FURMAN The M-8Dx is the premium power conditioner in the Merit Series, offering a complete power management solution. It includes all the features of the M-8Lx: nine outlets, a 15-amp rating, standard surge protection, noise filtration, and two dimmable, pull-out light fixtures. What sets the M-8Dx apart is the addition of a bright red, three-digit LED voltmeter that displays incoming voltage. This feature allows you to monitor the AC power from your wall outlet, which is especially useful in bars, clubs, and other venues where power can be unreliable.
