro is
clock master, but the incoming MADI signal is not correctly synchronized. This causes a warning in the

10.1. Analog Outputs
The line level outputs of the M-32 DA Pro operate at +13 dBu, +19 dBu, or +24 dBu. Each individual
channel has its own line level setting, which can be adjusted remotely. Additionally, channels can be
muted globally or individually.
In its default state, no routing exists between the digital inputs and the analog outputs. Each group of
four consecutive outputs can receive its signal from any digital input that is connected and
synchronized.
At all sample rates, the converters operate with short delay IIR filters. At single speed, a short delay
'sharp' filter is used to ensure linear frequency response. At double and quad speed, a short delay 'slow'
filter is used to optimize the transient response of the M-32 DA Pro while maintaining linear frequency
response in the audible range.
The resulting latencies are 7 samples at single speed and 5.5 samples at sample rates > 48 kHz.
10.1.1. Adjusting the Output Line Level

10.2.1. 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:
1. Go to one of the MADI tabs in the OUTPUT section.
2. 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:
1. Open either MADI output port in the routing view.
2. 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:
1. Go to one of the MADI tabs in the OUTPUT section.
2. 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:
3. Open either MADI output port in the routing view.
4. 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.
10.2.2. Routing Signals to the MADI Outputs
The M-32 DA 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:
1. Open the OUTPUT section.
2.
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.
10.2. MADI Outputs | 41

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.
10.2.3. 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 DA Pro must be
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.
explicitly configured to do so.
The latency of the MADI I/O is four samples.
10.2.4. 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 DA 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 DA Pro sends
different audio signals on both ports.
10.2. MADI Outputs | 42
RME M-32 DA Pro User’s Guide
10.3. AVB Output Streams
The AVB streams leaving the M-32 DA 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 DA 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
DA Pro does not include an AVDECC controller.

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 DA 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
11. CLOCK Section | 45
RME M-32 DA Pro User’s Guide
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 DA 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:
1. Enter the CLOCK section. The cursor highlights the currently selected clock.
2. Push the encoder. Two blue arrows are shown to indicate that the encoder can now be used to
change the current setting.
3. Rotate the encoder until the preferred clock source is shown.
4. Push the encoder again to activate the setting.
To configure the clock master on the web remote:
1. Locate the CLOCK section.
2. 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 DA 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. Sample Rates Overview | 46
RME M-32 DA Pro User’s Guide
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.

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:
1. Enter the CLOCK section. The cursor highlights the currently selected clock.
2. Rotate the encoder to highlight the current sample rate.
3. Push the encoder. Two blue arrows will appear to indicate that the encoder can now be used to
change the current setting.
4. Rotate the encoder until the preferred sample rate is shown.
5. Push the encoder again to activate the setting.
To configure the device sample rate on the web remote:
1. Locate the Select sample rate drop down menu in the CLOCK section.
2. 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 DA 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 (default) Word Clock Single Speed
(option)
88.2 kHz 88.2 kHz 44.1 kHz
11.4. Set Word Clock Output to Single Speed | 49
RME M-32 DA 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:
1. Open the CLOCK section.
2. 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:
