The 503 Power from Lindell Audio is an aluminum chassis for hosting and powering up to three, 500 series modules. Delivered at an extremely attractive price point, the housing dispenses with any unnecessary frills while still delivering a fully professional product.

The unit itself has a universal power supply that in turn delivers a total of 2.4 amps of power to the modules. Overload and short circuit protection is offered, as are gold-plated Neutrik XLR input and output connectors. And for travelling from gig to gig, a neoprene bag is included for protection.
