Description
Hola! Recientemente compramos una potencia en la iglesia a la que asisto, y en una seccion de las conecciones colocamos una caja de inyeccion pasiva. Cuando dimos marcha al sonido notamos que no teniamos señal en los parlantes, RESULTA QUE LAS CAJAS DI PASIVAS TIENEN UN EFECTO NEGATIVO MUY GRAVE: Para convertir una señal no balanceada a una balanceada (hot, cold, ground) toman la señal de entrada y emiten una de mucha menor intensidad (**f=220Hz@3Vin** / **f=220Hz@0.6Vout** una perdida del 80% de intensidad!!). Asique nos es necesario colocar una DI Activa, que permita emitir una señal balanceada con la misma intencidad (y calidad) de entrada. Si les interesa una version con control de volumen/ganancia speaker in y phantom power compatible, dejen su comentario. Hello! Recently, our church bought a power amplifier, and to send a sound signal we use a pasive direct inject box, so, when we turn the sound on we notice that there´s no signal in the power unit. Making some testing in the conections we notice that DI BOX HAVE A HUGE PROBLEM: they consume a lot of energy to convert the unbalance signal to a balance signal (hot, cold, ground) and that energy comes from the input signal, so at the output the voltage is very low. So we where force to conect an **active** DI BOX. They are very expensive here on Argentina, so i am currently making one. This version is not my, is the merge of lot of other desing and i chose to use or not some functions. Feel free to use it, and if you see any problem or improbement to make, tell me :). Also, if want a version for speaker in, phantom power compatible and gain/volume control, just leave a coment.
