Live Sound 101: Sound System Design and Setup for a Live Band

At this point, buying preamps and discrete seperate audio components may well be getting you in too deep. There’s a lot of knowledge you need to have before you try to do anything in that route. Especially since you’re talking about 4-ohm speakers. Almost all consumer-level equipment is 8-ohm If you use different impedance equipment say 4ohm speakers with a receiver rated for 8ohms without taking into consideration all the factors, you can easily damage or destroy your speakers and the amplifier section of your receiver or discrete amplifier, etc etc It is possible to run mismatched equipment but speakers have to be hooked up in groups bye bye 5. There is such a thing as a bridgeable amplifier, but no, you can’t hook two high-ohm receivers together to run a low-ohm speaker. As for how much power you need, watts per channel is more than enough for most people’s home theatre. Go much above that and you’ll be getting the cops called on you for noise complaints. You were asking me about running this system for listening to mp3s and downloaded movies off your computer. To be brutally honest, you’re going way overkill. The Yamaha RX series receivers you were looking at were perfect for what you’re wanting to do.

How to Connect Speakers to an Amplifier

Jef Jon Fox An MP3 player is not going to have enough output to drive a pair of good loudspeakers unless they are “active loudspeakers” — which means they have their own built in amplifiers. Examples include the Wharfedale Active Diamond range, but there are lots more designed for use with portable music players.

If you have to buy an amplifier to drive the Wharfedales, then the question becomes a familiar one:

There are a number of ways you can hook up your computer to an amp/speakers/stereo, the easiest of which is to simply connect your headphone jack on your computer to your AUX component on your amp or stereo this kind of cord is easily found at almost any electronics store.

Tweet When it comes to volume, a speaker’s rated wattage is only part of the equation There seems to be some confusion when it comes to how “loud” an amplifier can get. When it comes to “volume,” many musicians only consider the amplifier’s power or wattage rating, and in general, more watts does mean “louder. Decibels and levels Decibels abbreviated “dB” are a logarithmic unit of measurement that pertain to a ratio between two numbers. Okay, I can see eyes rolling and glazing over, so I’ll simplify things, and attempt to keep the “math” to an absolute minimum.

With a logarithmic scale, you can’t just add numbers in the usual way—a doubled number isn’t “twice as much,” but rather, many times more. For example, dB is many times greater than 50dB, not just “twice as much. In other words, if one amp is generating 90dB SPL and another amp is hitting dB SPL, the second amp will generally be perceived to sound about twice as “loud” to the typical listener.

Wattage, power, and SPL So how many watts does it take to get twice as loud? Let’s imagine two amps—one amp rated at 10 watts, and a second amplifier rated at 20 watts. The watt amp is double the power of the watt amp, but doubling the power only translates to an increase of 3dB SPL. Remember, in order to sound “twice as loud,” you need an increase of 10dB, so while a 20W amplifier will sound noticeably louder than a 10W amp, it will not sound twice as loud.

Can I hook up 2 speakers per channel?

That is, in the one amplifier box, there are two different amplifiers. For the purposes of this article, we are talking about connecting multiple speakers to a single amplifier only, that is, either the left or the right, or any single amplifier. Of course you can connect multiple speakers to both the left and right amp of a stereo — you just need to follow the principles twice, once for each amp.

Multiple Speakers on One Amplifier By adding an extra speaker to the output of an amplifier, you are adding to the load of the amplifier.

Oct 16,  · You then hook the speaker outputs from the sub to the front left and right speakers. There’s an adjusable crossover knob on the sub to split the bass off to the sub and the mid-bass/high frequencies to the speakers.

A stereo system is a central part of most home theaters. Purists gush about the sound they can get from their stereo receivers and speakers. Consistent advancements in the music industry have made it possible to connect other playback devices besides just a CD player. MP3 players have established themselves as an especially practical option. An MP3 player offers room to store hundreds or thousands of music titles in a tiny space. If you’re having a party at home, it’s possible for any guest in the room to play his or her own music at the drop of a hat.

If you want to take advantage of an MP3 player in your own stereo system, there are a few things to look out for.

How do I Connect Multiple Speakers to my HiFi Amplifier

I’ve had friends run Kove 12″s, 4 doors and 2 tweeters off a 5 channel amp before. I doubt it got the sub to it’s RMS rating, but it sounded pretty good and got the job done, I just wouldn’t recommend it like that. I want to amp my tweeters and 6X9’s and my sub, different amps for the subs and speakers I don’t understand how you do it because the speakers have to be hooked up to the head unit right?? The power lead connects from the amp positive terminal to your battery – you will have to route the leads under your carpet.

May 17,  · You want box speakers (the ones that just have the – and + wires hanging out the back), if you don’t have any you could try Goodwill (you can usually get them for like $20 over there). Connect them to The Amp.

