Mark Levinson Integrated
There is also a built-in subwoofer crossover and output for those wanting to set up a 2.1-channel system to accommodate both music and movies. A feature called “Signal Doctor” can process low resolution audio sources to better match their higher-rez (or at least CD quality) brothers.
There’s also a home theater bypass input to facilitate a system configuration in which surround sources connect to an AVR or pre-pro. The latter feeds the L/R channels from its preamp outputs into the Levinson (which then amplifies the left and right speakers), and the pre-pro or AVR feeds the center and surround channels to an outboard amp (or the AVR handles the amplification for those channels). Two-channel sources connect directly to the integrated amp.
