The cheap transformer is used solely as an inductor. Multiple re amp boxes No, one per amp is all And not even that if you. ![]() Reamp box takes line level low imp and changes it to inst level high impedance. It provides neither isolation nor unbalancing. Easy DIY job to make and you dont need a particularly wonderful 1:1 transformer. Guitar/bass amps are made for hi imp, lower instrument level. Here is a third one : not exactly intended for reamping, but similarily designed to looks like a guitar to the next circuit. Guitar volume pots are usually in the 100k+ range. Its meant to emulate the output z of a passive pickup + tone and volume pots. The 1M series resistor looks overkill to me, it looses again 3dB combined with the input impedance of the amp. yes no, it shouldnt not go to ground theres no backwards with a 1:1 transformer Just a bit of unsolicited feedback, that impedance pot is too small value to do anything. One could mix both designs, for example adding the 10k series pot for "impedance" control instead of a fixed resistor. The ground is permanently lifted (no connection on pin 1 of the XLR socket). 1/4 TRS line inputs, Transformer-balanced XLR output (microphone level). The Recording Mag thing uses a cheaper transformer for unbalancing, and a separate inductor for pickup simulation. DI Box Re-amping interface for multiple sources, Stereo / Dual Direct Box. ![]() ![]() Your main (buffered) output goes to one amp and the isolated output goes to the other. If you use 2 amps all you need to do is stick the HumDinger at the end of your effects chain. Using the HumDinger to get rid of earth loops is easy. The Jensen design uses an expensive transformer for both unbalancing and inductive loading. The best and safest way to get rid of an earth loop is to isolate the ground that is causing the hum. I gess it's good for balanced +6dBu professional line-out level, not for unbalanced -10dBu semi-pro line-out. All prices challenged, call for your best price on the Radial ProRMP Passive Reamp Box with. It's a kind of anti-preamp : basically, you want some attenuation (from line level to typical guitar level) and an inductive impedance to simulate the loading of the guitar pickups.īoth designs you're linking at also take care of isolating and un-balancing the signal, but you might not need that depending on your recording gear.
