Need more Mic volume on S975
« on: June 05, 2018, 09:36:13 AM »
I would appreciate some ideas from you S950, S97x owners.

With my S910, I could get all the microphone volume I wanted...and more.

But with my new S975, I can't get adequate volume without turning up the keyboard's master volume knob.

Here is what I currently do:

GUITAR/MIC SWITCH:  Set to Mic.

GAIN KNOB (Next to guitar/mic switch): Turned all the way up.

MIC ACCESS BUTTON:  Talk is turned off.

COMPRESSION:  Talk is turned on.

LEFT LIVE CONTROL KNOB:  Assigned to volume control, which controls the Mic setting (on the screen for controlling volume settings for Style, Pads, Left, Right 1, Right 2...) and is set to 127.

Have I overlooked something?

Thanks for your thoughts.

Hi Royce,

I approach controlling the mic volume by turning the STYLE down. I have always said the keyboards are set up for playing the keyboard and not really for using the Mic and singing.

I set the style Master Volume for just the "style" at 68 and the Mic Master Volume at 100. This does require you to reset the OTS settings at a lower volume as well.

Then I turn the MASTER VOLUME knob for the whole keyboard at 75 percent.

It's not that the mic isn't loud enough ... it is the keyboard is too loud. ;)

Regards
Drake

While the SM58 was a great mic way back when, by today's standards it's at the bottom of the heap. It has very little gain, thus you will have to use some sort of booster to get the needed volume for that keyboard. You would do much better with a Samson Q7 or Q8, which sells for about $50 to $75 on most internet sites.

Good luck,

Gary :cool:

Gary, I was hoping the problem wasn't something like this, but I think it has to be. Surely I've covered the relevant areas on the keyboard--unless somebody notices something I've overlooked.

I will read up on those microphones.

The Samsons have a little more gain, as Gary said, but I've had no problem getting enough volume from SM58.  I don't use them any more, but i just plugged one in and tried it and it worked fine.
I have all the main settings at 100, including mic, but there is plenty of room to increase the mic volume.  You should NOT have to turn the input knob all the way up.  Are you certain the switch is in the MIC position?  Could it be broken?  Just fishing for possible causes, but it seems to me that the style settings may be set too high, as Drake suggested.
Also you might try resetting the mic settings to factory default.  Maybe the volume got turned down there somehow.  For example the mic/harmony adjustment might have gotten turned too far toward the harmony.

Hi Royce, a freind of mine have a S970 with the S SM58, and this Mic is very powerfull!just check if the mic settings is set to Mic/Guit in the  DSP section (Harmony button); if not the sound is very Week! Then adjust the volume of your microphone behind the keyboard as it must not be to loud! Try Garry's settings, very good choice; have you adjusted you're EQ settings? I hope you'll found the best settings, all the best Patrick

NB: Vocal harmony/Effects type/Assign part change Right 1 to Mic/Guit/Type: tempo echo (or try some others type)

No problems, here, with the S975----nor with the 970 and 950 prior to that.  I follow Drakeís advice on balancing all factors to allow the vocal to cut through.  For mics, Iím having good success with the TC Helicon MP-75.  It rejects feedback issues very well.  I used the Shure Beta 58 for a long time.  Like the MP-75 much better.

Look for mics with 'neodymium' magnets in the element. These will generally have  a higher sensitivity/output which is expressed in dbV/PA or mV/PA. The SM58 has a sensitivity of -54.5 dBV/Pa or 1.85 mV/PA. A few neodymium magnet mics will be up towards 2.2 mV/PA or higher and will need less gain in the preamp. A handheld style condenser may be even higher sensitivity. A few handheld condenser mics may use a battery so phantom power is not needed.

Most often the SM58 is used handheld by the singer and usually quite close to the mouth (kissing the grill) where higher sound pressure levels can create a higher output from the mic. Most here that play keyboard and sing may have the mic a bit further away which will need more gain from the preamp to compensate for a lower sound pressure level or a mic with a higher sensitivity.

Some mics are definitely more sensitive than others, but I still maintain the SM58 shoud work. 
I have used one, also two Samsons, Q7 and Q8, three EVs, including 967, two Sennheisers, a lowly Behringer, and probably more that don't come to mind.  I am a mic freak.
Point is they all worked with several PSRs, including 8000, 2000, 2100, 900, 910, 950 and 970, and all that was necessary was adjusting the input knob.
Something either isn't set correctly or something is wrong.

Everybody,

I so appreciate all your thoughtful replies and information. I don't think I mentioned that I use the mic for PA only...I do not sing (the nicest thing I do for my audiences).

I'm going to do three things:

1. Check through everything on the S975 again.
2. Try a new mic cable that I have in storage.
3. If problem continues, I will take my mic to my local music store and try it on their demo unit.

I will report back.

Meanwhile, please let me know of other ideas you might think of.

