ARRL Handbook Audio Intelligibility Enhancer
Assistance is sought for building the N4GG audio intelligibility enhancer project as detailed in the ARRL Handbook. A circuit board has been ordered from Far Circuits, but there are difficulties in sourcing the necessary components. Attempts have been made to...
Fet Audio Mixer electronic circuit
This circuit combines two or more audio channels into a single channel (for example, converting stereo to mono). It is capable of mixing multiple channels while consuming minimal power. The schematic illustrates two inputs, but additional inputs can be incorporated...
Two channel audio mixer circuit design electronic project
This audio mixer circuit diagram electronic project is designed using a few common electronic components. The audio mixer circuit project has two input channels. The input signal can be independently controlled using the R1 and R2 variable resistors. The R3...
UNITY GAIN FOUR INPUT AUDIO MIXER
The circuit features four inputs. The voltage gain between each input and the output is maintained at unity by the relative values of the 470kΩ input resistor and the 470kΩ feedback resistor.
The described circuit operates as a voltage buffer or...
3 channel audio mixer (2N3904)
That circuit will provide an overall gain of one between the output and each input channel. Each input channel includes a single 0.1uf capacitor and 100-Kilohms resistor to provide an output impedance of 100K. The number of input channels to...
Audio Mixer with 2N3819
This simple circuit mixes two or more channels into one channel (eg. stereo into mono). The circuit can mix as many or as few channels as you like and consumes very little power. The mixer is shown with two inputs,...
Audio Mixer 6 Channel circuit
The main circuit of the 6-channel mixer consists of six input channels. Channels 1-4 are mono, while channels 5-6 are designed for music use. The number of input channels can be increased as desired. The output of each channel drives...
multi channel audio mixer using lm3900
The circuit includes a quad channel amplifier (LM3900) with microphone audio inputs and direct line inputs. By adding circuits in parallel, the number of inputs can be increased for various applications. The input is connected to the inverting terminal of...
Muti-channel audio mixer circuit based on LM3900 IC. Four channels
A simple multi-channel audio mixer circuit utilizing the LM3900 quad amplifier is presented below. The circuit features a four-channel quad amplifier (LM3900) with two microphone audio inputs and two direct line inputs. By paralleling additional circuits, the number of inputs...
