Hi
Still thinking about this situation.
If you did get the ebbtech buzz eliminator can you put a lead in from the keyboard and out to the pa DXR 8.
I read In native instruments section that you must not connect a lead from an amp to a speaker.
The amp is in the speaker so what is the situation there.
Also does a cheaper buzz or hum eliminator degradate the sound  from the speakers???
I am not too worried about this as backing off the speakers to just under a quarter volume  and turning up the Genos to 12 '0clock you get sufficient volume for a room and the quality is 100%.
It would be nice to kill the buzz as I might want to do a Deep Purple or a Black sabbath sometime. Not Motorhead, they work at 0 db and the ceiling shakes which takes a couple of days to get over. 8) ;D With a Motorhead concert ,you need to see an ear specialist afterwards , not Specsavers ;D My son in Law dragged me to a Motorhead concert and I have never been the same agaiN!!  :P ::)  " Mean looking mother in a black leather jacket""!! wooowowowooowoZING!! ;D  " Ace of Spades" Yeah!! :) Reginald Dixon Nah!! ;D

Hi
A mic input .
I am confused here
I asked whether you can go from keyboard outs to Di box in and to the Powered speaker as I am getting the buzz from the speaker.
I red that from amp to speaker is dodgy,. It is hell if you are not electrically minded and I have a horrid cold !! :-[
I am not talking about mix consoles etc.
I am not up to speed with the tech and need an explanation that is simple like a little drawing would help
I do not want to blow anything up or degradate the sound from the speakers

Hi Tommy,

Thanks for the links - they are very useful to me.

So, I guess after you watched the Youtube video on the positive review of the US$149 Radial ProD2 Passive 2 Channel Direct Box and the guy's painful experience with cheap DIs, you removed your link to the inexpensive Behringer Ultra-DI DI600P.  :)

That was the reason why I quoted the US$179 Countryman Type 85 DI, and we need 2 of these for Genos - too expensive solution.  The Radial ProD2 Passive 2 channel DI is much more affordable, with proven track record.

I think its safe to say...when you have spent very good money on a new outfit like you have john then using cheep gear inbetween will only act as the weakest link and after trying one or two of these Di's in a passive configeration over time and passive being best for a keyboard.. then there are differences in tonality and after trying a few there are changes in the dynamics... Radial is especially good and for a few quid more why risk choking the fidelity of the Genos with cheaper gear...all the pros use Radial 😊

Hi John,

On the video, I could see that the guy implied to connect the high Z unbalanced left and right outputs from Genos to the DI boxes, then the DI boxes connect to a in-house mixer using low Z XLR cables, then from the mixer, you connect either balanced 1/4 inch cables or XLR cables to your powered speakers.

Thanks,
Paul

Hi John,

In your case:
Genos unbalanced outputs - unbalanced high Z 1/4-inch cables - DI boxes - balanced 1/4-inch cables, or XLR cables to your powered speakers.

Hi Paul
I have looked on Amazon and can see the cables you put down
What is this about never go from amp to di box to speaker as you will damage them.
But I will be going from keyboard to di box and then to powered speakers.
Sorry paul I am a novice at this and i did not know the difference between balanced and unbalanced.Why is their not a standard!! :)

I have made a bit of noise about Genos at this price point not having balanced outputs and Yamaha have only just catch up with every one else with the montage which now has balanced outputs....so unfortunately a Di will be needed and most probably in this case will hopfuly sort this problem out...

Thanks tom for your help
One last thing
What is it that you must not connect amp to speakers with di box in between,which could damage your gear with electrical terms I do not understand.
Came from Native Instruments pages.

If all ok as you have written I shall go for the Ebbtech  one you recommended as I believe cheap is cheap and you get what you pay for.
I also read that cheap ones like paul wants could alter your sound. Is that right ??  You cannot cut corners with these things.
Otherwise big thanks for your help
The Dxr8s are quality,I can say that as the stereo field is engulfing. Great for ambient music, like the Ozric Tentacles
At low and  medium volume the sound sweeps accross the speakers side to side with panache.
Also good taste In music you have. May the Pink Piggies fly!! :D . and the aero gozzers fly down the wires!!
You need to get Jean Michel Jarre London Docklands out next!!  I still have the VHs without a player!!,but I copied it ages ago.

INTO the Genos is still a prosumer class of device and thus the unbalanced outputs which fit better in a home environment. On another front the Genos touchscreen is much better than the one on my Montage.

Hi John,

I like the simplicity of explanation on balanced vs unbalanced audio cables at this site:
https://www.epiphan.com/blog/audio-cables-balanced-vs-unbalanced/

You mentioned:
"What is it that you must not connect amp to speakers with di box in between,which could damage your gear with electrical terms I do not understand."

Please note the following different Genos, cable, DI, mixer, amp, speaker configurations:

1.  Conventional setup with a mixer, power amp, and passive speakers:
Genos unbalanced outputs - unbalanced high Z 1/4-inch cables - DI boxes - balanced 1/4-inch cables, or XLR cables - in-house mixer - balanced cables - power amp - speaker cables - passive speakers

2.  Conventional setup with a mixer, and a pair of active near field monitor speakers or powered PA speakers:
Genos unbalanced outputs - unbalanced high Z 1/4-inch cables - DI boxes - balanced 1/4-inch cables, or XLR cables - in-house mixer - balanced cables - powered speakers.

