32. upport Single wiring Single wiring is the conventional wiring method of running a single cable per channel between the amplifier and the speaker This is the easiest technique Bi wiring Bi wiring is running two separate cables between the amplifier and each speaker with one cable carrying the low frequency information the other the higher frequency signals The P35 and P1 are designed to allow easy bi wiring but speakers support it only if separate connection terminals are provided for the two cables the speaker will have two pairs of terminals on the back one pair labelled HF or High Frequency the other pair labelled LF or Low Frequency Why is this useful Bi wiring improves the sound of your system because the separation of high and low frequency signal currents into separate speaker cables avoids distortions caused by the different currents interacting with one another within a single cable as occurs in single wired systems Bi amping Bi amping is the separation of the amplification of low and high frequency signals over two amplifiers You will require two amplifiers to do this Why is this useful The performance of your system is enhanced over bi wiring by extending the signal separation principle to use separate amplification for the low and high frequency drivers in each speaker Single wiring Both the P35 and the P1 are designed for bi wiring which ART CS is why there are duplicate speaker ter
