With this amplifier, you can run your front speakers with the front channels (A), then combine the rear channels (B) to drive a subwoofer. You can also put this versatile amp into 2-channel mode to send up to 300 watts RMS each to a couple of component speakers or subwoofers. The front channels have a variable high-and low-pass filters to adjust the sound for front sound staging or a finely tuned bass. Switchable high and low pass filters on the rear channels to enhance the full-range speakers. Speaker-level inputs allow you to add this amplifier to a factory system. This Class D amplifier is CEA-2006 compliant.

High Quality Sound Parts and Tuning

Audio film capacitors and low-impedance coil are used for the output LC filter to ensure excellent sound quality. Audio tuning based on the reproduction of the original audio source allows everyone to experience the difference in sound quality when connected.

High-capacity Audio Power Source Capacitor

Pioneer's original high-capacity audio power source capacitor contributes to higher sound quality and stable power allotment even at high output.

Variable HPF & LPF

Adjust LPF & HPF (40-500 Hz).

Bass Boost Remote

Bass Boost (Remote) for optimal bass level adjustment according to listening preferences and music characteristics.

Automatic Signal Sensing and Turn-On

Pioneer's Class-D amplifier automatically selects an input signal mode between the RCA level and the speaker level detecting an input signal. In the case of speaker line input, the amplifier will automatically switch on when the receiver is turned on.

Protection Control System

Designed to bolster reliability, this system reduces the risk of damage due to an overly high input power, by sensing the internal temperature and moderating the signal on-the-fly.

Class FD Technology

Enjoy first class sound and powerful volume on a versatile system at half the size of other units.