Thanks again,

Hereís something I just tried with my S975 and it works very well.  Iím running a Shure Beta 87A condenser mic through a small, tube pre-amp (Art).  It has phantom power.  Then, run a ľĒ cable output to the mic input of the S975.  Balance everything and presto, nice clean vocals.  Plenty of gain to work with.  Wouldnít it be great if Yamaha would put an XLR input with phantom power on the PSR models?  Maybe thatís too much to wish for or expect.

REPORTING BACK

None of the above items was a solution. While at the music store testing my mic on their S975, the owner was sure there was another volume control somewhere...and he found it.

SOLUTION

The following gets you to another volume control:

1. Press Direct Access Button.
2. Press Mic Button.
3. Press Talk Tab (at top).
4. The volume control is at the bottom left of screen.

Glad you found it.  I had forgotten about it I guess.  But I was 100% certain it wasn't because of the Shure mic.  I don't use it any more, but it has been the industry standard for more than 50 years.  Never thought about your having it in "talk" mode.
I did get a counterfeit SM58 once.  It still worked o.k. but had awful handling noise.
I still would think that a factory reset would have done the trick.
Glad you got to the bottom of it!

Hi
 sounds as it working for you ,I think the out put makes a big difference !!! again  71 out with mic volume set at about 107  and mic guitar gain in back of key board set in center, is perfect for me,The mic you are using also is responsible for your volume I am now using a Electra Voice (EV)Nd 967  my opinion a great mic ,with a price of about $200.00 and have lots of mic volume
as Ronnie suggested  by boasting the volume in the mic mixer up it sounds as though you have solved your mic problem

Thank you, Paula.

I've not yet tried the new settings while doing a program. Even though tests at home are louder, I am concerned that I'm having to turn all 4 controls up to maximum (not counting the master control knob).

Couple this with the apparent MIC/GUITAR input switch anomaly (as I've noted in another thread) in which no volume change occurs when flipping the switch from guitar to mic, I am beginning to have serious thoughts that the S975 has a design or manufacturing flaw in which a pre-amp type of function for the mic is failing. Both my unit and the one in the music store behave similarly.

As I've said before, I really appreciate folks' input on this issue.

Thank you for doing that test, Paula.

Monday I will get to hear my mic setup at a gig (my living room is an absolute sound sponge). I'm expecting to find things to be satisfactory now that I understand the various points of control.

Regarding my MIC/GUITAR SWITCH question, I spent some time at my local music store again today. The owner discovered that other models of keyboards behave the same now--no detectable volume change when flipped. So I must conclude that this is by design...end of question.

Probable impedance mis-match

I just went through the same thing on my new PSR-S970, trying to use a Shure Beta with a regular XLR-1/4" TS adapter. Not enough volume. I was searching through my things and found one of my old impedance matching transformers, and voila, the mic is working great through the keyboard now. Here's one available on Amazon:
https://www.amazon.com/CP8201-Microphone-Impedance-Matching-Transformer/dp/B0002CZYFC/ref=sr_1_1_sspa?s=musical-instruments&ie=UTF8&qid=1528598022&sr=1-1-spons&keywords=impedance+matching+transformer&psc=1&smid=A2O1A8NNN5Y1TU

The input on the 970 is high impedance and the SM58 is low impedance. You need the matcher to get the right sound. Hope this helps...

It's a good mic.  You might check out Samson Q8.  I like it about as well as anything, even much more expensive mics.  Since Q8x came out, the Q8 can be found at great prices.  I have two Q7s and a Q8.  I will probably get a Q8x just to see if there is any difference. 
I just counted and have 14 mics setting around!  :)   And I have donated or sold about 10 in the past year or so.

Thanks, Paul.

I followed up on all the mic suggestions members gave, but decided to go for a Sennheiser E 845S Pro Performance, which is probably an overkill. I prefer an on/off switch, because of the way I use a mic, which didn't appear to be available on most of the suggestions.

Price wise, a number of sellers have the same reduced price, so I bought from Sweetwater with whom I've done business in the past.

Regarding this entire thread, I feel like I've gone the "long way around the mountain." In the process I've learned so much more than I would have otherwise, and I hope someone else will benefit from it. It has demonstrated the wealth of experience and wisdom available on this forum.

Thank you everybody!!

Royce, I think you will find you still need an impedance matching adapter or cable. It will make a tremendous difference in the sound, as your new Sennheiser is low impedance. Low impedance mics are superior to high impedance and widely used in all professional applications. That is my opinion, but I did sound for my various bands for years before retiring from the profession. Also do a search on high vs. low impedance to learn more. If you intend to use it with your keyboard, I would invest in a high quality XLR mic cable and the impedance matcher at the link I posted above or a comparable one.

Just my $.02

Jay,

I value your $0.02. I was intending to take your earlier information to heart, but my ignorance might be rearing up to bite me in that I was hoping this mic would jump the impedance hurdle without using the impedance matcher.

I tried to sort it out and even talked with people at Guitar Center and Sweetwater who seemed as in the dark as I regarding low vs high impedance of their mic products.

For now, I will have to wait and see how the Sennheiser E 845S compares with the Shure SM58 on my S975.

