Product Description & Reviews
Package Included: 1x INSMA TDA7492P Audio Receiver Amplifier Board Parameters Amplifier IC: TDA7492P-Stmicroelcctronics Sound Source: DCM8633 Bluetooth 4.0 module Product name: Wireless Bluetooth 4.0 Audio Receiver Digital Amplifier Board. Power Supply: 12V 3A (Recommend), steady 9-20V. Output Mode: Stereo Efficiency: 90% Output Power: 25W+25W; THD=10%; Vcc=18V; RL=6Ohm Adaptive Speaker: 20W/4Ohm; 20W/6Ohm; 20W/8Ohm Control Mode: Bluetooth, Button Board Size: 82mmx51mmx20mm (L*W*H) Weight: 90g Color: Red How to connect Connect to power supply, press the power switch, wait 3 seconds, until the blue and red LED flashing alternately, then use phone or other Bluetooth transceiver device to find the Bluetooth power amplifier, mobile phone display "INSMA Audio", click to connect. Support device memory and automatic connection. Note 2. Volume as far as possible not to open to the maximum to protect the speakers. 3. It is recommended to use only Bluetooth as the audio input. 4. Gain switch: the default setting is 21.6 dB. 5. LED alternating flashing: wait matching. 6. One LED flashing: connect successfully. 7. The second function of the PLAY button: long press the button can be directly into the waiting matching mode. 8. To get high quality effect, please make sure amplifier board and speaker matching. Under normal circumstances, we choose "power amplifier board power: speaker power =2:1", which means 25W amplifier board is suitable for driving 15W-25W speakers. If the matching parameters are incorrect, then the effect will be all sorts of strange things.
Features & Highlights
- Fits the 25 W board best fits 8 Ohm and 15W-25W loudspeaker
- Output Impedance: 4/6/8 Ohm, impedance can drive speakers
- Chip: TDA7492P, powerful and high efficiency
- Power supply: 2.1 interface 8-20V steady DC power supply, best with 12V/3A. Overload may burn the board. If you want to connect to higher voltage, please control electricity properly
- DIP switches can be adjusted directly after the amp gain more respect and better promote greater damping horn
