Overview
Pro Convert AES67 allows you to use the audio gear you already own - your
trusted compressors, equalizers or analog power amplifiers - adapt them to the
world of audio networking with Magwell audio unit, processing receive and
transmit analog and digital audio data.
The ultra-compact Pro Convert devices are ideal for both in-studio and
portable field use. Value-added features for live production applications include
WebUI for remote control, a ¼-20 thread for mounting accessories, effectively
broadcast audio online - NDI/SRT/Icecast, and audio over IP - native AES67.
The units can be powered by either a DC adapter or via Power over Ethernet
(PoE) for further deployment simplicity.

Global Settings
Click and enter Globle Settings tab, then set the parameters that take effect globally.
Sample rate: set sample rate for your device. Options are 44.1KHz, 48KHz,
96KHz. The default value is 48KHz. Changing it will affect the sample rate of
4.4mm balanced, 3.5mm unbalanced, AES67 TX/RX, NDI TX, SRT TX, and
Icecast TX audio streams. USB audio uses fixed 48KHz sampling rate. AES67
device supports asynchronous resampling, so the change of global sample
rate will not affect the USB audio.
■
MicBias: Turn on to power the connected device with 3V. It is turned on by
default. And we recommend that it remains on when connecting
microphone.
■
ST 2110-30: SMPTE Standard - Professional Media Over Managed IP
Networks: Pulse Code Modulation Digital Audio. It is off by default. Multicast
audio streams over IP networks using IGMP protocol. The length of the
sampling data packet is 1ms. All equipments shall be sampled at 48KHz and
the sampling depth can be 16 bits or 24 bits. The number of channels in the
packet is limited by the payload size of RTP audio payload - 1440 bytes.
■
Packet time: specify transmitted unit time for AES67 streams. Options are
0.125, 0.250, 0.333, 1, and 4ms. The default value is 1ms.
■
UAC channels: options are 2 and 4 (default) channels. After configuration,
the first and third channel will be exacted for the USB sending and receiving.
And you need to restart the device to make it effective, and the windows OS
users also need to re-add your AES67 converter in "Device Manager >
Sound, audio and game controllers".
■
15

IGMP: specify IGMPv2, IGMPv3 or auto (default).
■
Stream TX bitrate: options are 128(default)/192/256kbps.
■
Input Sensitivity: specify the parameter for both 4.4mm balanced and
3.5mm unbalanced input ports. Input sensitivity is the maximum voltage
strength of an input signal that a converter can handle and still produce
unclipped full output. This is important to understand because not all audio
signals have the same voltage. And when a signal’s voltage exceeds the
input sensitivity of an amp clipping and distortion may occur. A smaller
value brings a higher volume.
■
For Unbalanced input, options are +12dBu(default), +4dBu, +0dBu, -
2dBu, 0dBV, and -10dBV.
■
For balanced input, options are +24dBu(SMPTE), +18dBu(EBU)(default),
+4dBu, +0dBu, -2dBu, 0dBV, and -10dBV.
■
Output Level: Specify the parameter for 4.4mm balanced and 3.5mm
unbalanced output ports. A greater value brings a higher volume.
■
For Unbalanced output, options are +12dBu(default), +4dBu, 0dBu, -
2dBu, 0dBV, and -10dBV.
■
For Balanced output, options are +18dBu(EBU)(default), +4dBu, 0dBu, -
2dBu, 0dBV, and -10dBV.

Configuring PTP Profile
This chapter describes how to configure the precision time protocol (PTP) on
AES67 devices.
PTP provides time synchronization accuracy to the sub-microsecond level and
can achieve both time and frequency synchronization, with low deployment
and maintenance costs, which can substantially reduced Capex and Opex.
PTP
Click and enter the PTP tab. Then you can monitor and modify current PTP configuration.
Type shows current PTP protocol version. PTPv2 is a time synchronization
protocol defined in IEEE 1588 for nodes distributed across a network. With
PTP, it is possible to synchronize distributed clocks with an accuracy of less
than 1 microsecond via Ethernet networks.
■
Priority 1: specify PTP priority 1 value when advertising the clock. The range
is from 0 to 255. The default value is 255. This value works for best master
clock selection. Lower values take precedence.
■
Priority 2 : specify the priority 2 value to use when advertising this clock.
This value is used to decide between two devices that are otherwise equally
matched in the default criteria. For example, you can use the priority2 value
to give a specific unit priority over other identical devices. The range is from
0 to 255. The default value is 255.
■
Domain: specify PTP domain (domain 0, by default) for your device. Value
ranges from 0 to 127. Each domain is completely isolated from other
domains and can therefore be seen as different PTP networks. can only be
■
17

one master in each domain; Devices in the same domain can synchronize
their clocks.
GMID shows currnet GMID of your device. The value is generated from
Ethernet Mac address by spliting the MAC address into two parts and
inserting FF-FE in the middle.
■
PTP role: specify the device to be a Master or a Slave.
■
Auto: The best master clock algorithm (BMCA) assigns the role. This is
the default setting for the default PTP profile.
■
Slave preferred: The device prefers to work as a slave clock but it is not
promsing. It also depends on the deployment and configuraions of PTP
devices within the same LAN.
■
Delay mech: Options are E2E (end-to-end) and P2P (peer-to-peer). The
default setting is E2E.
End to End means the latency through the network is calculated directly
between master and slave. The slaves sends delay requests upstream to the
master, the master responds, and the network latency is calculated. The
advantage of this method is that the network nodes do not need to be PTP
compliant, which reduces the limitations on hardware that can be used in
the network.
Peer to Peer operates by calculating the delay between egress of the
upstream node to the ingress of the downstream node (i.e. the delay down
the wire) rather than the whole network at once. It is more efficient and is
less affected by asymmetry within the network.
■
Announce: Set the period for sending announce messages which are used
to establish the synchronization hierarchy. The range is from 0.125 to 2
seconds. The default value is 0.25sec.
■
18

Checking PTP Status
Sync: Set the period for sending sync messages from master to slave.
Options are 0.125/0.25/0.5sec. The default value is 0.5sec. This parameter
will not be effective when it is a slave clock.
■
Sync: The icon lights green indicates this device has synchronized with its
master. Red indicates it is not synced with its master. Master is always green.
■
Lock to: shows GMID of current master clock.
■
Role: shows the role of your device now is either master or slave.

Viewing PTP Statistics
Date: shows current time of your device. Admistrator can modify the date at
System > General > DATE & TIME.
■
Statistical chart shows the latest 5min statistics. Fig 1 shows a typical chart
when the device works as a Master clock. Fig 2 shows how it works as a
slave clock.
If the statistics exceed ±2000ns for many times, we suggest you improve the
LAN to avoid network congestion.
