Hapi User Manual
AES-EBU
1 x D-SUB25 connectors providing 8 channels (4 AES pairs) of AES-EBU I/O are Included as standard
(as is the MADI module).
ADAT/SPDIF
8 ADAT I/O or 2 SPDIF I/O (on TOSLINK) are Included as standard. This module is supported up to
2FS (96 kHz)
Signal routing paradigm
Hapi is quite possibly the most flexible audio interface ever designed. Users can literally route any input
signal to any output module. Better yet, it can route any input signal to any combination of output
modules. Routable in blocks of 8 channels, a user can send 8 Mic Inputs to 8 AES outputs. At the same
time these 8 mic inputs can also be sent via the MADI outputs and included in the RAVENNA stream.
RAVENNA IP Audio
Using RAVENNA IP audio, Hapi can connect to a standard network, using off the shelf switches and
other IT technology to become a node on a LAN. From that point, any other RAVENNA node can
receive information from and deliver information to, any combination of RAVENNA devices on the
network. It is a revolution in Audio technology and will soon mean the end to costly audio routers and
matrices and allow any facility an immense amount of flexibility. From Broadcast and TV/Film post-
production, to music, live events, theatres, cruise ships and many more applications, the RAVENNA
Enabled Hapi interface will reinvent how systems come together.
Synchronization and Control information
Audio is not the only information that can pass down the RAVENNA connection. Hapi is able to send
sync and control information such as LTC/MIDI/RS-422 and GPIO down the same wire to and from the
Hapi unit.
Key Specifications
Please see the sections below for the measurement performed on the circuitry inside the Hapi unit.
