The Alpha-Link LIVE-R is a 2U high 300mm deep 19" rack unit featuring dual power supplies for on-air reliability.
Output levels at 0dBfs are user adjustable to cover the range +14dBu to +24dBu.*
Each Alpha-Link LIVE-R provides 24 channels of line-level analogue input & output and also 24 channels of AES/EBU input
& output. Digital channels 1–8 feature sample rate conversion on their inputs; circuits 9–24 operate at the system sample
rate.
Line level outputs from the 8-RMP remote mic amps connect to the Alpha-Link LIVE-R analogue inputs. When allocating audio
circuits ensure that a sufficient number of connectors are reserved for any microphone channels.

Alpha-link LIVE-R units are connected to the Blackrock processor using fibre optic cabling. Suitable cables should be
installed by the facility. Fibre specification is: 50/125µm multimode duplex LC to SC.
Each unit is equipped with two MADI connectors*. MADI-1 is the default input. Should the MADI-1 signal become lost –
as a result of a broken or disconnected fibre – the unit will automatically switch to its MADI-2 input.
Each Alpha-Link is supplied with one 2m fibre cable. This cable is intended to be used for initial testing only. It is the
responsibility of the facility to provide the longer fibre cables necessary to remotely locate the Alpha-Link units.

Alpha-Link Live is operationally the same as the 'LIVE-R except in the following areas:
• Only a single MADI fibre connector is included. See panel layout opposite.
• Two versions of the unit are available which provide either +18dBu or +24dBu analogue output level at 0dBfs. This
setting is NOT user-selectable so the version required must be specified at the time of order.
• The 'RMP 1, 2 & 3' control connectors have a different pinout. Standard Ethernet cables CANNOT be used.
Refer to Appendix page 6-12.

• The additional 'Expansion Port' connector is not used so does not require a connection.
C10 HD Installation Manual
Description
8 channels, balanced, line-level audio input or output per connector.
4 AES/EBU input pairs plus 4 AES/EBU output pairs per connector.
MADI audio data link to the console DSP processor.
Control link to the 8-RMP remote mic units. Standard Ethernet cables can be used.*
Video sync input required. (Alternatively, sync can derived from the incoming MADI stream
but with slightly reduced technical performance.)
Provides a source of Wordclock output locked to console sync input.
No connection required. Service diagnostic use only.*
