Long story short, if you need use an Avid S3L-X with macOS and playback via AVB, do not install macOS High Sierra. macOS Mojave works fine, as does the older macOS Sierra, but High Sierra has clocking issues that manifest as constant clicking during playback, rendering the audio unusable.
If all you need to do is record via AVB, macOS High Sierra works without issue.
Note, all versions of macOS High Sierra through 10.13.6 are affected.
[Update 2019-03-03] I continue to have no problems with macOS Mojave (currently 10.14.3).
[Update 2018-09-29] Preliminary testing with macOS Mojave (10.14.0) and 64-channel recording and playback indicates that the AVB problems have been fixed.
[Update 2018-07-28] Increased affected versions to 10.13.6.
[Update 2018-06-05] Increased affected versions to 10.13.5.
[Update 2018-03-31] Increased affected versions to 10.13.4.
The E3 engine can be remotely powered on and started using the Wake-on-LAN protocol.
To remotely wake the E3 engine, you need three things:
- A computer that is connected to the same Ethernet network as the E3 engine.
- The MAC address of the engine. You can get the MAC address by going to the Options > Devices tab and right-clicking on the E3 engine image.
- The IP subnet address of the network. (Optional, depending on the software used.)
To shut the E3 engine down, use the VENUE Options > System > Shutdown button.
Software to wake the E3 engine
There are several software packages available to send the special Wake-on-LAN Magic Packet.
- Wake On Lan by Depicus (Mac App Store, $1.99)
- Remote Desktop (Apple, $79.99) – Also useful for controlling the S3L-X remotely.
- MagicPacket by DecaTec (Microsoft Store, Free)
- Wake On Lan by Sepiro Ltd (Microsoft Store, Free)
For those comfortable with the command-line, a short Python script will also do the job. Save this script somewhere as wakeonlan.py and make it executable with chmod +x.
if len(sys.argv) < 3:
print "Usage: wakeonlan.py <ADR> <MAC> (example: 192.168.1.255 00:11:22:33:44:55)"
mac = sys.argv
data = ''.join(['FF' * 6, mac.replace(':', '') * 16])
sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
sock.setsockopt(socket.SOL_SOCKET, socket.SO_BROADCAST, 1)
sock.sendto(data.decode("hex"), (sys.argv, 9))
Myself, I keep a copy of the script in my ~/usr/bin directory. To wake my system, I call the command like this, where 172.16.0.255 is the subnet of my network, and 00:90:fb:4a:13:9e the MAC address of my E3 engine.
$ ~/usr/bin/wakeonlan.py 172.16.0.255 00:90:fb:4a:13:9e
Stage 16 Box
The Stage 16 Box cannot be remotely power cycled without additional equipment. Some suggestions include:
- Furman CN-1800S + Furman BB-RS232 giving control via Ethernet.
- Furman M-8S (US) or the Furman PS-8RE III (Europe) connected to the GPIO connection from the E3 engine, along with an event (saved in the default show) to latch a GPIO when the system is started. Attempt only if you feel comfortable with electronics. If you would like me to build this setup and demonstrate it, send me an email.
