Connecting Your Equipment Speaker impedance You can change the speaker impedance for VSX-55TXi but we recommend using speakers with an impedance of 8 Ω -16 Ω (the default setting). If you are using 6 Ω - less than 8 Ω impedance speakers, you need to change the impedance setting. Use any speaker rated between 6 Ω -16 Ω . First put the receiver in STANDBY mode, then press the power button while holding down the SPEAKERS button. The receiver will reset to the new impedance setting. With this method you can choose the 8 Ω - 16 Ω setting or the 6 Ω - 8 Ω setting. (This display indicates an 8Ω - 16Ω impedance setting.) (This display indicates a 6Ω less than 8Ω impedance setting.) Bi-wiring your speakers This high quality but difficult method of wiring speakers will be unnecessary for most users. In order to do this your speakers must be bi-wireable (that is they must have separate terminals for the high and low frequencies). To bi-wire a speaker, connect two sets of speaker cords to each speaker terminal on the receiver. The easiest way to do this is to connect one wire in the normal way, and use a banana plug for the other one. Make sure you use a parallel (not series) connection when doing so. Don't connect different speakers from the same terminal in this way. 26
