Speaker Signal Delay Calculator 1.02 is an effective audio recording tool which allows you to calculate the amount of signal delay needed to time align the subwoofer and the two separate arrays of main speakers in the sound system at Abundant Grace Church of Troy Michigan. The standard method for improving system synchronisation and intelligibility is with the use of signal time delay units. Nowadays, these devices use a full bandwidth digital processor which 'holds up' the signal to the secondary speakers for a fraction of a second until it is in sync with the main source. May 11, 2017 Since there’s really no possibility of a single speaker that plays the entire audible range with low distortion and similar dispersion at all frequencies, we’re stuck with them. Here’s the rub. Crossovers do alter phase. However, phase in the acoustic signal from the speaker changes every time the acoustic output changes direction. Adding Delay. There are several ways to add delay to the ancillary speakers, depending on your PA system. Many amplifiers and powered speakers designed for complex, multi-speaker setups come equipped with digital signal processing (DSP) that includes onboard speaker delay. May 17, 2009 I find it easier to only work with signal to 2 speakers at a time so for a 3-way speaker I mute the W to find the delay between the MR and TW. Any delay then established for W to MR also need to be added the TW so the delta time of MR to TW remains the same.
Extron provides a series of audio calculators that sound system designers, engineers, and technicians frequently need to access, such as determining amplifier power requirements, converting between dBu and dBV or volts, or estimating the loss in sound pressure level with an increase in distance.

Nothing to be concerned about I think. The > difference in signal level, because of the extra resistance of the 3 meters > extra cable, would be much bigger, but also way below the hearing threshold. I am pleased to report that, using mathematics and physics, I can confirm Luc's calculations. A 10 foot difference in the length of a speaker cable is approximately equivalent to an acoustic delay corresponding to 0.003 mm of displacement. Given that a (my) human hair has a diameter of about .05 mm we can conclude that C. could use speaker cables that differ by MORE than 100 feet (ten times greater than he asked about) before the cable length difference would approach the acoustic effect of moving the speaker (or listener) just a hair's width. In other words there would be no chance of this ever being audible.unless you are certain that you can hear the difference in moving one speaker one tenth of a hair's width. :-) But.the difference in DC resistance of C.'s unequal cables might begin to approach audibility thresholds depending on wire gage and the impedance characteristics of his speakers. I still wouldn't worry about it unless this were a serious research project where the results were intended for publication and would be subject to (razor sharp) anonymous peer review. For any of the popular audio magazines, on the other hand, you could say anything you wanted.mystical explanations are quite welcome in the popular press as they constitute a smoke screen of disinformation behind which dishonorable manufacturers hide to sell fantastically over priced products with a straight face.and buy lots of ad space. As always, the joke is on the unsuspecting consumer. My advice to all audio consumers is to be suspicious of unsubstantiated advertising claims, .be VERY suspicious. Cheers!
