The JBL MS-2 is a small digital processor that optimizes the signal coming from a portable music player to improve the quality of sound playing through car or home audio speakers. Dalas Verdugo shows how the MS-2 works in this video by Adam Lisagor (aka Lonely Sandwich).
The MS-2 uses DSP (digital signal processing) equalization to optimize system performance for the acoustic characteristics of your speakers, electronics and vehicle interior, and DSP time correction to ensure that all the sounds reach your ears simultaneously, creating a coherent, richly detailed soundscape.
