Note *. Color Input signal consists of 50mVp−p burst portion and 100mVp−p color portion, treated as
0dB levels (frequency = 3.579545MHz ± 5Hz)
Note 1. ACC control range is the input level when color output voltage is decreased by 3dB,
compared with color output voltage which occurs with a 0dB color input signal.
Note 2. Color portion frequency = 3.50MHz.
Note 3. For color signal output voltage of 0.5Vp−p
Note 4. For color signal output voltage of 0.3Vp−p
