Features:

- Multiple Audio Input Modes: This Mini amplifier receiver built-in Bluetooths 5.0 and 3.5mm AUX Input. Bluetooths 5.0 mode, faster transmission speed, lossless decoding, lower distortion rate, connection distance to audio equipment is 10m/33ft. Note: When using AUX mode, please confirm that the Bluetooths connection of this module has been disconnected. - Multiple Protection Function: This Bluetooths amp module is designed with multiple protection mechanisms, include over-voltage protection, under-voltage protection, over-heat protection, short-circuit protection, inverse connection protection, with case to protective it. Equipped with 4 shielded power inductors to suppress electromagnetic interference (EMI) and enhance system stability. Besides, there is a 35 * 25 * 10 mm cooling fin above audio chips, used to reduce the dissipate heat for amplifier chips, reduce temperature rise and its impact on sound quality, and ensure long-term stable working of the components.- 2.0 channel Subwoofer Audio Amplifier Board: This ZK-1002T power amplifier is 2.0 channel, allows you to connect 2 passive speakers, comes with Treble and buttons, which is very friendly for audiophile, you can adjust the Treble and buttons, make the more shocking and the treble clearer, make the sound more layered. - High Definition HIFI Stereo Sound Effect: The ZK-1002T power amplifier board built in two TPA3116D2 power amplifier chips, TPA3116D2 is a high performance class D power amplifier chip, can make the device maintain ultra low distortion in the whole audio frequency band and show high resolution audio at the same time. The wiring around the chip is an window tin spraying design to increase the output power. 2 x Low noise preamplifier 5532 group can improve the sound quality and volume, increase the gain. - 100W + 100W High Power Output: This 1002T audio amplifier has a maximum output power of 100W for the left and right channels respectively. It can drive two high-power speakers (20 - 200W, 4-8 ohms), and the adapted power supply is DC 12 - 24V / 5A or above. The higher the power supply voltage/current, the higher the output power, and the lower the speaker resistance, the higher the output power. The power adapter power must be higher than the actual working power of the amplifier. At higher volume levels, audio output exhibits signal clipping and muddiness. - Mitigation: Reduce master gain or use a power adapter with higher voltage compliance.

Audio stuttering occurs at elevated SPLs. Root causes: - (a) Insufficient PSU wattage triggering intermittent shutdown. - (b) Thermal throttling from sustained high-power output. - Resolution: Upgrade to higher wattage PSU or implement active cooling.

End-to-end audio fidelity is governed by systemic synergy, not solely the amplifier module. Critical components include: - Signal integrity: Interconnect cabling (impedance stability) - Power delivery: PSU noise floor & ripple suppression - Signal processing: Tone control circuit linearity - Transduction: Loudspeaker THD & frequency response - Environmental: Acoustic loading & ambient noise - Optimal performance requires matching: Source, PSU, Amplifier, Transducer. Place of Application: - Car Audio System / DIY Speakers / Home Theater Note: - The casing of the amplifier board needs to be assembled by oneself. - The input power must be greater than the actual working power of the amplifier. - Only when the audio signal input is strong enough and the power supply voltage and current are large enough, can sufficient output power be guaranteed.

Package Including: 1 x Power Amplifier Board 1 x Set Protective Shell 1 x DC Plug 3 x Knob 1 x Screwdriver
