Marantz SR7500 Dolby Digital Home Theater Receiver

"When you look at the SR7500s list of user benefits, two things stand out immediately: THX Select certification and M.R.A.C., or Marantz Room Acoustic Calibration. Why are these important to you? Well, THX Select certification isnt just another logo on the front panel. No, it means that THX, the people who are responsible for the way home theater systems should sound, have turned a hyper-critical and ultimately favorable eye on the SR7500.

With 105 watts RMS per channel, you (or, more accurately, your receiver) will be in almost total control. And for that last bit of sonic assurance, youll be able to count on M.R.A.C.! Why? Simply stated, Marantz Room Acoustic Calibration deals with the variables inherent in any home theater system: the speakers you choose and where you place them. During initial set-up, M.R.A.C. analyzes your room with microprocessor accuracy and adjusts internal circuitry to compensate for the unwanted changes every room introduces into the audio signal you hear. On the video side, the SR7500 shows its pedigree with circuitry that will su
