Stepped attenuator volume control

  • 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 ...

  • Nov 10, 2012 · Attenuators have worked well for me as long as I don't try to attenuate the volume too much. At 2 or 3 db of attenuation the tone doesn't suffer too much. If you try to take a raging Marshall down to bedroom levels the tone will suffer.
  • May 15, 2014 · Another alternative used in previous work is convex optimization. 10 Convex optimization is a very powerful tool but is only viable for convex problems, and the control of many types of dynamic attenuators, including the translating attenuator and the double wedge attenuator, appears to be nonconvex. (Control of the perfect attenuator and the ...

  • 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.
  • 10 Watt Potentiometer Volume Control The preferred method use controls which are specially designed for 100V line operation (attenuators) and simply wired between the amplifier and the loudspeaker. The maximum power ratting of the volume control must be observed and not exceeded, otherwise damage to both control attenuator and amplifier can occur.

  • 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.

  • May 24, 2007 · Relay based attenuators offer a number of advantages, most notably the amount of steps possible. Many give you 64 or more steps, which would be virtually impossible in a stepped attenuator.
  • Jan 04, 2012 · Thanks for correcting me, albeit I may of not made my post clear. I love digital volume controls, they're more precise than a Potentiometers and cost a significant less amount of money than a stepped attenuator. The M-DAC uses the ESS Sabre 32bit chip - well one of them. This means when reducing the volume it is starting at 32 bits of data.
  • Either a standard 10K to 50K stereo audio potentiometer or K&K Audio’s shunt attenuator can be used to control the volume. (see Stepped Shunt Attenuator below). Advanced Minimal Reactance Power Supply circuitry is incorporated into the Active Output board is designed to work with a Lundahl LL1683 power transformer.
  • Jun 09, 2015 · The same stepped attenuator on two different systems will have smaller or larger real-world volume adjustments per notch, making them more or less satisfactory to use as a fine adjustment control. If your volume knob never gets past 30%, or 9 o'clock for the horologically inclined, then your system probably has much more gain than you need, and ...
  • We, however, believe that the means of signal attenuation (the volume control) is the most critical to the overall sound of a preamplifier. Most designers use resistor attenuators for volume control. We have used resistor attenuators with high quality resistors (Vishay, in the past, felt unsatisfied from the character they induced in the signal.
Java point 824 position stepped attenuator! ... Stepped Atenuator Volume control. Andrew_Whitham. April 13th, 2013. 24 position stepped attenuator! The stepped attenuator is available in the following impedances: 50K 100K and 250K. We also offer the mono version. The Glasshouse Stereo Stepped Attenuator (Elma A47) can be used in conjunction with the Remote Control module, the Remote Audio PLUS with LIN Motor.
Therefore, a step attenuator is often employed in high-end audio products in an attempt to match two channels precisely. FEATURES • 1/4 –metal-oxide film resistors with tolerance 1%. • Ladder-type structure and total 24 positions. • Logarithmic scale attenuation start from 75dB to 0dB (5dB/step for first three

A stepwise volume control is implemented with a set of small relays and resistors. In a high-end audio system, a noticable sound improvement over potentiomeneters can be obtained, also over ’audio grade’ potentiometers. Clearly, the IR remote control provides convenience over solutions with stepped attenuator rotary switches.

  • The function of this automatic volume control circuit is to amplify signals without distorting its dynamic compression. The amplitude differences in the signal are levelled off and the disturbing effect vanish. With this tehnique, overcompensation in the volume is avoided. Mar 02, 2011 · Stepped attenuators can be set up in a series, shunt or ladder configuration through a network of fixed resistors and a rotary switch. There's an excellent comparison between these three configurations on DIYAudio by Arn Roatcap, Inc. A series attenuator (the most common) is the cheapest and has the fewest parts, it uses all resistors up to a ...

  • Nov 05, 2020 · The amp is then followed by a series of 4 attenuators that can be switched in and out using RF relays suitable for use into the VHF bands. This means I have variable gain from -23dB to +20dB in 3dB steps. More than goof enough for the kinds of girls I go out with. So I knocked up a test board to put it all to the test.
