Category: Main -> Mk. Two


empeg car Mk.2

The Mk.2 player was born from the necessity of improving production rates by redesigning for near-100% surface mount components and introducing an automated circuit test rig. We couldn't bring ourselves to produce a new revision without introducing some new features, and the creeping feature creature was soon at work! The new player received an improved audio stage, 10BaseT Ethernet (we couldn't do 100Mbit due to a lack of DMA), display dimming, more memory, microphone input (for future Voice Recognition support), rotary front panel control, improved docking and a stylish new look. The tuner was moved out to an external module, partly to improve isolation from the noisy processor bus and partly to facilitate future upgrades for digital radio.

Manufacturing Pics

The empeg car was manufactured by contractors in the UK, using a state of the art automated production line. We were set to produce around 1,000 units per month with the option to increase this if necessary. In fact it was not necessary!
