Bi-Amping and Tri amping
Connecting each loudspeaker drive element to separate amplification offers the highest possible performance
level. It is not necessary for the amplifiers in the treble and bass sections to be identical. In fact for tube
amplifier enthusiasts, there are advantages to using smaller amplifiers in the treble and midrange sections as
the smaller transformers offer the significant possibility of extended, sweeter treble response.
To multi-amp the following criteria are essential:
!The amplifiers should be phase coherent. In other words all amplifiers should be by design phase non-inverting
or phase inverting or if not, should be connected so as to be all phase non-inverting or phase inverting.
!The amplifiers must have identical voltage gains, or should be set up so as to have identical voltage gains.
!The amplifiers must have low residual noise characteristics especially in the midrange and treble sections.
!Amplifiers in corresponding channels must be identical, i.e both bass amplifiers must be the same and so on.
If any of the above conditions are not met, separate amplification will be significantly worse than ordinary bi or
tri wiring. If you are unsure about these concepts or unsure if your amplifiers meet these criteria, it is essential
that you consult your Klipsch specialist dealer before proceeding further.
Important Note. After connecting and placing the loudspeaker upright the connections will be hidden from
view. We strongly recommend that you identify each cable to eliminate possible difficulties down the line.
