amplifier circuit


Posted on Feb 5, 2014

The XLR connector allows us to connect the microphone`s output to our preamplifier circuit. This preamplifier was designed and built by our Electrical Engineers using discrete components. The preamplifier`s signal is then fed to the Maxim Class-D amplifier. The output is low-pass filtered and delivered to the speaker. Because we are not transmitti
