This Onkyo ES-600PRO AV Surround Processor is for interconnecting with your existing two-
channel stereo system, and provides an additional center channel as well as rear channels in
order to achieve surround sound. This unit actively decodes a two-channel stereo system to
produce sound that is remarkably similar to what you’d hear in a movie theater. You can
independently control the center channel as well as rear channels. The center channel is not
just a combination of the left and right signals -- the ES-600PRO uses logic steering circuitry to
increase separation for pinpoint directionality, image stability, and enhanced overall sound
quality. With four surround modes, namely Dolby Pro Logic, Dolby 3 Stereo, Hall Surround, and
Stadium modes, this unit allows you to choose the mode that best matches the program
material. You can also adjust the time delay for the rear speakers to tailor the perceived room
size to the program material; the longer the delay, the larger the apparent acoustical size of the
listening room. The robust ES-600PRO has three built-in high-power amplifiers to complement
your existing two-channel system: Center 50 Watts, Rear 2 x 20 Watts. The unit includes
connections for a two-channel stereo amplifier/receiver, graphic equalizer, center speaker, and
two rear speakers. Instructions are included. Made in Japan. Tested and functions properly.
