Audio & Tuner Section
MOSFET Amplifier: The Dual XR4120 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
XR4120 are as follows:
- CEA2006 Specs: 16 watts RMS x 4 channels (at 4 ohms,
20Hz-20kHz, 1% THD-N)
- Maximum Power Output: 60 watts x 4 channels (240 watts

with the CEA2006 Mobile Amplifier Power Testing and Measurement standards from
the Consumer Electronics Association (CEA). These standards were developed as a
way to equitably compare power specs from model to model and between
