Keyboards and Amplifiers

Post by WakemanFan55 » Mon Sep 22, 2008 10:54 pm

Hey. its me again...
Now that i have a couple of synths, and 1 amp, how to fix that problem?
its kind of boring to change which synth im playing on all the time, so is there a small "mixing table" (dunno the right word for it) where i can plug all my keyboards in, and from there to 1 amplifier?

sorry. my english is just....well...bad, but oh well.

Regards.

Hi,

Yes, you need a mixer. So, if you have two synths you'll need at least 2 pairs of stereo inputs. Connect each synths left and right ouputs to the inputs on the mixer. Then connect your mixer outputs to your amp. A mixer will also have additional outputs for headphones.

Here is an example:

Of course mixers have different sizes and features depending on what you need.

Hi thanks for answers it really helped me.
I got 5 synths, is it just to look for a bigger mixer or is it any thing else that is important, since its going to hold that many synths.
GA? the one you linked to did hold up to 4 right? (4 is more than enough, i dont use my Casio that much)
i got a. (if that is to any help)
Moog Rogue
Korg 770
Roland Juno 60
Korg PE-1000
and a Casio CTK-900

Thanks.

Well... there are a number of ways to do it...

The Rogue and the 770 are mono (one channel) right? The rest are stereo (I believe the PE-1000 is stereo, and the CTK allows you to split out a stereo line from the headphone jack). That means you can set up your outputs like this:

(A) Mono output for all boards - one board/one channel. That means you'd need a mixer with five or more channels.

(B) Mono output for the mono boards and stereo outputs for the stereo boards. That means two mono channels and three stereo channels, for a total of eight channels.

(C) A combination of A and B.

The problem with A is that most mixers usually have two mono channels and then some stereo channels, meaning that you might be in a position where your mono inputs are going into either side of a stereo input, meaning one board will be all the way right and all the way left.

The good thing about B is that most affordable 8-channel mixers are set up with two mono and three stereo inputs.

Of course, since you'd be going into an amp, then you won't hear stereo anyway, so the point is moot. On the other hand, it's always a good idea to buy for the future, and if you get into recording, you'll probably want to be able to record your stereo boards in stereo. Also, there's a good chance that you'll run out of channels (with stereo boards, this can happen quickly). You might want to add another board, guitar or mic to the mix. So it's a good idea to buy a mixer with more channels than you need right now -- say, twelve instead of eight.

Thanks!
I got your point there.
I forgot to mention a polysix in here, but i suppose that is going in the stereo output.

Is it something like these im looking for?
