You can store up to 18 FM station presets and 12 AM station presets (manually or automatically). The Local function allows only strong radio stations to be received, blocking stations with weaker signals. You can even switch the tuner between USA or European tuning.
MOSFET Amplifier: The Dual marine receiver is equipped with a MOSFET amplifier. Compared to conventional power supplies, the MOSFET amplification circuit is smaller and more efficient, and it delivers increased power with less distortion and absolutely zero on/off switching noise. More power means louder and cleaner music at higher volumes because you're not pushing the limits of the amplification circuit. The power output specs for the head unit are as follows:
- CTA2006 Specs: 16 watts RMS x 4 channels (at 4 ohms, 20Hz-20kHz, 1% THD-N)
- Maximum Power Output: 50 watts x 4 channels (200 watts total)
