The "Power Block" is a new USB cable filter similar to the Short-Block, but this one also provides DC power to the device.
The Short-Block could not be used with devices that used the +5V power in the USB cable, but the Power Block can be used with these devices.
The Power Block utilizes Hynes regulation technology and similar filtering to the Short-Block, delivering the best of both worlds. It is ideal for USB interfaces on DACs and USB converters that use the +5V power. These are typically XMOS-based interfaces and usually those with galvanic isolation such as the Berkeley products.
We have tested the Power Block extensively with our galvanically isolated XMOS-Based USB interface and the performance is off the charts.
The Power Block provides a USB input for your cable from the computer and a short USB umbilical cable that plugs to the DAC or USB converter. It is powered from AC and can be configured for 117VAC or 230VAC. Cabinetry is silver with Overdrive-type front-panel. A 14 gauge shielded cord is available to use with it for $16 more.
