* The Yamaha C-4 is the preamp to the power amp M-4, it's build quality is very good, everything is metal and sits right where it should. The button lights usually don't fail, meaning you don't have to replace them often, in most cases I think these units still have the orginal lights. The phono preamp is excellent and the sound control options are definitely enough. Very practical are the two pre-outs for two power amplifiers. The preamp is very heavy, which again speaks for its good workmanship. The C-4 gets quite warm when it is in operation, which according to oral tradition is due to a Class-A circuit. Conclusion: The Yamaha C-4 is highly recommended and is an excellent match for the M-4 and M-2 power amplifiers.

== Berichte ==
 
Der Yamaha C-4 ist der Vorverstärker zur Endstufe M-4. Seine Verarbeitung ist sehr gut, alles ist aus Metall und sitzt genau da wo es sein sollte. Die Beleuchtung der Tasten fällt in der Regel nicht aus, d.h. man muss sie nicht oft ersetzen, in den meisten Fällen denke ich, dass diese Geräte noch die orginalen Lämpchen haben. Die Phono-Vorstufe ist excellent und die Möglichkeiten der Klangreglung sind auf jeden fall genug. Sehr praktisch sind die zwei Pre-Outs für zwei Endstufen. Der Vorverstärker ist sehr schwer, was wieder für seine gute Verarbeitung spricht. Der C-4 wird recht warm, wenn er in Betrieb ist, was laut mündlicher Überlieferung an einer Class-A Schaltung liegen soll. Fazit: Der Yamaha C-4 ist sehr zu empfehlen und passt hervorragend zu den Endstufen M-4 und M-2.

  • The Yamaha C-4 is the preamp to the power amp M-4, it's build quality is very good, everything is metal and sits right where it should. The button lights usually don't fail, meaning you don't have to replace them often, in most cases I think these units still have the orginal lights. The phono preamp is excellent and the sound control options are definitely enough. Very practical are the two pre-outs for two power amplifiers. The preamp is very heavy, which again speaks for its good workmanship. The C-4 gets quite warm when it is in operation, which according to oral tradition is due to a Class-A circuit. Conclusion: The Yamaha C-4 is highly recommended and is an excellent match for the M-4 and M-2 power amplifiers.
