PLIIz is being supported by offering the option for either front height or surround back channel output. Therefore, the surround back pre-amp output can also serve as the front height output. As discussed several times in the past, many PLIIz and Audyssey DSX products have been released using eight-channel DAC's, thus requiring users to select whether to set up a 7.1 system with surround back speakers or a 7.1 system with front height speakers. Outlaw is doing that by building the processor with a 7.1 pre-amp output. Others (like Marantz with the AV7005) include separate outputs for surround back and front height, but you can't use both simultaneously.
