Low Noise 4 Channel 3.5mm Pro Audio Passive Sound Line Mixer Live Studio Console. Many have asked us for a remote control for our Django TVC passive preamp. Clearly, the IR remote control provides convenience over solutions with Provided that a high quality volume control is used, a passive preamp is often the easiest and cheapest way to reach high-end sound quality. A better solution is a buffered volume control which would have an opamp one either side of the pot, giving the source a steady, easy, load and the output would have a low impedance to drive whatever amp. The switched attenuator comes fully assembled and uses 1% precision metal film resistors on a make before break 2-pole (stereo) 24-position switch. My first decision was to decide how I wanted to wire up the control. Wire up the ground to the input RCA.

The circuit provides both audio volume and input channel selection. I was reluctant to include it in an amplifier or preamp project without knowing how I would like the result. 10. As mentioned, the possibilities here really are endless, but this comes in particularly handy when you're attenuating a signal that doesn't hav Not only is the Digispark small, but it is cheap! US $1.22. Your design might be more or less complex, as your needs require: 1. If all you need is a volume control for listening to music, just use a pair of 3.5mm jacks and get rid of the switch. Music In -> Volume Pot -> Music Out. Passive preamps have gained popularity in high-end audio circles. The design here pulls from the design for a passive monitor controller from JLM Audio. 3.
