• 12V Mini Multi Zone Bluetooth Amplifier

  This advanced device has multiple independent amplification zones. Different music can be streamed from a smart device and played through different amplifiers in the same area. Activities can be continued without interfering with others. The amplifier allows simultaneous multi-zone audio. Users who want to set up whole home or multi-room audio systems.

Functions and Features

The 12 V mini Bluetooth amp has various features that improve user experience, connectivity, and sound quality. The following table summarizes the features and their functions.

• Speaker Protection Buzzer

  The speaker protection buzzer safeguards the speakers when there is an unexpected drop in the amplifier's power supply. If the amplifier supply voltage changes suddenly, the buzzer makes a noise instead of the speakers. The sound alerts the user to a change in the amplifier's voltage level.

• Input Sensitivity

  Input sensitivity is the lowest signal level needed at the amplifier's input to reach the maximum output level. A low input sensitivity means the user will have to turn up the source's volume very high, while a high sensitivity allows the user to keep the source's volume at a normal level. So, if the 12 V mini amplifier has very low output power, it needs high input sensitivity to produce loud sound. High sensitivity means the amplifier can produce high volume even with a small input signal.

• Device Pairing

  Device pairing refers to the process of connecting two devices via Bluetooth. It is the first stage of a Bluetooth connection. After pairing, the devices connect automatically every time they come within range of each other. To pair, the devices must be in pairing mode, and the user may have to enter a passcode or confirm the connection.

• Device Connection

  Device connection occurs after successful pairing. The two devices transfer data between them. The user can now use the connected device to send audio to the amplifier and listen to the amplified audio output. The range of a Bluetooth connection is 10 meters (33 feet) for Bluetooth 5.0 and 30 meters for Bluetooth 5.2.

• Working with Phones

  Studies show that over 90% of Bluetooth devices work and connect with phones. The mini Bluetooth amp also connects and works with phones. Users can stream audio from their phones to the amplifier and enjoy the amplified sound. The phone can be seen as the source device, and the amplifier is the destination device. Common usages are calls, music, and videos.

• Working with Other Devices

  Besides working with phones, the mini amplifier can connect to other devices like tablets, PCs, laptops, and gaming consoles. Users can stream music from their tablets and watch videos through a connected PC. Also, gamers can amplify sounds from their gaming consoles.

• Audio Output Channels

  The audio output channels show where the amplified audio signal from the mini amplifier can go. It can be either to speakers or to the subwoofer. Some amplifiers have separate outputs for subwoofers and speakers. This allows users to give their audio systems more bass by adding a subwoofer. If the amplifier has only one output for speakers and subwoofers, users can use a cable splitter to connect a subwoofer and speakers.
