MMP2 seems to have no voltage selector. Manual states power as 230, 240, 110v. I am reluctant to plug my US 110v unit into UK 230v mains. Would appreciate any info?

Check the manual..It's on the Roland site

In that unit , it's most likely an auto-switching power supply ie; universal 105 - 230 volts AC 50-60 hz

1 Answer

I have a roland keyboard mixing amplifier, KC-550. With an ipod plugged in, its only playing one channel, regardless of which channel I plug into, and the keyboard is also not sounding full. Not sure if...

The KC-550 is a MONAURAL amp and since the Ipod emits STEREO you have to use a special cable to MIX both the left and right from the Ipod into a single, monaural signal.

You can MAKE a cheapy mixer that will serve your purpose by using a series resistor, say 1K from each of the two Ipod output channels to go to the single mono input to the KC-550.

I would build it this way: Find an old IPOD cable or any 1/8 inch stereo cable and seperate the two wires and the shield. In a 1/4 inch plug, connect the shield from the Ipod cable to the shield (barrel sleeve) of the 1/4 inch plug. Connect one lead of each of TWO 1K resistors to the TIP connection of the 1/4 inch plug. Connect each of the two signal leads from the Ipod to the two remaining floating resistor leads. Insulate the splices.

DON'T forget to put the shell for the 1/4 inch plug over the cable before connecting the cable to the 1/4 inch jack. All parts should be readily available at Radio Shack.

I don't know that I have ever seen a suitable ready made mixer cable for this function.

Echo into mixer

I think the Echo's output goes into the mixer's input.You should be using one's output into other's input...that's how things work.If you r talking about both the system's input then they won't work with each other. Other thing is that if it's mono then there r cable available for the use which transfers mono to stereo input and vice-versa.

Roland AC90 crackles when using a slide.

It is because the AC-90 is not grounded. If you look at the power cable, there is just + and -, no ground/earth. This is because ground is not usually needed when using acoustic guitars/ mikes. If you use an electric guitar, or a slide, there will be problem. I have a AC60, that does go to ground. No hum. AC90=hum. Can probably be fixed by attaching new power cable and soldering earth to the chassis, like on the ac60.

Hi rockbert

Yes you can do this. the only drama you may have is at high levels where one amp may begin to clip and distort before the other. If you are trying to run a stereo setup, you could counter this to some degree by adjusting the bigger amps gain down to the same level as the smaller amp if needed, giving you control over the "stereo balance".

I am more than happy to answer any other questions you may have about it, just give me a hoy :) If you are still unsure, or have problems, then before you give a rating for this advice, please get back to me and we can try some more things.
Thanks for using FixYa, If you consider the advice I have given you as sound, a FixYa rating is a great reward for my efforts to help you. Cheers.