3.  Your situation, without a mixer, just Genos and a pair of powered PA speakers:
Genos unbalanced outputs - unbalanced high Z 1/4-inch cables - DI boxes - balanced 1/4-inch cables, or XLR cables - powered speakers.

From the above, you can see that there is no DI boxes in between a power amp and a pair of passive speakers.  As long as the DI boxes are used before the amp, not in between the amp and the speakers, you should be fine.  The only links between power amp and passive speakers should only be speaker cables.

Thanks,
Paul

not really should have balanced at this level and the montage screen.. yes we just missed the Genos nice big one and would of been nice if they angled it like Genos ...next time perhaps 😊

You seemed to be mixing up the hum/buzz eliminator and the direct boxes.  The following discussion thread is a good start:
http://www.harmonycentral.com/forum/forum/LivePerformanceCategory/acapella-33/372800-

I ordered the $38 "Rolls HE18 Buzz Off Dual Channel Hum & Buzz eliminator" to see if it removes hums as claimed, due to good Amazon user reviews.  I also ordered the Radial ProD2 Passive 2 Channel Direct Box, which I think is more useful to me because it is reported to be significantly better passive DI box than the Whirlwind Imp 2 that I used before.

I will let you know the testing results when I receive them.

Thanks,
Paul

Because I'm making reference to the Radial Pro D2 one other thing to consider if you don't have much experience here then once you have your left & right jack cables coming from the Genos into the Radial Pro D2... then from there your left & right XLR outputs (Pro D2).. into the "left input no.1" XLR on DXR8 and the "right input no.1" XLR on the DXR8 you will probably find you will need to switch on Both L&R DXR's the small toggle switch from "Line" into the up position "Mic" when using the Mic line level from the Pro D2 ....at this point before you switch on the power...turn the Genos Master panel volume right down to "0" and gently bring the volume up on the Genos in this new configeration....as for the DXR's volume setting this will depend on how close you are to them but equally the same level settings on both DXR's ...😊

Hi Tommy,

It is very nice of you to even mention these small details to help John out.

The key is always turn on Genos first, before turning on the active speakers.  This way guarantees no annoying popping sound from the speakers when we power Genos on.

It is of course a best practice to minimize Genos master volume control when powering it up.

I actually tested the Genos with different master volume levels when powered on.  Yamaha did a good job in designing the power on process of Genos, I found that it never really introduced any loud pop sounds to the already on external speakers.  I could only hear some sort of white noise when the master volume knob of Genos was set past 12 o'clock position when powered on with the already on external speakers, but no loud pops occurred. 

Your mileage may vary though due to different designs of speakers, so please do not hold me responsible for any unfavorable testing results on your side.  :)

Thanks,
Paul

I would like to know if your buzz /hum eliminator gets rid of that zzzzzbuzz or do they call it hum ??
By using unbalanced cables and balanced to the speakers.
The Ebbtech seems to be the jobby  as we only want to elliminate the annoyance, not to change the sound from the speakers In any way
I am sorry if I am a little naive with all of this as if you are not electricall minded , it can be a headache sorting  out electrical cockroaches in the wires.

Hi john I have the same set up as yourself, like you I was experiencing the same problems I have installed a behringer micro hd 400 hum destroyer on short leads from keyboard then longer jack to jack leads to drx8 first speaker then joined the other drx via a xlr male to xlr femail cable from the link out on speaker with the leads from keyboard to mic/line on second speaker then set DSp switches to off and stereo to on . The sound from these speakers is fantastic with a little noise from the cooling fans but no buzz/ hiss my room size is 27x12 hope this helps you.    Marshall

Hi Marshall
I was beginning to think I was the only one with this set up. At first I thought these were total overkill and now I have changed my mind.
Apart from the teething problems now is the time to look at the sound seriously. Looks daunting at the moment.
These speakers give so much detail , but I am having beginners problems in getting the eq right on the button.
It is a case, I know of trial and error, but these speakers can be heavy on your ears If the bass is too much and not balanced.
The thing I do notice with the Genos as with the Tyros the kick drums are too loud and sometimes monopolise the drum channel.
So I will go to the edit Channell and lower them for certain styles and put them In the user section.
My Vst's sound fantastic as well.
I was was playing around with the acoustic concert guitar and being new to this Genos with the uprated sounds It is hard to get the touch right and  acoustic Instruments  can get a little droney or bassy hiding the sound of the strings. It is all down to eq and things like that. It will take me some time as It Is a new ball game with better speakers than the Genos ones.
These DXR's are In the premier league!! for a Genios ;D 8)
Keep In touch Marshall as we can swap ideas.


