4.1 Ukuxhuma Amandla
Connect the included 12V DC power supply to the DC12V input on the amplifier. Plug the power supply into a standard wall outlet.
For automotive or motorcycle applications, you can hardwire the amplifier to a 12V battery system. Use the included PSU's wire and connector. Strip the wire as shown in the diagram below. The white wire is POSITIVE (+), and the bare wire is GROUND (-). It is recommended to install a 2 Amp fuse inline (not included) for protection.

Ukuxhumana kwesipikha
Connect your passive speakers to the SPEAKER OUT terminals on the rear panel. Ensure correct polarity (positive to positive, negative to negative) for each channel (Left and Right). Use a small screwdriver to press the terminal tabs, insert the speaker wire, and then release the tab to secure the wire.

Qaphela: Avoid using excessively large speaker wire that may cause shorts. Soldering the ends of the speaker wires can prevent stray strands and improve connection reliability.
4.3 Ukuxhumeka Kokufaka Umsindo
- Okokufaka kwe-AUX: Connect external audio devices (e.g., smartphone, MP3 player) using the included 3.5mm audio cable to the AUX IN jack.
- USB/TF Card: Faka idrayivu ye-USB flash noma ikhadi le-TF (Micro SD) eliqukethe umsindo we-MP3 files into the respective ports. The amplifier will automatically detect and play compatible files.
- I-FM Antenna: Connect the FM antenna wire to the FM ANTENNA input for radio reception.
4.4 Remote Control Connection
- Wired Handlebar Controller: Plug the handlebar controller cable into the REMOTE LINE IN jack on the ampiphaneli yangemuva ye-lifier.
- Wireless IR Remote: Ensure the IR receiver on the front panel (labeled 'IR') has a clear line of sight to the remote control.
5. Ukusebenza
5.1 Vula/Vala amandla
The Kinter A7BT amplifier does not have a dedicated power on/off button. It powers on automatically when connected to a 12V DC power source and powers off when the power source is disconnected.
5.2 Ukukhetha Imodi
Cindezela bese ubamba i M/P/P button on the front panel or the 'MODE' button on the IR remote to cycle through the available input modes: Bluetooth, AUX, USB, TF, and FM radio.
5.3 Ukulawula ivolumu
Adjust the volume using the:
- Iphaneli yangaphambili: Cindezela isikhathi eside i NEXT/P button for Volume Up, and long press the PREV/V button for Volume Down.
- Handlebar Controller: Sebenzisa i- OKULANDELAYO/V+ button for Volume Up, and PREV/V- button for Volume Down.
- Isilawuli kude se-IR: Use the dedicated Volume Up and Volume Down buttons.
5.4 Ukulawula ukudlala
Control audio playback using the:
- Iphaneli yangaphambili: Cindezela isikhashana NEXT/P for next track, short press PREV/V for previous track, short press M/P/P okokudlala/ukumisa kancane.
- Handlebar Controller: Sebenzisa OKULANDELAYO/V+ ngethrekhi elandelayo, PREV/V- for previous track, and I-P/P okokudlala/ukumisa kancane.
- Isilawuli kude se-IR: Use the dedicated track skip and play/pause buttons.
5.5 Ukumatanisa kwe-Bluetooth
When the A7BT amplifier is powered on, it is ready for Bluetooth pairing. Follow these steps:
