Passive Volume Control Schematic

Volume control circuit for speaker 4 ohm or 8 ohm located in the another room far away.

Passive volume control schematic. 5 better balance control contributed by bernd ludwig. This gives limited control and helps reduce volume when a conversation starts. By using only passive components. Wiring a balanced stereo passive volume control and then sum three channels via 10k resistors and a 100k resistor to ground.

Dual linear potentiometer 2 resistors and 2 mini jack sockets. The resistors are very low value. It is 1 1 copy of better volume control from elliott sound products. Passive audio mixer w channel volume control.

My particular build features 4 stereo rca inputs mixed to 1 stereo rca output. This audio mixer mixes multiple audio inputs to a single audio output with knobs to control the volume of each channel. By using only passive components. A simple circuit you can build at home at low cost it uses just a rotary switch and wire wound resistors.

Hey did you came with some result with attenuator. This gives limited control and helps reduce volume when a conversation starts. You could easily alter this design to any combin. Note that the configuration described requires a high impedance load and the passive better volume control cannot be used in this circuit.

The interesting thing is it uses linear potentiometer along with load resistor to get smooth increase in volume level. I d logically go for this simple schematic. Bernd a reader of the audio pages has contributed a useful variation in this case a better balance control. The resistors are very low value.
