NPC true analog design and processing capability results in low noise, accurate audio processing for both attenuation and amplification. Digitally controlled analog attenuation for EVR assures no loss in audio resolution (bits) at normal and low sound levels as occurs with digital attenuation methods. NPC headset amplifiers with volume control provide high quality performance for both wired and wirelss headphones. Class D amplifiers provides efficient quality audio output for cell phones and portable devices.
