Relay attenuator

WebJan 25, 2014 · Attenuation. A muting transistor has very low ON resistance –in the order of 1Ω. With a 1K audio signal source resistance, it provides 60db attenuation –this is much better than the best analog switches in the ON mode. In audio mixer applications additional attenuation (perhaps 80db) is recommended to completely silence unused inputs. WebSep 17, 2024 · The basic passive attenuator acts as a resistive element that reduces the incident signal by a certain amount of signal energy. Hence, attenuators are often designated by the decibel (dB) drop the attenuator provides. Basic passive attenuators are both absorptive and dissipative, in that they absorb incoming signal energy and dissipate …

Passive Attenuator – Stumped with this simple circuit

WebRelay based stepped attenuators just use lots of switches to switch in and out discrete resistors. It's a good way of doing volume control, but very expensive and space consuming which often leads to companies designing them with large steps to reduce component count (I've seen as large as 2dB per step which is absurdly inadequate). WebNov 6, 2024 · Thanks a lot for the replies @ALLO_audio_boards and @allo.com!And sorry for my delayed response, it was out of a lack of time rather than a lack of interest.

WebJul 19, 2024 · That stepped attenuator looks like a "ladder" (may have the wrong terminology) attenuator - this is where there is a voltage divider per step performing the attenuation. Most relay attenuators won't do this - as the number of relays required will be quite large, so will most likely be a series design. http://tkd-corp.com/en/technology.html
