The Drawmer M-Clock is a multiple output master clock generator with four further channels of sample-rate-conversion, all locked to the same master clock. There are also alternative sync outputs for those pieces of equipment without wordclock connections that can be sync'ed via their digital audio inputs using a 'black' signal carrying no audio information.

The advantages of combining wordclock with multiple channels of 'clock-locked' sample rate conversion are significant. With M-Clock, all pro and consumer digital equipment can run in the same system, locked to the same clock, with no worries about finding a suitable sync source. You will no longer have to switch equipment between internal and external sync as you repatch - and the M-Clock's ultra-precision, low-jitter clock helps maintain optimum stereo imaging, lower noise and lower distortion. If you have multiple pieces of digital equipment, whether professional or consumer, M-Clock can be a most cost-effective upgrade.