All the Best
John

Hi John,

I used the following 2 devices in testing hum / buzz elimination between Genos and powered speakers (I used a Zoom H4N recorder instead):

Rolls HE18 Buzz Off hum eliminator, $38 from Amazon (don't buy it, it was horrible in my test):
https://www.amazon.com/gp/product/B004E4LU0W/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1

Radial ProD2 stereo direct box, $150 from Amazon:
https://www.amazon.com/gp/product/B000B85FV0/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

Input side of these devices:
https://photos.app.goo.gl/sTqcqL2aKRdrNtZP2

Output side of these devices:
https://photos.app.goo.gl/40OUNkIySlTNrdb93

I used the following cables for the testing:
2 x Fender California Series Instrument cable (unbalanced 1/4 inch)
2 x Livewire Advantage balanced cable (balanced 1/4 inch)
2 x Whirlwind MK4 Series XLR microphone cable (balanced XLR)
https://photos.app.goo.gl/BZMMOSGG1uXLY7w03

I used a Zoom H4N recorder instead of a pair of powered speakers so I can load up the recorded MP3 files on Audacity to show the differences.

The master volume of Genos stayed at 12 o'clock position for all tests.  The recording level on the Zoom H4N recorder remained the same during the tests.  I used the Genos demo song "Orchestral" as testing source.

The main left output of Genos connects to a green Fender guitar cable, and the main right output connects to a red Fender guitar cable:
https://photos.app.goo.gl/aofPxLGCMfHkbYwy1

Scene 1:
Genos -> unbalanced 1/4 inch cables (Fender guitar cables) -> Zoom H4N / powered speakers
https://photos.app.goo.gl/066SaeP9ycQrJKXg1
The signal was very hot, loud, and clear, with some high frequency hissing noticeable through the monitoring headphones on the Zoom H4N.  However, the high pitched hissing is not noticed on actual recording.
The recorded MP3 file: 
https://drive.google.com/file/d/13Vq-JtGqw3RFOFkr0bQ-RbGUvp_m27pV/view?usp=sharing

Scene 2:
Genos -> unbalanced 1/4 inch cables -> Rolls Buzz eliminator -> balanced 1/4 inch cables -> Zoom H4N / powered speakers
https://photos.app.goo.gl/QVCaGt35vTE3B0D43
The cheap Rolls Buzz elminator actually introduced loud buzzes, same results with different sets of balanced cables - it is useless, and I will return it.  I did not order the Ebtech hum eliminator, which has balanced XLR outputs.

Scene 3:
Genos -> unbalanced 1/4 inch cables -> Radial ProD2 stereo direct box -> balanced XLR microphone cables -> Zoom H4N / powered speakers
https://photos.app.goo.gl/xpyyRFJ325k1tGqs2
The signal was very quiet, a tiny bit of high pitched hissing still noticeable through the monitoring headphones on the
Zoom H4N, but a lot quieter than scene 1.
The recorded MP3 file: 
https://drive.google.com/file/d/1-pzyAQNDiIcZBFBNm6vuOtSQmzzyGmO2/view?usp=sharing

Visual comparison of audio signals between Scene 3 and Scene 1:
Scene 3 on the left (with Radial ProD2 stereo direct box) and Scene1 on the right (Genos with good unbalanced cables only)
https://photos.app.goo.gl/2TWSpwhlXbhErFpK2

I could not hear any high pitched hissing on the two MP3 files.  However, during the recording sessions, through a pair of monitoring headphones I could hear the signals much cleaner through the Radial ProD2 stereo direct box.

I highly recommend the Radial ProD2 stereo direct box as a solution to minimize your speaker hums situation.  If you are satisfied with reduced volumes on your powered speakers, you can just stick to your current setup.  BTW, the audio quality US$25 Fender unbalanced 1/4 inch California Series Instrument cable is not bad at all.  I used 2 of these cables to record stereo tracks directly from Genos with good results.

I am not going to test Ebtech hum eliminator since I prefer the much more versatile Radial ProD2 stereo direct box (with additional individual thru, -15dB pad, and ground lift).

Thanks,
Paul

Scene 3 on the left (with Radial ProD2 stereo direct box) and Scene1 on the right (Genos with good unbalanced cables only)

I could not hear any high pitched hissing on the two MP3 files.  However, during the recording sessions, through a pair of monitoring headphones I could hear the signals much cleaner through the Radial ProD2 stereo direct box.

I highly recommend the Radial ProD2 stereo direct box as a solution to minimize your speaker hums situation.  If you are satisfied with reduced volumes on your powered speakers, you can just stick to your current setup.  BTW, the audio quality US$25 Fender unbalanced 1/4 inch California Series Instrument cable is not bad at all.  I used 2 of these cables to record stereo tracks directly from Genos with good results.

I am not going to test Ebtech hum eliminator since I prefer the much more versatile Radial ProD2 stereo direct box (with additional individual thru, -15dB pad, and ground lift).

Thanks,
Paul
Thanks Paul for confirming my recommendation the Radial Pro D2 is the one to complement the investment....A Note to "YAMAHA" ...you where noticeably late to the scene with balanced outputs on your high end synthesizers perhaps you will remember to correct this with Genos2 as this will so deserves to have "balanced outputs" next time ...all the best  :)
