Slight Delay in Shipping: We wanted to give y’all a quick update on the shipping status, as we know we said we’d be shipping by end of July. So here it goes…
The last thing we do before final assembly is apply something called conformal coating to areas of the circuit board that need protection — in particular, spots where components for SVT’s circuits are placed (if you catch my drift *wink wink*). We should have received the coating material by mid-last week, but it was a no-show. After calling the distributor, we found out they were out of stock, and our order had been put on hold (of course NOW they tell us, right?)! So we scrambled to find another distributor who had it in stock, and it should arrive Mon or Tues this week (Aug 3rd). As soon as it arrives, we’ll start gooping up the parts, but they’ll take at least 24 hrs to dry. So we’re shooting for Thursday (and absolutely no later than Friday), for first shipments to go out.
We’re really really sorry everyone, and we hope you can forgive us!
Circuit Board Manufacturing: First production samples turned out great upon initial review! We have taken them back to the lab for further evaluation while our manufacturer completes production on the remaining ZOs.
On Monday, our manufacturer will begin setting up the line and manufacturing the top side of the circuit board. Tuesday, Paul and I will be on-site to inspect the initial build, inspect the manufacturing for the bottom side, and (best of all) get to power up and listen to the first official ZO FS fresh off the line!
Over the weekend, Paul also built a fixture so we can quickly and easily program the microprocessors and test each board after they’ve been assembled.

Differences Between ZO FS and ZO FS+
We’ve had a few of you ask what the differences are between ZO FS and ZO FS+, so hopefully this will help clarify. The ZO FS+ has an additional transparent amplifier built to the same specifications as ZO FS (i.e., output impedance, power output, etc.). You’ll be able to easily go between the transparent amp and the SmartVektor amp with the push of a switch. This feature is similar to the bypass function we had on the original ZO, but without there being a difference in volume or any pop/clicks. But the biggest benefit is that you’re getting 2 amps in 1 small package!
Size Difference Between ZO FS and ZO2
If you’re interested in the size of ZO FS compared to ZO2, we took some pics we’d like to share:
Preliminary Testing Results
Today (6/17) we ran some preliminary tests on the ZO FS+ engineering sample. We’re happy to report that channel balance was spectacular: within 0.06 dB @ 100mV/1kHz!
