10.1 Heat sink installation
When assembly, we must pay attention to the installation of radiator. The metal shell of radiator
must not be in contact with the surrounding components to avoid short circuit.

10.2 Audio input mode switch
without mounting any audio or external devices; if the external playback device is plugged in
AUX or U disk, the power default is AUX or U disk playback mode; follow the backplug device
priority principle during playback, e. g
inserting AUX, during Bluetooth playback switches to AUX playback immediately; if U disk is
nserted, switch to U disk playback immediately
Switching audio mode is also available with APP selection switch, very convenient.
Try to choose AUX lines with shielding to reduce noise.
U disk playback to use MP3 format as possible, WAV format sampling rate must be within
44100Hz, too high sampling rate may lead to not playback.
When using the USB sound card function, you can connect the computer with the USB data
cable without installing any drive. Most computer systems will switch the USB sound card by
default. If you cannot switch automatically, you can manually choose to switch.
10.3 Power supply selection
The power supply range of 5-26VDC, is compatible with standard 5.5-2.1/2.5 power adapter
plug, recommended 12V/24V standard power adapter with current output above 2A.
Select the power size is related to the horn power used, such as using 8 ohms 50W horn, using
24V power supply, current at least 4A, too low current may appear sound lag phenomenon,
reduce the output power can solve this problem; using 4 ohms horn, the power supply control
within 20V, too high voltage may make the power discharge fever serious.
Below 9V power supply works, but the output power is extremely small, so the supply voltage is
above 9V, and 12V/24V standard power supply is recommended.
The supply voltage must not be higher than 26V, and higher than 26V, circuit board is burned.
If the volume is increased during the playback process, the power amplifier board is restarted,
which is caused by insufficient power supply, and you can replace the power supply with a larger
output current.
10.4 Hororn selection
This product power amplifier can continuously output 50W*2 of power, 10W~100W horn can be
promoted, using 8 ohms or 4 ohm horn is recommended. If the power is within 50W,
appropriately reduce the supply voltage (such as 12V power) or reduce the playback volume; the
greater the horn supply voltage greater than 50W, the better (within 26V).
If the music horn appears "hiccup" phenomenon, the first consider the lack of power supply, a
larger power supply to use power supply; the second consider the power spare heat protection,
strengthen heat dissipation or reduce the playback volume.
If multiple horns are used in parallel, be sure that the total impedance after the horn in parallel is
controlled above 4 ohms, too small impedance, the power amplifier is easy to enter the
overcurrent protection state.

10.5 Signal problem
This product uses a PCB antenna with the visible distance of 15 m without shielding. If you
do not find Bluetooth, or connect to Bluetooth, it is a signal problem.
1）Stay away from the router when used.
2）Avoid use on metal tops, which will affect the PCB antenna signal.
3) Modify the speaker, if it is a metal shell, be sure to lead the antenna from the shell, the
metal will shield the signal.
11.How to connect your mobile phone to
Bluetooth
Make sure that Bluetooth enters Bluetooth connection mode- - -blue LED flash, AUX do not
insert, can not enter Bluetooth connection state after insertion
Search for Bluetooth on the mobile phone, found "complete the connection after XINYI", click,
accompanied with the prompt sound. After the successful connection, the LED enters the long
beam state, open the mobile phone music software to play music, blue LED flash, enter the
playing state;
When the phone searches for Bluetooth, come out. "Sinilink-APP", don't connect this Bluetooth

here, this is connected inside the APP. If connected, please cancel the pairing and search again,
otherwise it will cause you unable to connect inside the phone APP.
12.How to download a mobile APP
Scan the code to download APP, foreign customers please download in Google Market,hunt for
‘sinilink’download.

15.How to distribute the distribution
network
In the operation interface, press SET button for more than 5 seconds to enter Touch pairing state,
and press SET button again for 5 seconds to enter AP pairing state.
Touch mode: Blue light interval 1 second flash 4 under AP mode: Blue lamp continues to flash
quickly
Enter the Touch pairing mode by default. If the pairing fails, please select the AP mode, connect
the WIFI network with a "Sinilink Product", password of "12345678" and operate according to
the APP prompt.
