Galaxy 92MHz FM played Love is the Air


Hello to Ukraine, Germany, Hellas and Russia


Producing a great vocal sound with almost any microphone at any distance





What needed is flat frequency response not from mic to loudspeaker (which can sound very bass, mid bass and treble heavy) but from singer's vocal chords to listener's brain [Lowe, Morgan].


A suitable adjustable setup could be as follows:


producer's brain - singer's vocal chords - mic at a suitable distance - passive variable slope low cut filter - small turn ratio step up transformer or input transformer to a one electron tube or JFET active mic booster - mic preamp - recorder - monitoring headphones or loudspeaker- producer's brain or listener's brain


(Making sure the following preamp is not transiently overloaded or s problems will occur).


The variable slope passive high pass filter can be a box with switchable inductors which are connected in series with a variable resistor or potentiometer. The L R in series combination is then connected across pins 2,3 (microphone's output).
Indicative values of inductance can be 10mH, 20mH, 40mH etc.
A variable resistor of 1KΩ should be adequate.


Once suitable favorite values of L, R are found, a neat and compact filter can be made inside a Neutrik XLR modules barrel, see Pleiades (R,L) filters inside XLR female to male adaptor made from Neutrik modules bought from Mouser.


The passive step up transformer can be a 1:2 or 1:3 turn ratio.


The active JFET mic booster amp can be a Pleiades K177, see schematic.


The active electron tube booster amp can be a Pleiades V6 which is powered by a single battery, see schematic including use of CV2269 electrometer tube requiring only 1.2V for both filament and plate.


An active bipolar transistor booster can be a Pleiades BC109, using the BC109 bipolar transistor as used on the EMI TG 12345 mixer.


An added advantage of above setup is very low noise ie high signal to noise ratio, world class or possibly state of the art.

Grampian GR1/L ribbon mic on close vocals





This is another signal path that produced a very nice male vocal sound with no bass or mid heaviness, excellent treble, transient detail, high signal to noise ratio, and no p or s problems.


Some low cut was done by the use of specially made low inductance transformer of about 9.7mH primary inductance and about 1:9.3 turn ratio. A very small Magnetec nanoperm glass metal ring core was used, (smaller that the Magnetec 073).


Then one K117 JFET resistance coupled amplifier was fed.


Then the extra low cut needed was done by turning the LF control fully counterclockwise on the Tascam porta 07 (running cassette at double speed) which was used for the recording.


Setup, signal path:


Male voice singing She gives me love - Whitney Houston at 4-6 in, mic also 1ft from Pleyel upright piano - Grampian GR1/L - Pleiades 9.7mH, 1:9.4 step up (high pass) transformer - Pleiades K177 booster mic pre running with 1.2V - Tascam Porta 07, gain trim at max, channel fader at max, master fader at 0dB - TDK type II cassette - Sennheiser HD 580 or Bang & Olyfsen Beocenter 2600 amp and loudspeaker

A way of creating a mic with a brain?


Mics cannot descriminate between wanted signal and noise like our brain does (see Cinema Engineering Hollywood book).


On the previous post there is a very useful trick by Lou Burroughs.



2 out of phase Shure SM63 microphones on close vocals


Is this a way of creating a mic with brain?


At your risk. Protect your hearing.


This is revisiting the trick described in the Microphones - Lou Burroughs (Electro-Voice) book on deliberately connecting 2 omnidirectional or pressure mics out of phase and singing to one of them for noise canceling and reduction of bass heaviness.


Signal path:


Male voice singing at high register - 2 SM63 connected out of phase in (electrically) series - Sony TC-D5 Pro, in mono mode - Sennheiser HD 580 - listener's (singer's) brain


Mics are connected as:
Pin 2 of mic 1 to pin 2 of preamp, pin 3 of mic 2 to pin 3 of mic 2, pin 2 of mic 2 to pin 3 of preamp.


So total impedance is 400Ω and mics are out of phase.


Then singing at about 1in from the in phase mic.


When mics are at say 2 ft apart the sound is bass heavy and there is ambient low frequency noise.


As mics are approached ambient noise falls dramatically until only a small high frequency hiss can be heard.


A distance of about 2in between mics gave the best sound with no bass heaviness and nice mid and treble detail.


