Connecting the speakers (continued) Biwiring These speakers support biwiring, allowing you to directly connect the LF (low frequency) and HF (high frequency) for each speaker. This connection method is intended to achieve even better playback audio quality than normal connections. Use a pair of cables each for the LF (low frequency) and HF (high frequency), and connect the + terminals to the amplifier + terminal(s) and the − terminals to the amplifier − terminal(s). Connect the right (R) speaker in the same way Checking the phase If the polarities (+/−) of the left and right speakers do not match, they will be out of phase and good stereo playback sound will not be possible. To check the phase, play a mono audio recording that has strong bass frequencies through one speaker and then both speakers. If the bass frequencies sound is weaker with both speakers, they are probably out of phase. If they are in phase, low-frequency sound should be rich abundant and the stereo image should be placed in the middle between the left and right speakers. If they are out of phase, low frequencies will be missing and the stereo image will be unclear. In this case, check the polarities (+/−) of the connections between the speakers and the amplifier. By reversing the polarity for one speaker, the phase can be corrected. Speaker cables are connected to the input terminals on the backs of the speakers. The red terminal is positive (+) and the black terminal is negative (−). Check these carefully when making connections. Amplifier Remove both links oo Use speaker cables of the same length for both the high-frequency and low-frequency connections. oo Remove the links connecting the two + terminals together and the two − terminals together. 6
