The VOX-AT10P is a low cost single-gang, 10W, ten-step, continuous rotary, audio level attenuator with an OFF position used to attenuate audio power to any number of loudspeakers, up to 10W load. For use with 25V or 70V distributed audio systems. (And a ladder stepped attenuator would cost twice as much as the series attenuator.) The small price we pay is a -3dB insertion loss, because of the shunt attenuator. Since most balanced signal sources already provide far to much voltage output, hence the need for a volume control, the -3dB loss is not a problem.

    Attenuator circuits are very useful for whenever we need to decrease the strength of signals. Think of applications such as volume control. If the music is too loud, then we need to attenuate them in order to get less volume. The music comes to our ears through audio signals. AT-4000 Series Attenuators Design with ergonomics for the human hand in mind, AT-4000 Series Attenuators’ control knob comes in a size that provides comfortable grip and excellent control with every turn.

LUXMAN's original LECUA 1000, a stepped fixed resistance attenuator, is used for the volume adjustment system, a major feature of this new control amplifier. The 88 step range allows for more precise volume adjustment. Jul 21, 2019 · Since there are other kinds of attenuators that are also called "active," I prefer to call it an offset attenuator. That term describes how it solves case leakage by offsetting the signal frequency. An offset attenuator consists of a local oscillator (LO) connected to a diode mixer through the attenuation control.

    Nov 05, 2013 · The advantages of a stepped attenuator are the possibility of better sound because of the parts quality. The downside of this arrangement is the volume is controlled in a series of fixed steps and you may or may not like the step level. There are pots that can come close to the performance of a stepped attenuator, but rarely do they. The Line Stage provides an interface for a volume control.

The Glasshouse Stereo Stepped Attenuator (Elma A47) can be used in conjunction with the Remote Control module, the Remote Audio PLUS with LIN Motor. Perceived volume isn't linear anywhere in the amp, anyhoo. Since audio L-pads are fairly common, I'd expect the manufacturers have a handle on that aspect, though. Personally, I think most guitar players don't expect their attenuators to function seamlessly as another volume control.

LittleKnob passive studio monitor controller, designed for DAW signal routing volume control of monitors or speakers without compromises – due to dual stereo solid state network. Both (L/R) sides are separated, without any electrical relation (connection) between them. A stepped attenuator is geeky audio term for a complex multi-pole mechanical switch with a ton of resistors attached. It uses a big rotary switch to select discrete resistor pairs usually corresponding to a few dB change in volume per step.A line-level attenuator in the preamp or a power attenuator after the power amplifier uses electrical resistance to reduce the amplitude of the signal that reaches the speaker, reducing the volume of the output. A line-level attenuator has lower power handling, such as a 1/2-watt potentiometer or voltage divider and controls preamp level ...

Required fields are marked * I had sort of discounted a traditional volume pot, and was thinking in terms of a stepped attenuator with some precision resistors in it's place. But in researching these I discovered people were saying transformer attenuators are a particularly neutral sounding way of adding a volume knob. If your preamp has a volume control that has the volume come on too quickly you can use the attenuator as a "master level" control for your amp. I will probably be offering the stepped attenuator as an option with the kits and wired amps that I sell in about 2 weeks but the attenuator may be used with any Dynaco ST-70 amp. Mar 26, 2012 · Repeat the measurement parts of step 17 and adjust with the muti-turn pot until both optocouplers have the same resistance. To test the attenuator plug in your source to the attenuator and then into an amplifier with it's own volume control set at a reasonable level. However, it's clear that low-distortion audio gain cell with a wide control range is a very significant design challenge, and not at all an obvious way to make a volume control. Carbon composition, carbon film, conductive plastic potentiometers, or switched resistor ladders all make for a much more straightforward solution.Available as master volume control with 60dB attenuation range (1, 2, 4, 6, 8 decks) and as individual channel fine adjustment control with 0.5dB level change between each step (only available with 1 deck).
