The PC’s own USB port for power supply is not enough to support the normal operation of LA-QXD1 (DC:5V@1A).
XLR output 200 Ω and RCA output 100 Ω.
LA-QXD1 does not have memory function, it will return to the default state after powering on/off.
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.
(Note: Switch to the filter mode you want to play, and don’t need to press a different button to confirm).
The default volume is -60dB, the adjusted volume stride is 2dB/Step, and the maximum volume is 0dB.
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.
XLR 4.0Vrms/RCA 2.0Vrms.
It is not recommended to use as a headphone amplifier.
To support PCM768KHz and DSD512.
Windows 8.1 and earlier versions require a driver. Windows10、MAC OS、OSX 、Linux does not need a driver.
Note：All Windows platforms that need to support PCM768k and DSD512 must have our official custom drivers installed.
The default filter mode of the LA-QXD1 is the Apodizing Linear Fast Roll-Off Filter (APOD).
No, Powering off the LA-QXD1 resets the filter mode, but you can easily set your preferred filter mode.
No, but you can easily set your preferred filter mode.
There are seven filter modes available in the LA-QXD1 DAC (APOD-BRIC-FAM-FAL-HYER-SLM-SLL). Press and hold the mute button for two seconds to change the filter mode. Each time you press hold the mute button for two seconds, you’ll cycle through the available filter modes.
The LED lights (TOS/COAX/USB) will combine to indicate the selected filter mode, As shown in the table below.
Yes. Please refer to the filter table below. The LED lights (TOS/COAX/USB) combine to indicate the selected filter mode.
See LA-QXD1 DAC FILTER MODE TRUTH TABLE
The LA-QXD1‘s volume control goes from -60dB to 0dB. Each volume step adjusts the volume by 2dB increments. Therefore the LA-QXD1 has 30 volume steps.
XLR: 4.0 Vrms, RCA: 2.0Vrms.
Yes, The LA-QXD1 DAC is compatible with 32 kHz sample rate via SPDIF.
Older versions of Windows up to and including Windows 8.1 require a driver installation. Windows 10, Mac OS, and Linux are plug and play, so no drivers are needed.
Note: If you use Windows 10 and want to play PCM768k and DSD512 files, you‘ll need to install our official custom drivers. Please refer to our official website for more details.
The chip models are: ES9311Q、TPS65131、MP20051DN、ADP151AUJZ-3.3-R7、L7812CD2T-TR、L7912CD2T-Tr and so on.
The output of the LA-QXD1 DAC is variable.
You can check this teardown by Audio-monkeys for pictures of the internals: https://audio-monkeys.com/dac/soncoz-la-qxd1-en/
No. Xmos has no official upgrade tool available for Mac OS or Linux.
Yes, Both DSD rates are supported.
Using any SONCOZ DAC as a headphone amplifier is NOT recommended.
The latest version is „LA-QXD1 Minimum Volume DFU_V401“.
You can download the latest firmware here: http://www.soncoz.com/uploads/1/2/7/2/127246176/la-qxd1_dfu_0710.zip
Many of our users enjoy using their SONCOZ DACs with ROON with great compatibility.d
Our upcoming DACs will support MQA.

The volume adjustement buttons work with all three input sources.
The drivers add support for high sample rates: PCM768K and DSD512.
The WiFi function of SGD1 is only used to upgrade the system software, without any other functions, and there is no data collection behavior.
XLR and RCA are output at the same time, and the two interfaces can be connected to the power amplifier equipment (headphone amplifier/power amplifier) of the corresponding interface at the same time.
The SGD1 is a high-performance DAC that can also meet the requirements of pre-amp applications.
DAC internal modulators, filters, and volume controls cannot be bypassed,which is determined by the DAC chip.
SGD1 can be used as a pure decoding device, adjusting the volume to the maximum.
Volume adjustment and mute functions are only valid for analog output and not for digital output.
When the DSD source is playing, the DSD audio stream directly into the DAC chip with no transcoding in the middle.
The customized USB driver supports PCM768KHz/DSD512 (Native). If you use the built-in driver of the system, there may be problems with high-spec audio sources that cannot be played.
Information about the currently playing audio source is displayed on the custom-driven control panel installed on the PC side.
The volume and filter mode of each input source of SGD1 can store memories separately and the next power-on returns to the last setting.
Press and hold the button for more than 6 seconds, all indicators are on and reset to the default power-on state.
The default volume is -64dB, the encoder adjusts the volume stride is 0.5dB/Step, the maximum volume is 0dB. The volume of SGD1 can be realized by turning the knob quickly or long pressing remote control +/-.
There are two ways to upgrade: mobile phone hotspot and mobile phone APP (Esptouch). Please refer to the SGD1 Upgrade Guide for details.
SGD1 will configure the WiFi network before connecting each time it powered on. If the network exists, it automatically detects if there is new software and update, and then turn off the WiFi function, if the network does not exist, the WiFi will be turned off one minute after powering on.
Bluetooth for SGD1 periodically scans the connected devices to ensure that they are automatically connected.
Support APTX / APTX LL / SBC / AAC and other format.
Each SGD1 uses 2 ES9038Q2M as audio decoding chips.
Compatible with multiple operating systems Windows/iOS/Android/Linux/Volumio.
Yes, all our products are hump-free.
XMOS has removed and no useless.Thesycon support DSD512 and PCM768KHz
The user cannot see the version of the software. Under normal upgrade operation, if no new upgrade occurs, and judge as the latest version of the software.
XLR output 200 Ω and RCA output 100 Ω.
XLR 4.0Vrms and RCA 2.0Vrms.
The SGD1‘s volume control goes from -64dB to 0dB. Each volume step adjusts the volume by 0.5dB increments. Therefore the SGD1 has 128 volume steps.
Currently, the user can‘t check the firmware version. When using the SGD1 and attempting to upgrade, if no upgrade happens, then the SGD1 is using the latest firmware version.
