Here is a description of one of many possible options for neslozh leg BASS amplifier designed for enhanced analog BASS signal from the output of the digital source such as a DVD player or mp player, satellite receiver and etc.
Усилитель двухканальный, развивает мощность 2x12W, при мощности до 2х6W коэффициент нелинейных искажений не более 0,3%. А при максимальной, – до 10%. Есть регулятор тембра, регулятор громкости и стереобаланса.
The amplifier is made on the basis of the block to power low-voltage halogen lamps, so-called "electron leg transformer and TDA1518BQ chips, plus the passive scheme regulator timbre, volume and balance.
The actual amplifier placed on micro scheme A1 TDA1518BQ. Instead, you can use another chip-tech counterparts destination.
TDA1518BQ chip is enabled on the model scheme work as two normal multi-channel UNTCH (no bridge). To transfer chips in this mode serves as a bridge between 2 and 4 Dami conclusions.
Прежде чем попасть на входы усилителя аудиосигнал поступает на нормирующие регуляторы R1, R8 и схему пассивных регуляторов громкости, тембра и баланса на переменных резисторах R11, R12 и R13. Резисторы R11 и R12 – сдвоенные, кроме того, R12 – с отводами. Резистор R13 – одиночный.
Резистор R11 служит для регулировки тембра. R12 – для регулировки громкости. Одиночный резистор R13 служит для регулировки стереобаланса.
For power amplifier uses an electronic transformer» power fully 75W designed to supply halogen lights re present voltage of 12V. It stresses ing with the release of "electronic inch transform Tora" is served on the rectifier on a bridge Here. Capacitor C9 smooths out the bullets, compensation.
If you will use the "otkljuchajushhijsja" electronic transformer in low load to ULF nor worked in parallel as you will need to connect the bulb C9 12V dogruzit power source.
