Hi,With my KN 7000 I would like to install a amplified sub to sub out 1. so I will have a better base?
Because I am going to a place up north and I will play in a small area ,and I will not bring my amps,speakers etc...
If I can plug the amplified sub ,what will be the settings in my KN7000 ( I read the manual but I have a hard time to understand)
Thanks in advance

Most Subs have a crossover network which cuts the highs so just plugging into the R/L output will do the job. If your sub does not have a crossover go to Menu – Sound --- Separate sound settings. Here is where you will make your choice.

Years ago I used the Sub setting, one for drums (Right) and one for bass (Left) Stereo. All went well until I used a friend’s midi file, the subs were cancelled , I had no drum or bass sound just my right and left hand. A n d a floor of dancers that were staring.

I Hope this helps, John C.

Thanks John for your reply ,My sub have a crossover,so thats mean I will use 2 jacks from the main out to one RCA plug to my sub
I will wait your answer before I proceed
Thanks

If you're only going to a small hall, why not use one of the Reverb settings?

You will find these by pressing:-

PROGRAM MENUS (on the right of KN under the Red Record button)
This will take you to the first of 2 pages of suggested reverb settings for various sized venus.

I sometimes play in a Community Hall and find the setting 'Large Hall-1' (on page 2) is more than adequate for the job, but of course, it does depend on the hall itself e.g whether it has wood flooring or a carpet.

Try it out at home - you will be surprised at the differences.

Good luck!

There is no need to use a stereo (Two wires, left and right) for a sub. One wire in the Left/Right mono output is all you need.

Audrey Turner has a good idea about working with your reverb settings they do improve the sound. To much reverb makes the sound very thin. The right about gives a fuller sound to your set up. (Just my opinion)

John C.

Thew important thing is your source...If you are coming from the keyboard via the mono output..there is no problem with a single input to the powered sub....but if you are coming from stereo outs of the keyboard..you should combine left/right to the single input of the sub..via a Y cord or change the output to mono from the keyboard...

The reason you need to have left and right combined to the mono input of the sub...The bass and bass drum may be panned hard left or right..this will prevent the signal to the sub that has only a left or right signal to the input..

I understand that the Kn7000 has a mono output R/L -- which includes both sides of the stereo outputs.
That is all that the sub needs, it is a mono unit, a single wire.

Please correct me if I am wrong.
John C.

You are correct..

Hi, The KN7000 as a main output left and right So I install 2 mono jacks Y to one input RCA and it work very nice The sub made a big different.And I ajust the reverb as Audry told me
Thanks to all of you ,very kind

You're welcome!

I feel it would be helpful to understand playing in stereo as applied to keyboards.

Two different signals amplified separately. Panning or degree of panning refers to how the instrument is has been set up. A trumpet for instance may be sounding from the left speaker and not the right, or it may be 40% on the right and 60% on the left or they 50% to each side. Normally the purpose for panning in a stereo mode is to capture the same sound you would hear if you were standing in front of the band. Stereo will make the sound more realistic. If you were standing on the left side of the speakers you would hear what you would hear if you were standing on the left side of the band. Stereo is sometimes used for a desire effect; it can give an effect of an instrument traveling from one speaker to the other, a moving effect.

Having said all that what happens if I do not wish to play in stereo or if I do not have a stereo amplifier as in the Bose compact amplifier? For this reason most keyboards have an R/L output. This output combines both sides of the stereo into one output, right and left sides are combined they are one.

When you use a Y wire to connect right and left to a (mono) amplified sub you are doing what the manufacturer has already done with their mono (R/L) output.

John C.

Right John
It is summed(L&R) to mono.

Thank you for your explanation of 'stereo' sound John C.

This subject came up at our Club recently as someone had seen the new Bose being used at the local Organ Club but he couldn't explain how it worked without speakers. Although I had some idea, as a few years ago I used 'amplified speakers' which were good but I couldn't explain how they worked, let alone the Bose, so I will pass on your detailed explanation to our members at the next meeting.

Audrey

It’s always best to use the mono output provided by the manufacture to connect to a mono sound system, as if you use a Y lead you sometimes get phase anomaly’s when playing Stereo sampled sounds. (The manufactures mono outputs designed to prevent this from happening)

Bill

So thats mean I will have to choose between the main out left or right Because on the KN7000 there is no mono R/L+
like the others keyboards
ON the KN7000
Main out
L and R

Wrong, Sorry
On the back of the keyboard you will find R and L and inbetween them you will find MONO -- meaning one combining both sides R and L. (R and Mono are the same impute)

John C.

Well your right John
KN7000 =main out R and L
But the R is R/mono
Thats mean that I will plug only one jack in the output R/mono and connect to the input sub?
Thanks John

One jack in the output that is second from the left marked MONO.

thanks Bernie everything is working good
