Power Connection
Power supplies for the console are fitted to every bay of 24 channels. The Centre section does not have its own supply
as it receives its power from the bay to its left.
A 24 channel console has a single power input, a 48 channel console will have two input leads, a 72 channel console will
have three and a 96 channels console has four. The leads supplied are 2m.
It is important that all of the mains leads are connected to the same supply source so that they are all switched
concurrently. Power input to each section is via IEC plug. Refer to the diagram on page 14.
1. Locate the two (three or four) 2m IEC input leads and attach to the console in the locations indicated opposite.
2. Run each mains lead along the underside of the cable trays and secure with cable ties (holes are provided) – this
will keep the power cables separated from the audio cables.
3. Route the lead for each section down the middle of the nearest console leg.
4. Terminate each lead at a suitable outlet located near or beneath the console legs.
PSU Redundant consoles
Consoles fitted with redundant power supplies have two separate PSU systems fitted to each channel bay; each section is
therefore equipped with two mains input connectors. For complete redundancy, It is recommended that one of the
supplies should be fed from an uninterruptable source.
UPS Provision
Where either the primary or backup supply of mains power is provided from an uninterruptable source (UPS) the
output waveform of the UPS equipment must be of the sinusoidal variety. Switched or stepped output waveforms may
cause damage to the console power supplies so must not be used.
