Grimm Audio CC1 Master Clock

The Grimm Audio CC1 Master Clock is the lowest jitter Word Clock generator and distributor available, providing 16 super high quality Word Clock outputs.  The CC1 can slave to incoming Word Clock and distribute the resulting dejittered Word Clock signal.  The CC1 can slave to incoming AES/EBU and pass through a reclocked/dejittered AES/EBU signal, providing an ultra-low jitter digital source for feeding your favorite D/A converter.

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.
