Setting up system w/multiple amps

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. That is, two speakers is double the load of one speaker. Most amplifiers can cope with a load of two speakers. Similar to a passenger on a small motor bike: However adding more than two speakers will normally overload the amplifier. Similar to the motor bike example:

One-Wire Alternators: Are They Better Or Just Easier To Hook up?

Close the switch and you short the supply. What “goes on the end” is of course the power feed, a plug for 12v molex or onboard header. The switch should be in the red lead right after the positive side of the source, with the reds of all the LEDS tied together after that; and all the black leads tied together and connected directly to the negative of the source. All LEDs produced for PCs have a built in current limiting resistor, so they usually can be directly connected to anything between 3 volts and 12 volts.

If not then to ohms should be added in series. The same voltage appears at each unit.

If you hook more than one speaker up to a single channel, it will lower the impedence and will damage the amp. You can hook up multiple speakers by using a speaker .

What do guitarists need for amp rig consulting? Uses the built-in camera mic. The limited guitar-playing ability here shows the benefit of dry-guitar files per the Amptone Reamp Project , useful for amp builders, power-tube circuit designers, and preamp distortion circuit designers.

Easy Generator to Home Hook Up

Tip by E ScottD on Step 14 18 hours ago Upvote 0 A couple of things,that I can see that would help your project would be to install a ground rod on the generator or the box leading to the generator grounding the circuit. It could preclude instances of getting shocked if touching something energized a hotplate and a device already installed in the home the stove, range hood etc.. Adding a ground rod would help.

Apr 25,  · Keyboard amps are basically combo PA systems – you generally want the cleanest non-colored sound with the greatest dynamic range from a keyboard amp. The exception would be with certain Motion Sound amps.

My amp has started to howl or feedback by itself, what’s wrong? Certain brands of pre-amp tubes, especially the Chinese ones used by Boogie, wear out quickly and become very microphonic within 2 – 3 years. The elements inside the tube suffer from metal fatigue due to the changes of temperature that they undergo. When they become slack enough they start to vibrate and cause the howling sound you are hearing. Sovtek models are less prone to this as well as higher quality brands.

Back to top Q: Should I turn my amp off between sets? No, always leave the amp on standby. This will prolong the life expectancy of your power tubes. It will also prevent premature fatigue of your pre-amp tubes. Only turn it off when you are finished for the night. If there is no standby switch to your amp it is probably better to turn it off between sets if it gets very hot and the air circulation is bad.

I left my amp on not on standby overnight. What kind of damage this will do to my amp?

Routing Multiple LEDs to a Single Switch

Low RPM turn on and charge Fits factory applications Low and high current applications Multiple finishes available But now that people are driving their classic cars more often, and upgrading them to be more drivable, they are also adding more electrical components so that driving them is more enjoyable. Some cars also have an air suspension system, meaning the compressor needs to keep that air tank full — and that draws on the electrical system more than ever was intended.

Upgrades to digital ignition boxes and alarm systems also add to the amount of wiring that is added to a vehicle; people are also adding electric cooling fans to replace the mechanical fan. So how do you upgrade an electrical system that was never designed for all of these accessories? Many factory alternators from the classic car era had gauge wires, which are not sufficient to handle higher alternator outputs.

One solution to the charging dilemma is to upgrade to a single-wire alternator that puts the power directly to the battery — and only when the engine is running.

There are several ways to look at whole home audio amps and power requirements: a single product solution, or using multiple amplifiers for each zone. There are several ways to look at whole home audio amps and power requirements: a single product solution, or using multiple amplifiers for each zone. If you just wired up six or eight.

There are several ways to look at whole home audio amps and power requirements: Using a single product solution, or using multiple amplifiers for each zone. It turns out, there are several ways to power a house full of speakers. Using a Speaker Selector Switch For some, you may just want to distribute low level audio to a couple of additional rooms in your home. If you want to route an extra zone to the garage, or perhaps the kitchen, but not necessarily fill your whole home with audio, then this little box is an excellent choice for routing audio from one location to several others.

Using a speaker selector switch allows you to take the outputs of an amplifier and distribute them to as many as six or eight different speaker-pair locations. Most amplifiers are simply not equipped to power more than one speaker per channel. In short, it keeps it from blowing up and simply reduces power and output across all of the connected speakers as needed. There are also different types of products which fall into this category. First, there are simple impedance matching switches.

These split an audio signal and route the output to any of the selected speaker pairs.

Installing Multiple Amplifiers Hook up multiple amps The crossover will have built in line drivers which will increase the voltage of the low amp signal. The amp is currently mounted on the back of the rear seats. It may save you a lot of time and money. The relay will receive the low current signal from the head unit which will trigger the relay.

Wee go is the safest, easiest and most reliable portable lithium ion jump starter for cars, trucks, boats, motorcycles, ATV UTVs, and more. Wee go 66, our most powerful high-performance model, quickly and easily jump starts 10L gas and 5L diesel engines.

