The tech world has finally coalesced around a charging standard, after years of proprietary adapters and ugly wall-wart power supplies. Ten to 15 years ago, you always had to make sure you had the correct power supply for each of your gadgets. Not all USB chargers, connectors, and cables are born equal. Sometimes, one USB socket on a laptop is seemingly more powerful than the other. In almost every case, your PC is the host, and your smartphone, tablet, or camera is the device. Okay, now the numbers. A regular USB 1. In terms of actual current milliamps or mA , there are three kinds of USB port dictated by the current specs: In the USB 1.

Email Shares 52 We get a lot of questions on our electric wiring articles from folks tackling electrical projects in their own home.

One of the questions I get asked frequently is how to design a speaker cab. I’m not the best source of info in the world for this, so luckily Michael Sabolish has come to the rescue with an excellent write up .

Do you need really huge speakers, and are they worth it? Yes they are…at all costs. The bigger the better! Monstrous, gigantic speakers sitting three feet away from your face and pumping out dB of ear-bleeding sound is exactly what you need! Just ask your spouse or the person sitting next to you. They ran out of the room screaming?

The truth is, I once downsized my speakers when I went from a larger room to a new home where my theater needed to shrink. If you want to understand anything about room acoustics, remember this: Loudspeakers always interact with the room in which they are placed. That means that if you place really large speakers in a small room, the room is going to have an effect on the sound produced.

About Amps Finding the right amp for your bedroom and smaller clubs, can be a challenge. During the last decade, the market has been flooded by affordable tube amps in all price ranges and while most of them will cover your basic needs, there are some distinct differences that will have an impact on your tone. The large tube stack phenomenon started in the late 60s, when bands moved to bigger stages and needed more volume and wattage. Prior to this, a small combo would do the job nicely.

You dig oddball guitars and strange, rare equipment. Sure, a Fender Telecaster is a great guitar (I have a , and I love it), but there’s something about the weird ones that pulls you in or you wouldn’t be reading this newsletter.

I feel this information will be important to the owners of these superb amplifiers. There’s very little editing: I want to call attention to both you and owners of the Canary CA , a moderately inexpensive vis a vis very expensive premium B tubes way to kick up the performance of these amps. Having just brought another pair of them into my showroom, I decided to leave the stock Electro Harmonix B as is. For less money than a pair of KR B’s these amps take 2 pair each keep in mind , the changes were breathtaking.

Transients, soundstage, and articulation were noticeably improved. I thought your readers might be interested to know that, although these amps benefits from premium B tubes, these changes are a great cost effective compromise. Its power rating appears “modest” 22 watts, 90 watts peak , and it does not break any new sonic grounds, but the “good news” is that this amplifier can virtually equal most amplifiers we know of in most areas of music reproduction. This means that it has much of the pure, natural, immediate and liquid qualities of the finest of the ultra low-power under 10 watt single-ended amplifiers, while still sounding as “gutsy”, dynamic, and controlled as many more powerfully rated amps.

Despite the standard “BS” regularly written in audio magazines, exceedingly few other amplifier have ever been able to legitimately make this claim in the past. It is exceptionally well built and it is also ultra-quiet during operation.

Big Picture Big Sound

Jack has hinted that he’s started writing – “I wrote a song yesterday, the last couple of weeks, i’ve just been endlessly thinking about this title: Let’s Play the Victim. I definitely have a lot, a lot of songs together for another White Stripes album. I just don’t know when we’re gonna record it yet. I just have to take a break from the band for a second, because it’s just been consuming — all-consuming, you know?

What size speakers do you need? If you place large speakers in a small room, it’s going to have an effect on the sound. Same goes if they’re too small.

In reality, a lot of these variables are mutually exclusive: If you want maximum power output, be prepared to pay more for the drivers and sacrifice some frequency response. Keep these things in mind as you read over the next sections. A Note on Speaker Selection Don’t skimp too much on the speakers: However you can have all of the above qualities without spending a fortune.

A word to the wise: However, like most older things in the music industry, they have a “magic” premium attached to them, and hence you must pay more to get them. Try and stay away from speakers with cloth accordion or treated paper surrounds for any designs other than open backed. The surround on these speakers can be a large source of air leaks in sealed enclosures, which results in lowered efficiency.

Remember, each 3-dB increase in efficiency results in twice the apparent sound level at a given power input. Most speakers for instrument use are very high in the high 90’s, and some are over for the wattage they accept.

There are several sections in this website that you should read regarding track wiring. This section, Part II, covers track wiring.

It is remarkably compact and portable for a live sound system with this much capability. And thanks to leading Yamaha digital technology, the EMX CF also includes a number of innovations that make it easier than ever to achieve top-class sound in just about any venue. An impressive power output of watts per channel means it can handle fairly large audiences, indoors or out. Versatile input configuration adapts to varied source requirements The EMX CF has a total of 16 input channels-eight for monaural microphone or line input plus four stereo pairs.

The stereo channel pairs can function either as monaural microphone inputs or stereo line inputs. This system gives you extra microphone inputs if your sources are mostly microphones, or if you need to handle more stereo sources, the EMX CF will comfortably handle four pairs in addition to eight mono mic or line inputs. Advanced channel EQ 3-band EQ is available on all input channels, but extra versatility is provided on the eight mono channels with mid-frequency sweep controls. The mid EQ center frequency can be continuously swept from Hz through 5 kHz so you can precisely pinpoint frequencies in the critical midrange.

But it does feature a range of inputs and outputs that allow it to be expanded with external gear or integrated into larger systems.

It looks great but sounds terrible. So I picked up a sound bar. It’s a Boston Acoustics TeeVee 26 and came with a subwoofer too.

Nov 09,  · Hi, 50 Watts should be enough to get the UB5 speakers sounding pretty good, however you need to make sure that the amplifier you are using is designed to power 4 ohm speakers.

So this approach may not work for you. I use 10 AWG for my G, again not for any electrical reason, but for mechanical strength. It will take a lot longer for a buried 10 AWG to corrode through. If I hit it with a shovel, I am not likely to break it. If you are an ohm counter or live life three places past the decimal point, click here for a detailed AWG vs. After running my track and wire resistance tests , I have amended this section.

How far apart can I place my feeders? But, how many of you can go even 10′ before hitting a new block, usually caused by hitting a rail switch?
