There are two ways bi-amplification is typically accomplished. One is when both pairs of
amplifier channels receive full range signals. The advanced a/d/s/ multi-channel amplifiers have
facilities to tie the inputs together, making it easy to deliver signals simultaneously to multiple
channels. With other amplifiers a set of “Y” cords may have to be used.
The other, more common way to bi-amplify the 336PX is to use electronic crossovers. The
crossovers are inserted between the signal source and the amplifiers. The advanced a/d/s/
multi-channel amplifiers have built in crossovers which may be used also. While this is
normally the preferred method of bi-amplifying most systems, the quality and precision of the
336PX crossover favors the use of it’s supplied crossover, not an external active one. Because
of the complex and precise crossover contours required by the 336PX, it is unlikely that an
electronic crossover will provide superior results.
