  • setting up gain structure with Audyssey based AVRs and pro amps

    What's considered the best practice for setting up gain structure ?

    I understand that the ideal is to have the AVR and the amp to clip at the same time. What I am not clear about though is how to get there.

    My AVR is Denon 4311 and I use inuke3000DSP to power SS-18.2.
    I have the following controls:
    1. level trim control on the AVR
    2. global gain control on the amp
    3. level trim control on the amp.

    Here's what I do:
    1. Set sub level on the AVR to 0db.
    2. disconnect the subs, run a test signal and adjust volume trim and/or gain controls on the amp until the level LEDs get into the "red" territory.

    This in theory should satisfy the requirements. One thing that throws me off is whenever I run Audyssey after that it finds that the sub level is hot and i have to trim id down from whatever settings I thought were optimal.

    can you give me any pointers on how to do it properly? Also, when should I use the global gain on the amp? Should I leave it at 0 if I am able to drive the amp into clipping without it (even if i have to leave the trim level wide open to do it)?

    thank you

    zheka - this is probably the best thread online for understanding gain structure and best practices. Very informative and often referenced.

      Thank you. I am familiar with this one, it has a wealth of information but I personally had a difficult time extracting subwoofer specific bits and at the end not at all sure I got it right. Besides it does not address the issue with Audyssey calibration and sub volume level.
      I hoped that users here who've done it countless times may give me some easy to follow instructions. If not, I can probably ask Wayne on HTS forum.

      thanks again
