Drawmer D-Clock-R

Designed for Live & Broadcast Environments

Expanding on the renowned D-Clock in providing word clock measurement and distribution, the D-Clock-R has been developed with not only studio recording in mind but also the live and broadcast environment, where reliability and stability are absolutely imperative.

Designed for fail-safe operation the D-Clock-R incorporates dual redundancy for both the power supplies and also the auto-sensing clock inputs, ensuring that the show will go on regardless of technical difficulties.

Features

Dual Redundant Power Supply via 2 x universal voltage filtered mains power inlets for continuous operation & reliability.

The D-Clock-R is fitted with two identical and independent power supply units, providing Dual Redundancy. In situations where it is critical that power must be maintained the load is shared between the two supplies, however, should power to one fail the D-Clock-R will still run perfectly well on either.

LCD Display with 3 sample rate measurement modes and accurate to 2ppm.

A 16 character blue LCD display provides a reference measurement of the incoming sample rate to an accuracy of 2ppm and displays the information in three different formats: actual frequency (to one decimal place), nominal frequency +/-ppm error, or nominal frequency plus percentage of pull up or pull down.

Auto-Sensing Dual Redundant WordClock/AES3id BNC Inputs provide continuous operation and added dependability.

Two inputs are provided, a default and auxiliary, capable of locking on to both word clock and AES-3id, with the source automatically selected depending on the type and quality of the signal. Twelve BNC clock outputs are situated on the rear panel with a further four on the front panel for quick patching to other digital devices.
