    Portable Distribution Amplifie


    Distribution Amplifier:

    In electronics, a distribution amplifier or simply distribution amp, is a device that accepts a single input signal and provides this same signal to multiple isolated outputs.

    These devices are important because they allow a signal to be distributed to multiple destinations without ground loops or signal degradation. They are used for a number of common engineering tasks, including multiple amplification, cable television, splitting monitor and front of house mixes, and "tapping" a signal prior to sending it through effects units to preserve a "dry" signal for later experimentation.

    How to Build a Homemade Four-Output Distribution Amplifier?

    Amplifiers with multiple outputs make it possible to route a single audio signal to multiple sources. A common application of the multiple output configuration is the headphone splitter amplifier. In environments where sound must be isolated, such as radio studios, the only way to provide audio is via a headphone mix. Multiple output amplifiers function like typical amplifiers, but the difference is that the output signal is split. If you're in a band, using a four-output amplifier is a convenient way to monitor your performances without using a loud PA system.

    • Purchase the required parts either individually or as part of a kit. The advantage of kits is that all of the parts are made-to-measure and compatible and include wiring schematic, which illustrates the layout and connection of the circuit.
    • Assemble the circuit board. The blank turret board forms the base of the circuit board. Typical board-mounted components include capacitors, resistors, diodes, fuses, op-amp chip and voltage regulators. Slot these into the turrets on the board. Push them fully in so that the connector pins poke through to the base of the board. Once fully populated, place the board face-down.
    • Solder the connector pins to the metal traces on the board base. Each turret is surrounded by a metal trace. This strip connects each board-mount part. Dip the soldering iron tip into the solder. Press the tip of the soldering iron simultaneously over the connector legs and base to fuse them.
    • Prepare the chassis enclosure. If the chassis is not pre-drilled, make holes for the inputs, outputs and power supply socket. Use a standard electric drill and ¼-inch standard drill bit to cut five holes for the jacks: One on the right-hand side and four on the left. Use a dremel to cut a square hole on the back of the chassis enclosure in which to mount the IEC power supply socket.
    • Mount the jacks on the chassis. Slot each ¼ inch jack into a hole on the chassis.
    • Cut five pieces of power wire. Strip the ends of each piece to expose the metal. Solder a piece of power to each potentiometer output terminal. Solder the input jack wire to the op-amp chip on the circuit board. Solder the four output jack wires to the point on the circuit board directly after the final resistor.
    • Wire the IEC power supply or battery snap. Cut a piece of power wire and a piece of ground wire. Strip each piece of wire at both ends to expose the metal. Solder both wires to the IEC power supply, power wire to the positive terminal, ground wire to the negative. Connect the wires to the positive and negative eyelets on the board respectively.
    • Mount the completed circuit board into the base of the chassis enclosure. Screw it in.
    • Screw down the chassis lid with a Phillips screwdriver.

Works great!

I needed this device to use as an audio splitter. I don't need the video part but i assume it works. The audio output signal is clean and if you need to split one audio signal into 4, this is the way to go. The quality on this unit is good, and the unit itself is very compact so it can be stashed out of sight easily. Once you hook this thing up, you're pretty much never going to touch it again in most applications. It comes with a "wall wart" style power adapter that I leave plugged in all the time and it never gets hot.

Works Perfectly! Clean distribution and no loss.

We have TV's in multiple rooms and when on U-Verse channels, you can get different lags even when on the same channel. It was quite annoying when the gap was over a second. I switched to this and with a couple of 50 foot AV cables, I now have synced signals in 3 rooms PLUS I used the 4th to go to my Slingbox! <br/> <br/>Now if they could just make multi-room remotes this easy... I use an old RCA system that isn't available any more....

Great Product!

I bought this amplifier so I could record video from my Xbox onto my laptop, while actually playing the game on my standard TV. And it does exactly what you would expect it to. The signal quality really is 1:1, as far as I can tell anyway. If there is any degradation in the video, it's minor. The audio is excellent too. I've only tested it using two of the outputs simultaneously, but I've seen nothing to make me believe the quality of using all four would be any different. If your looking for a good composite video amplifier, then look no further.

Video Distribution Amplifier.
00:00:00 03-18-2011
I got this to add functionality to my Dish satellite receiver. The receiver has only 2 outputs--a composite output and a coaxial output. The coaxial one output non-stereo sound quality so I hated using it to hook up to my new Aquos huge flat screen tv. I needed the composite to output to my DVD recorder (Toshiba; upconverts the picture to near HD pretty well). And I am far too lazy to swap the cable out between TV and DVD recorder all the time. Oh, and I'm also unwilling to turn on my DVD recorder every time I watch TV just so I can have stereo sound. So apparently it is true I can solve all my consumer problems via Amazon as I found this product which splits my one composite.

Fantastic
00:00:00 03-08-2011
Not a lot to be said, it works perfectly, it runs cool, (I don't think I've ever felt any heat at all coming from the unit actually) and it provides an affordable way to get 1:1 reproduction. This is basically the same quality as a high cost model for display rooms, but with less inputs and outputs, meant for consumer use. It was meant to be on and working for long periods of time I gather, because there's no power switch. The way you turn it off, is to unplug the power cord from the unit, or the wall. Using it is very simple, you plug the source into the input row, and plug a male/male composite cable into each/any of the outputs, and then into the respective devices. Of course, make sure you get a few high quality shielded M/M composite cables with this unit, or it'll be useless until you do. <br/> <br/>I would highly recommend this unit for doing Let's Plays, so you can be playing the game like you normally would on the TV while recording everything you're doing on a video capture card. To be paired with this, I recommend the StarTech SVID2USB2 USB 2.0 capture card. It's a fantastic addition to this product when recording an LP, and provides one of the best setups you can put together, video-wise, for under $100.

Portable Distribution Amplifier.
00:00:00 03-05-2011
This distribution amp works perfectly although I have only used the audio portion. I was able to add my surround sound system and my wireless headphones using this product without loss of audio signal as happens with "Y" splitters.

Audio Distribution Amplifier.
00:00:00 02-28-2011
With the changeover to digital broadcast signals, I lost over the air TV reception and ended up getting satellite. I didn't want to invest in a bunch of satellite boxes to put on every TV in the house, especially when only 1 or 2 would be going at a time. The alternate was the X10 which catches the signal from one source and sends to a receiver connected to a TV. The satellite box only has one set of a/v output so this handy device allowed me to send the signal to both the TV and X10 transmitter at the same time. The setup works great. There is no signal quality loss by sending it through this device. I've also hooked up a DVD recorder without problem. I realize this box may have been overkill for what I needed, but I'm have no regrets. Great product.