This would allow you to safely leave all of the batteries that aren’t in active use to charge at their own ideal rate. This is the approach that your distributor is recommending to you. It is possible, though far from ideal, to charge several 12V batteries monoblocks with 6 cells in parallel. It works much better if they are all the same age and they must be the same brand and same capacity. What you really want is for them to have the same specific gravity in each cell in each monoblock.

It sounds like you are using flooded batteries, so checking for proper electrolyte levels often will be very important. I’d recommend the following guidelines for charging multiple lead acid batteries in parallel:

How to Pick the Right Battery Charger

Using PC power supplies in things other than PCs So what’s all this rubbish about multiple 12 volt rails? If you’ve paid much attention to current power supplies then you’ve probably noticed that most of them have more than one 12 volt rail. A conventional dual rail ATX12V power supply has two 12 volt rails: EPS power supplies can have as many as four 12 volt rails and have many combinations of which rails powers which devices.

If a PSU needs more 5 volt power then they just build a higher-capacity rail which can supply more current.

May 22,  · I know this is going to sound pretty dumb but I am not sure how to go about hooking up my equipment properly. I have a pair of Carver M t amps and a Carver t preamp along with a pair of AL IV speakers.

The spreadsheet calculates required grid bias, power output and drive required for either A1 or A2 operation, and provides 3 sets of distortion curves vs power level. This allows you to find “sweet spots” by noting distortion changes as you alter the bias conditions. It’s currently set up for an A tube or a 10, which has the same characteristics , but directions are also given for easily altering the spreadsheet to accomodate other devices. Download the zipped file here.

In the past, this was done with a lot of calculations on slide rules, tables, and guesses. However, theory sufficiently detailed to allow successful design did emerge; it was just very “painful”. Now, with the help of a little Excel spreadsheet, you can play at inventing your own tube. I have included a small zipped up Excel spreadsheet that allows you to enter your own dimensions for your hypothetical tube.

The spreadsheet then gives you the approximate parameters MU, gm, rp and then provides a set of plate curves associated with that geometry. In addition to inventing your own “dream tube” you can enter dimensions of an existing tube 6SN7, B, or whatever , and get a set of nice, clean, large plate curves. If you haven’t the dimensions, who does? I was able to duplicate 6SN7 curves using several different geometries.

Marine Stereo Installation Tips

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.

You can hook up multiple transformers in parallel to increase the current, although at some point, it is cheaper to just get a bigger transformer. If you are buying new, this is certainly true: a transformer of twice the rating costs less than twice as much, and is more efficient to boot.

Just what is tone? What is a good tone and how do you achieve it? Which amps you should choose for your setup and how to get the tones you want. Check out part 1 and part 2. Amps People tend to prioritize guitars and a bunch of pedals and forget the importance of a good sounding amp. Choosing the right amp for your setup is crucial for getting the tones you want from your guitar and pedals.

I strongly suggest that you buy a guitar and amp before you spend all your savings on pedals. This will ensure the best fundament for your tones and playing. A tube amp consist of a pre-amp section that takes the small signal from your guitar and amplifies it enough to drive the power amp section. Most amps allow you to manipulate the pre-amp signal with a number of gain and EQ controls. The signal is then fed into the power amp, which gives the power to drive the speakers.

The amp could either be a head with one or more speaker cabinets or a combo, with the amp section and speaker cab combined.

How to Use A Speaker Selector for Multi-Room Audio

On most leds with leads, the longer lead is positive. Leds are current sensitive devices, meaning that if the current flow through the led isnt limited, the led will burn out. Usually this is prevented by using a resistor to limit the current thru the led.

Multiple Units Banked Together Installation “R” Series is V single-phase in and V three-phase out, 60Hz and 50Hz use. “RH” Series is V single-phase .

Using multiple transformers to get more high voltage power. Neon sign transformers Like a lot of experimenters, I started with a neon sign transformer as a high voltage source. You can also get bigger transformers, however, they are special order, and are more expensive. Furthermore, they have more current output, but the voltages stay in the same 15 kV range.

In the neon sign business, there just isn’t much call for higher voltages. Also, the standard wire that signs are wired with is rated to 15 kV, providing a nice 2: The impedance of the series inductor serves to limit the current, while not dissipating much power as a resistor would. The same technique for current limiting is used in arc welders, although at a somewhat lower voltage and a lot more current. However, we all want more voltage or current.

Let’s look at voltage first. You could just increase the primary voltage, which will raise the secondary voltage in proportion.

Working Through the Stages of Rehabilitation Pain and Phantom Limbs Phantom limb pain is the feeling of pain in an absent limb or portion of a limb. Phantom limb pain can range in type and intensity and varies from person to person. For example, a mild form might be experienced as a sharp, intermittent stabbing pain causing the limb to jerk. An example of a more severe type might be the feeling that the missing limb is being crushed. Often phantom limb pain diminishes in frequency and intensity over time.

For a small number of amputees, however, phantom limb pain can become chronic and debilitating. A great deal of research has been done to explain what phantom limb pain is and how it is caused. Techniques for alleviating phantom limb pain can be found in our Pain and Phantom Limbs booklet.
