PREAMPLIFIER OUTPUT
The preamplifier outputs may be used in many ways. Most common will be to provide signal
to an active subwoofer.
You may also use the Avatar Super as the main unit in an elaborate active biamplification
configuration. In such cases, hookup is made as follows:
1) Connect the preamplifier outputs to the active crossover inputs.
2) Connect the high frequency outputs from the crossover to Avatar Super’s Home
Theater/Cine inputs.
3) Connect the low frequency outputs from the crossover to the bass amplifier(s).
4) Set the Avatar Super to the “Home Theater” mode via the front panel control.
5) The Selector, Tape Monitor switch, volume control, and mute switch will function
as normal, controlling signal for both high & low frequency systems.
6) Adjust the relative level between the high and low frequency systems with the trim
controls on the crossover.
NOTE: The line stage of Avatar Super inverts absolute phase, while its power
amplifier section does not. Thus, overall, Avatar Super inverts phase from all
inputs to both the preamplifier outputs and the speaker terminals.
Absolute phase inversion through the Avatar Super may be corrected by
inverting your loudspeaker connections, i.e., connect the positive speaker lead
to the “G” terminal, and the negative speaker lead to “2”, “4”, or “8”.
You must take care that your bass amplifier and bass speaker are connected
to yield the same absolute phase result.
Some people appear able to hear absolute phase inversion, while many do
not. However, the phase of the recordings we buy is indeterminate, such
that any installation will be incorrect in this regard about 50% of the time.
