posted June 9 2014 13:00.05 by spic0m

This is high quality stereo digital audio amplifier with PLL synthesized FM radio receiver. Some of the high level specifications of this receiver are listed in below:

Audio output power: 4W + 4W (with 8ohm speakers)
Input sources: FM and 3 external stereo line inputs
FM frequency range: 88.00MHz 13 108.9MHz
Supply voltage: 12V 13 15V (2A current source is recommended)
Tone control options: Bass, Treble and Loudness control
Bass / Treble boost: 14dB
Bass / Treble cut: 14dB
Station memory: Preset 10 FM radio stations
FM tune options: Auto and Manual with 25 kHz steps

Key components of this audio system are ATmega32A - 8bit microcontroller, TT502 (TEA5767) stereo FM radio module, PT2314 audio processor and ;CPC2002 audio power amplifier. This system is design to work with 12V - 15V (2A) DC power source and KA7632 multi-output regulator is used to manage power requirements to the above mentioned components.
