Soncoz QXA1 is both a headphone amplifier and preamplifier, supported by a high-quality balanced architecture, using components selected for their performance and ability to provide clear and accurate sound reproduction. It includes a volume control based on the MUSES 72320 chip and a resistor ladder circuit that provides very low noise and distortion, four OPA1642 op-amps and four OPA1622 op-amps, ELNA capacitors and a power regulator based on TPS7A4700 and TPS7A3301 chips. The pleasant orange LED display clearly displays information about device parameters.
