Description
BTL 320W Mode Amplifier TDA7498E 2*160W High Power Digital Power Amplifier Board HIFI Stereo Power Amplifier Module
Product Paramenters
Power amplifier chip: original TDA7498E (TDA7498L is 2X80W chip TDA7498 is 2X100W chip, TDA7498E is 2X160W chip) Output power: 2X160W (using 4 ohm impedance speaker unit, input voltage 36V DC output power 160W+160W) Working voltage: 15~24VDC DC with input polarity reverse protection (the actual power of the speaker is large enough, the recommended voltage is 24V, 8A or more direct current, the power supply is too small, the distortion will be broken and so on.)
Heat dissipation method: temperature controlled forced air cooling (heat sink temperature is high to a certain extent, fan operation is forced to dissipate heat)
Support BTL mode (J1, J2, J3, J4 short on the back of the power amplifier board) 36V power supply 3 ohm mono 220W output (TDA7498, TDA7498L chip does not support this function)
