GL 3300 psu

Started by Chip Vaughan Mar 2. 0 Replies

I have an Allen&Heath GL3300 and was wondering about the psu. It has the older style 5 pin xlr input for the psu. Is there any way to mod it to except a different input. I have a couple of psu's…Continue

Channel dropout or jump to full gain tip for older GL series small/medium format desks

Starting last year, I began having intermittent channel drop out issues on my GL2200-32 desk. It was the type that could remedied by cranking the channel put up all the way to cause the bad…Continue

I agree with Greg, I use Deoxit D5 spray to clean the faders then move them up and down 10 to 15 times to displace surface contaminants. After that I use 1 drop of Deoxit Fader Lube and move the faders up and down once again for 10 or 15 times and your console should work well.

My son introduced me to it after he returned from working on a cruise ship. In that salt water enviroment he found that it not only worked well on console faders but also on XLR connecters up on the pool decks and it worked really well. I gave it a try on my Ramsa console and I have been using it ever since.

Cheers, Mike

Worn, oxidized fader pots can cause noise if the wipers aren't making good contact. If that's the cause, replace the pots. After that, first thing is to clean ribbon cable connections and reseat. Use Caig DeOxit on the connections. Maybe replace the ribbon all together. If the problem persists, it's time to remove the PCBs for the problematic channels and start looking for broken/cold solder joints. If that checks out ok, it's time to start looking at individual components. If that's not your bag, A&H may still have new PCBs for a reasonable price. I recently had to do some work on a GL4000 and had to replace a couple of the group channel PCBs as well as the PCBs for the meter bridge. It wasn't very expensive to do and the parts were still available.

I have a 40ch. GL4 which I spent $1,500 on with Creation Audio and it still has a couple of "phantom" issues with two or three channels flickering and making noise with no input. If anyone has a fix this issue or would like to have it for their very own, it has a case and two good PSU's. Lee@superiorsoundinc.com

I still have a GL2400 that I use for monitors all the time. It is a great little board for the small gigs.

@Chris, thanks for saying so. We are trying hard to make changes and make things better all the time. Let me know if you have any ideas of what you would like to see.

Hey Callum, same for myself I taught myself audio on a GL2400. One day will probably buy one to teach my son (if I ever stop touring).

So the new GLD series is iLive in reverse. I think A&H will sell a few.

Love the GL series. If I had to go back to analog, that would be my only preferred option!

I started out on the GL 2400, Brilliant console!

Great job to Pro Audio Space on the concept of having groups for key products.
