AM/FM Stereo Mate (120-0103) Specifications Faxback Doc. # 9986 Stereo headphone impedance: 32 ohms. Output readings are taken across a non-reactive load. Output reference level is 0.5 mW total power. The generator output terminates in an IRE loop with the loop pointing toward the back of receiver.

All units should be able to approximate these - some will exceed and some may drop slightly below these specs. Limit specs represent the absolute worst condition that still might be considered acceptable; in no case should a unit fail to meet limit specs. (LB/all-03/06/95)
