CC1v2

$2,845 MSRP

The CC1v2 is Grimm Audio's flagship master clock and AES/EBU reclocker, built around a radically redesigned discrete crystal oscillator circuit and a deliberately slow, ultra-stable phase-locked loop. It offers 16 word-clock outputs across two independently configurable groups plus a reclocked AES3 output, making it a reference-grade hub for synchronizing multi-device digital playback and mastering systems.

Specifications

Price: $2,845 / £2,250 inc. VAT
Other i o: AES3 output (XLR) that reclocks and can pass through an AES3 reference input; external word-clock BNC input
Oscillator: Custom discrete crystal oscillator circuit; 125 separate elements tested during construction
Sample rates: Internal 44.1 kHz or 48 kHz base rates with independent ×1/×2/×4 multipliers per output group, up to 192 kHz
Jitter suppression: 90 dB suppression of external-reference jitter at 10 Hz, improving at 60 dB/decade beyond that
Word clock outputs: 16 × BNC (12 in group one, 4 in group two), switchable 25Ω or 75Ω impedance
Reviewer assessment: "There is no doubt that the CC1 is a very stable and highly accurate master clock, even when slaved to external references"