Then the mics where again taken apart about 2 ft and a Pleiades (130Ω,40mH) gentle slope high pass filter was inserted between in phase mic and preamp. The sound was even more bright with less midrange.

Pleiades (R,11mH) filter experiments with the Sennheiser MD 441U3, Fostex M55RP, Electro-Voice RE15


At your risk. Protect your hearing.


After experimenting yesterday with a Pleiades (R,L) filter for the Shure VP64 (see yesterday's post) it has been decided out of duriocity to try such a (low R,11mH) filter with a Fostex M55RP, Sennheiser MD 441U3 and Electro-Voice RE15 microphone.


All these mics are of the order of 200Ω so a 1:2 transformer with 1 Henry input inductance was used to step such impedance to 800Ω and then feed the Sony preamplifier.


Signal path:


Male voice singing at a high register - mic at 1in - Pleiades (R,11mH) gentle slope low cut or high pass filter - Western Electric 1:2 signal transformer - Sony TC-D5 Pro - Sennheiser HD 580 - singer's brain as listener's brain


With the yesterdays filter set at (37Ω,11mH) the M55RP sounded amazing.


So did the the MD441 U3.


The RE15 sounded reasonant at some high frequency band. In fact the sound might had been similar to the VP64.


Encouraged by the beautiful, easy, sparkling and natural sound of the M55RP, and MD 441U3 the multi turn variable resistor was adjusted while singing in order to find sweet spots.


After finding a nice adjustment the crocodile cable clips are disconnected from the variable resistor and its value is measured with a digital voltmeter,


It is stricking that repeating the experiment 2 times with the M55RP the values measured where 19Ω and then 20Ω.


Then while performng the experiment with the MD 441U3, the value measured was 24Ω.


So a Pleiades filter of about (22Ω,11mH) gives a beautiful sound with both mics at 0-1 in.
A bright sound but with no s artifacts. An amazing sound reminding the vocals of The Power of Love - Frankie Goes to Hollywood. Or the amazing When I Fall in Love - Nat King Cole


It is amazing what can be done with just an inductor connected in series with a resistor and the total connected in parallel with the mic's output or voice coil.


This Pleiades (22Ω,11mH) filter will possibly be built inside a Neutrik module XLR barrel adaptor. The color stripe in the centre already painted by nail varnish is light green, Annie color code 257.


The (130Ω,40mH) filter used with 600Ω Fostex microphones has a blue (Annie 245) stripe adaptor housing.


What is the difference in sound between the M55RP and MD 441U3 with such a Pleiades filter?


Hard to describe in words. Both mics sound amazing. They have the detail of ribbon mics. It is surprising that the MD441U3 may have sounded even more neutral. But the M55RP has perhaps some more presence. This is perhaps expected as the MD441U3 has a flat frequency response.


If a Pleiades Fikter is not connected, all that can be heard is bass and mid exaggeration by the well known objective and subjective effects described in the Lowe, Morgan paper.

Hello to Germany, Hellas and Romania


The power of love


The Gabriella Aloin cover version is in B minor (so that female voice remains warm at a low register). B minor means that only F and C and A are sharp.
So chords move from B to G7 ie B D #F to G B D #F
https://m.youtube.com/watch?v=zNpeK7sDLzE


The original version is in F minor which best suits the male voice to shine on a high register.
https://m.youtube.com/watch?v=NyoTvgPn0rU
See older posts for figured bass (chords).

Crowley and Tripp microphone patent


After reading the Wes Dooley interview (link in yesterday's post), Crowley and Tripp ribbon microphones were mentioned, technology bought by Shure.


Then a Mixonline article revealed some patent titles.


A European espacenet patent office search found this patent:
https://worldwide.espacenet.com/publicationDetails/originalDocument?CC=WO&NR=2006047048A2&KC=A2&FT=D&ND=3&date=20060504&DB=EPODOC&locale=en_EP









Shure VP64, Fostex M80RP and Pleiades filters


At your risk. Protect your hearing.


For many or most applications any mic may need a gentle slope low cut filter.


A directional mic will need it due to the proximity effect and also for subjective (Fletcher Munson) and voice production voice effort spectrum curve compensation [Lowe, Morgan].


