SUMMARY OF NEW FEATURES
Version 3.11 software for the Akai DR16pro includes the following new features and
improvements:
• Addition of multi-machine synchronisation system that allows multiple DR16pro
transports to be accurately locked together, even while jogging.
• Ability to load new operating systems from Mac HFS format CD-ROM disks.
• Support for IB-D8TIF, 8-channel TDIF digital audio option board.
• Other bug fixes and improvements.
Please refer to the rest of this document for further information and for details of changes.
MULTI-MACHINE SYNCHRONISATION
The new multi-machine synchronisation function allows multiple DR16pro machines to be
accurately synchronised for playback and recording. The system uses a combination of the
AKAINET connections on each machine (to pass synchronisation messages from one
machine to another) and the SYNC IN/OUT connections on each machine (to synchronise
the sample clocks of each machine in the system).
When configured for multi-machine synchronisation, the SLAVE machines will remain locked
to the MASTER machine and will follow any transport commands given to the MASTER
machine (including playback and record as well as locate functions).
With the addition of an Akai RE32 Multitrack Remote Controller, the system will behave as
if there is a single ‘multitrack’ project encompassing all the tracks allowing editing, transport
control and record functions across the entire system.

MULTI-MACHINE CONNECTIONS
On the rear panel, you will find two BNC connectors, each with a terminator switch:
The AKAINET and SYNC IN/OUT connectors must both be connected as described in the
following sections to enable the multi-machine synchronisation function to be used.
Akainet (Ethernet) Connections
The AKAINET connectors on each DR16pro should be connected together to allow multimachine synchronisation messages to be passed from one machine to another. This should
be done using standard Ethernet BNC cables. These are chained between the AKNET BNC
connectors on each DR16pro using BNC ‘T’ connectors to link each cable where necessary.
If you are using an RE32 Remote Controller, this should also be connected to the AKAINET
bus as described in the RE32 manual.

Version 3.11 Addendum
It is essential that the AKAINET TERMINATOR switch is switched to the ON position on
the first and last units in the chain. Failure to do so will prevent correct communications
and the system will not work correctly.
NOTE: The AKNET interface used in the Akai DR16pro system is 10-Base-2
Ethernet. There are certain rules that must be adhered to when setting up the system
to ensure reliable operation:
• All cables should be 50 ohm impedance.
• There should be a maximum of 185m of cable in the system between the first and
last nodes.
• There should be at least 0.5m of cable between each connection.
Sync Connections
The SYNC IN/OUT connectors on each DR16pro should be connected together to allow the
internal sample clocks of each machine in the system to be synchronised. This should be
done using standard video BNC cables. These are chained between the SYNC IN/OUT
BNC connectors on each DR16pro using BNC ‘T’ connectors to link each cable where
necessary.
It is essential that the SYNC IN/OUT TERMINATOR switch is switched to the ON position
on the first and last units in the chain. Failure to do so will prevent the system from
synchronising correctly.
