Amplifier to Loudspeaker Connection
1) Conventional Hook-up
Connect speaker wire from the positive (Red +) terminal on your amplifier to
positive (Red +) terminal on your Mirage speaker. Connect negative (Black –)
terminal on your amplifier to negative (Black –) terminal on your Mirage speaker. (see
figure 2)
2) Bi-Wire Hook-up
Remove shorting straps. Use two dual conductor cables; one cable for low
frequencies and one cable for high frequencies. Separate connections are made
between the power amplifier to the low frequencies binding posts on the speaker
and from the power amplifier to the high frequency binding posts.This allows you
to choose separate wires that are best suited for the low or high frequencies.
(see figure 3)
3) Combination Bi-Amp/Bi-Wire Hook up
This method uses separate amplifiers for the low frequency section and high
frequency section of the speaker.This dramatically improves musicality.The amplifier’s
gains and the phase relationship of the amplifier’s input to output
must be identical. (see figure 4)