A non directional mic will need the gentle slope low cut filter not for the proximity effect but for the other effects.


On previous posts it had been described that a suitable gentle slope Pleiades (R,L) filter for the Fostex M80RP, M88RP both 600Ω Japanese versions is a (40mH,130Ω)


Can a Shure VP64 omnidirectional microphone sound as good or close with a suitable choice of R L values ie Resistance in series with inductance and the total connected in parallel with the mic's output?


This test are done while singing which normal needs more low cutting than speaking especially when male voice is singing in a higher register (counterintuitively). But this is what seems to be happening in practice while singing and listening through headphones in real time.


The Fostex M80RP, is possibly 600Ω. The Shure VP64 is about 300Ω. It was stepped up by a Western Electric 1:2 transformer to 1200Ω using a previous setup used for the Shure Unidyne III, see previous experiments.


Signal path:


Male voice singing Πως θα Ηταν in F minor ie first voice note is high C - mic at 2-3 in - Pleiades (R,L) gentle slope low cut filter - WE 1:2 transformer used only for the VP64 mic - Sony TC-D5 Pro - Sennheiser HD 580 - listener's brain


As mentioned above a nice sounding Pleiades filter for the Fostex M80RP is (130Ω,40mH)


A nice filter found by experiment for the VP64 is (37,11mH)
The sound is very loud, bright, harsher than the Fostex M80RP with no bass heaviness.


Other useful combinations are (64Ω,11mH,), (29Ω,11mH), (42Ω,11mH) and (25Ω,3.8mH) which is more bright.
The (130Ω,40mH) was tried at 1200Ω, nice but perhaps harsh. 2 Pleiades filter were also tried in cascade ie (130Ω,40mH) and (240Ω,11mH) but still the low resistance 11mH filter was preferred.


Very good quality sound is possible with just one Resistor and Inductor added to a mic line.


The omnidirectional moving coil seems to sound loud and clear with some or little harshness at high frequency but cannot match the smoothness or HF detail of the coil ribbon mic. Both mics sounded great.


Latter addition: Such Pleiadss filter with low resistance and 11mH inductance sounds also very nice on the Sennheiser MD 441U3 and Fostex M55RP, see next day's post.

Stereo headphones output from Yamaha DX7 II.D


The trick is to connect 2 1/4in jacks to the L R line outputs to make the synth understand you want it in stereo mode. Uncabled 1/4in jack adaptors may be used.


Then headphones will play in stereo too.


For example one patch can then be sent to left channel and another or the same patch to right channel.
This is done by used the Dual, Pan press knobs etc accordingly, see operating manual.


The same patch sent to each channel makes for a very nice stereo effect.

Hello to Germany and the United States


Comparing various mics while singing a higher pitched phrase of Freelove - Depeche Mode




This is the first time on a Pleiades test that a made in Mexico Shure mic beats one made in USA.


As many microphones as possible were tried as quickly as possible on such a subjective auditioning test.


Here it is:


Signal path:


Male voice singing the high pitched phrase "Hey Girl" from Freelove - Depeche Mode, in the correct key - mic at a distance from 1-2 in to 12in - Pleiades (130Ω,40mH) gentle slope high pass filter - SONY TC-D5 Pro preamp in mono mode - Sennheiser HD 580 - Singer's ears and brain


Vivanco DM200
Not bad at all, very bright, interesting.
An x(-1) adapter was not used as this mic is internaly wired out of phase.
(The particular Sony TC-D5 used phase reverses from XLR mic in to phones out).


Fostex M80RP
Possibly the best on this test, smooth, detailed, a sense of the good side of a good condenser mic too, no bass problems.


Revox AKG variable D, D19C/200
With its low cut on, at higher distance.
Amazing, very loud, detailed.


Beyer M119
Big but confused sound.


Beyer beaten up M61
harsh, resonant


Sennheiser MD211 omnis, 2 were tried, one with more bass
Too much bandwidth


Fostex M55RP handheld printed ribbon
More bandwidth than needed but much better.


RadioShack, made by Shure omni
Very nice.


RadioShack 33-3039 omni
Great.

Audio Technica AT802 omni
Nice.


