I recently upgraded my Home Theater, (New TV, 5.1 Speakers, HD DVR & BD player)
Room size approx. 400 sq. Feet with high (12-17 foot) vaulted ceiling. Prior to this upgrade I used the same AVR & had 2.1 sound. (I demoted my L&R speakers to Surround status with the upgrade)
My Pioneer VSX-D912 AVR has shut down & displayed “OVERLOAD” during very loud BD movie action scenes (Incredible Hulk, Dark Knight)
I have the volume set at -15 for movies. To stop this I had to set it at -17 for Dark Knight & drop it to -19 for Incredible Hulk. I do like to listen to movies at very loud volumes. I wonder if the lossless audio (DTS HD MA or Dolby True HD) on these BD movies are just “too much” for my AVR to handle driving 5.1 at loud volumes?
It is NOT overheating. I tested by playing just the loudest, action scenes when the AVR had been off & was COLD. It shut down anyway. I also added a small cooling fan to suck hot air out of the vents & no help (but, it was cooler to the touch) My console has an open front & there is 6 inches of space above the AVR.
My speaker wires are not crossed or strands touching (I use banana plugs.)
AVR = 110 W per channel @ 8 ohms, 20Hz-20KHz front speakers 0.2% THD.
With all surrounds (7.1) driven the specs are @ 8 ohms,110 W, 1 kHz, 1.0% THD. Don’t know what it is with my 5.1 all driven.
Mirage Speakers (5.1):
OS³-FS Floorstanding Speaker x2
OS³-CC Center Speaker
Omnisat as satellites x2
LF 100 sub Woofer
All Speakers are 8 Ohms nominal impedance with 4 Ohm minimum Impedance. RF, LF & CC can handle up to 175 Watts, Efficiency = 93dB for L&R & 91dB for CC. AVR crossover set to 100HZ. Speakers set to small.
So frequencies below 100 Hz s/b handled by powered sub & not my AVR, right?
I am using a Panasonic DMP BD80 BD player & use the 7.1 ch analog audio outputs to obtain the lossless audio from BDs since my AVR lacks HDMI.
I replayed all the audio tests from my DVE BD at -15 volume & all speakers still sound fine. The audio still sounds great. I tested a DVD with DTS sound (Behind Enemy Lines) & it was extremely loud during action scenes at volume = -15. No shut down. This only seems to happen with BD lossless audio.
I emailed Pioneer & they suggested:
“The symptom is that of the receiver overloading, normally caused by a bad speaker connection or a bad speaker.
1. Check the speaker wires, make sure the positive and negative wires are not touching.
2. remove the speakers, one at a time. Turn on the receiver, turn up the volume. If the receiver still overloads, turn off the receiver and replace the speaker. Remove the next speaker.
Continue this process until you have found that when a speaker is disconnected, the receiver no longer overloads.
If you have removed all speakers, one at at time, and the unit still overloads, the receiver will need service.”
Is this necessary? If I had a “bad” speaker wouldn’t I be able to hear something amiss during the DVE audio tests or playing music or movies? Can a speaker only reveal its problem When playing an extremely loud signal?
I’m thinking of watching movies at a lower volume & then replacing my AVR. I would hate to do this & then discover the new AVR has the same shut down/overload trouble.
Any troubleshooting ideas?
Thanks,
Steve
