Chu Moy headphone amplifier

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.

Technical Details

I have a much better understanding of ohm cooking. I have two combo amps. One is a Fender Superchamp X2. The one speaker out jack that the internal speaker is connected to says Minimum 8 ohms.

Nov 23,  · Two amps should be connected to two speakers. You can divide the input signal into both amps. Many guys plug their axe into one amp input then plug another guitar cable into the second input and the other end into the imput of the second amp.

Connecting solar panels together can seem like a daunting task when you first start to look at how it should be done, but connecting multiple solar panels together is not that hard with a little thought. Wiring solar panels together in either parallel or series combinations to make larger arrays is an often overlooked, yet completely essential part of any well designed solar power system.

There are three basic but very different ways of connecting solar panels together and each connection method is designed for a specific purpose. For example, to produce more output voltage or to produce more current. Solar panels can be wired in a series or parallel combination to increase the voltage or amperage respectively, or they can be wired together in both series and parallel to increase both the voltage and current output producing a higher wattage array.

Whether you are connecting two solar panels more more, as long as you understand the basic principles of how connecting multiple solar panels together increases power and how each of these wiring methods works, you can easily decide on how to wire your own panels together. After all connecting solar panels together correctly can greatly improve the efficiency of your solar system. Connecting solar panels together in series is used to increase the total system voltage.

Oddball Amps: Univox, Silvertone Amp, Harmony, Danelectro, Magnatone & More

You may compare these with your own speakers to determine what you have. Speakers are like ice cream; we all have our favorite taste. Some like strawberry while others like chocolate.

So from what most of you say you can’t hook up 2 amps to each other but i have two power acoustik watt mono amps that need to be hooked up to 4 10 inch watt subs, is it better to run them together as “one” or seperate bridged at 4 ohms.

Electric fluid “Charge-stuff” Why are Amperes confusing? Suppose that we had no name for “water,” and yet our teachers wanted us to learn all about the mysterious flow inside metal plumbing pipes? Suppose we were required to understand “gallons-per-second,” but we had to do this without knowing anything about water, or about gallons? If we’d never learned the word “gallon”, and if we had no idea that water even existed, how could we hope to understand “flow?

We might even decide that “current” was an abstract concept. Or we might decide that invisible wetness was moving along through the pipes. Or, we could just give up on trying to understand plumbing at all. Instead we could concentrate on the math, memorize equations. Do extremely well on any physics test, but we wouldn’t end up with any gut-level understanding. That’s the problem with electricity and amperes. We only can understand the electrical flow in wires the amperes if we first understand the stuff that flows inside wires.

What flows through wires? It’s the charge, it’s the metal’s own particle-sea, the Coulombs CHARGE “Charge” is the stuff inside wires, but usually nobody tells us that all metals are always jam-packed full of movable charge.


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.

How To Strap Two Amps Together, Double Your Power! For this how-to, I’m going to use the DC Audio k. For the most part, “Strapping” – aka ‘Bridging’ – TWO amps together is done to get Double the @1ohm Power Rating of One Amp.

Our 50 watt light bulb is drawing. In the above watts, volts, amps calculations, these simplified formulas are for DC voltage. In an AC circuit, things are more complicated. An electrical load in an AC circuit will typically use both real power – P – and reactive power – Q – definitions below. Since power factor varies all over the place, We include additional more technical explanation of power factor, real power, apparent power, complex power, and reactive power just below.

Various sources offer further definitions of real power P, reactive power Q, complex power S, and apparent power S.

How to Hook Up Heads and Cabinets

Most receivers have either preamp-in and preamp-out connections or tape monitor connections. In most cases, these are the best way to connect an equalizer to your stereo. Connecting to the tape monitor channels will require connection to only your receiver. Learn how to hook up an equalizer to the receiver instead. To run a signal from your stereo receiver to the equalizer and then to your amplifier, you will need 2 sets of RCA cable the same kind that is usually used to connect source components like turntables and CD players.

Connecting two guitar amps together is a technique that many veteran guitar players use to expand their sound. This technique allows you the ability to use two different-sounding amplifiers to create a .

Here is what I recommend. This measure assumes a reasonable ambient air temperature typically c , that the heat sinks are black anodized, have free air circulation not using a fan and given plenty of breathing room-usually 8 inches on all sides and don’t sit directly on the floor , and that the fins of the heat sink are oriented vertically. Be aware, though, that different vendors will have different assumptions when measuring and quoting the thermal dissipation of their heat sinks – sometimes you cannot reliably trust the figures.

To get an idea of what you need, follow these steps: Divide 25c max thermal rise that you want by the quiescent power consumption of your amp per channel for building monoblocks or for 2 channels together if building a stereo chassis, keep in mind this is the wattage dissipation, NOT output wattage – they are very different specifications.

