Documents code:AU0001/AU0002/AU0003

LA-QXD1 is a very complete symmetrical digital / analog / DAC interface integrating a combo of SABER ES9038Q2M chips as well as a USB XMOS interface.

Note: 

1.The Power input is DC 5V-1A or you can use power bank.(Which are not included in the package content.)

2.The generation of static electricity can cause damage to the componentsThe easiest way is to contact the shell of the DAC with other grounded equipment.

3.Sampling frequency (Pay attetion to choose the correct input frequency as follows otherwise it will lead to problems!)

USB: 32-bit / 768kHz PCM - DSD512 (native)

Optical: 24-bit / 192 kHz PCM - DSD64

Coaxial: 24-bit / 192 kHz PCM - DSD64

Q2: Power consumption of the whole machine.
A2: <4W.
Q3: What is the impedance of the XLR/RCA output?
A3: XLR output 200 Ω and RCA output 100 Ω.
Q4: Does the LA-QXD1 remember the volume and different filter choices for each input?
A4: LA-QXD1 does not have memory function, it will return to the default state after powering on/off.
Q5: How can I switch between the different filter modes of the LA-QXD1 DAC?
A5: Long press the Mute button for 2 seconds to select the filtering mode, and each long press switches one filtering mode. The switch order is APOD-BRIC-FAM-FAM-FAL-HYER-SLM-SLL.

Q8: How do I determine if the volume of LA-QXD1 is turned up to the maximum?
A8: Press and hold the volume "+" to quickly adjust the volume, and the corresponding channel light flashes when you adjust the volume until the volume is up to the maximum to stop flashing.
Q9: How many output voltages for maximum volume?
A9: XLR 4.0Vrms/RCA 2.0Vrms.
Q10: Where can I download the latest firmware and drivers?
A10: Please download.
Q11: How can I upgrade the firmware of my LA-QXD1 DAC?
A11: Please refer to the LA-QXD1 Upgrade Guide for details.
