Pioneer F-9


High technology shouldn't be overly confusing, and Pioneer's F-9 FM/AM tuner featuring advanced, yet easy to use technology is the proof.

Controls and indicators include FM/AM IF bandwidth selectors, 6 FM/6 AM preset buttons, an auto / manual search selector, a multipath indicator, a digital frequency readout, and much more.

The FM/AM front end of the F-9 features an important technology - Quartz PLL digital synthesizer tuning. It's Pioneer's answer to the problem of mis-tuning or drift that may occur due to a variety of reasons including varying temperature and humidity.

However, our Quartz PLL tuning system offers even more than accuracy: preset tuning of up to six FM and six AM stations. Once you preset your favourite stations, you can recall each instantly at the touch of a button. Also possible is push button electronic scan-tuning up and down the tuning band.

Often RF (Radio Frequency) intermodulation distortion is created in the front end and mixes with the sound you hear from the station you are listening to, limiting audible dynamic range and causing poor high-frequency response.

The FM front end of the F-9 is essentially free of distortion, because it is push-pull configured using two Pioneer exclusive ID (Ion Implantation Double Diffusion) MOS FETs.

These are two technologies which, together, account for the high signal to noise ratio, low distortion and wide frequency range reaching 15kHz, of the F-9.
