Line To Mic Level Converter

0:00 / 9:09 •. Live. •. In this video, the presenter will show you how he constructed a Line level to Microphone adapter to record audio from your phone or stereo to your computer or camera, when the recording device only has a stereo microphone jack.

Usually you will be using -36dBu with line level output from the D/A converter . This level could be as high as +21dBu so it will need to be attenuated enough for a mic -pre to be useful. The output impedance of this setting is consistently held at 150Ω. The -24dBu attenuation setting is mostly for tape machine, ADAT, DAT, or older digital medium.

A line level signal is approximately one volt, or about 1,000 times greater than a mic level signal. One volt is also expressed as 0 dBV – so a line level signal is about 40 to 60 dB higher than mic level . Most audio mixers have a line level output that is suitable for connection to a power amplifier, signal processor, or audio recorder.

Convert line level signal to mic input signal level . Level out = V1 * (R2 +R3)/(R1 + R2 + R3). The actual R values are not so important. ...

Mixers will boost a mic signal to line level , and you can also use a mic preamp or a mic to line amp to manage this as well. Mic inputs will nearly always be XLR and Line in will always be a 1/4″ jack. Aux Level . Aux level is pretty close to line - level , (0.3 volt), but the main difference is that Aux level ins/outs are nearly always unbalances.

Check that the PC is configured to use the correct recording device under Control Panel > Sound > Recording. Select the proper recording device, right-click on it, and select "Set Default Device" or "Select Default Communication Device". Ensure the PC supports the combined audio jack. If not, please use the included audio/ mic splitter cable.

Good little box for dropping line signal levels down to Microphone input level . Good little attenuator box to convert line signal to mic input levels. For instance, when copying analogue audio signals from a line level device such as a disc player or mp3 player and your receiving device only has a microphone socket.

Mic - level signals are weak and line - level signals are . Mic inputs use a female XLR connector. Line inputs require RCA, ¼” phone jack, or 3.5 mm phone jack. A mic - level signal must be raised to a line - level signal through a preamp or mixer. Connecting a line level source to a mic -in will lead to distortion.
