How to choose the best synchronizers and clock generators
Clock Stability
This is the big one. Jitter is the enemy - a stable clock minimizes it. Look for specs around <10ns jitter for serious work, though even 20ns can be acceptable for bedroom studios.
Word Clock I/O
The more options, the better. BNC is standard, but AES/EBU and S/PDIF connectivity broaden your compatibility with older and newer gear.
Glitch-Free Switching
When syncing multiple devices, a clean transition is critical. Glitches can ruin takes and mess with your timing.
Feature Set
Beyond basic clocking, consider things like selectable sample rates, LTC/MTC support for film work, and the ability to generate test tones for calibration.
Build Quality & Reliability
A flimsy unit that dies mid-gig is useless.
Buying guide
Okay, so you need a solid clock source but your studio budget isn't overflowing. It's a common problem. A sloppy clock can introduce jitter and phase issues that'll make your mixes sound muddy and your tracking sessions a headache. Let's find you something that'll keep everything locked without breaking the bank - we're aiming for serious functionality under $2000.
At this price point, you're making compromises somewhere. Often, that's in the sheer number of I/O options or the complexity of advanced features. Don't get hung up on fancy displays - a clean, stable clock is far more important than looking pretty.
If you're gigging, prioritize something rock-solid and portable; if it's a studio-only situation, you can lean towards more features and slightly less ruggedness.

Questions
What's the difference between Word Clock and AES/EBU?
Word Clock is a digital sync signal, primarily for syncing digital audio devices. AES/EBU carries digital audio, but can also be used for clocking - it's less common but provides an alternative connection method.
How much jitter is 'too much'?
Under 10ns is ideal, but anything above 20ns can start to introduce audible artifacts, especially with sensitive gear. It really depends on your ears and the gear you're syncing.
Can I use this to sync my drum machines?
Absolutely! Many drum machines and sequencers rely on external clock. A dedicated clock generator can often provide a tighter, more consistent pulse than the internal clock on those devices.
I'm running a hybrid analog/digital setup - is this still useful?
Definitely. Many modern analog gear pieces have digital clock inputs for synchronization. It helps keep everything in phase and ensures tight, punchy rhythms.
What about USB clocking - is that reliable?
USB clocking can be a bit flaky, especially on older computers. While some units support it, a dedicated hardware clock generator offers superior stability and eliminates potential USB-related hiccups.