Audio Technica AT804, Lanier (better one), Lanier, AKG D130 omnis
Harsh.


Beyer Dynamic M88
Very very loud.
Very nice at a higher distance.


Shure Unidyne III
Nice but a bit harsh like on Pet Sound's album use of this mic by Brian Wilson.


Shure 515SB, made in USA
Very nice but a bit bigger than needed.


Shure SM58, made in Mexico
Same to worse.


Shure 515SB, made in Mexico
Great, one of the best mics on this test, in fact it was used as reference due to its neutrality, smooth sound, treble detail, no bass offensive problems.
The first mic I have ever bought?


Beyer dynamic M260.80 (ribbon)
Amazing detail and naturalness at higher distance without the Pleiades filter.
Somewhat bass heavy.
Drills etc picked up from a far off block of flat's works in progress, sounded amazing.

Revox M 3500 600Ω
Too bright.
Without a Pleiades filter better at a distance of 2ft but room acoustics spoil the result.


BRC (ITT?) small Omni mic
Resonant at mid range.

Shure SM63
Very nice, very extended treble, very loud.

Paso M601 M
Very harsh.


Shure VP64
Nice and big.


Criticism of this test:


Different impedance mics will react differently with the particular fixed (130Ω,40mH) Pleiades filter. In fact this test may be an effort to find the best sounding mic with the particular filter for the particular male singing voice at a high register.


Subjective conclusion:


We are trying for something that has already found us - Jim Morrison.

The first mic I had ever bought sounded perhaps the best and most natural on this application.
I could not have appreciated this 20 years ago as I did not know at the time what a Pleiades filter is or could do (an inductor in series with a resistor connected in parallel to mic's output to reduce subjective bass heaviness).


The beaten up Fostex M80RP flat coil ribbon sends to the cleaners most of the mics on this test. Loud too. Smooth and detailed.


Most of the mics on this test without a Pleiades (R,L) gentle slope high pass filter sound like a cheap cassette recorder electret condenser mic. Conversely a cassette recorder with a good dynamic mic connected to a Pleiades filter can sound like a finished product.


The best singer in the world with an unsuitable or wrong signal path may sound incompetent.

Freelove - Depeche Mode


https://m.youtube.com/watch?v=xZ3nJ6KhWOo#



Hello to Germany and Hellas


Making music simpler


Why using 4 part harmony when 2 part harmony can be used?


This idea came about while trying to accompany singing Freelove - Depeche Mode on glockenspiel using just 2 mallets.


It sounded great!


In fact it is 3 part harmony.
The male voice and the 2 notes played on glockenspiel.


In fact it is more than 3 part harmony as the notes on glockenspiel sustain a lot. So while playing the new notes then previous ones as still subtly there. This creates amazing prepared intervals which sound great.


What was played on glockenspiel goes somewhat like this:


D F        if you' ve been hiding from
D bB      love
D F        if you' ve been hiding from
D bB      love
D bB      I can understand where you're coming
C E        from , i can
bD  F     understand where you're coming from
C bE

D F  (similarly 2nd verse)

         and I'm only here
F bA
F bE to bring you
bB F freelove, let's make it
F bA clear
F bE that this is
bB F freelove, no hidden
bB F catch no strings att-
C bE -ached, just
F bA freelove
bE bA no hidden (bE is passing bass note)
bB F catch no strings att-
C bE -ached, just
F bA freelove



etc


When the next note to be played is the same as the previous it can be not played as it already keeps singing


It is very easy.


All that is needed is knowing the bass code of the particular music.


And knowing the scale ie what flats or sharps for which note.


For example if the bass code is C7 we play 1 3 5 7
C bE G bB (E and B are flat as on chorus the scale is F minor)

Bach Bass Rules - Bach, Niedt, PDF



Harmony - Piston










The bass code of Freelove - Depeche Mode



This only thing needed to play perfectly any music is to remember the rule 1 3 5 7 9 etc above bass but actually play the least needed for an intellectually simple result.


For example the beginning of chorus of Freelove - Depeche Mode:
All needed to know is that the bass is F.
(The scale or key happens to be F minor ie all notes A, B, D, E are flat).
So using the rule 1 3 5 ...
We play:
Bass F and F bA C
We may omit the F as it is already on bass and so play:
Bass F and bA C
We may omit bA as it happens to be sung, and so just play:
Bass F and C  ...here, to give you...


