I have 4 great speakers and a very nice Amp. It's like this,... the amp doesn't have surround option on it so I want to connect it so it is 'Semi Quadrophonic'... If i'm correct, it's almost the same as Surround only your using 2 ouputs. Does anyone know how to do that ? Or does anyone know a better solution ? Thanks alot, Romain |

As the article states, "Use extreme caution when first attempting this as some amplifiers cannot handle the bridging of their negative speaker terminals." http://kantack.com/surround/surround2.html http://www.sa-cd.net/showthread/18552/40473 http://members.tripod.com/martin_leese/Audio/HaflerCircuit.txt http://sound.westhost.com/project18.htm . |

Studio stuff sometimes lacks the 'cues' that make live recordings best. And you really DO need to be careful. In general, the Negative /Ground terminal for each channel should be at the same potential....the ground of the amplifier, for this to work. Get a Technician to check this out before just hooking stuff up. With the correct recordings, this works well. Balance speaker sensitivities or 'pad' the rears if they are too loud. I did this circuit with 2 amplifiers. The 'front' was hooked up normally. The rear had the speakers connected positive to positive witha 10 ohm / 10 watt power resistor in place of the normal speaker hookup. The amps were connected using a line level RCA cable and front to back balance was achieved using the volume control on the back amp. Experiment with rear speaker placement. Using them as left/ right (rear) may work, but I also tried back-to-back wired in or out of phase to give me a dipole or bipole effect. |
