Features:
100W+100W dual-BTL class-D audio amplifier with single power supply
Amplifier chip: TDA7498
Upgrade design: Golden L/R audio input connectors & volume adjustment screw; Free welding power supply connector
Wide range single power supply: 14-32VDC(recommended 19-26V laptop power adapter or 24V power supply, current≥5A, power≥100W; don’t use transformer)
Output power: 100W+100W (Vcc = 36 V, RL = 6Ω, THD: 10%)
Speaker impedance: 4-8 ohm (8 ohm best, 4 ohm or 6 ohm also works)
Four fixed gain settings available: 21.6 dB, 27.6 dB, 31.1 dB and 33.1 dB
Adopts differential input to minimize common-mode noise
Protection: short-circuit protection, over temperature protection
With cut-off and mute features
High efficiency: 85%
Note: Packaging with exposed pad up (EPU), more convenient to mount a separate heatsink

Mode:
Three kinds of modes avaliable: standby/ mute/ normal working mode
Standby mode- all circuits closed, at a low power state;
Mute mode- all input signals connects ground, the duty cycle of forward/backward PWM output signal is 50%;
Normal working mode- the amplifier module works normally.

Package Includes:
1 x TDA7498 2x100W Audio Amplifier Board

Amazon Customer says:

Great little amp with lots of power This amplifier utilizes two 3116 ICs for more power instead of just one like some I’ve seen on Amazon. I have no way to measure the power output but it can go so loud I can hardly believe it. I don’t notice any distortion either. Currently I’m powering it with 16 Eneloop rechargeable AA batteries. At moderate volume levels the heatsink barely gets warm.One thing that led me to purchase this amp instead of one of the similar alternatives was the Sanyo electrolytic capacitors that…

Michael says:

Mine had a faulty capacitor. Some volume tracking issues (my left channel is slightly louder than the right). Sound quality is great but there is noticeable static at higher volumes, so if you like music that has very dynamic volume levels this is definitely not for you. I am using this to power a pair of Micca MB42x’s and it makes for an excellent desktop setup. If you are using a desktop computer with enough headroom in the power supply, you can power it straight off the 12 volt!Update: 1 month of use and one…
