INTRODUCTION
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 re-sampled and syncronised
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.
Features:
M-Clock Plus has an external word clock input and an AES11 input which retrieves the clock from an AES
audio signal.
Each sample rate converter has selectable AES, SPDIF or TOSLINK inputs, with simultaneous AES, SPDIF
and TOSLINK outputs. This allows many possibilities for format conversion as well as sample rate conversion.
Sample rate converter #2 has inputs on the front panel for easy access.
User selectable word length of 16 or 24 bits with automatic dither generation - particularly valuable for 16 bit
word lengths at low signal levels.
10 word clock outputs - 8 at the rear and 2 at the front for easy access.
