Markbass Mini CMD 121P LM3 Problem

[moncur]

[color=#000000][font=verdana, geneva, lucida,]Hi, wondering if anybody has had the same experience as myself with the Markbass Mini CMD 121P LM3 Combo.[/font][/color]

[color=#000000][font=verdana, geneva, lucida,]On Friday evening I went to use the amplifier. However, there seems to be a problem with volume coming from the speaker. I plugged a cable into the Line Out socket, and it does provide a signal to a mixing desk and works fine through a house PA. After maybe 30 minutes, the speaker suddenly comes to life for all of a few minutes, and then cuts out again. I have tried the bass amp again yesterday & today, producing the same results.[/font][/color]

[color=#000000][font=verdana, geneva, lucida,]Normally I just run the amp on its own for small pubs and clubs. If it is being used for anything bigger, I use the Line Out. It has never really been played at a loud volume, so I am a bit miffed if I have blown the speaker.[/font][/color]

[color=#000000][font=verdana, geneva, lucida,]If anybody could shed some light on this issue I would be very grateful. Thanks.[/font][/color]

Does the sound just cut out on the speaker but still provide signal to the mixing desk?

I suspect it's more likely to be the connection between the amp & speaker. Check the connection at both ends. I once had a similar thing with a cab and the cable had come away at the speaker end & just needed re attaching.

It's really easy to check the internal speaker wiring.

Remove the baffle screw, lie the cab on its back, remove the speaker and you can see all the connecting lugs and see if it's any those causing a problem.

If you bought it new & you haven't abused the combo, get in touch with where you bought it & ask them to fix it (for free of course). Do this before you start opening things up yourself.

Good shout. Opening up a cab or head can void a warranty. UK MB warranty is 2 years (although I'm not sure if this is transferable to a 2nd owner).

Initial repair would lie with the retailer but if they are unhelpful then the UK distributor are brilliant on warranty stuff. I can put you in touch with them if it is a warranty issue and the retailer isn't a lot of use
