Plug-In Powered Mic Input -- Mono?

[gmcmurry]

I am using my Micro BR as a practice device with my trumpet.  The Plug-In Power mic input works great with both my Yamaha Silent Mute as well as the Yamaha MC7 Pickup.

I have been using this for quite a while on the road for quite practice where I play my horn along with MP3 silently into headphones.  Not too many people want to stay in a hotel room next to me if I don't..

My question is that both the Silent Mute and the MC7 Pickup are both single channel mono / monophonic devices.  When I plug them into the line input and engage the Plug-In Power I only get sound on the left channel. 

I have been thinking about cutting off the 1/8th inch mono jack on my devices and re-soldering on a stereo 1/8th inch so I can feed both left and right channels but I would guess there is a setting somewhere that will do the same thing.

Any ideas?

Will selecting one track work? Defaults to 2 on plugin power I think. Probably wont but the only thing that springs to mind.

A less drastic solution would be to buy a suitable mono-to-stereo adapter such as one of these:

These adapters will divide the mono signal equally between each channel of the stereo line input.

Whenever you record from a mono source, you should only record to a single track. When the line input is selected and you select a track for recording, it automatically arms a pair of tracks because the line input is stereo and it assumes you'll want to record in stereo. However, you can easily override this by pressing the track button a second time. When you do, the record light will go out on the adjacent track of the selected pair so that only the one track is armed for recording. In this mode, the signals from the left and right channels of the stereo line input are combined into a single mono signal.

You can use the above technique to record directly from your mono input source without an adapter. However, since the two input channels will be combined, and only one of those channels has a signal, you may find that you get a stronger signal if you use an adapter. On the other hand, you may find that you get perfectly acceptable results without an adapter, so you might as well try it before rushing out to buy an adapter.

I know it has taken me forever to get back to your quick responses.  Thanks for all your advice.

I had just left on a long trip when I made this post.  I was in the Czech Republic.  I looked everywhere for an adapter as suggested but never found one.

Now that I am home (Los Angeles area) I found one in about 10 minutes -- AND it works like a charm. 

No cutting off the cord now..
