digital to analog converter for superior CD sound quality.
MOSFET Amplifier: The KD-A525 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
CEA2006 Compliant: The power specifications for the KD-A525
are compliant 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 manufacturers. The power output specs for the KD-A525 are as follows:
- CEA2006 Specs: 20 watts RMS x 4 channels (at 4 ohms,
20Hz-20kHz, 1% THD-N)
- Maximum Power Output: 50 watts x 4 channels (200 total
Amplifier Gain Control: When you
are using the KD-A525 with factory speakers (or those rated to less than 50
watts peak), the Amplifier Gain Control can limit the amount of power being sent
to those speakers. When the Amp Gain Control is set to "low," the volume control
ranges from 0 (minimum) to 30 (maximum). When using speakers rated higher than
50 watts peak, you can set the Amp Gain Control to "high," and the volume
control will range from 0 to 50.
Volume Adjust: The input level of each source (other than FM) is
adjustable relative to the FM radio volume, so there isn't a significant volume
difference when changing sources. Each source is individually adjustable from -5

level. You can turn this feature on or off.
2.5V/6CH Preamp Output: The KD-A525 is equipped with three
pair of 2.5V preamp outputs (Front/Rear/Subwoofer). The front & rear preamp

low frequency signals are cut off from your system's front & rear speakers.
- Low-Pass Filter: The unit's subwoofer preamp output
features a low-pass filter. In order to prevent high-frequencies from being
sent to your system's subwoofers, you can set the cutoff frequency of the
low-pass filter to 55Hz, 85Hz, or 120Hz.
Subwoofer Level: You can adjust the KD-A525's subwoofer
