Digital room correction, any recommendations?

I'd highly recommend acquiring software that lets you see the frequency response and reverberation times of your room. Then you can apply room treatments to deal with the areas which can be fixed.

As for digital room correction, I've tried Z Systems and Audyssey and most recently Trinnov. I use a dedicated Trinnov unit that does 4 channels (recently released). I auditioned it for some time in my system before decidig to go ahead with the purchase. It has proven efficacious and worthwhile and I am quite critical of things that alter timbral purity, resolution, etc. One of the nice things about the Trinnov is that it has a highly detailed interface that provides a tremendous amount of information as to the sound in your room and also the means to make fine adjustments over a variety of parameters. The downside is taking the time to understand what you are doing.

Hi Psag,

Before making a final determination, I'd read up on the different technological approach that Trinnov use.

They employ some very sophisticated modeling and mathematics to analyze the sound. Also, read up wherever you can on the Tact and Lyngdorf approaches and see what you find from other users and ex-users (of any of this gear).

I agree with Kal's comment above regarding the steps. I have the XTZ software and then tried Audyssey (as built into my Denon AVP-A1hdci) and auditioned a Multichannel version of the Trinnov Pro unit. Both units took a digital in; the Denon output an analog signal while the Trinnov passed the digital signal to my DAC (Boulder).

Hi,
I happen to be local to the US Trinnov rep (and partner in the company) and borrowed a unit from him. Curt is very helpful and knowledgeable. I picked up my ST2 Pro today and will run it through its paces this weekend and take notes. Seeing as no one has reviewed the Trinnov in depth I may write something up. What I like is that the unit shows both the frequency and time domain response and corrects for each separately (or you can make the corrections by creating your own target curves).

The Trinnov ST2 Pro (there will be a consumer version with RCA SPDIF and Toslink digital I/O and RCA analog I/O) can process 4 channels although there are 8 channels' worth of inputs, 4 XLR RCA and 4 AEX/EBU channels. I believe you can mix and match - I will be testing this with my Oppo player to see if I can get the LPCM left right stereo in via digital and the center and subwoofer in via analog (using XLR adapters since the Oppo outputs are RCA).

You can also biamp and use the output (4 channels) with the software based crossover.

Feel free to ask me more pointed questions. I almost went for the Accuphase DG38 earlier this year but feel that the Trinnov approach seem quite solid and innovative. For one, the Trinnov people seem to have made significant inroads in professional cinemas and on the professional level, which lends some credibility to their approach. The well known US home theater component company ADA also will be releasing their version of a RC unit based on Trinnov technology.
