Each will have a certain amount of idle current draw when there is no audio signal present, and there will be small variation depending on circuit values. Observe the middle bolt isolation we discussed previously for each.Īmplifiers of course draw more current as power is drawn from them, so unless you have all at equal volume, and exactly the same layout ( requiring a well planned pcb for all wiring ) they are unlikely to provide equal current draw. which suits the wiring from each transformer primary to the fused IEC inlet for each. When wired in parallel Red White will be Secondary Active at 30V, and Black Orange will be termed 0VĪre you using 3 transformers ? if so you would use a chassis with 3 fused IEC inlets. Yes will be 10A of current available when wired in parallel. If I use wire terminal - 3 (L+N+G) In and 9 (3 sets of L+N+G) Out - to power 3 power amp module, does it mean that current will be split into 3 so each will get 30V AC with 3.3A each? Have I understood correctly if it is connected in parallel, it will be 1 x 30v AC with double the current and Red + White together will be AC 1 and Black + Orange together will be AC 2?
