Grimm Audio CC1v2 Master-Slave Clock

The Grimm Audio CC1v2 is a master-slave clocking system designed to deliver world-class timing stability and ultra-low jitter performance to every device in your studio. Capable of operating as a master clock or slaving to external word clock and AES3 inputs, the CC1v2 distributes pristine sync signals across up to 16 outputs. By leveraging Grimm’s radically redesigned discrete crystal oscillator, the CC1v2 achieves stability surpassing even the best laboratory-grade test equipment, ensuring digital audio systems gain the ultimate in musical timing, tonal stability, and imaging precision.

Developed from extensive research into the effects of jitter on sound quality and emotional perception, the CC1v2 focuses on achieving maximum stability rather than simply reducing jitter figures. A powerful PLL circuit provides an astounding 90 dB of jitter suppression at 10 Hz, with further improvements at 60 dB/decade. Supporting base rates of 44.1 kHz and 48 kHz with 1/2/4 multiples in separately selectable groups, the CC1v2 also includes an AES/EBU reclocker to clean digital signals before conversion. Built with Grimm Audio’s characteristic attention to detail and solid design, the CC1v2 is an indispensable tool for mastering, mixing, and high-end digital playback systems.