This de-rating takes into account all of the inefficiencies of mounting your output transistors to the heat sink and the less than favorable conditions that you are likely to create in building your amp even if you follow the advice above trust me, no matter what you do, it won’t be ideal. Take this number and round it down to the nearest th decimal place. This is the size of a heat sink that you really need. Then think of a way to get more


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. We also looked at the importance of choosing the right guitar — not only for your technique and rig but also for inspiration to play and create music.

May 09,  · Hello all, Up until the weekend I owned two amps, a Cornford Hellcat and a WEM Westminster, both hardwired valve amps. I found myself in the guitar shop over the weekend and remembered reading the Jazz guitar Amps section here when I saw some Roland cube amps.

Remember NEVER to heat your animals water with a direct high voltage Volt plug-in heaters as this practice regularly kills an estimated 17, animals annually once the high voltage heater gets a crack in the electrical insulation material! Only use Low Voltage heaters like ours that run on battery power or operate from a low voltage power transformer like a battery charger!! Heat your water safely this winter!

Remember NEVER to heat your animals water with a high voltage Volt heaters as this practice regularly kills an estimated 17, animals annually once the high voltage heater gets a crack in the electrical insulation material! Heat your water safely! Do not buy the VAC killer heaters!! Sooner or later they always fail! Place the heater nearest to the side used most for drinking as warmwater rises just above the heater and this spot will be a MOST ice free.

Overheat and Freeze thermostats available. Official 90 day warranty But if connections are protected they should last 15 to 30 years Outdoor connections should be covered with grease to prevent corrosion Questions And Answers Q. Also how do I get maximum battery life in winter the months. A – It works on most of the rubber maid tanks but you will have to check if it is a 1″ pipe thread.

USB Bike Generator

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.

However, there is no guarantee the either amp will sound the same as it does on its own, because the input impedance of both of them coupled together (directly or though the transformer in the DI box) will be different, which may or may not affect the tone, depending on the guitar and the amps.

I spend a lot of time wearing headphones. A computer is my principal source of musical entertainment, and my Sennheiser HD s are my preferred output transducers. It’s been a while since my main computer was even connected to a speaker system. Headphones need about a thousandth as much power as loudspeakers to achieve similar sound pressure levels at the eardrums.

This generally means a few milliwatts per side, at most, for normal listening. A few tens of milliwatts, for loud music or if you’re using unusually inefficient ‘phones – as with loudspeakers, manufacturers of high-end headphones may sacrifice efficiency for higher fidelity. You wouldn’t think even cheap music hardware would have much trouble delivering this little power. But, actually, even quite expensive home stereo gear frequently doesn’t drive headphones very well, especially at high volume.

And if you’re pumping your tunes out of a mobile multi-faceted transformative device at sufficient volume to cut through the sound of the bus, surf or very upset policeman tied to a chair , you’re likely to be asking for rather more power, from an amp of rather lower capability. Because market research has determined that most consumers are cloth-eared gits non-critical listeners, manufacturers of audio hardware in general and portable players in particular often don’t care much whether their products drive headphones very well.

Lots of cheap portables also come with ghastly bundled earphones that add their own vacuum-cleaner-tube ambience to everything.


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.

Jan 08,  · Need to wire multiple amplifiers? Here is a very comprehensive demonstration of how it is done by daisy chaining them and or using Y splitters.

The wires that connect it all together The Motor The motor we talked about previously. The second concern is that it will work with the voltage of the components you choose. The general rule, is that the higher the voltage, the fewer amps need to be pushed through the system to attain the same wattage. Although rated at 36V, we run our motor at 48V so we can utilize available golf cart components for the rest of our systems, which are also inexpensive and abundantly available.

For our boat, we designed the system to handle amps. If you were paying attention earlier, you might notice that our motor is rated for only 4. That is a continuous rating however.

Build the Electronics There are three major parts to the electronics of the USB Bike Generator, the stepper motor, the rectifier and the voltage regulator. In general any electric motor can be used as a generator but not all motors are well suited as generators. The stepper motor I used in my last two instructables came from an old printer and was rated at 24 volts. Through testing I found that this motor provided up to 48 volts when unloaded and spun at rpm.

Nov 07,  · Best Answer: Assuming both amps are identical and both subs are identical, just connect one to each amp. The amps can’t be connected together unless they are ‘strappable’. There are very few strappable amps on the market today. The RCA wires need to go to each amp by use of a ‘y’ : Resolved.

Summary Do not assume you can put two rated cables together to extend your length. Length and wire size are tied together to give you minimal line loss. Two smaller wire sizes although rated at a specific amperage will not be big enough and you can see significant voltage loss. You do have the option to build your own cables. The important aspect is to use rated connectors and then match a length of wire that has appropriate wire size to minimize voltage losses. The following information provides you with general information and links to specific cables that will provide you with what you need to get your appliances and tools connected.
