Circuit Schematic Stereo Preamplifier using LA3161 IC

Audio. - This is electronic circuit schematic of Stereo Preamplifier using LA3161 IC like in Figure 1 below. In this circuit schematic the basic component used is LA3161 IC. 

In here we will give you global description about circuit schematic of Stereo Preamplifier using LA3161 IC and then we will give you link to continue your reading from original source as external website.

Circuit Schematic

Component Part

  • LA3161 IC
  • Resistors
  • Capacitors

Circuit schematic like in Figure 1 above is Circuit Schematic Stereo Preamplifier using LA3161 IC. Circuitstoday site describe that in the circuit both of the built in amplifier section are used. Capacitors C8 and C9 are input coupling capacitors. Capacitors C3 & C6 are noise filter capacitors. The lower cut-off frequency depends on the value of C3 and C6 network comprising of components R1, R2 & C1 defines the frequency characteristics of left channel and the network consisting of R3, R4 &C2 defines the frequency characteristics of the right channel. C4 and C5 are output coupling capacitors. C7 is the power supply filter capacitor and it must be connected as close as possible to the power input pin (pin 4) of the IC. This IC doesn’t have short circuit protection, and short between pins may cause damage. C10 and C11 are meant for preventing radio interference, interference from engines etc.
