HEAR technologies mixer problem

I've had it for 3 years. Now it stops working every 10 minutes while the power supply is OK. I phoned 2 distributors and mailed Hear technologies 2 times. Got no answers. Session with 5 studio musicians failed. Such an important piece of gear but you can not rely on it nor on it's support.

Don't read any further: support is great if you know the right guy and tornados stay away.


I did the mod and it is working now for more than a year!! Thanx

1- Remove the top of the unit. You should position the hub with the front faceplate towards you.
2- Locate the attachment “hub jumper” and note a PURPLE wire that goes from the power supply over to a trace
on the main board.
3- Look at attachment “R20 Connection”. This is on the supply, just in front of the RED wire coming f the 8-pin
connector. R20 is brown in color, with the body of the resistor to the LEFT, and a loop of wire going back into the
supply board on the RIGHT.
4- Tack-solder a 3” or so wire to the top of the wire loop on R20. DO NOT SHORT THIS TO ANY OTHER
COMPONENTS!!! The caps and small inductor near the resistor can be gently pushed a bit out of the way.
5- See attachment “main bd conn”. With an exacto knife or similar tool, scrape back about 1?2 “ of conformal
coating on the trace shown. NOTE THIS TRACE IS DIRECTLY SHORTED TO THE RED WIRE COMING FROM THE
MULTIPIN CONNECTOR. You can use a meter to ohm out this point just to make sure.
6- Tack-solder the other end of the wire to the trace. Make sure it does not short to the trace to the left of it.
7- Plug up the AC cord, STAY AWAY FROM THE SUPPLY and apply power. The clock LED should come on green with
the unit in analog mode.
8- Unplug from the wall, replace the top.
9- Have a cup of coffee or a beer........job well done!

are the ethernet plugs snug on both ends?

seeing lights on the satellites and the hub?

outputs on hub working fine?

had issues with my satellites going down and it was the teeth of the ethernet cables not making a connection.

It's a wise investment to have a second Hub on hand. The price of the system pretty much warrants it.
Sorry for your predicament. It really screws up a session to have drop outs. Otherwise, the mixers are very helpful for keeping players happy with what they are hearing.

@Reanimatorstudio -

Sorry to hear about your problems, but I gotta disagree - I've had a Hearback system running for 4 years or more. I did have a few problems with the power supply early on, and the customer support from Hearback was great. I called them up, described the issue, they recognized it right away and sent me out a replacement power supply which i was able to swap in in about 10 minutes - problem solved.

Haven't had an issue with it since. Works great, sounds great, totally reliable - that's my experience.

Email me, I will get them in touch with you.

I have found them to have exceptional support to say the least. Everyone I know who uses these systems loves them.

I will do that, thanks in advance!

The hub was even not working on my bench with only one mixer connected. Even without anything connected.
I was inspecting and measuring the things I could do without the schematics and didn't find anything wrong. Than I puched one spot on the pcb to detect soldering problems, the led "clock" went immediately from red to green.
Now it is working for 3 hours. So now I have to find the bad contact. could be pretty impossible on a digital smd unit without schematics.

Keep you informed

My experience does not invalidate yours, but I have had really good luck with the system, especially considering the price.

If you think you might have soldering issues on a board, you can reflow the solder using a heat gun. I fixed my friend's laptop this way. It sounds hokey, but it works. No need for schematics.

I built my own analog split system with standard balance TRS connections 12 years and zero issues. Uses a standard mixer so each channels has EQ / sends etc.

As an update, I was just reminded by the HEAR rep that the tornadoes devastated their area in Alabama USA and they were offline for a number of days. This could be part of the issue with your communication, their whole operation got turned upside down from weather.

I will hit you by PM with the info I got.

I had the same issues. I decided to switch over to an Aviom system, much better in my opinion.

Thanx to Gearslutz esp.War, Max from Hear technologies got in contact with me and gave me a decent answer.
It is probably some minor problem with a pcb trace. Something that can be fixed in 5 minutes. I did the small mod he suggested (one extra wire). Let's hope it will solve the problem.

Seems Hear Technologies has got a serious support after all if the tornados don't pass by. Let's hope all went well there.

Hey Reanimatorstudio, could you tell me what the mod is ? I have 2 hubs en 6 satellites. I had my hubs (after they both went down in 10 days) repaired with the distributor in the Netherlands. Today during session I experienced dropouts. Not long. The dropouts appeared after working for 3 hours without any troubles. Suddenly they were there.

Or maybe you, or somebody else, can point me in the right direction for good service.

Thanks

Red, Green on Rocky Road

We've had a Hearback for a couple of years and it ran fine. Until this morning. As I powered up the SRS for church service, the clock bus indicator light came on red, and stayed red. I could get it to change to green for a few seconds by playing with some knobs, but that's it.

After reading through this thread, my question is: is this a similar problem to what you have experienced and does this MOD fix this particular problem?

Thanks!
