    Whats a L-Pad????

    Someone told me I could use a L-pad to pad down my component speakers. Sorry for sounding stupid, but what is a L-pad? Thanks

    I have no idea what an L-pad is, either. I'm only replying to say.. that is one of the most ****** rides anybody here has! Not sure which I like more... the HU or the 600HP....

    Got some pics?

    Re: Whats a L-Pad????

    Here is a definition. Ask Josh, Geo, Loyd, someone else to explain what it means exactly... :p

    Attenuator or Attenuator pad Electronics: A passive network that reduces the voltage (or power) level of a signal with negligible distortion, but with insertion loss. Often a purely resistive network, although any combination of inductors, resistors and capacitors are possible, a pad may also provide impedance matching. [Compare with fader and crossfader.] Pads are referred to by the topology of the network formed, with the two most common being an L-pad and a T-pad:

    L-pad A two-leg network shaped like an inverted, backward letter "L". It usually consists of two resistors that are fixed or adjustable. A true variable L-pad consists of two variable potentiometers that are ganged (tied) together. The ganged sections work to provide either a constant input or a constant output impedance regardless of the attenuation setting. Since modern analog audio electronic circuits consist of stages characterized by very high input and very low output impedances, the term is now broaden to include all L-shaped networks without the requirement of providing constant impedance to the source or load. Volume and level controls are common examples.



    Igitur qui desiderat pacem, praeparet bellum -- Vegetius

    "I told her about my conversation three years ago with the political leader of Islamic Jihad in Gaza. "What's the difference between suicide, which the Koran condemns, and martyrdom?" I asked. "Suicide," he replied, "is done out of despair. But remember: most of our martyrs today were very successful in their earthly lives." In short, there was a future to live for--and they detonated it anyway."

    An L-pad is a fancy volume control. People use them to control the volume of remote speakers in PA systems. I can't think of any reason to use one with a car system. Why did your friend suggest one?

    We use one many years ago to adjust the volume on a center channel speaker. Worked great.
