Calibrate it All!

Is it worth doing a specialty audio calibration in areas of a residence outside the dedicated theater? Absolutely! 

Getting the spectral balance, bass management, and time synchronization of audio systems tuned for each and every environment is a pretty simple and cost effective way to upgrade the sonic experience. You can get good dialog clarity, smooth bass, and a reasonably good spatial rendition with an hour or two spent in every space. You do need to have some digital EQ functionality in the system, and that is getting pretty easy these days. I am not talking about auto-EQ, which I contend still doesn’t work right (unfortunately). I mean some number of bands of EQ for each channel that you can adjust while monitoring an analyzer application running on a laptop. That function is available in a number of multichannel amps (Sonance, Ashly, Powersoft, to name a few), in a number of receivers and decoders, and of course, as stand-along EQ devices placed between the switcher/preamp, and the amplification stage. Even in environments that acoustically very live, the end result is well worth the time invested.

Here’s a grab bag of pictures of projects I tuned in the past month using EQ, time, and care. You’ll see a specialty “fun room” with Atmos immersive audio and 4K video, but also a kitchen with ceiling speakers, a large backyard with bollards, a few simple media rooms and a bedroom. In all cases, the clients clearly heard a vast improvement, stating that the dialog was clearer, the sound more dynamic, warmer, more engaging, and a number of other plain English adjectives. Bottom line is that all were happy with the results and with the invested dollars.

A very nice "Fun Room" with 4K UHD Video and Atmos Immersive sound!







A simple 5.1 channel TV room. Dialog and effects sound a lot better after calibration!





The kitchen: center of all home life. Music and broadcasts come alive after tuning the ceiling speakers!



The backyard sound system went from edgy to smooth in less than an hour!






Voice clarity and sonic envelopment are much better thanks to EQ and proper delay settings!







These small media rooms went from mid-fi to hi-fi thanks to calibration work!

What happened this time?! EQ With a Healthy Side of Hum.

What happened this time?! EQ With a Healthy Side of Hum. So I was on this job site the other day, with the classic set of challenges. The client had bought a high-end 2-channel system from the integrator: Wilson Duette speakers, Linn preamp, Moon/SimAudio power amplifier. After it was all up and running, the client complained there was "not enough bass". So, the integrator sold him a couple of JL Audio subwoofers and asked me to come along and make the whole thing work - setting crossovers, time-aligning the speakers, balancing levels, equalizing the response, and voicing. We used a trusty Ashly ne4400 DSP audio processor; it’s a pro-grade digital audio processor with EQ, crossover, delay, level - the works. When I got to the location, things were a far sight worse than just "not enough bass". The installation of the EQ hadn't gone quite right; they had no audio signal, but a *lot* of hum. Client was steamed. So in I dove. In cases like this, there...

THE GRIMANI FILES: Bringing Life to a Comatose Home Theater

This client was referred to us by the integrator, who completed this installation about 10 years ago. The room was a dedicated three-row home theater in an upscale neighborhood of Detroit. All the gear was state-of-the-art for its time - from the studio-grade speakers, to the professional HD video projection system. But the surround decoder finally gave up the ghost after several years of faithful service. The client heard that Dolby Atmos® was the latest thing, so he sourced a new processor. He expected it to be an automatic upgrade, but wasn’t aware that he also needed to add speakers for the Top and Wide locations. At any rate, it was time to install, configure, and tune the system for the new processor. I took the job and carved out two days - right before Christmas - for a quick jaunt from my temperate San Francisco Bay Area home to frigid Detroit. (Who doesn't like a little cold for the holidays?) While planning the trip, I found out that the system didn’t include any ...

Fun Room Details

In Deep Thank you for reading the high level article, now we will go into a detailed explanation of this project. This blog expands on the details from the " Home Theater Has Come Out of the Cave " article. The integration firm responsible for building this masterpiece is  Audio Images  of Tustin California. Our designs and engineering is only as good as the implementation and AudioImages came through on every detail. The Room Shell The physical issues that needed to be dealt with to accomplish these goals dictated a few design solutions: Sound Isolation The room had to be decoupled from the Great Room that is located directly above it. This prevents the sound leakage from disturbing the adults. Decoupling loosely means to build resilient wall and floor-ceiling structures with little to no connections to the house’s framing structures. The purpose is to limit every contact point that could mechanically transfer sound energy and interfere with daily use ...
