Alpine PDX-4.150
In the PDX-4.150, Alpine met the challenge of producing a full range digital amplifier to rival the sound quality of even the best high-end Class A/B amplifiers. They use improved feedback circuitry to faithfully reproduce the input signal for improved dynamic range and higher fidelity. A revolutionary power supply filtering system, lower switching frequencies and lower output impedance combine to create extremely low distortion and greater speaker control, for clarity that meets or exceeds that found in the best Class A/B amplifiers.
