Rack Mounting

To enable rack mounting, the front panel of the ADC1 has rack-mount holes that are machined to conform to standard rack mount dimensions. The width of the ADC1 panel is exactly ½ that of a standard 19” panel. The ADC1 is one rack unit high. Either ear of the ADC1 can be mounted directly to a standard 19” rack. A machined junction block connects the other ear to a ½ width blank panel, another ADC1, a DAC1, or other ½ width Benchmark products. When joined, the two units form a single rigid 19” panel that can be installed in any standard 19” rack.
