A few weeks ago I posted about the Switronix PTC-A7S Coiled Powertap Cable short circuiting inside of the Sony A7S. Switronix reached out immediately to examine the damaged cable and figure out the source of the malfunction. After running a series of tests – voltage, surge, runtime – the PTC-A7S passed all of them.
Once they shipped the new cable, I had some downtime to test it out at NAB and discovered that the Tilta Hyperdeck Shuttle distributor plate bypassed the on/off switch when both a D-Tap and 12V cable were plugged in simultaneously. This led us to believe that there was a freak, surge of voltage that happened when the Tilta Hyperdeck Shuttle plate sent power to the Switronix PTC-A7S dummy battery even though the switch was off. This was confirmed by Tilta when we visited their booth and demonstrated the glitch.
So shout out to Switronix for their patience with my freak out and super customer service – from testing the cable to also performing on-site quality control at their NAB booth. For the rest of the convention, the PTC-A7S D-Tap Cable performed flawlesly, providing hours of uninterrupted power with the Atomos Shogun. Look for more NAB 2015 coverage when we speak to Switronix about their new HyperCore Li-ion batteries and VoltBridge app. Stay tuned!
