I have experience the same predicament during the first few weeks after our T-112/IDR-48 came in. Instead of rebooting shutdown then power off both surface & rack, the rack must always be turned on first then the surface so it can connect properly. I guess that should be the sequence since the DSP engine is in the rack. Never had a problem since then.
Have to agree with kentlowt, it also happens to some yamaha, soundcraft, etc. digital consoles.
Our unit is working so fine now, i also had to carefully configure the TCP/IPs of network connections. IP conlficts can cause system errors.
audiolab - this was not a boot order or network problem - it was a mixrack hardware failure.
I have recieved my repaired IDr48 back from service (new DSP board) and found out that the likely reason it failed was because of a rogue washer floating around inside the MixRack! I actually feel some relief at this as it was an explainable mechanical short circuit. This is better than a mixrack DSP that can randomly fail at any time! Don’t have any idea how a washer could get in there -perhaps from manufacture? The unit has been transported in a sealed SKB case all it’s life and has always been transported upright. For a washer to get in it would have to be through a vent or the fan. Oh well - I’m just happy we are running again. Think I will always have a backup mixer plan now though.
Further to this thread - Is seems my IDR48 Mixrack failure could have been caused by a component failure in the main board power supply. I talked to the tech when my IDR was repaired and it appears that certain temperature/humidity conditions (mainly in the southern hemisphere) can cause this Mixrack main board failure to happen. I know that many IDR mixracks that had been sold in NZ (and possibly Australasia?) were recalled and modified to prevent this happening (back in December/January). It’s all been good for some months now so lets hope it stays that way!!

If I remember right- there was a service bulletin issued by A&H and that was something to do inside iDR in order to prevent failure in excess humidity environment. I can look for it if someone is interested.

there was a A&H sponsored “PCB” mod last February…as I understand it, your local A&H dealer/purveyor would/should have informed you of the mod (to the idr rack…) you might want to check this out with them…
Nothing really complicated for most service departments

You’re correct that this shouldn’t tax a suitably experienced audio service engineer, but please note that we’d be amiss not to point out that such work must only be carried out by an authorisedAllen&Heath service engineer; this is both to ensure any warranty isn’t adversely affected, and so that the system can be fully tested following any modification.
If you do need more info, and as RayS’s already suggested, please do get in touch with your dealer, or our distributor for your region.
