TDA7498E 160Wx2 Power Digital Audio Board Dual Channel Stereo Sound Speaker Support BTL Mode Module

Related Productions: Notes:The fan only begin to work if temperature of reach the point. Sound is very good and it can drive 4/6/8 ohm speakers. It has and high power output 2 x 160W. It supports BTL mode and when heat sink temperature rises to a certain extent, the cooling fan will work. Feature 1, High output power digital . 2, DC 15-36V power supply, with reverse polarity protection. 3, When heat sink temperature rises to a certain extent, the cooling fan will work. 4, Support BTL mode ( J1, J2, J3, J4 on the back of board should be shorted), 36V 3ohm for single channel with 220W output. 5, Two-channel stereo, sound is very good. Specification Chip: TPA7498E Channel: Channels*2 input voltage:DC 15-36V(Recommend 32V,8A) output power:160w*2 Speaker Resistance:4/6/8 Ohm Effciency:85% PCB size:108*78mm/4.25x 3.1" Packaging Including: 1xPC TDA7498E Board Product Questions 1. board has current sound and noise during use Most of our board use DC power supply. The board itself does not produce current sound and noise. The main causes of current acoustic noise are: A, The power supply filter used is not good; the current sound is caused by wrong input by the power or audio input. B, The input signal is poor; the output of the device connected to the input is improper, and the noise is caused by the abnormal input of the audio source. C, The input cable is of poor ; the line is in poor connect; the wiring is damaged; the wiring is suspended D, The input connection has other playback devices, and some devices share the power supply to cause noise. 2. No sound output, no sound in 1 channel? A, The speaker is broken, or the speaker cable is not conne
