TransAudio Group, a Las Vegas-based sales rep, introduced the Drawmer M-Clock Plus. It’s a high-stability AES Grade 1 master clock generator.
M-Clock Plus supports clock rates from 44.1 kHz to 192 kHz, and additionally incorporates dual sample rate converters, allowing material to be re-sampled and synchronized to the selected high-precision clock.
M-Clock Plus can synchronize to an external word clock input or retrieve the clock from an AES audio signal via an AES11 input, in addition to its internal word clocks. The unit offers 10 word clock outputs: eight on the rear connector panel; and two at the front for access when the unit is rack-mounted. The exact frequency of the selected internal or external clock is measured and displayed with an accuracy of 2 ppm.
Access to the two sample rate converters is via selectable AES, S/PDIF or TOSLINK inputs, with simultaneous AES, S/PDIF and TOSLINK outputs, enabling various format conversion and sample rate conversion options. Sample rate converter #1 has a selectable AES, S/PDIF or TOSLINK input on the front panel. The inclusion of automatic dither generation with user-selectable 16- or 24-bit word length is valuable for 16-bit word lengths at low signal levels, according to the company.
