All units are fitted with auto-ranging power supplies which will accept mains voltages which range from 100 to 240V ±10%
without adjustment. The mains rating label is located adjacent to the mains input socket on the centre section power inlet
panel.
THE MAINS SAFETY EARTH MUST BE CONNECTED.
THE TWO POWER SOURCES MUST NOT BE FROM DIFFERENT PHASES OF A 3-PHASE SUPPLY.
For live transmission work it is normally recommended that one of the power feeds should be from an uninterruptable
source. (Refer to note on page 2-5 relating to UPS units).

The console is fitted with an M6 earth bolt on each mains input panels. This is an optional safety earth connection for
external equipment or where the power supply ground may be inadequate. This point is directly linked to the console
chassis and to the earth pin of the incoming power lead.

A sync input signal is required by the Blackrock processor(s), each Alpha-Link LIVE-R* and a MORSE router (where
applicable). Sync signals are not required by Alpha-Link 8-RMP or RIO units. See page 2-5 for the sync requirements.
Refer to the diagram opposite for the recommended sync distribution arrangement.
Note that the Blackrock processor(s) do not include internal termination. Termination needs to be provided by fitting the
BNC adapter and termination plugs; these items are located in the console’s trim kit.
* If an Alpha-Link LIVE unit is positioned at a remote location where it is impossible to provide a sync signal the unit can be
configured to use its incoming MADI signal as the sync reference. See page 8 of the Alpha-Link LIVE-R User Manual regarding
clock source selection. HOWEVER, when operating in this mode there will be a degradation of jitter performance and
redundant-processor systems may experience a slight delay and/or drop of audio whilst the unit re-references to its backup
MADI stream.
Refer to Appendix page 4-16 for the full list of supported sync frame rates
