seti Posted December 23, 2006 Share Posted December 23, 2006 I was at a friend house earlier this week and he was spinning some vinyl as we usually do. When he went to turn the volume up but the receiver just stopped and flashed the word overload. I am unfamiliar with Pioneer receivers so any advice is much appreciated. The system is Heresy IIs, Pioneer receiver don't know the model number, and a Technics 1200 turntable. Quote Link to comment Share on other sites More sharing options...
Guest " " Posted December 23, 2006 Share Posted December 23, 2006 I wonder if this means input overload or output overload. Output overload - Is he running one pair of speakers or 2 pairs? I had a set of Hersey II's once with the round speaker terminal cups and they said they were 4 ohm speakers in klipsch lettering. Perhaps his reciever has a setting that needs to be activated for 4 ohm speakers. I know my onkyo has such a setting. Input overload - some phono inputs have settings for MM/47Kohms, MC/100ohms, MC/220ohms. They might ne a mis-match on the settings. Is he using a phono stage pre-amp?

djk Posted December 23, 2006 Share Posted December 23, 2006 You need a steep high-pass filter in the signal path. LF garbage coming from the TT tripped the DC detect circuit in the Pioneer. Quote Link to comment Share on other sites More sharing options...
seti Posted December 23, 2006 Author Share Posted December 23, 2006 He is running just one pair of Heresy speakers. I think a majority of my friends have them lol. Thanks for the replies. Quote Link to comment Share on other sites More sharing options...
Lascaladan Posted December 23, 2006 Share Posted December 23, 2006 It sounds to me that the "rumble" into the phono input created an overload to the output section. If the receiver has a subsonic filter or low frequency filter, this might help. It could also be from "acoustic feedback", sound from the speakers being put into the turntable, then reamplified. The woofers work hard and the amp sees this as a lot more power being used(clipping). You mentioned "turning it up", so that is a guess.

filmboydoug Posted December 26, 2006 Share Posted December 26, 2006 Now c'mon Duke, be fair. I own a BPC Pioneer receiver and I am sure it puts out its advertised 100 watts per channel. For at least 1 millisecond![:^)] Quote Link to comment Share on other sites More sharing options...
oldbuckster Posted December 27, 2006 Share Posted December 27, 2006 It's not the receiver, it's like Lascaladan said, it's feedback from the turntable...................move it away from speakers, isolate it somehow, or turn it down.....................
