How far will a wireless microphone transmit reliably? Mose wireless microphones use radio signals for transmission. A radio signal is transmitted at a certain signal (power) level, but received at a much lower level. Radio signals are attenuated (decrease) as they pass through air or other media.
When wiring up your new sound system, it’s easy to think that cable is cable wherever you go; just make sure A goes to B, and the signal chain lines up, right? Not necessarily. You can have the best of the best when it comes to your speakers, amplifiers, mixer, and microphones, but if you’re not using the right type of cable, you may be sorely disappointed in your investment. In this article, we are going to look at the differences between wires, what it means, and why it’s so important.
In the hands of sound professionals, equalizers can be effective tools for combating feedback. But in facilities where experienced personnel are not always available it may be wiser to employ other means. The reasons and solutions are discussed below.
Feedback occurs at a specific frequency that is emphasized more than others. It stands to reason that if you can locate that frequency and reduce it’s level, you can stop the feedback. Equalizers are ideal for this purpose, so in this section we’ll look at how graphic equalizers are used for feedback control.
For both stereo and surround mixing, your position in relation to the main front speakers – the “sweet spot” as it’s often called – should be one apex of an equilateral triangle. In other words your distance from either speaker should be the same as the distance between the two speakers. The speakers should also be “toed in” to the corresponding 60° angle so that the drivers are aimed directly at the listening position. The height of the speakers should be such that the tweeters are roughly aligned with your ears (this is because high frequencies are the most directional).
So you want to feed sound from your main sound system into more than one other room, and you want local volume controls in each room, right? You’ve called ProAcoustics, and they’ve recommended to you a 70-volt Distributed sound system. It all looks well and good, but there’s one thing standing in the way – how do I wire this up?
We’ve posted this article to help explain some key points of a 70-volt distributed system, from definitions of terms to wiring (diagram included!), and even some tips on selecting components.
In the past, having sound throughout the home was an option for the wealthy. Nowadays, though, having a Whole House Audio System that plays and controls the distribution of music in multiple rooms is easily attainable, and isn’t necessarily as expensive as you may think. With the right gear and proper know-how, having a multi-room/multi-zone Home Audio System is easier than ever. However, wiring one together can quickly become a headache for the underprepared. We at Pro Acoustics are always happy to help you out; so much so that we’re posting some help on ways to go about wiring these Muti-Zone Home Audio Systems.
