JBL ProCoustics MS-2 – Car Audio Optimiser

A digital signal processor in a small box with a really simple user interface. Designed to “Get better sound from your portable music player” as it is added to your car’s OEM system, it takes the signal via 3.5mm headphone-out socket from your phone, iPod, whatever, to feed in turn to the JBL MS2 before sending it onwards to the car’s auxiliary stereo input. The device makes two tone bursts through your system and ‘listens’ on its own built-in microphone before setting up a DSP algorithm for your listening space and your position within it.
