Description
High fidelity HIFI sound: Use imported TPA3116D2 chips with excellent power amplifier effect. The distortion is less than 0.1% even at high output power. Modulation frequency up to 1.2 MHz, built-in LC filter capacitor to make the vocals clearer. Parameters: Input voltage: DC 12V-24V; Maximum output power: 50W x 2 (R&L) + 100W (subwoofer)); Input method: Bluetooth & AUX; Channel: 2.1CH stereo output; Output impedance: 4-8Ω; Bluetooth version: BT 5.0 AUX and Bluetooth input: Bluetooth 5.0 version, transmission distance is further away. The transmission distance can reach 49 feet in an open environment. If your playback device does not have Bluetooth, you can also input audio signals via the 3.5mm headphone jack. Protection function: this amplifier board has overheating protection, reverse protection, circuit protection, overvoltage and undervoltage protection 【After-sales service】 Paying attention to the customer experience and satisfying customers is our service principle. If you have any questions about the product or have quality problems, please contact us at any time. › See more product details; Product description Product name: 2.1 channel TPA3116D2 Bluetooth amplifier. AMP chip: 2 x TPA3116D2. Maximum output power: 2 x 50 W + 100 W. Power supply: DC12 ~ 24V. Channels: 2.1. Output impedance: 4 ~ 8 ohms. Working type: Class D Audio input: AUX / Bluetooth 5.0. Package includes: 1 x ZK-TB21 power amplifier board. 1 x protective case. 1 x DC plug. 1 x screwdriver. 5 x buttons. Note: Only if the audio input is sufficient and the voltage/current input of the power supply is sufficient, enough power can be output. The higher the supply voltage, the greater the output power. The smaller the impedance of the speaker, the greater the output power. It is recommended to use a 4Ω speaker. Finally, make sure the power of the adapted power supply is greater than the actual working power of the AMP to ensure the maximum output power. Warm reminder: The power switch on the board is a standby switch. After power off, the device is in a standby state with low power consumption. To completely turn off the power or disconnect from the mains for a long time, you can unplug the DC plug on the device. By properly increasing the voltage or reducing the speaker impedance, the output power can be effectively increased.; Product description Product name: 2.1 channel TPA3116D2 Bluetooth amplifier.
