Almost all commercially available microphone amplifiers draw their power from a 48V phantom power supply. If this is unavailable or unsuitable, the solution is to build a self-powered amplifier.
I'm running Ubuntu Studio (just upgraded to 14.10) with a Presonus AudioBox 2x2 USB audio interface. For Christmas I got myself a new MXL 990s condenser mic (60% off, sweet!), but when I plug it in ...
Most PC “mic” inputs are pretty average for noise and distortion, and they’re usually mono. Plus, they can’t properly take balanced, pro microphones that often need 48-V phantom power. This ...
The circuit in Figure 1 is suited for inductive sources such as a dynamic microphone, transformer or inductance sensor/pick up. Figure 1 A simple amplifier circuit suited for inductive sources such as ...
