TDA7498E Amplifier Digital Power Amplifier Board Power Amp 2x160W Stereo Support For BTL 220W Mono
Features:
- Power Class D digital power amplifier
- Amplifier Chip: original TDA7498E (TDA7498E is a 2x160W chip)
- Output Power: 2x160W (Using 4Ω impedance speaker unit, input voltage 36V DC, output power 160W+160W)
- Working Voltage: 15~36VDC, with input polarity reverse connection protection (the speaker's real power is large enough. The recommended voltage is 32V, 8A or above DC power supply. Too small power supply will cause distortion and sound interruption, and no shock effect)
- Loudspeaker Impedance: 4Ω, 6Ω, 8Ω
- Heat Dissipation Method: Temperature controlled forced air cooling (when the temperature of the heat sink reaches a certain level, the fan operates to remove heat)
- Work Efficiency: 85%
- Support for BTL Mode (J1, J2, J3, J4 on the back of the amplifier board is short-circuited): 36V power supply 3Ω mono 220W output (TDA7498, TDA7498L chip does not support this function)
Package Included:
- 1 x Power Amp Board
