The heart of any disc player is the transport mechanism itself. But what do you do if current mechs simply aren’t up to the job? If you are CH Precision, you build the CH Precision D1.5! The carefully selected optical pick-up and motor are precisely mounted on a massive brass sled that weighs almost 1kg (2.2lbs). This high-mass lowers the mechanical resonance frequency of the module several orders of magnitude lower than in most other transports, while ensuring an ideal counter-weight to the torque of the spinning disc. The critical mechanical parts of our proprietary Mechanically Optimized Reading System (MORSe) are built entirely in-house.
The complete module is isolated from the rest of the chassis using four alpha-gel isolators, fine-tuned to filter vibrations all the way down to AC mains frequencies. This prevents vibrations generated by the spinning of the disc from reaching sensitive electronic boards, as well as low frequency vibrations originating in the power supply or chassis disturbing the accurate tracking of the laser mechanism.
