GFT-555II
For serious music lovers, the quality of FM stereo is often unacceptable except as background music. Adcom's GFT-555II tuner confronts these inadequacies directly and brings in FM broadcasts that sound as good as the transmitted signal allows.
Adcom designers have done everything possible with the GFT-555 II to reduce noise and distortion (the major enemies of FM reception) to a minimum. The new low-loss printed circuit board minimizes signal degradation. Laboratory grade component parts, including 1% Roederstein metal-film resistors and metal film capacitors in all critical areas, assure outstanding performance and maintain their quality for extended periods of time.
Superior FM performance directly results from an improved RF (radio frequency) section with high resistance to overload, excellent image rejection characteristics and exceptional signal-to-noise capabilities. The critical IF (intermediate frequency) section boasts new "symmetrical skirt" ceramic filters for improved selectivity. High blend and mono modes allow relatively noise-free reception of even the weakest FM signals.
Buffered, low impedance class A outputs insure optimal operation of the multiplex circuitry for maximum channel separation regardless of the "load" imposed by cable or control center anomalies. A rear panel switch provides precise level matching for compatibility with other source components.
In keeping with typical Adcom tradition, convenient features abound. The front panel is simple and uncluttered. Tuning is easy with 16 programmable presets (8 FM/8 AM) and an FM Scan mode in addition to step tuning via Up and Down push-buttons.
Listen to a good FM broadcast on the GFT-555II and you'll hear why Adcom stereo components are so critically acclaimed. Once again, it's in the details.
