Note 1. Measurement made with 200mVrms Standard Multiplex Composite Signal Containing Left  
(45%) and Right (45%) audio information with a 10% (19kHz) pilot signal. Modulation fre-  
quency is 1.0kHz unless otherwise specified.  
Note 2. Referenced to 1.0kHz output signal with Standard Multiplex Composite Input Signal.  
Note 3. Referenced to 1.0kHz output signal with either Standard Multiplex Composite or Monoaural  
Input Signal.
