Bi-Amping Connections
The optimal method of powering the
amplifiers, one for low frequencies and one for the mid/high frequencies.
It is necessary to use a high-quality active crossover module. Since each
amplifier only drives a limited frequency range, this method allows the
user to select amplifiers with the desired sonic character for low and
high frequencies.
Make sure that the input sensitivity of each of the amplifiers is the same,
or that input level controls are provided to maintain the proper low-to-
mid/high balance. If two identical stereo amplifiers are used, one may be
located near each loudspeaker to drive low- and mid/high-frequency
sections through short wire runs.
The external "strapping bars" that normally connect the
low-frequency and high-frequency terminals must be removed before
bi-amping.
To remove the shorting straps, simply loosen and slide the bars off to the
side (Figure 8).
If the system is wired in the bi-amp method, set the Bi-Amp/Normal
switch to the Bi-Amp position (Figure 9 and Figure 9a).
