PSW Staff 06/17/09 09:43 AM, 0 CommentsOhm’s Law states the relationship between current, voltage and resistance. Watt’s Law states the relationships of power to current, voltage and resistance. Enter any two known values and press “Calculate” to solve for the others. Fields should be reset to 0 before each new calculation. Equations used to calculate the data: V = IR P = VI Where: I = current P = power R = resistance V = voltage View this story

Thursday, June 11, 2009PSW Staff 06/11/09 08:11 AM, 0 CommentsThis calculation will give you the ratio, in decibels, between two voltages. For example, you can calculate the gain needed to raise the output level from 0.775 volts to 1.4 volts. You can also use this to calculate how much attenuation you need if, for instance, you have a 2.0 volt input level and you need to attenuate it to 0.2 volts to prevent input overload. Enter any two values and press “Calculate” for the remaining value. Press “Reset” before… View this story

Tuesday, June 02, 2009PSW Staff 06/02/09 09:55 AM, 0 CommentsFigures calculated for various program material use estimated duty cycles, taking into account the typical crest factor for each type of source material. The choices typically available in the calculators are as follows. Pink Noise: Duty cycle of 50%. Dance: Duty cycle of 40%. Typically highly-compressed, low-frequency material at very high levels. Hard Rock: Duty cycle of 30%. Full-range, continuous rock music at concert levels. BGM: Duty cycle of 20%. Background music, typically used in business music applications at low… View this story

Dave Dermont 05/15/09 10:42 AM, 0 CommentsI can’t believe I have been at my new house gig for a couple months now. Time sure flies when you’re having fun! I wasn’t there when they brought in the gear and set it up, so some things are not the way I would have set them up. The mixer is on top of the outboard rack, like you’d do with a portable rig. Bending down behind a rack is not the best way to hear the tweaks you’re… View this story

James Cadwallader 04/17/09 10:09 AM,A few nights ago, I attended the gig of a friend of mine who plays guitar. He’s a great player and a pretty cool guy. Sound-wise, there was a lot of stage wash that helped make the room sound muddy, and the house mix wasn’t doing much to help bring some presence and clarity to the whole picture. I took a peek at the console and was glad to see the main fader at unity, though the submix faders were… View this story

Ron Huisinga 11/25/82 01:04 PM, 0 CommentsThis article is provided by New Life Communications. As you visit other churches for weddings or other reasons, you probably have noticed a number of different sound system designs. Some churches have column loudspeakers on the front walls. Another church will have many loudspeakers on the side walls. There are churches that have loudspeakers in the hanging light fixtures. Others have many loudspeakers mounted under the pews. It is apparent that there are many different approaches to providing a… View this story
