MADI 1 to 4
The Compact Engine can be delivered with 0, 2 or 4 external MADI ports to connect multi-channel digital audio.
Each port supports 64 bi-directional channels.
The odd/even port pairs (1/2, 3/4) can be configured to operate as main and redundant connections.

ETHERNET
The ETHERNET port connects other devices to the Compact Engine control system. Applications include remote
control via TCP/IP; networking to other products; updating firmware and uploading a configuration.

Expansion Slots x 2 - additional IO
The two expansion slots can be fitted with any of the following IO cards:
·
LINE IO (952/31) - 8 x line level in + 8 x line level out.
·
AES3 IO (952/32) - 4 x AES3 in (with SRC) + 4 x AES3 out (with SRC).
·
MIC/LINE IO (952/36) - 4 x mic/line in + 4 x line level in.
·
RAVENNA IO (952/38) - 2 x AoIP ports, supporting either 8 in/out or 64 in/out with the internal MADI
bridge option.
Cards can be fitted to either slot position, but to use all 64 channels of a RAVENNA IO card it must use the left
slot (7) to support the internal MADI bridge.
IO cards must
NOT
be exchanged while the frame is powered, as to do so may damage the card and/or
Compact Engine.
