Low noise + Low distortion

Ultra-low noise and distortion technologies result in a wide dynamic range (120dB) and a distortion of only 0.004% at output amplitudes greater than 1Vrms, ensuring high performance operation.   Low noise + Low distortion

Advanced switch utilized for reduced popping noise

Combines the smoothness of a potentiometer volume with the precision of a resistance ladder volume for silent volume adjustment with no popping noise.   Advanced switch utilized for reduced popping noise

Built-in amp features flat frequency characteristics up to 100kHz

The built-in high slew rate amp features linear output characteristics at up to 100kHz, enabling high fidelity audio playback - even with DVD players.   Built-in amp features flat frequency characteristics up to 100kHz
