DSP Tuning

This technology precisely tailors the audio signal to each speaker based on the unique interior acoustics. Utilizing a Digital Signal Processor (DSP) tuning technology is like having a computer inside the amplifier. The DSP precisely tailors factors like equalization and signal timing to provide a clear and accurate sound stage.

Discrete MOSFET Sub Channel

Provides incredible "instantaneous" power for clean PUNCH bass sound. Discrete MOSFET Subwoofer Channel output circuits provide incredible "instantaneous" power, and is an important key to creating the powerful and clean PUNCH bass sound.
