Original manual for boss rc 3 looper pedal - Boss Music

What is a Boss RC300?

Request directly from manufacturer

I would suggest cleaning the input jack, and if that doesn't fix it, replacing the jack.

1. Make sure that you have the correct power supply plugged in.
2. If you are using the BOSS power supply, it could be defective. Measure the voltage it is producing and make sure it is correct.
3. If the voltage is correct, then the problem is inside the unit, and it will need servicing.

You can make a backup on your pc and load back Default settings or restore to default settings. Normally you should have I quote ' with up to 49 minutes of mono recording time (or 24 minutes in stereo), the RC-50 can function as a song recorder as well as a looper'

I have the RC300 which has 3 hrs recording time. But when i reach the limit. I make a backup and load back in a initial default setup which I have downloaded somewhere. But you can also restore to default from the unit itself. Hope this helps

Most PROBABLE is the output jack either has been broken (common due to mishandling and accidents with cables such as stepping on the plug while plugged into the pedal) or the soldering of the jack in the pedal has broken loose. Less common is a circuit board crack in the vicinity of the jack. Open pedal and inspect for the above suggestions.

CHeck the voltage out of the adapter. It should be around 9 to 11 volts. If it is not, it is possible that the OC3 has reversed polarity AND a protector that put a short on an incorrect supply. If so, it could have damaged the RC50 adapter. If the RC50 adapter is putting out correct voltage, then I suspect the inout connector on the RC50 may be damaged or not quite seated. Visually inspect the connector first.

I have this, its a lovely looper when it works. what I think is the problem is that you need to empty the trash. If on a mac just go to finder and press empty trash while the unit is attached to the computer. If using a pc then follow the same procedure to empty the waste bin, as its called on a pc. Hope this helps!

Ok, solved this problem by visiting roland U.S. site as the help offered in this country is useless. The instructions given by email would not have worked even after the update was installed. Luckily, there are instructions that come with the download. If you have same problem as me go to http://www.rolandus.com/products/productdetails.php?ProductId=772&tab=downloads&skip=true

and update the opperating system on the RC-50 to RC-50 System Update Version 1.01.

Then hold loop sync and phrase 2 button (think it was phrase 2) to change it to sound priority mode. Then it will play back correctly what you recorded on the first loop, rather than missing the first beat.

Am v.happy I have found this, as after much searching I can't find any other loopers out there that offer 3 seperate loop tracks and the ability to switch between them effectively. Plus, it's a very convenient size, better than a load of rackmounted stuff to haul around.

However.....

Another problem..

When hitting the reverse switch ( I assigned both external footswitch and the onboard Tempo pedal to reverse) the change is not instanteaneous. There is a second or so delay before it plays in reverse. Not a problem for most, I suppose, but I have a piece that switches rythmicaly between playing forward and reverse which means hitting a pedal in time and reverse/forwards changing immediately. I think they could do with another software update to solve this. Now I have to keep room in my enormous pedal board for the old rc-20, as that does the reverse as it should - when you hit the flippin switch!
