This rack has a nice overall finish. It shows that in a 19-inch two height units. Electronic side is a well-supplied device where cms is waiting for you ... The device comes with a measurement microphone and also host a pink noise generator that comes in handy. After testing the device with a GBF, the display remains consistent between the signal sent by the generator and that given by the rack. A slight drift however be noted on the amplitude displayed on the ends of the band but really still okay for a device that appears in this price range.