B7           Freelove


Here is the bass code ie full harmony of Freelove - Depeche Mode:


D minor key (ie all B are bB)

Every bass note last 4 beats
Verse:
D
B
D
B
B
C
Key becomes F minor (bA, bB, bD, bE)
B7 (ie this means bass bB with bD (and F) and bA)
C7 (ie this means bass C with bE (and G) and bB)

Chorus
F

Addition to the Pleiades Meal


At your risk. This is not a medical advice.


Addition of 100% organic cocoa powder. Criollo variety. (It is amazing what one can buy with just 3 euros).


A hint is to add the dry cocoa powder to the crushed oat flakes and other ingredients, stirring before adding the filtered water and a bit of sea water.


Together with moist oats it creates something tasting like chocolate milk.
Quality food can taste very nice too.

4 voice harmony, Air - J. S. Bach


Air on the G string (with score)
https://m.youtube.com/watch?v=E2j-frfK-yg#fauxfullscreen


A few hints to understand what is going on are the following:


The composition is in the key of D major. Ie all notes are natural except F which is F sharp.


Bach used step bass and at the same time bass moving up and down in octaves.


While the bass moves step by step other voices may remain constant creating for example prepared 7ths, 9ths etc.


Together with a 7th, 9th with respect to bass, the 3rd is added by another voice (part or melody).


For example at the beginning the violas and the violins play A D #F ie the chord D major (derived by the simple 1 3 5 rule with respect to bass D, ie D bass and D #F A).
Bass steps down the scale note by note while other parts remain A D #F. When bass becomes B the part playing A becomes B ie parts play again 1 3 5 wrt bass, the B minor 3rd chord.
Then bass keeps going step by step down the D major scale. Upper parts already play B D #F which is really looking ahead to the creation of the G B D #F chord when bass eventually becomes G. This fantastically sounding chord is therefore ingeniously prepared for the listener's brain. It is called G major 3rd major 7th, the name derived from the name of the intervals of the other parts with respect to bass.


Throughout the composition exquisite musical intervals such as 9ths with respect to bass are created in a prepared way for the human brain and another part or voice is then simultaneously playing the interval of 3rd with respect to bass.

Revox M 3500, another mic without an LRC filter needed to reduce high frequency peak


At your risk. Take all safety precautions. Protect your hearing.


https://www.gearslutz.com/board/so-much-gear-so-little-time/462601-revox-m-3500-dynamic-mic-vs-beyer-m-201-a.html


According to above discussion the M201 uses an LRC filter to tame the high frequency peak.
(Later addition: it still has a peak, see datasheet:http://www.preservationsound.com/wp-content/uploads/2017/10/Beyerdynamic_1974.pdf)


This LRC filter can be seen in the datasheet:
http://recordinghacks.com/pdf/beyerdynamic/M201_BA_DEF_01.pdf


A similar LRC filter used inside an SM7 to create flat electrical frequency response.
http://www.coutant.org/sm7/sm7.pdf


(L is series with R in series with L is connected in parallel to moving coil output, as seen in above Shure SM7 datasheet).


It may be interesting to create a Pleiades in line Neutrik module LRC filter for the M 3500 microphone.

Electron tube DF97 at low supply potential?



At your risk.
Take safety precautions.
A fuse should always been used in series with a battery for fire protection.


An dvantage of such electron tubes is the low filament current consumption, typically less than 25mA if underheating is used.


Some preliminary measurements were done today. DF96 has not been tried yet.


Supplying 1.5V at filament cathode.


Then control grid left open (at space potential).


Then screen grid used as anode electrode.


Vg2        Ig2
9V          0.1μA
18V         1μA
27V        18μA
36V      106μA
48V      350μA


Vb is approximate as 9V batteries were used in various discharge state.


Then an 8.2MΩ was connected between Vb and grid for pull up bias or Pleiades Bias.


Vg2          Ig2
9V            26μA
18V        122μA


A microphone booster amplifier such as Pleiades V6 should be possible even at Vb=9V.
