The Soncoz QXA1 is both a headphone amplifier and a preamplifier, supported by a high quality balanced architecture, using components selected for their performance and their ability to provide a pure and accurate sound reproduction. It includes a volume control based on a MUSES 72320 chip and a resistor ladder circuit, ensuring a very low level of noise and distortion, four OPA1642 and four OPA1622 AOPs, ELNA capacitors and a power supply regulation using TPS7A4700 and TPS7A3301 chips. A nice orange LED display clearly shows information about the device parameters.

Moreover, the QXA1 benefits from a complete connectic. It has both balanced XLR and single-ended RCA inputs. On the output side, we find RCA for the pre-output, as well as balanced XLR 4 pins and single-ended Jack 6.35mm for the headphone outputs. The power supply is done in 5VDC via a simple USB-C port.
