CC1v2

Grimm Audio CC1

The CC1v2 distributes word clock and AES3 sync signals of superb quality to all equipment in your system. It operates in master mode or slaves to word clock and AES3 inputs. Now, any studio can benefit from a low jitter clock like ultimate musical timing and stability of tone.

“Owing to a radically redesigned discrete crystal oscillator, clock stability betters that of even the best test equipment available.”

Grimm Audio’s extensive research into the correlation between jitter and sound quality brought to light that emotional response to music is vastly more sensitive to jitter than previously realized. Attention turned from “making jitter low” to achieving the most stable clock possible. This research turned up a surprising array of previously underestimated performance factors like power supply noise, oscillator control circuit noise and low-level crosstalk. Owing to a radically redesigned discrete crystal oscillator, clock stability betters that of even the best test equipment available.

To sync to an external reference the CC1 sports a PLL offering an astounding 90dB of jitter suppression at 10Hz, further improving at 60dB/dec. The CC1 offers base rates of 44.1kHz and 48kHz and 1/2/4 multiples in separately selectable groups, in addition to an AES/EBU reclocker for cleaning the digital feed to your DA converter. Like all Grimm Audio products, the CC1 features striking styling and solid build quality.

The CC1 has 16 BNC word clock outputs

Lately I've noticed my system wasn't sounding so great and found my CC2 was accidently turned off. Once I secured the power cord, turning on the unit, I happily noticed how much more vivid, dimensional, and natural everything sounded.
