Audio Volume Control Attenuator with IR Control
The circuit provides both audio volume and input channel selection. 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.Raleigh Audio Line Stage – K & K Audio

30 april 12. Introduction. The measurement of speaker impedance by the hobbyist is done through the constant current method a high value resistor is placed in series with a voltage source (amp) and the speaker is connected from the resistor to ground.555 timer IC
The 555 timer IC is an integrated circuit (chip) used in a variety of timer, pulse generation, and oscillator applications. The 555 can be used to provide time delays, as an oscillator, and as a flip flop element.Derivatives provide two or four timing circuits in one package.Introduced in 1972 by Signetics, the 555 is still in widespread use due to its low price, ease of use, and stability.Circuit Zone Electronic Projects, Electronic ...
LM3886 is a high fidelity audio power amplifier IC capable of delivering 68W of continuous power using 4 Ohm speakers. LM3886 provides excellent S N ratio of 92dB and above as well as extremely low total harmonic distortion over the audio spectrum.nCUBE
nCUBE was a series of parallel computing computers from the company of the same name. Early generations of the hardware used a custom microprocessor.With its final generations of servers, nCUBE no longer designed custom microprocessors for machines, but used server class chips manufactured by a third party in massively parallel hardware deployments, primarily for the purposes of on demand video.AMB Laboratories
