Hi,

Last week, I was listening Yessongs with my HK990 Amp, and it sudenly died.
I turn it off/on and it gave me the following message:
FLASH CORRUPTED
UPDATE DSP FIRMWARE

It also gives me Error #005

It seems the problem is only in the Digital Section. I tried the Processor Bypass and it is Ok. I did not try the Analog Inputs.

I contacted USA, UK and Brazilian Support by e-mail, with no responses yet.

I think if I could get the Firmware, I could install it by myself. I can not send this 100lb amp Overseas.

I would like appreciatte if someone could contact HK directily.

Any help will be wellcome.

Thanks

Have tried calling HK support in Brazil? Response may be much quicker over the phone than via email.

Many surround receivers have a microprocessor reset code that restores the receiver to factory defaults. You might research to see if the 990 has one.

Any 2 ch integrated amps there with crossover setting for just the main speakers ? I (or is it WE ?) dont need the bass managment system as 99.9999 percent of subwoofers has this feature already. Just imagine the relief of your amp knowing that it no longer needs to provide juice for those low frequency that just gets eaten by the passive crossover.

While the idea of having room correction processing built into anintegrated 2-channel amp is indeed appealing, reading of the problems with the hk990 have me worried and thinking that maybe the technology is still abit too new.

My strategy was to buy an integrated amp with bass/treble controls AND with pre-out/main-in jacks. This way, once prices come down on eq devices, i can borrow a unit from a local dealer, insert it b/w pre and main amp to see if I like the changes it makes to how my system sounds. For now, basic tone controls give me some measure of control.

A sub crossover typically only has a low pass filter, and the crossover point should be set to the low frequency roll off of the speakers. Bass management on receivers have a low pass filter to roll off the sub and a high pass filter for the speakers, thus allowing the user to choose from multiple crossover points.

Wont you be able to do the same thing with only the high pass filter for the speakers, since the sub has a low pass filter already ?

Am i missing something here with bass management ?

What "high-pass filter for the speakers" are you talking about?

It wasn't a showstopper for me, as I have no plans to add a subwoofer. Not as pretty, but low-pass crossover on the sub could be used (but, this deviates from the OP). The Onkyo does a lot of things right though, and is quite a good receiver for $260 (current Amazon price).

The Yamaha R-S700 is designed as a 2-channel 'audio' amp. It includes a subwoofer out, which I assume is low-passed. I am not sure if it is configurable to high-pass the mains, but it appears so.

They're not going to get much cheaper than a MiniDSP is today.

But no xover to a sub(s) which was the point of the thread.

The market must not be there, otherwise manufacturers be all over it per the demand.

I been keeping an eye on such 2.1 receivers/pre-amp(with reasonable pricing last few years and all been mention above.

Ending up getting a Essex sub(maker for REL, its got similar input design).
Also using the NHT Controller in stereo mode, works great also cheaper then 2-channel pre-amp.

How does the HK 990 compare to the Marantz PM8004 in terms of sound quality? Someone recommended getting a used Lexicon RV-5 or RV-8...how would these compare to HK 990 or Marantz PM8004? Thanks!

Almost everything you mentioned is either changes to DSP software that is already there, or functions that are packaged up in multiples on chips, and have very low incremental costs.

The only things that are *real* are the extra power amps, and they have very low incremental cost. Leaving them out in some sense costs money because it vastly decreases the market and the perceived value of the product when they are not there.
