Axiom Home Page Forums General Discussion Technical Questions Channel balancing / trim settings

Here’s HK’s response…….


My question –

While in Dolby Digital, the + / - channel settings do not change. However, if I switch to any of the other surround options on the HK (logic 7, Neo, etc) and then pull up the OSD, the channels are all at the factory setting of 0. Can you explain this to me? Is this supposed to happen due to the different surround processing? Am I supposed to re-calibrate the speakers in all the different surround settings?

Response –

Good evening. When in a digital surround format it is possible that the level setting is allot lower due to the amount of data compression. The analog formats like Logic 7, DPL II …will have a higher input level which give you a setting from 0 and then depending on the level input from the source you are using you will be able to trim the level from 0 to prevent the input from being over loaded.

Channel reset simply returns all of the calibration levels for the receiver to 0 all over again.

I hope this helps.

I can't make heads or tails of it.

Well, that's allot clearer.

I kind of like the idea of having independent level settings for each speaker in each mode (if that is exactly what's happening)... I've never owned an HK receiver.

But it makes sense. Not only will your speakers be different distances away/reinforced by room placement (which will stay they same throughout program audio modes), but each mode will assign signals to the speakers differently (Neo6 Cinema sends more to the centre than Neo6 Music for instance).

Just got done playing with the channel adjustments again. Here’s what I had to do.

First off, I could not switch between the different modes without an input selected. Meaning, the damn thing will not let me change any settings but DD if just using the OSD without an input being routed through the receiver to the TV. When trying to do this, I could select the other surround modes, but after setting up the channels for the first mode selected and then going back out to the main audio set up screen and selecting a different mode then selecting the channel option, it would not bring up the menu to change each channel. Clear as mud??

So for a work around this, I selected the satellite input and then hit the OSD. I could then go into each different mode and set up each channel for all the different surround modes. Strange, but that’s the only way I could do it.

There is a remarkable improvement now when I’m watching the satellite and I switch back and forth between the different surround modes. All sound different, but it isn’t overpowering on one channel or the other anymore. Some modes seam to send sound to the speakers differently, but none are “louder” than the others now.

Now I just need to get a disk that will send pink noise to the sub so I can set that. I’m currently running back and forth to the sub and playing with its volume control, but that’ll get old real quick. We are watching the lord of the rings movies again with the new system. What’s up with these movies? They sure seam to have a hell of a LFE channel. More so than any of the other movies I’ve watched yet.

What disk should I buy to generate pink noise for the sub? Do any DVD’s have this, or do I have to buy a special disk?

Glad you kinda figured it out, Mike. I feel bad because I own an H/K but didn't offer more help. Sorry, but I've been in and out of the house over the past week.

It can be time consuming to properly set up (and confusing and frustrating), but once completed it offers a good level of control for each input.
