The following instructions are for creating a MegaSquirt to Relay Board cable. It is for those who are creating their own harness. With both boxes mounted, measure the distance between them from DB connector to DB connector – this will be the length that you will cut the individual wires. If you are not using a Relay Board, allow enough length in each of your wires to reach the target component. It is often better to be too long and trim afterwards, than to be too short and have to splice additional lengths on. For a Relay Board cable, you can move both heat shrink pieces to the center of the wire length, and then twisting the center of the wire with a few twists to hold the heat shrink in place, so that it does not fall off the wire or run down while soldering the connection. For a pigtail, you can slip the heat shrink tubing on later. Orient them so that both are facing the same way, with pins 1 – 19 closest to you. You will definitely want something to hold the connector, since as you attach more wires it wants to move around more, while at the same time you have less room to solder. Having it held stable helps a lot.

Capacitors in Amps. Can they be upgraded?

You should have bought a new capacitor with the motor, if you did connect the two brown wires to the new capacitor. The other two wires go directly to the contactor. One on each hot leg after it goes through the contactor

Jun 26,  · Best Answer: Two amps, TWO capacitors, and try to keep the amount of wire between each amp and its capacitor as short as possible. An amp pulls an amount of current from the electrical system that fluctuates according to the sound that the amp is : Resolved.

Change Your Caps, Change the World! But for guitar tone controls, the type of capacitor does not. Many players know you can change the voicing of your tone pot by substituting capacitors of different values. This post is designed to fill the gap. The tone pot and capacitor comprise a low-pass filter, so, when you lower the pot, you lose treble and your tone gets darker.

Today I was working on my fave guitar, a James Trussart Steelcaster. Then I recorded quick demos for six possible cap values.

How to Build a Passive Crossover for a Speaker

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.

Wiring in one amplifier can be complicated enough, especially when you’re dealing with a factory car stereo, and the situation just gets more complex when you add multiple amplifiers to the equation. You can wire two amplifiers, or even multiple amps, in one car audio system, but it takes some extra.

Likes Received I believe Metricar is talking about a 65 amp output power plasma cutter and another amp output plasma cutter. The output power amperage will be totally different than the input power requirements. There are two prongs for the power, and one is a safety ground. It is called a 3 wire single phase. There also are single phase household outlets for things that use more power, such as an electric stove, an electric dryer. These outlets typically will have 4 wires or 4 prongs, measuring across the two main hot wires you will see volts or or , and measuring from each hot to the neutral you will see volts.

There also are 3 wire volt single phase circuits In most commercial buildings there is 3 phase power, which is much more efficient for powering industrial equipment. A 3 phase power outlet will have 3 wires for power, and if it is volts you could measure volts between any combination of the 3 wires.

We have four questions that mainly relate to power capacitors and multiple amp systems (two topics). Q1: “Is there any trick to wiring TWO amps to one capacitor” A1: .

This project will show you how to build a negative voltage generator that runs off a single rail supply! The Need for a Negative Rail Many hobbyists will have come across an op-amp circuit that uses a dual rail supply. One solution is to split the incoming power supply and create a virtual ground between two resistors in a potential divider.

However, this solution has some issues. But using an oscillator, some diodes, and a clever arrangement of capacitors, we can exploit an effect called capacitive coupling whereby a negative voltage near equal to the supply voltage can be generated For example, if both sides of a capacitor are at 0V and plate 1 is suddenly brought to 10V, the voltage on the other plate will immediately begin to rise to 10V. The same goes for the opposite: If the first plate is brought from 10V to 0V, then the other plate will attempt to drop by 10V to keep the voltage across the capacitor constant.

Notice how the negative change gave a V when the left plate was charged to 10V and the other plate kept to 0V. This is the sequence that will be exploited to generate the negative voltage. But how do we charge the left side to 10V without the other plate also charging to 10V? Remember that when you get the first plate to 10V the other side will also try to get to that voltage.

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 sending any of the above list of commands through the interface the instrument supports, the supply can be controlled with a computer rather than pushing front panel keys. This is very useful especially when doing more complex setups like generating dynamic voltage steps using list mode. Multi-range Supply Most conventional power supplies operate with fixed voltage and current ratings, e.

The benefits of this architecture are clear: A multi range supply offers greater flexibility in output ratings and allows users to substitute several fixed rating with a single multi range supply , thus saving cost and bench space. The most common and versatile regulated DC power supply is the constant current CC or constant voltage CV type which as the name implies can provide either a constant current or constant voltage within a certain range, see image below.

This permits continuous transition from constant current to constant voltage modes in response to the load change. The intersection of constant voltage and constant current modes is called the crossover point. The figure below shows the relationship between this crossover point and the load. For example, if the load is such that the power supply connected to it is operating in the constant voltage mode, a regulated output voltage is provided.

The output voltage remains constant as the load increases, up until the point where the preset current limit is reached. At that point, the output current becomes constant and the output voltage drops in proportion to further increase in load.

