RAVENNA
Technical Notes:
Windows 7 (32 bit) mandatory for MassCore Ravenna (XP not supported)
VS3 Control Panel Ultra/Extra low latency are not supported in Ravenna mode
Find the Recommended configuration for Pyramix v8 Ravenna here
http://www.merging.com/pages/pcconfig
The Horus Ravenna interface is limited to 32 input Banks + 31 output Banks
E.g. 32 banks of 8 inputs channels under Easy Connect equals a 256 inputs limit
For ultimate performance we recommend that under Easy Connect you enable only the necessary
connections, as every extra Ravenna connection will use some bandwidth (Core or Network)
Ravenna user should avoid connecting multiple Horus to any a router/Network not certified by
Merging. Refer to the Merging Ravenna MassCore Guide for all details on the certified Ravenna
switch and configuration
Only Ravenna devices can be connected to the Merging PCIe Ethernet Controller Card NET-MSC-
GBEX1. Avoid mixing up non-Ravenna device on this network, like Controllers such as
Tango/Isis/Euphonix or other network devices. The same will apply if you are connected to the
Dell Power Connect 2816 certified for Ravenna network use.
Don’t connect a 100MB Ethernet device if the switch is not multicast; otherwise the flow control
will reduce drastically the bandwidth
When configuring the VS3 Control Panel it will not be possible to choose a mode where both
Mykerinos and Ravenna will function at the same time. User must either work in MassCore
Mykerinos or MassCore/Ravenna or Native
MassCore/Ravenna NET-MSC-GBEX1 PCIe Ethernet card users might have to wait up to 2 minutes
after their system startup/login before the Horus shows up online and in MT Discovery
A Ravenna ASIO driver is available for Horus users that wich to use their notebook GbE Network
RJ-45 system socket. Refer to http://www.merging.com/horus/download
Known issues:
Horus Ravenna: Switching from MADI Standard (56) to MADI Extended (64) can generate small
glitch, avoid doing so during realtime operations
Be aware that non-certified Ravenna configurations might not capable of sustaining 384 I/O @ 1FS
(44.1/48 kHz). If you experience noise similar to static reduce the Ravenna I/O count enabled in
the Ravenna Easy Connect
Merging recommends that Ravenna users disable the Windows Firewall, as it can partially block
some of the Ravenna I/O connections
Peaks might show up under Pyramix Core section if you power OFF or disconnect the Horus.
Recommendation: A valid connection an online Horus is always required if the Horus is PTP
Master. Reset peaks by Mouse Clicking on the Core section.
Avoid changing a network address on your system or disconnecting Ethernet ports on your system
when MassCore Ravenna is running
Cannot use the ISIS since running Ravenna with the Merging PCIe Ethernet Controller Card NET-
MSC-GBEX1
Recommendation: Refer to the ISIS support document below

Connections:
In order to create Ravenna I/O connections please refer to the Ravenna Easy Connect guide (installed
along with Pyramix)
Each Horus will then appear in your Ravenna Easy Connect utility where you will see the name of each
Horus online. You will be able to dispatch each Horus I/O connections with the Ravenna Easy Connect
utility.
