Hi, I have an Arcam AVR200 receiver, two Acoustic Energy AE1 mk 1's as main these operate from 35Hz-35Khz according to the manual, two Monitor Audio Radius 90 surround, 1 radius 180 center and have just added a radius 360 sub. Couple of questions. 1) The amp has one only phono out for the sub, but the sub has a left and right phono in, should the phono be split to feed both inputs on the sub? if not I assume it will make no difference if the lead is in the left or right channel? 2) Given the speakers I have, what setting should I have the sub's frequency control set to? 3) What's this about phase control? 4) should I have my main speakers set to large or small? I tend to leave them set to large as I use thse for stereo replay of music. 5) Why the hell can't I set up the amp to remember the speaker settings depending on source? I now realise I can't count and that's five questions, hope you will forgive me?
