I have two units synced via midi cables and coaxial in and out.
I can see meter movement of tracks recorded on unit #2, but I see no meter movement of tracks recorded on unit #1. I also hear no output. I have the monitor outs (7 & 8) routed to a Mackie Big Knob's DAW Mix yet I see no meter signal on the Big Knob's input meter. This setup has worked before many times. It's been a while since I fired this up. I also notice both units show that the batteries need replacement. Is this the cause?

Any help will be appreciated, thanks.

Unlikely, but change the batteries anyway.

Lack of meter deflection/track playback can be a classic symptom of capacitor failure.

Crackling during playback can be an early warning of cap failure If youíre handy with a solder iron, you can do the recap yourself.

Thanks dkfackler,

I was able to get playback after doing a re-load of the current project. But yes, I have crackling during playback, so I believe I have the cap issue.

I don't think I could do the recap myself. I have other 2480's, so at this point, I'll likely use the best one.

I have three -3 cards in a unit with crackle, I'll likely move them to the best machine I have.

As you have two VS linked, check that "COAXIAL IN" is on in VS #1 ( Master VS )
under "UTILITY" --> "PROJECT PARAMETER".

If not "on" there will be "snap, crackle and pop" when you play or record ....

If you un-link your VS's and play them one by one and still have crackles,
then there's probably the capacitors


Cheers !

I went through all the internal settings (like coaxial in), several times, to make sure I had it correct.

Needing to reload a song to get playback can be symptomatic of failing caps as well. That was the case with one of mine. Recap fixed all.

I agree.
Did you do the recap yourself?

Yes. Itís not difficult. IIRC, there are 48 100uf6v electrolytics to replace. I used 100uf16v radial lead caps; cutting the leads and bending to 90-deg to solder onto the original PCB pads. Do one at a time and go slowly. It took a couple hours. The main board does not have to come out. I had a list of which caps(by number) on the main board to replace. Itís in the 2480 Service Notes.

Does that mean there's other caps on the main board that don't need to be replaced ??
Or is 48 the total number of caps ?
( Asking for a friend )

Cheers !

IIRC, there are a few others(three 220uf, maybe others), but I replaced only the 100uf6v values, based on the experiences of other Planeteers.

A Tip: you will see a cap removal process in which pliers are used to twist the old caps from their solder pads. I donít recommend this as the PCB pads are fragile. Unsoldering, although much slower, is safer.

GEEZUS H. K.REIST!!!

I absolutely agree 1000%. ESPECIALLY being subjected to 20 (or so) years of use.

You might cough on these PCB's and risk snapping them accidentally.

Ok, THAT's actually a bit of an extreme statement; but you get my drift, correct???

I'm having the same problem but I'm not too sure if I myself would try to do this replacement. I may turn my 2480 into a paperweight, is there anyone that you may recommend to do the work? I'm willing to pay for the service. Thanks.

I imagine a local electronics repair shop could do this.

PM if you like the list of caps to swap. Each one has a unique number on the board.
