Yamaha anunta cu mandrie introducerea noului preamplificatorului C-5000 in gama lor de produse:
„In pursuit of the intangible musical quality that breathes life into high-fidelity audio, the world’s largest sound company presents the C-5000 pre-amplifier. From the concert stage to the home, Yamaha has drawn on its vast musical history to create an instrument capable of faithfully reproducing every nuance and emotion in the performance.”
Complet balansat
Impreuna cu Pick-Up GT-5000 si amplificatorul M-5000, Yamaha livreaza produse full balansate denumindu-le astfel Premier performance.
C-5000 este un preamplificator cu iesire balansata si circuite discrete. Incepand cu intrarea de semnal pana la iesire, al phono EQ totul este balansat inlaturand influienta ground noise-ului.
C-5000 este capabil de reproducerea cat mai exacta a sunetului datorita dispunerii a doua transformatoare toroidale, unul pentru fiecare canal. Fiecare transformator este integrat intr-o carcasa metalica, placata cu cupru pentru a minimiza vibratia si fluxul magnetic.
Prin integrarea sistemului dual-mono, sunetul este echilibrat, cu o definitie deosebita a frecventelelor joase, avand un sunet aerisit, dinamic, coerent si transparent.
C-5000 a fost gandit ca o piesa din liga suprema a producatorului Yamaha, sa arate foarte bine, finisat excelent insa si sunetul sa fie pe masura.
Potentiometrele, butoanele sunt precise si rigide, spike-urile de atenuare a vibratiilor au fost gandite si implementate atent de producatorul urmarind atat design-ul cat si eficienta in acelasi timp.
