The Drawmer D-Clock is a dual-function unit that serves as both a word clock distribution amplifier and a precise word clock measurement device, designed for use in digital audio environments. Housed in a 1U rackmount chassis, the D-Clock provides a clear and detailed readout of incoming word clock signals, displaying both frequency and sample rate in real time. It accepts word clock inputs from either BNC or AES/EBU sources and converts them into a cleanly buffered signal, which is then distributed across ten BNC outputs.
At the heart of the Drawmer D-Clock’s design is its ability to help engineers and technicians verify the presence and stability of a word clock signal, a crucial aspect in digital studio setups. It offers accurate frequency measurement to a resolution of 1Hz and displays standard digital sample rates, including 32kHz, 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz and 192kHz. The Drawmer D-Clock can also display the corresponding frequency in kilohertz to assist in identifying non-standard or drifting clock sources.
In distribution mode, the Drawmer D-Clock regenerates and reshapes the incoming word clock signal for clean and reliable transmission to multiple devices, reducing jitter and maintaining synchronisation integrity throughout the digital signal chain. Its 10 BNC outputs are divided into two isolated groups of five, allowing flexibility in routing clock signals to separate sections of a studio setup. Additionally, its dual inputs allow for source selection between two different clocks, with front panel switching.
An LED display provides an instant view of the input clock frequency, and the unit offers warning indicators for signal loss or instability. This makes it not only a distribution device but a diagnostic tool for studios that demand high reliability and precision in their digital synchronisation.
The Drawmer D-Clock is engineered with the same commitment to audio integrity and build quality that has characterised the brand for decades, making it a dependable component in professional digital audio environments.
