Tighter, Punchier Bass

February 7, 2018 by Ben Stowe, CTS
One of the biggest mistakes I see audio professionals of all walks making is that they have high-frequency boxes and subwoofers out of time-alignment. Their system is sabotaged against them and they don’t even realize it. To try compensate for the poor result they just continue to pump more power into their speakers and in many cases cause component failure. The solution is incredibly simple and the results may astound you. The problem that we have here is simply that frequencies around the crossover point are arriving at different times which is causing power alleys, nulls and phase shifts at those frequencies. To correct this, we simply need to time-align those loudspeakers. In plain English, we need to slow down the sound coming from some of them to match the sound coming from the others. We can’t s...

Managing Audio Delay

January 24, 2018 by Ben Stowe, CTS
Sound travels fairly slow, with an approximate speed of 1128 feet per second (this speed changes with temperature and humidity, but not frequency). This can impact how we deploy our systems. One of the ways it impacts DJs the most is during events where additional speakers are needed for coverage. For example, if we deploy speakers into a fairly long room and have one set of speakers near the head table of a wedding and another set 100’ back in the room to provide adequate coverage for people back there to hear we have a serious delay problem. The sound from the speakers at the head table will arrive approximately 90 milliseconds after the sound from the speakers placed 100’ back. This will create a substantial echo, and will greatly decrease the intelligibility of speech. Speech clarity isn’t the... [read more]

DJ Tips In Under A Minute: Measure And Mark Off Your Speaker Stands.

January 4, 2018 by DJ Jay
All right. DJ tips in under a minute, speaker stands, we all have them, we all use them, but I took out this and then this, a silver sharpie today and decided I'm sick of these things, guess working where they're supposed to be. So I measured out where I would normally have them on my events and just put markings every foot. So I don't know if you can really make that one out, but there is -- yeah, there it is and then down here. And that way next time I do an event, I'll know that the stands are the exact same height, exact same size. Maybe your speaker stands come with sort of markings throughout, mine didn't and don't and I just want them to look the same. So DJ tips in under a minute, measure and mark out your stands every foot or so that you can always have them be the same height. In under a minute. ... [read more]

Ohms, Amps, Volts and Watts

December 13, 2017 by Ben Stowe, CTS
Electricity is the lifeblood of the systems we run, so having a basic understanding of it can be very helpful for engineering and operating reliable systems. Moreso, it can be essential in troubleshooting them when things go wrong. While there are a great many electrical terms, four fundamentally important ones are Ohms, Volts, Amps and Watts. These are all units of measure and they are intertwined in electrical relationships known as Ohm’s Law and Watts Law. Ohms law tells us that Ohms are equal to volts divided by amps, while Watts law tells us that Watts are equal to Volts x Amps. Using these two basic formulas, we can ... [read more]
