QXA1 continues SONCOZ’s family-oriented design with the same dimensions as QXD1.
QXA1 and QXD1 Stack In Combination
QXA1 is the perfect companion of QXD1 DAC, they not only have similar performance and appearance, but also are the gold combination of DAC&HPA.
Analog Input and Output Interface
QXA1 supports freely selected balanced(XLR) or single-ended(RCA) analog inputs and PRE single-ended(RCA) analog outputs.
QXA1 supports HPA balanced(BAL: 4-Pin XLR) and single-ended(SE: 6.35mm) analog outputs.
Multi-function Knob Button
QXA1 has one multi-function knob button which integrates all the functions and operations. Operation mode include one press, long press and slow and fast left or right rotation.
How to select HPA BAL output:
Press the knob once and rotate it left or right until the “OUT” indicator flashes, press the knob again and rotate it left or right until the “BAL icon” flashes, then press again and the HPA BAL output setup is completed.
Press the knob once and rotate it left or right until the “OUT” indicator flashes, press the knob again and rotate it left or right until the “BAL icon” flashes, then press again and the HPA BAL output setup is completed.
Menu Level
QXA1 contains two levels of menu：“IN”, “HPA”, “PRE”, “V”and “G” are the five first-level options and their corresponding second-level options are as follows：
- IN (Analog inputs): RCA and XLR icons
- HPA (Headphone outputs): SE and BAL icons
- PRE (Pre-Amp outputs): Enable and Disable setting
- V (Volume): Volume value digital display
- G (Gain): Gain value digital display
Volume and Gain Adjustment
QXA1 integrates MUSES 72320 electronic volume which performs low noise and low distortion characteristics and with resistance ladder circuit.
Volume: 0.5dB/Step in the range of -99.5 ~ 0dB
Gain: 0.5dB/Step in the range of 0 ~ +12dB
The volume and gain value of each combination of input and output can be memorized independently and won’t be lost when the power goes down. QXA1 also supports volume fade in fade out like SGA1.
Gain: 0.5dB/Step in the range of 0 ~ +12dB
The volume and gain value of each combination of input and output can be memorized independently and won’t be lost when the power goes down. QXA1 also supports volume fade in fade out like SGA1.
Fade In Fade Out
When the knob is setting menu options, QXA1 will first mute(fade out) the output. After the adjustment is completed then output enable(fade in) and it also continues the features of SGA1.
Mute Output and Stand By
When QXA1 is working properly, press the knob button once will MUTE the QXA1’s output and the first-level options “V” will flash. After about 40 seconds the screen will gradually dim. Long press the knob for 3 seconds to enter standby, then the screen is off.
Screen Saver and Reset
When QXA1 is used normally, the brightness of the screen will gradually dim after about 40 seconds without any operation of the knob button, which reduces light pollution while extending screen life.
QXA1’s system can be reset in the same way as SGA1’s: Long press the knob button about 6 seconds will reset QXA1.
Software-controlled POP Free
Relay delay output circuit is added to the output of HPA and PRE to achieve POP free by software delay which is more stable and reliable than the RC delay of hardware.

A1: Yes. When the HPA is outputing, the PRE output can be enabled or disabled.
Q2: How to adjust the volume quickly?
A2: When the QXA1 detection knob is turned rapidly, it will automatically enter the mode of rapid volume adjustment, and when it is detected that the knob is turned slowly, it will enter the mode of fine adjustment.
Q3: Is the gain continuously adjustable?
A3: Yes. Gain is adjusted by 0.5dB/step.
Q4: What is the power supply for QXA1?
A4: The QXA1 can be powered by a linear power supply/a mobile power supply/an adapter with output specification of 5V@2A.
Q5: How to make QXA1 enter standby mode?
