Может переводчики попутали, и воткнули диапазон частот радио, на FM ? очень похоже, если честно ни разу не встречал, чтобы в мануале писали меньше 20 кГц
Да нет, дело не в переводе, хотя это (50 Гц до 15 000 Гц, суммарное значение
коэффициента нелинейных искажений 5%, на грузка 4 W для обоих каналов)
и переведено не точно, но это и в оригинальном мануале так:
