1. Open an M-32 AD 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 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:
1. Connect the device by USB or network cable and open the web remote.
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 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.
