m fibre cables are supplied with each Alpha link Live-R which can be used for initial testing or if the units are adjacent to
the Blackrock processor.
It is the responsibility of the facility or system integrator to supply longer fibre cables that may be necessary to allow the
Alpha-Link units to be remotely located.
Each unit will require one or two fibre cable runs depending on the method of connection to the Blackrock. The diagrams
opposite show the different connection arrangements.
• Cable specification is: 50/125µm, multimode, duplex LC (at the Blackrock) to SC (at the Alpha-Link).
• Singlemode 9/125µm cables cannot be used.
• It is recommended that spare cables are run to remote units to allow for damage or future expansion.
Suitable cables are readily available from networking and computer supply outlets.

Balanced analogue inputs and outputs are available via the D25 connectors. Each connector provides eight channels.
%
Four input circuits and four output circuits of 110Ω balanced AES/EBU are provided on each connector. Use only
appropriately matched 110Ω cable for the connection of digital equipment.
Digital channels 1–4 feature SRC conversion on their inputs. All other digital inputs operate at the system sample rate.

A 1U, 32-channel, BNC converter/breakout panel is available for the connection of 75Ω unbalanced digital equipment.
Panels can be ordered with either 1m or 3m connection cables. Note that 3m is the maximum distance at which the panel
can be located.

The Alpha-Link Live unit does not feature twin MADI fibre ports. The creation of redundant connections to this unit will
therefore require the use of an external fibre changeover switch.
