Notes
1. Guaranteed for mono, mono + pilot and stereo.
2. Adjustable.
3. S1 closed; reference: AF output voltage f = 1 kHz (mono).
4. Intermodulation suppression (Beat-Frequency Components (BFC)):
α2 = V---V--o---o(--s-(--ps---ui-g--r-ni--o-a--u-l-)-s--)---(--a-(--a-t---t-1---1--k---kH---H-z---z-)---)- ; fs = ( 2 × 8.367 kHz) – fH
α3 = -V--V--o--o-(--s-(--sp--i-u-g--r-ni--oa---ul--)-s--)(---a-(--a-t---t-1--1---k--k-H--H--z--z-)---)- ; fs = ( 3 × 10.823 kHz) – 2fH
measured with 100% modulated input signal: L = R; pilot signal = 200 mV p-p; fm = 8.367 or 10.823 kHz.
