A High-stability Master Clock and Dual Sample Rate Converter. The M-Clock Plus is a high stability master clock generator offering clock rates from 44.1 to 192kHz, coupled to two sample rate converters, which allow material to be simultaneously re-sampled and synchronized to the selected high precision clock.

In addition to the internal clocks, M-Clock Plus can sync to either external word clock or clocks from AES/EBU signals. Precision clock frequency measurement and display indicates the exact frequency of the selected clock, whether internal or external, to an accuracy of 2ppm.

Ten word clock outputs

The M-Clock Plus has a total of ten word clock outputs, so it’s ready to handle even the most complex systems. Eight outputs are located at the rear and two are on the front panel for convenient access.

Various format and sample rate conversion possibilities

M-Clock Plus has an external word clock input and an AES11 input which retrieves the clock from an AES audio signal. Plus, each sample rate converter has selectable AES, SPDIF or TOSLINK inputs, with simultaneous AES, SPDIF and TOSLINK outputs for many format and sample rate conversion options.

Convenient display information

The M-Clock Plus’ precision clock frequency measurement and 16 character blue LCD display indicates the exact frequency of the selected clock up to 768 kHz, whether internal or external, to an accuracy of 2ppm or 2 microseconds. Display modes include ppm, ±ppm & % pull up/down for video users.
