Deang Posted March 13, 2005 Share Posted March 13, 2005 I was wondering why the upper high frequencies dip down when using a mono switch on a preamp. If it weren't for that, mono listening would be killer. Actually it's killer anyways, if anyone knows what I'm talking about here and can explain why I think so -- I would appreciate it. I'm talking about one speaker, not two. There's something really different going on with the sound, and I can't figure it out. Quote Link to comment Share on other sites More sharing options...
colterphoto1 Posted March 13, 2005 Share Posted March 13, 2005 I understand what you're saying Dean, use MONO with only one speaker, but which ear do you use? I remember an old quote from Claude Nobs, engineer and purveyour of the Montreaux Jazz Festival 'if God wanted us to listen to quad, he'd have given us 4 ears'. WOnder what he thinks of 5.1 and SACD?

Deang Posted March 13, 2005 Author Share Posted March 13, 2005 Michael -- I still use both ears! I position the speaker directly in front of me. When using a single Klipschorn, I just move the chair. Quote Link to comment Share on other sites More sharing options...
Deang Posted March 13, 2005 Author Share Posted March 13, 2005 Mark, I need to know the exact amount of rolloff and where it happens at. Do you know what and where it is? Quote Link to comment Share on other sites More sharing options...
ben. Posted March 13, 2005 Share Posted March 13, 2005 Also, keep in mind the fact that there will be phase cancellations occuring here. They will naturally have to forfeit their deposits, but what can one do? Any signals that are out of phase when comparing opposite channels in the original stereo mix will cancel each other to some degree. You'll see more of this in the upper frequencies, generally. This is a big reason why recording engineers should check there work in mono regularly. Closely similar tonal balance between stereo and mono indicates good relative phase. It's especially important when recording with multiple mics in close proximity to each other. such as drum kit micing. Quote Link to comment Share on other sites More sharing options...
fini Posted March 15, 2005 Share Posted March 15, 2005 Mark, I'm confused. I thought human hearing tapers off pretty steeply at around 20KHz. How is a difference between 45KHz and 60KHz perceivable? Quote Link to comment Share on other sites More sharing options...
Deang Posted March 15, 2005 Author Share Posted March 15, 2005 Yeah, now I'm really confused. I can't hear squat past 15kHz, so how can I possibly perceive a difference? Quote Link to comment Share on other sites More sharing options...
maxg Posted March 15, 2005 Share Posted March 15, 2005 I have never noticed a roll off with mono recordings playing back over stereo speakers anyway (without a mono switch). I guess my hearing is even worse than Dean's. Quote Link to comment Share on other sites More sharing options...
JohnA Posted March 15, 2005 Share Posted March 15, 2005 I thought the difference in HF was due to cancellation of noise and distortion that added artificial highs. I generally notice it during poor FM reception. I never noticed a difference in highs between stereo and mono with my old Yamaha CA-800 if the source was a CD player. That was the last amp I had that had a mono switch. Quote Link to comment Share on other sites More sharing options...
