Hi, I am an owner of Marantz SR7300 since December of last year. I am very much satisfied with it's sound both in HT and HiFi. However, when I watched LOTR (2 towers) DVD, my unit went into 'Protect Mode' at least 5 times during the whole movie. When it goes into protect mode, sound will be cut off for about 5 seconds. I do not understand why this happened when my volume is only set to -17db. This happens when there is a sudden burst of sound. Although the sound is not very loud, it seems the sound has much bass. I feel this Protect mode is unacceptable in this volume level. After a few trials trying to simulate, ff I found out. Note: am always simulating the exact scenes where it 1st went into protect mode 1. After pressing reset buttons (back to factory settings) I can play it at around -10db but any thing lower will go into protect mode 2. I set my speaker to small, I can play at -5dB volume 3. Switched off the unit (power cord not plug) for 5 hrs, I can play the unit at +7dB (did not try higher as volume is already loud) 4. Allow unit on standby for 3 hours, I can again play it only at -10dB. It seems the longer it is on, the lower volume I can play. I have brought the unit at Singapore Marantz dealer and they found no problem with my unit. Technician and Salesman told me that my speakers could be the culprit as the power sent by the receiver is high which my speakers cannot cope and to protect my speakers from damage, the receiver goes into protect mode. I tried other movies and the same happens to some while others are ok. music cds (using analog), the protect mode only kicks in when the volume is too loud, about +10dB volume. I cannot accept that this unit will go into protect mode at such a low volume but what can I do? Can anyone who has the same receiver (and speakers if possible) to try if the same will happen? I feel very helpless and am starting to think that my purchase is not good. Oh, my speakers are all bookshelf Mains: Kef Q1 (91dB sensitivity and 8ohm impedance) Center: Kef Q9c (91dB and 8ohm) Surround: Kef Cresta2 (90dB and 8ohm) Any help and suggestion will be appreciated.
