Warm Reminder:
* When connecting the DAC to other devices such as headphone amplifiers or power amplifiers, set the DAC volume to 100 and control the volume via the backend device to achieve maximum dynamic range. (Note: Some devices may produce distortion at maximum volume; please reduce the volume if this occurs.)
* The Italian sound card firmware (for AMANERO) supports DSD512 playback on Windows systems by default. If support for Daphile systems is required, please notify us in advance (Note: The two systems are not fully compatible). USB interface for XMOS 316 supports both systems.
* This unit is a pure DAC without a headphone amplifier.
* The HDMI-compatible port is not a video port; it is only for I2S input from streamers or digital interfaces. Since there is no universal standard for I2S interfaces, it may not be compatible with all I2S signals. Issues such as no sound or noise are not considered quality defects.
* Since most components use imported materials, supply may be intermittent or out of stock due to international factors. We reserve the right to modify materials or design without prior notice.
* Please contact customer service to obtain the USB driver.

Notes:
1. Install the Bluetooth antenna onto the antenna base; there is no need to tighten it excessively. Over-tightening may twist the internal wires of the base, causing a break and preventing Bluetooth detection.
2. If the Bluetooth device fails to pair, power off the DAC for 1 minute, then turn it back on and retry pairing.
3. When playing via Foobar, it will take exclusive control of the device for Amanero, preventing other software from outputting audio. To use other software, stop or close Foobar and set the device for Amanero as the default device. (You can also disable exclusive mode in the device properties for Amanero.)
4. If audio plays in mono only via Bluetooth, LHDC function is likely enabled. Since this Bluetooth module supports LDAC but not LHDC, a conflict occurs. Disable the LHDC function to restore normal stereo playback.
5. The acrylic surface has a protective film; this is not a scratch. Peel it off after confirming receipt of the product.
6. If no audio is output, unplug the power cable for 5 seconds, then reconnect it.
