Audio Preamplifiers – II

Below (Figure 1), a diagram of a hypothetical microphone pre-amplification circuit with the presence of additional controls as equalizer for high frequencies and equalizer for low frequency. Fig. 1 At the hardware level, basic, there are two types of analog microphone pre-amplifiers: Inboard Outbard Inboard Fig. 2 In figure 2 illustrates a generic scheme of … Continue reading Audio Preamplifiers – II

Audio Preamplifiers – I

The audio preamplifier as deduced from the word itself is a component used to amplify an audio signal before the final amplification. Pre-amplification and final amplification are two separate things not to be confused. The final amplification is the amplification of the signal with line level (0.770 v - 1.223 v) up to power values … Continue reading Audio Preamplifiers – I