September 28, Grant Clauser 17 Comments This is a question we receive all the time, and one I bring up myself whenever I speak to people at Sonos? Where are the Sonos outdoor speakers? At the moment there are none. Other companies have outdoor music solutions. You can also use outdoor and portable Bluetooth speakers if wireless solutions are your top priority. The Soundcast Melody is an Electronic House favorite because it does a great job and producing full, deep bass and throws out a degree soundfield from one portable unit.

It can also cover a large area. The best way to use your Sonos system in your backyard is to go with a Sonos Connect: AMP and wire it to some good outdoor speakers. First, the Sonos Connect: AMP, which is a 55 watt per channel stereo amplifier with Sonos connectivity built in. You could also use a Sonos Connect not the amp version and add a separate amp, such as this AudioControl Rialto read a review here. Want your music to move with you?

Connecting subwoofer to a stereo-amplifier without pre-out for sub? (total beginner)

How to install an Amplifier: Disconnect the battery terminals: Run the power cable from the battery to the location of the amp or distribution block. To read more about running wires, click here If you run it through any sort of sheet metal, be sure to protect the power cable with a rubber grommet, or some other protective device. Be sure you have plenty of slack at both ends of the cable. This will make your life easier, trust me!

That said, an amp has many benefits and is worth the time to find a good one that will give you what you want and match your speakers well. However, an amp might expose your Sony speakers for the under-performers they are.

Speaker Connections for proper impedance match A note about amplifiers: You should always use the recommended load for your amplifier. However, if you must use a load other than the recommended load, here is a short guide. Most solid-state amplifiers would rather look at an open circuit no speaker at all than a load. Therefore, you can usually use a load that is higher than the recommended load. Do not use a lower impedance load, as this could cause serious damage to your SS amp.

On the other hand, most tube amplifiers need a load to avoid transformer or tube socket damage. If a mismatch can not be avoided on a tube amp, it is better to go towards a lower impedance rather than too high of a speaker impedance. This may stress the tubes some, but, tubes are cheaper than transformers. As the graphic shows, you connect the positive wire to speaker A’s positive terminal, connect a wire from speaker A’s negative terminal to speaker B’s positive wire, and then connect the negative wire to the negative terminal of speaker B.

How do you wire speakers and tweeters off of a 2 channel amp?

Is there any audio driver required after connecting it into computer? The moron couldn’t hoo up my sisters home theater. I had to sit him down and take over. The guy is an idiot. Dave Hilling II September 1, at 7:

Using Your Amp Without Speakers Connected: Here’s When You Can and Can’t September 09, 3 Comments Whether you’re at the studio using your amp head as a preamp or jamming with headphones at home, it’s very important to know which circumstances require that you connect speakers to your amp.

How do you hook up a 1 farad capacitor to your amp? Answer 1 You first have to determine which side of the cap is positive andwhich side is negative. You run a wire from the negative side tothe chassis and for the positive side you run a cable from thebattery to the terminal and from the terminal to the amp.

Be careful not to mix up positive and negative on the capbecause it could explode and cause damage. Answer 2 Because the capacitor is used to filter changes in supply voltageto the amp, the capacitor should be as close to the amp aspossible, and connected with heavy wiring. The capacitor also actsas a huge reservoir to supply lots of current as the amp signalhits high levels.

By providing plenty of current when it is needed,distortion in the sound is minimized. The key is lots of capacitance, as close to the amp as possible,and thick cables capable of carrying lots of current. Answer 3 Be very careful with that thing. The current output of a capacitoris the product of capacitance, in this case 1, and the change involtage with time. Thus, if you do something to cause a quickchange in voltage with that, you will get a very large currentspike, possibly hundreds or even thousands of amps.

Also note for this reason you should really pre charge capacitorsof this size. Let’s say you have 1 ought wire run from your batteryto the cap, with a resistance of. I actually have noidea what the resistance of your wire is, I just made that up forargument’s sake When you connect the discharged capacitor, you arecausing an instantaneous change in voltage.

Can you hook up a sub to a 2 channel stereo system?

Many guitar amplifiers and small stereos come with amplifiers pre-attached to speakers, so there is no need to connect those. However, most high-end guitar amplifiers have speakers sold separately, or allow you to connect to speakers in addition to the one that came with the amp. Similarly, most high-end home stereos require you to connect the speakers to the amplifier manually.

Connecting a Speaker to a Guitar Amp Locate the speaker output jack on your guitar amp. Usually, this is a quarter-inch input hole, though some guitar amps also have speaker output jacks for Speakon cables or XLR cables.

Feb 20,  · With the first alternative, though, you would have to have the headphone amp powered up in order to listen via speakers; I’m not certain but I suspect that wouldn’t be necessary with the second alternative (i.e., using the loop output).
