Bought a cheap dual mono to mono y-adaptor in Radio Shack today. I didn't have time to compare the sound to a one cable setup, but I did validate that now the mic comes through just fine!

As you suggest Gary, the other adapter I used must have been wired differently!

New Compact to be delivered on Saturday.

Sure hope everything works like you want. Bose is great about their service and will always help when needed. I have never found a reason to make a change from my Bose setup. The first Bose I had was the L1 which was awesome. When the smaller and lighter Compacts arrived I got two the first day. I ended up using only one of the Compacts and sold one. I never play for more than about 150 people and most of my gigs are under 50 people so a single Bose works out just fine. Good luck and keep us posted.

Graham, glad I was able to help.

First Assembly Church on the Road . Nice group of 23 in a semi-circle, so I just used one extension. You can see the cheap Y-Adapter from Radio Shack connected into the Bose.

Gotta love the invisible countryman mic.

Lookin' good there!

Graham what a great pic of you & the PA900/Bose!!

Thanx for sharing

Lookin good, mon!

To each his own, but I would place the Bose three feet back and off to the side a little. Just saying.

Bernie has a point about the position of the Bose but you need to keep it away from the wall or the Bass becomes really loud and overbearing.

That said, I have played hundreds of gigs with the Bose right next to my keyboard. Sometimes there isn't enough room to put it 3 or 4 feet behind me.

I just took a look at that adapter you plugged into the Bose 1/4-inch input. That's a stereo headset adapter and not intended for what you are hoping to achieve. Essentially, it parallels a pair of TRS plugs and causes lots of problems.

Now, I do not have a schematic diagram of the Korg outputs, however, I'm going to assume that they are similar to the Yamaha outputs. If this is the case, when you are plugged into the mono output of the keyboard, a leaf-switch is enabled on the quarter inch output plug that combines both the right and left channels, thereby providing you with a clean, mono out directly from the keyboard. What you have done is taken a standard 1/4-inch phono output from each side of the keyboard, and plugged it into two TRS plugs that are wired together. Yes, you will get output, however, you will also get an impedance mismatch, which is not a good thing.

The solution is quite simple, though. There are three inputs on the Bose L1 Compact. Purchase (or make) a pair of 1/4-inch phono to RCA male plugs, and input your keyboard into the RCA plugs on the Bose. This provides a stereo channel input to the Bose coming directly from both channels of the keyboard. The output, of course, from the Bose, will be in mono, but it will sound very full and robust.

Hope this helps,

Gary