Features one channel and two inputs; volume, bright, treble, treble expander, bass, bass expander, bright switch, deep switch, stand-by switch, pilot light for stand-by and operate. This amp was built to play larger halls and outdoor concerts. The lack of reverb was not a big issue as most live performances had acoustics full of reverberation halls, arenas.

Peter Traynor built these things to stand up to road abuse, unlike a lot of vintage stuff. It sounds great with either bass and guitar, providing a clean and loud tone. Works great in large club settings.

Nov 14,  · Can I wire the 4amp channel up along with the jl amp on a 1 farad cap or is that a bad idea? Should I get a higher farad cap? Im also going to be ordering an aq soon.

This e-book covers the Light Emitting Diode. It has changed from a dimly-glowing indicator to one that is too-bright to look at. However it is entirely different to a “globe. A LED is more efficient, produces less heat and must be “driven” correctly to prevent it being damaged. It’s simple to use a LED – once you know how. A “Natural” or “Characteristic” voltage develops across a LED when it is correctly connected in a circuit with a current-limiting resistor to allow a current between 1mA and 20mA.

This voltage is shown in the table above and we normally use the lower value for each colour. However the table shows the voltage varies quite a lot and this depends on the actual crystalline construction of the crystal and the way it is manufactured. You cannot change this and that’s why you need to measure the voltage across the LED when building some of the circuits.

The voltage across a LED depends on the manufacturer, the intensity of the colour and the actual colour. You must test the LED s you are using. The voltage across some LEDs increases by mV 0. If you are using a 12v supply, you cannot should not put 4 white LEDs in series as the “characteristic voltage will be 3.

Line or Load Side of Motor Disconnect? Jan 25th, Question: Where do you place a capacitor line side, load side of motor disconnect, short-circuit protection device, overload for a hp motor 3-phase power factor correction capacitor? Also, why do capacitors lower the current? Steve Dodd Response No. In regard to the PF correction question, place the capacitors on the LOAD side of the motor starter, as near as possible to the motor s.

Give them overcurrent protection, also [fuses]. Also, place a “draining resistor” in parallel with them, with a value of something like 22K. This will assure that there is no stored charge left in them after the circuit is opened. The motor will drain them, but if the motor is disconnected from the circuit and the circuit is energized, this will charge the capacitors and leave them charged after the circuit is re-opened. The capacitors will offer Capacitive Reactance [Xc] to the circuit, while the typical loaded induction motor will offer Inductive Reactance [Xl] to the circuit.

An example circuit below:

Two amps, one capacitor?

Each tone wheel is a steel disc similar to a gear, with high and low spots, or teeth, on its edge see figure As the wheel rotates, these teeth pass near a permanent magnet, and the resulting variations in the magnetic field induce a voltage in a coil wound on the magnet. This small voltage, when suitably filtered, produces one note of the musical scale, its pitch or frequency depending on the number of teeth passing the magnet each second. Unlike those organs which produce complex tones and then use filtering to achieve the sounds of traditional instruments subtractive synthesis , the Hammond organ produces nearly pure sine wave tones and then combines these to create instrument sounds additive synthesis.

Tone Filtering For this scheme to work, those pure tones must be as close as possible to pure sine waves. This was achieved by manufacturing the tonewheels with appropriately shaped teeth and then using electronic filtering to remove any harmonics generated by inaccuracies.

Disagree. Place the cap in parallel with the subs amp, directly before it, but grounds are separate as talked about above. The distro should be placed before the cap, and its job is to separate sub wire and mains wire. Use as heavy gauge as distro output will allow to the cap/amp, and it really should be the same gauge as the main power wire.

I love my powered mixer and don’t really want to replace it and most of the time it provides all the channels I need. But occasionally, I might run out of channels. I have a Y connector XLR cable that will allow me to plug two microphones into a single input, but then the volume and EQ cannot be adjusted independently. I have a Mackie S powered mixer Mackie S running passive speakers with a non powered monitor output to which I connect a series of powered monitors as floor wedges.

It has 8 channels with an XLR input and a line input on each channel. I am wondering if I can use a non powered mixer such as the Behringer Xenyx Small Format Mixer or any similar mixer as a sub-mixer by connecting it to my powered mixer. I am just using this mixer as an example and not asking for opinions on the quality of that particular mixer. Then I am thinking I can plug additional microphones, guitars, pianos, electronic drums, etc. Are there potential pitfalls?

Will it cause any problems? And if it is feasible, should I use an instrument cable or speaker cable to connect the two mixers together? Could I send the main signal out through the “tape out” RCA jacks of the sub mixer into the tape input RCA of the powered mixer and send the monitor output from the sub mixer into channel 7 or 8 on the main mixer to preserve the ability to control the monitor feed from the sub mixer?

Each speaker is designed to operate and reproduce a certain frequency range of sound. Speakers designed to handle high frequencies are called tweeters. The middle frequencies, including voice frequencies, are handled by mid-range speakers. The low frequencies are handled by woofers and subwoofers. Crossover networks are used to direct a certain frequency range to the speaker that can best reproduce it. Use a crossover design program or a crossover design table to determine what values the inductors and capacitors will need to be to get the crossover points needed.
