This ensures the greatest possible results.Īs the name might suggest, in our DIY kits you will find everything you need to build your own amplifier. A monoblock, on the other hand, has a full power supply for one channel. This may seem inconvenient compared to a stereo amplifier. A stereo setup requires two channels, which requires the use of two monoblock amplifiers. What is the difference between a Monoblock and a Stereo Kit?Ī monoblock amplifier is a one-channel amplifier. This way, you can not only say 'I built it myself,' but also know every single component of your amplifier. You can put together your own amplifier and customize it however you want. With an amplifier kit, you get a DIY kit for an amplifier where each component is calibrated to another. SoundImpress DIY amplifier kits are equipped with the best amplifier components the market currently has to offer. In addition, we offer premium high-end DIY amplifier kits from our SoundImpress brand. Here at SoundImports, you can buy DIY amplifier kits from our premium brands Hypex and Sure Electronics. This is the amplifier with the most power. The second takes care of the 'hard work,' adding gain to the signals that will be used to feed two speakers. The first, called the preamplifier, allows you to combine and select different inputs as well as choose the required gain level. The functionality of an amplifier can be divided into two categories. Since we still have more than enough signal, a potentiometer for each amp will do what we need.An amplifier is a device that converts low-voltage signals from your source equipment into a signal of sufficient strength to drive a pair of speakers. However I suspect that the amps do not all distort at the same input so will want different levels.

In some markets, a 'transistor radio' 10k:2k transformer is readily available, and will give a small drop of level (still plenty to beat-up the guitar amps). Three 10k:10k transformers seems a happy solution. More if you recognize that a guitar amp needs MUCH less signal than a console can deliver. A console output can drive hundreds of feet of cable and up to 80 guitar amp inputs. > To split the balanced signal that will come from a console and to send it to 3 transformers you need buffers that will make the job. The Jensen JT-10KB-D is meant for that ( ).īut there are much more affordable options such as Edcor (not an endorsement - never used them) for both 1:1 and 4:1 (, ). 4:1) used in these types of applications to provide the level padding at the start. It's more common to see a stepdown transformer (e.g. At some point in your signal chain you'll need to pad that down because it would probably overload your amp or pedal 'consumer' level inputs. This would maintain the signal level of the input at the output which might be '+4dBu' 'pro' level. Thank you also for the links, I will check them. This tool is for a studio setup with long cables (balanced) and the amps will be in a separate room, that's why I need the Active Re-amp.Īs I understand, the first transformer makes the conversion balanced to unbalanced and please correct me if I am wrong, for this conversion I can use the Jensen JT-11P-1.Īfter that I will split the signal that I will send to buffers. Thank you GGBB for the nice explaination.

There's a link on that page to the 'open source' project details if you don't want to buy the kit. (not an endorsement - never used it).įor DIY balanced conversion and isolation check out (not an endorsement - never used it). You're in luck because you need three outputs, so to isolate them all you only need two channels of isolation, and those are common e.g. If you need output isolation, they are passive, and you can find them commercially for probably a lot less money than you could build them. The buffers are used to handle impedance considerations just like buffers in pedal circuits.įor a home studio setup, you might not need the output transformers - all gear could be plugged in to the same AC in the room and not have problematic ground potential differences.įor the same reason, you might not need the input transformer, and your DAW might have an unbalanced output so you don't need balanced conversion either.īut you will need buffers, and those are simple. Ground isolation avoids noise from ground loops, which can be a big problem when long cable runs connect multiple powered devices with different ground potentials. The JD7 uses one transformer for balanced conversion and isolation of the balanced re-amp signal and device, and a bunch more for phase inversion and isolation of the outputs and devices/amps. The main purpose of the transformer is not impedance matching - it's balanced to unbalanced conversion and ground isolation (although both can also be done without a transformer).
