Although the internal circuitry does not require this much depth, keeping the depth of the unit the same as the amplifiers allows for easier wiring and mounting. All connections are made at the rear panel of the unit. There are eight sets of input and output screw terminal load connectors. The load lines actually pass through the unit via these connectors. Internal current transformers are used to sense the current passing through each of the eight channels in the unit.
Voltage is sensed with high impedance differential amplifiers across the transformers.
Also located on the rear panel are Crown Bus data loop connectors, aux port input and output terminals, balanced signal generator output, and a fused speaker monitor output. User Labels - Two general labels and one label per test channel. Viewing Curves - From software you may recall curve information and display it on screen for visual analysis. Screen plots may be printed or saved to file. Data LED - Flashes to indicate presense of data communication, may be forced on via software.
