Your Product Guide

👍 T'ang-ku-la Module ▶️ The T'ang-ku-la Module features a novel three-stage feedback circuit. This innovation significantly reduces noise and high-frequency distortion, boosting the dynamic range to an impressive 147dB. The advanced technology also minimizes heat generation, thus enhancing reliability and extending the lifespan of electronic components while reducing thermal noise.

👍 Ground Loop Noise Disappearing Magic ▶️ When multiple devices are connected, ground loop noise can cause issues. The A70 Pro includes a GND/LIFT switch. Activating LIFT mode eliminates ground loop noise effectively.

👍 Precise Volume Control with Relays ▶️ The A70 Pro employs relays and resistor networks for a high-precision volume control system. This R2R design ensures long-term reliability and accuracy, even at low volumes, providing a consistent listening experience.

👍 A Versatile Amplifier and Preamp ▶️ The A70 Pro excels as both a headphone amplifier and a preamplifier. It matches the performance of a dedicated headphone amp mode, with a low output impedance of 50Ω for RCA and 100Ω for XLR. This design allows it to be compatible with a wide range of input impedances, making it suitable for various power amplifiers. Additionally, the full-featured remote control simplifies operation.

👍 Expandable Inputs ▶️ The A70 Pro offers one set of balanced XLR and one set of single-ended RCA inputs. With the Ext90 input expansion, you get four balanced XLR and two single-ended RCA inputs, providing even more connectivity options.
