It is now widely accepted that one of the essential requirements for high quality digital recording is a first class, high stability master clock generator. These can be complicated devices with many added features, which although useful, may be surplus to requirements. The aim of M-Clock Lite is to provide a simple, high quality clock generator, which is forward compatible with high speed clocks predicted for the future. M-Clock Lite features an AES Grade 1 master clock generator, meaning that the generated clock has a long term frequency accuracy of +/- 1ppm.
