Adastra 12x EC36V Ceiling Speaker with US90 Amplifier Package

The Adastra 12x EC36V Ceiling Speaker with US90 is designed to enable the installer to add sound for corridors, washrooms and smaller areas. US series slave amplifiers can be rack mounted in pairs or easily fixed to a wall or under a worktop and can accept the 100V speaker feed as a signal input. Simply connect the 100V input of the US slave amplifier to the last speaker in line as if it was another speaker and then power the mini ceiling speakers from it. Using lower tappings, more speakers can be addded to the amplifier, provided that the total combined speaker Watts is <90% its max output power.
