Re: [Elecraft] Simulated Stereo

2021-12-29 Thread Peter Eijlander (PA0PJE) 

Hi Bob,


Yuck!


Indeed that's what I would say also.
I for one can't stand anti-phased headphones. I once discussed that over 
using stereo-headphones being fed at tip and ring and left the common 
open. The comment was: No one hears that. Well I do! Splitting mono into 
high and low pitched sound seems fine at start but fatigues just as much 
as anti-phase. Only the spacial setting on the KX3 is very useful but 
even then I like to switch back to mono at times.


Just my €0,01

Yuck!  As a retired recording studio engineer, CBS Records, having the
same signal out of phase by 180 degrees to one ear, is much like
sticking and ice pick in ones ears.

Most systems will have a variable phase shift depending on frequency,
usually not to exceed 30 degrees.   In this case, the leading phase
signal will appear from that direction.   In others, bandpass filtering
moves the higher frequency to one side and the lower to the other.  From
an audio perspective, this still sounds like "fake stereo".    It is
just messed up monaural.  There's lots of that today.

The K3S has the AFX function that does an excellent job of signal
spatialization and sounds quite nice on SSB signals.

The K3 does have several stereo functions, including something called 
"binaural" and a few delay settings. But it does NOT have the capability 
of spreading signals out by frequency like the KX3 can.

Yes, that would be great. The K3 doesn't do that, unfortunately.

The K2 and my other non-Elecraft rigs don't have the 'presence' that the

K3 gets from the ability to insert a slight delay on one side.

simulated stereo by changing the phase between the two sides.


Any *Stereo* headphones can accomplish the same thing by simply adding
a DPDT switch wired to reverse the connections (invert polarity) to
one of the two ears.

My question is: is there some kind of device that you can get that will
take the monaural audio from a non-Elecraft radio or a K2 and produce
similar effects?

Some of the various Heil headphones, including the one on the Elecraft site, 
have a switch that passively selects between mono and simulated stereo by 
changing the phase between the two sides. It basically seems to widen the 
perceived space of the sound source, possibly helpful.

If you can find one, an Orban 245 stereo synthesizer would work 
perfectly for this application.

Dale,

This works by dividing the audio spectrum into several segments and 
sending alternate segments to different channels! It wouldn't be much 
good for CW. Interesting, though.

Hello Victor,

A quick web search turned up this inexpensive ($11) thru-hole kit that 
may be worthwhile exploring.
