Staggered Power (Model EC 500.4S): Two separate power supplies with two separate output sections for the front and rear channels.
In essence, it is 2 completely separate amplifiers sharing the same chassis. More power is created on the rear channels to allow the
performance to be delivered where it is needed most.
Strapped Power (Model EC 1200.1D): The Mono Block handling subwoofer speakers sometimes need more power. The following RMS
power can be achieved by strapped 2 amplifiers @14.4V:
