Every Detail You Need

👍 T'ang-ku-la Module ▶️ The T'ang-ku-la Module introduces a revolutionary three-stage feedback circuit. This advanced design drastically reduces noise and high-frequency distortion, pushing the dynamic range to an astounding 147dB, an unmatched new realm. The cutting-edge technology minimizes heat generation, enhancing reliability and extending the lifespan of electronic components, while also reducing thermal noise.

👍 Ground Loop Noise Elimination ▶️ When multiple devices are combined, ground loop noise can become a nuisance. The A70 Pro addresses this issue with an innovative GND/LIFT switch. When facing ground loop noise, simply switching to the LIFT position eliminates the noise completely, ensuring a disturbance-free listening experience.

👍 Precise Relay Volume Control ▶️ The A70 Pro features a relay and resistor network, forming a highly accurate R2R volume control module. This ensures precise volume adjustment, maintaining high fidelity even at whisper-quiet volumes.

👍 Dual Functionality: Headphone Amp and Preamp ▶️ The A70 Pro excels as both a headphone amplifier and a preamplifier. It delivers exceptional sound quality in headphone mode with an RCA output impedance of just 50Ω and an XLR output impedance of 100Ω, making it compatible with a wide range of power amplifiers and input impedances. Additionally, its user-friendly remote control simplifies operation.

👍 Expandable Input Flexibility ▶️ The A70 Pro offers one balanced XLR and one single-ended RCA input. With the Ext90 input expansion, it doubles the balanced inputs to four and adds two single-ended RCA inputs, providing unparalleled flexibility for your audio setup.