Thanks,

Hi Royce,

I don't mean to be a persistent pest at all, but this is important. The difference between a low vs high impedance mic is described here by Audio Technica > https://www.audio-technica.com/cms/site/214c5c52432bc79b/index.html

I found this matcher on Amazon for less $$$ > https://www.amazon.com/Shure-A85F-Transformer-Female-4-Inch/dp/B0006NMUHW/ref=sr_1_2?s=musical-instruments&ie=UTF8&qid=1528799084&sr=1-2&keywords=impedance+matching+adapter#customerReviews

Read the first review on this product, it sums up my point nicely.

You will find that you have much more headroom to increase volume and better signal to noise ratio using this.

Royce,

I just read the last couple of posts from Jay B. and a little light went on in my head. (its usually pretty dim up there  :))

I bought a balanced mic cable from my local music store to use with my 970 and my mic(s) and it presented the same characteristics you have been describing. I returned it and went to another store (Music Go Round) and purchased an unbalanced cable that has a marking on it that says "Pin 3 Hot". That cable worked perfectly with all my mics. I have since bought several other similar cables and all work fine.
This was 2 years ago when I first bought my 970 and I had forgotten all about it. Your problem may just be your cable and perhaps the device described by Jay B would solve the issue for you cheaper than a new mic.

Good luck,

Paul, glad you brought that up. Over the years I have posted this information so many, many times. You would be amazed at the number of folks that have been sold the wrong adapter cable at both music stores and GC. In every instance, the store clerk had absolutely no idea of the difference in the cables.

Sadly for a major instrument manufacturer Yamaha can't or doesn't want to be bothered giving the specs for the mic input of their arranger keyboards in the user or reference manual. I did download the service manual for the PSR S950 which does show the acceptable microphone input impedance (150  to 600 ohms). I suspect the S975 is the same. No impedance matching transformer or cable is needed. To properly connect an XLR connected low impedance mic, typical of most currently available mics, an XLR to 1/4" TS cable would be the one to use where the XLR pin 3 (low) is tied to XLR pin 1 (ground) and is connected to the 1/4" sleeve. Pin 2 (hot) is connected to the 1/4" tip.
A Hosa-PXF-105-XLR3F is one I've been using.

Either of the two ways in the link below will ensure proper polarity/phasing of an XLR to 1/4" TS plug.....

Is my head swimming yet?

However it turns out with my new mic, you folks are providing me a great education...for free!  Jay and MarkF, I appreciate your detailed submissions.

My mic is supposed to arrive tomorrow (the suspense builds...); I'll report back with my opinions.

Royce, if you have access to a multi-meter, check out your cable and make sure it is an unbalanced cable, with pin 3 connecting to the tip of the 1/4-inch plug. This is very important - no impedance matching transformer needed.

Good luck,

Gary,
That can work with pin 3 to the tip, but it reverses the polarity/phase of the signal (not a big deal if it's the only mic). The usual convention is pin 2 is considered 'hot' and that would connect to the tip of the 1/4" plug.
While the link below is for an XLR to TRS balanced cable, it still is standard for an XLR to 1/4" TS unbalanced to have the tip 'hot' from pin 2.

...and as an ex-professional sound tech as well as musician, I have to insist that balanced mic cables are superior to unbalanced for microphones. They eliminate noise, cancel out distortion, allow for very long cable runs, etc. Audio professionals do not use unbalanced mic cables. Unbalanced cables can be used for instruments, audio sources, etc. but you still run into noise, and possible distortion if the runs go over 15-20 feet.

To further bolster the point, here are some other sources to review:
Sweetwater > https://www.sweetwater.com/insync/cable-buying-guide/     Read the Balanced vs. Unbalanced section
https://www.epiphan.com/blog/audio-cables-balanced-vs-unbalanced/  > Scroll down to read a nice summation of the pros and cons
https://ask.audio/articles/music-studio-essentials-understanding-balanced-vs-unbalanced-xlr-cables    >   Another article to gain understanding

Bottom line - if your new mic does not work with your current cable, I would recommend using a balanced XLR cable and an impedance matching adapter.

Not trying to offend others here as this forum has some of the nicest folks on the 'net, but teach from professional experience.

Thanks Gary. I know for a fact that my cable is unbalanced.

NEW MIC REPORT

First I would like to comment that on Monday I got to use my old Sure SM58 with the new settings we've been discovering and discussing. I was surprised at how well it did outside of my acoustically absorbent living room.

The new Sennheiser e 845S mic arrived today. I set all settings to defaults and gradually increased them. I left those settings in place then alternated mics a couple times. The 845 seemed a little hotter and a little richer in sound. Having done this comparison, I realize I really could have gotten by with the SM58 with the new settings. I can comfortably live with either mic...except my grandson thinks he needs my old SM58.

Question for Jay B.

I don't know whether I will attempt your suggestion, Jay, but I am curious as to the exact cable configuration you suggest with the impedance matching transformer. In my case, I use a short cable (6 ft). The transformers you referenced seem sizable and perhaps could be a bit awkward. Would you please comment. It would help round out all that's been said in this tread.

Thanks,

- Royce
