WD850B WIFI Audio Box Manual

WD850 2.0 standard version mainly focuses on network streaming media playback + high-end aptxHD wireless bluetooth audio reception + AUX/optical/coaxial + U disk lossless playback, (hereinafter referred to as WD850B), with “the sparrow is small, complete with internal organs” to describe WD850B can be It is more suitable. It is only half a sheet of A4 paper (249*85*35mm), but it can provide a variety of music usage methods to meet the diverse needs of HIFI music playback + audio-visual. The WD850 can be connected to the network through a network cable or Wi-Fi, so it does not matter if there is no network cable near the speaker, allowing users to arrange the location of the speaker more flexibly. In addition, the Wi-Fi function also allows the multi-room playback capability to be utilized more effectively, enabling multiple group playback with streaming media players such as the WR320 under the AYNIO brand.

Short press the play button: playback pauses;

Long press the play button (3 seconds): Bluetooth enters forced pairing and connects to a new device;

When Bluetooth cannot be paired: Delete all connected Bluetooth device records from the phone or tablet. Reconnect the device after restarting the phone or tablet to restore the device’s Bluetooth driver. (or refer to the FAQ below)

5. It is strongly recommended to connect the speakers through Bluetooth mode debugging to ensure that the power amplifier or speaker is correctly connected to the WD850B and makes sound. If there is any abnormality, connect the AUX output of WD850B to the 3.5mm headphone, check that the output of WD850B is normal, and then connect the speaker to switch to other modes.

6. Network streaming media playback mode,

Wired networking: WD850B can access the Internet through RJ45 wired or WIFI wireless. When choosing wired networking, just connect the RJ45 network cable connected to the router to the device, and the two indicators on the RJ45 network port of the device will light up. That is, automatically obtain the network IP address to connect to the Internet. The mobile phone only needs to download the APP or directly use the software that supports streaming media playback, such as QQ music, to ensure that the mobile phone is connected to the same router WIFI signal, and the device can push the streaming media playback within the same local area network as the device. It is recommended to use the QPLYA function of QQ Music, which supports list push.

Wireless networking:

1. When the router supports and enables the WPS one-key networking function, it can be automatically paired by pressing the WPS button of the router and the WPS button of the WD850B.

2. You can also choose to download WIIM (Legacy Play) software for wireless networking.

Copy the URL to open and download http://www.aoyint.com/software/MUZOV3.apk or scan the QR code below

3. Whether the corresponding indicator light corresponds to the correct mode

4. Confirm that the power amplifier is turned on and correctly connected to the unit

5. Confirm the volume settings of the player and power amplifier and whether it has been muted

6. Whether the sound of the signal source device is set to the corresponding optical fiber or coaxial output signal

7. Confirm whether the optical fiber coaxial input audio format is the PCM supported by the product

3 There is noise/abnormal sound

1. Confirm whether the input audio signal format is the format supported by the product

2. Check whether the analog output of the decoder and the output of each channel of the power amplifier are connected correctly

3. Confirm whether the connecting line is in good condition and connected reliably

5 Unable to operate

1. The buttons cannot be operated: please power on again and try again

2. The remote control cannot be operated: within 10M of barrier-free operation, check whether the remote control battery is installed or reversed, and whether the battery power is exhausted (please replace the battery)

3. Press the button on the remote control, the remote control head flashes, indicating that the remote control is working, if it does not flash, the remote control is not working

6 Bluetooth wireless pairing

• Make sure the product is in pairing mode

• Make sure this product and the paired device are within range (the mobile phone is close to the device first)

• Delete all connected Bluetooth device records from your phone or tablet. After restarting the phone or tablet to restore the device’s Bluetooth driver, reconnect the device.

• When the distance is too short or the disconnection is unsuccessful, please check whether there is too much interference from 2.4G wireless devices around the environment (such as WiFi signal, wireless mouse, other Bluetooth devices, etc.).

• Please do not place the device on metal objects and do not block them. When the signal is interfered or blocked, it may also cause the sound to be intermittent/stuttered.

Note: U disk can not be recognized? U disk partition table can be changed to mbr

The U disk was originally in MBR format, but now it is used for one-key boot installation system. Some U disks are changed to default GPT (partition table format is GUI format). When the decoder device does not recognize the GUI format U disk, we need to convert the format. For MBR format, the conversion method is as follows (as shown in the figure)

1. DiskGenius is a super hard disk partition tool that can switch the U disk back to the MBR format. Download to local installation: (Please refer to the original official website instructions carefully to avoid damage to the U disk). DiskGenius official website: https://www.diskgenius.cn/download.php

2. After connecting the U disk to the computer for identification, copy the files in the U disk to the local hard disk of the computer for backup.

3. Refer to the picture to format the U disk as MBR format, select a partition, FTA32 format.

4. After format conversion. Copy the audio files to the U disk.
