Καλημέρα,
στο site της audio technica αναγράφεται το παρακάτω, γνωρίζει κανείς πως βρίσκουμε το output impedance κάθε κεφαλής ή αν αναγράφεται στα τεχνικά χαρακτηριστικά της, ευχαριστώ
"The impedance is a measure of the total opposition that a circuit presents to alternate electric current. The output impedance of an electronic device is the impedance of its internal circuit “seen” by any device connected to its output. The Input impedance of an electronic device is the impedance “seen” by any source connected at its input. Input impedance of the phono preamplifier and output impedance of the cartridge should be properly matched to achieve optimal sound. An impedance mismatch will work as a filter and degrade the sound making it dull or harsh depending on the setup. A general rule of thumb is that the input impedance of your phono preamp (also referred to as the load impedance of your cartridge) should be 10 times the output impedance of your cartridge (also called the source impedance)."
