Product Description


Connect-AC converters are built for fixed-facility and infrastructure use. AC power is built in, which means you just need to connect a standard figure-of-8 cable – no more unsightly external power supply units!

As you might expect from an Atomos-designed smart production tool, Connect-AC converters offer much more than just format conversion. They also include a test pattern generator and audio test tone. They've even included a flashlight mode for use in dark locations!
