In audio work, a tracker and oscillator are essential. The first one you connect to the input of the audio ci and Czech signal, the second you connect it to the amplifier input and check if it has output. - This allows you to locate if you have a problem of signal input or do not have amplification. With regard to the Czech voltages the one of mute. I send you a diagram of the one we use. Regards .
