Passive volume control

Balance control , mute, brightness control for the display, night listening mode, sleep function. Using together with the IRotary input selector car other smart functions like AV pass, automatic input level matching max. A passive volume control is a passive device (no active electronics and therefore no power supply required) that replaces the traditional preamplifier.


Today, many signal sources such as CD players have sufficient output level to drive most power amplifiers directly. The cheapest can be found for around euros, more expensive cost hundreds.

Mine below euro, but it cost me a lot of time, more than I expected. This gives limited control and helps reduce volume when a conversation starts. The resistors are very low value.


George , a passive is a volume control. Long interconnects can give you problems as the source must drive the amp with no help from a pre-amp. With some source and amps you would have no problem with meter interconnects.


It all depends on many things, speaker used will also have an effect on how it works out. A passive preamp is often all that is needed between a signal source and a power amplifier.

The precision stepped attenuators used in Goldpoint passive preamps are more transparent sounding than the typical potentiometers found in other preamps - active or passive. When you stop and think about it reducing voltage (i.e. volume) means you are squeezing all that energy through a type of electronic funnel. In fact you are quite literally dumping (shunting) some of that energy into the ground. SYS stands for switch your, er. Sys is a simple, 2-input passive preamp.


Just a 2-way switch and a potentiometer. Why would you want such a thing? The LDR is exceedingly transparent and has remote functions for volume , balance, display brightness, configurable impedance settings for different system matching, switchable.

All Your Music Needs In One Place. A simple circuit you can build at home at low cost it uses just a rotary switch and wire wound resistors. The interesting thing is, it uses linear potentiometer along with load resistor to get smooth increase in volume level.


Passive volume control. Arguably, the best kind of knob. And certainly the most enjoyable part of any decent audio gear - you can tell a lot about an amplifier or DAC by the texture and rotation quality of it’s primary enloudener.

It uses light dependent resistors(LDR) to give you an exceedingly transparent volume control. I have tried all kinds of volume pots and also a transformer volume control preamp but this is the best. It has inputs, two outputs, and remote control with balance, volume and impedance adjustment.


When the PVC PC volume control is set to maximum, it outputs the same signal level that it is receiving. Polsen VCP-Overview. What’s the convenience of having an analog volume control over the built-in volume control in most interfaces? Most important is the fact, that by turning down the volume with the built-in volume control, the bit depth will drastically decrease, as most interfaces will reduce volume in the digital domain. Volume Control About the Volume Control.


This Audio Mixer mixes multiple audio inputs to a single audio output, with knobs to control the volume of each channel. My particular build features stereo RCA inputs mixed to stereo RCA output. You could easily alter this design to any combination of jacks that you need.


This mixer is passive , meaning it requires no external power.
