Dorrough Model 1200 Analog Stereo Signal Test Set

The Dorrough Stereo Signal Test Set, Model 1200, is a simple and easy-to operate gain set that will allow you to quickly monitor and dynamically balance stereo broadcast lines. The Model 1200 offers the widest range ever designed for accurate measurement of level, balance, crosstalk, and signal-to noise of your system from noise floor to signal clipping. Now you can easily verify stereo system performance without having to call for an oscilloscope or DVM from the maintenance shop. Yet if incorrect conditions are spotted, just connect test equipment to one of the Monitor Jacks to examine a suspected problem in detail.

Barrier strip and parallel XLR connections, with an “audio loop-thru” feature, are included to provide installation flexibility. Input impedance is set at 40k Ohms to insure stereo program monitoring without any loading effects. Rack-mountable.
