Power supply polarity


Most of the time these things will have the negative in the middle of the socket and positive on the outside. I have found this true on most musical equipment but, other electronics will usually have the opposite. If it says 2000 mA, it has to have at least that much current to work properly, more is ok, less is not. Voltage must be the same to avoid damage. FIRST, I would definitely check the power supply with a test meter to be sure it is dead. The socket has a switch mechanism to turn on the battery when it is unplugged which could be stuck. If it were mine, I would take it back where I bought it and let them deal with it.

Does anybody know how to fix built-in microphones on rolland BR-600. When I attempt to record, the only sound that gets recorded is noice (hissing sound), and that only after cranking rec volume and mic...


Most of these have a SETTING in the menus that selects the source from different mics and/or line inputs. If the setting is to the line input instead of mic, and no audio is connected to the line input it will act like you described.

1) how to make my amp record....because its not working when i try... 2) do i have to a cord in line 1 and 2??? 3) do i have to plug in the cord in :.....line in or line out??????


You will use microphone with balanced XLR connector into the XLR mic input. Note, the ALpha does NOT have phantom power so you cannot use condenser mics.

A guitar can be plugged into the hi-z instrument 1/4 inch jack on the left front of the unit.

To use the line 1/4 inch inputs you will use BALANCED TRS 1/4 inch cables from your source.for these channels. The level on these needs to be line level.

The line outs are for sending audio out to an amp. There appears to be RCA outputs you can use as well.

I am not sure what you mean by making your "amp record"... An amp PLAYS the audio, usually into a speaker.

If you are trying to play a guitar through your amp AND record, then you will connect your guitar to the Alpha, the amp input will have a cable from say Line 1 OUTPUT and when recording wou will have the echo feature on so your guitar is passed through to the amp.

Maybe stupid question....is it possible to record 8 separate mono tracks on this thing? I cannot seem to select only track 5, 6, 7, or 8. When I try to record onto 5, for example, it is impossible to not...


I believe you have to adjust the levels DURING the bounce operation... I don't think you can do that after.

I would consider using a computer based editing program to handle more than 4 tracks...

No power to line 6 fbv express. Tried 4 different rj-45 cables. Using brand new spider IV as source.Tried recalibration procedure as recommended by line 6. Suspect main circuit board kaput


Is it still under warranty?

If so take it to your local Line 6 service center. http://line6.com/service_centers/

Before doing any of this you may want to try another Line 6 amp. Could be a problem with the amp itself.

I don't know....


Hi,

As you know, when you plug in your headphones, the amplifier cuts the sound to the external speaker, routing the signal through your headphones instead.

When you accidentally pulled the headphone plug from the jack, it apparently damaged the jack, which has the relay attached that routes the sound to your headphones.

Replace the jack, and everything may be OK. I say may be, because the jack is attached to a circuit board in these line 6 ampllifiers, and if you have damaged the circuit board, you will have to send it to line 6 to be repaired.

The downside is if it is not under warranty, it is an out of pocket expense, and Line 6 will not even give an approximation on how much a fix will cost. I have gone through it with Line 6 in the past, so I am very aware of the procedure. It is also a limited warranty, and they may not cover this particular damage.

However, if you are straight with them and they feel obliging, they may fix it under the warranty, if it is still active on your amp.

I had a spider 2 x 12, which was switching between amp models by itself, and they told me that because it was not under warranty, that I might want to consider NOT sending it to them, and just buying another amp. I didn't like that advice, because they seemed as though they didn't care about retaining my business.

Now, something to consider is taking it to a reputable amp repair shop (preferably one that is Line 6 authorized), and see what they can do. Maybe your clip is just bent, not allowing it to spring back from the contact switch that cuts off the main speaker. It could be a very inexpensive fix, but you need to have a shop actually take a look at it up close and personal.

Good luck. I, for the most part, enjoy Line 6 products, and their excellent distortions. Just remember, their amps tend to have a LOT of problems. You can find sites that list many many dissatisfied Line 6 amp owners. All that electronics (on board effects, soft buttons and switches, etc.,) make them vulnerable.
Now I mainly use my old reliable Marshall 1/2 stack with my Line 6 pod, as well as quite a few other pedals.

You would be amazed by the fact that you can still get pretty good money for a broken line 6 amp, maybe get something with less bells and whistles to break, and go with off-board effects pedals and processors.

Please excuse me for adding my own opinions, I am quite well versed in this type of advice having grown up in a luthier / guitar shop and have been playing for 38 years.

Good luck with everything, and if all goes right, adn it is just bent, it may cost you as little as a few dollars to fix. I'll keep my fingers crossed for you.

Thank you for using FixYa.

How do i recod on the ctk-900 casio?


Try running a line out from your keyboard to the line input on your mac. Go into system preferences, select sound, click the input bar in the upper right corner, select line in/Audio line-in port, then adjust your input volume. You should then be able to record from your keyboard. If this doesn't help you, please let me know. I'm a recording engineer that uses a MacBook for all my multi-track recording projects. Thanks & good luck. Mark
