Why mono?

Posted by: Steve Shochet on 09 November 2000

Here is a silly little question maybe someone can answer. Why is there a "mono" button on the output section of my 82? When would I want to listen to something in mono if it is recorded in stereo? For that matter, why is there a mono button on the record section? When would I want to record something from stereo into mono?

Obviously not a huge deal, but it's a question I have had for a while.
Thanks!!
Steve

For those with turntables and old records:

1)use the mono switch on mono lps because it will lower the effects of rumble and noise because most of it is out of phase and will cancel in mono.

2)use it on horrible "electronically re-recorded" fake stereo records where they put the treble in one channel and the bass in the other.

I guess I never even thought of that. I must admit I have some jazz albums from the 50's where stereo means dexter gordon from the left, rythm from the right. Might be less distracting in mono...I'll give it a try.

Steve:

I believe those Dexter Gordon records were actually recorded in stereo that way. They are not mono records. Quite a number of 50's stereo is recorded in 2 channels in such a manner - hard left and right with no center. The mono release of these records might even have been preferable as sometimes mono mixes are better than the stereo release.

Not all are merely hard left and hard right, with the centre missing. I find that most of those 50's and 60's jazz jobs, especially if recorded by the ubiquitous Rudy Van Gelder, have hard left, hard right AND centre, nicely recorded at least. I have no issue with this, crude as it might be with today's "soundstage" junkies. What is abominable is the "fake" stereo, such as some early Beatles, where they simply boost the treble on one channel and cut the bass on the other. Yech!! Similar travesties exist with jazz (eg "Milestones" by Miles Davis - get the Japanese mono pressing - much better).

I remember Frank once gave an interesting use of the mono button on the old forum. I hope I remember it correctly: If you're sitting off center you can use the mono button to adjust the stereo image for your new sitting place. Press the mono button, and use the balance controls until you obtain the "center" for your new sitting place. Depress the mono button and the stereo image is adjusted to your new sitting place.

Unfortunately I don't have a mono button to try it out myself, but it sounds interesting.

Ciao!

P.S. Somebody correct me if I'm wrong.

The reason for pursuing mono jazz and rock lps is not solely because stereo is distracting. "Hole in the middle" Atlantics are certainly a problem. But the mono mix is often punchier.

IIRC, for instance, Van Gelder monitored via a single K-horn until 1959 or so, even when he started recording in stereo. So the mono is likely to be closer to what he intended.

You remembered! I feel as though some of this rhetoric isn't ALL a waste of space.

Yes, you're right. The only way to adjust balance accurately is if you have a Mono switch. For those who will say that a Mono record is enough, that's not true since you can't guarantee that the output from a Mono record will actually be accurate for each channel since other issues could be at work such as cartridge out on azimuth, length of speaker cables differ, length of interconnects differ per channel etc. The Balance and Mono switch combination gets around all that.

Frank.
