Yesterday a guy come me from Atlanta to “see” my new installation.  I kind of explained that I am not in “demo mode” now but he still came to “see it”. I have no idea what he wanted to “see” and I was kind of obligated to play something to him. I had only one channel, but still not properly finally tined and not aligned. When I listen it I know what I want to her and I can make mental corrections and extrapolations as I know what is not done yet. He of course is not able to do it, so he has no ability to understand what I was trying to show off with the sound.

Anyhow, the Macondo in my view did not sound properly at all. We were listening just left channel sonly (only one midbass is connected), I played some oldies from 20 and 30s. He looked like he liked it – I have no idea what he was listening... It is not the point. The point is that in the end of the listening he asked about the Injection Channel and I decided to demonstrate it’s effectiveness. So, I did what I usually do – let to listen and then to plug in and out the Injection Channel.  It is interesting that I was forced to crank the Injection Channel up to -4dB in order the Atlanta guy to hear any difference.  What he did not know was that last weekend a friend of my stopped by to help me to put the Injection Channel above the Macondo… in absolutely random position. There was no alignment of Injection Channel’s tweeter to the Macondo’s tweeter done. So, the Injection Channel at -4dB was not as effective as it was in aligned position at -12dB. When the Atlanta left I give some listening and tuning to Injection Channel and I concluded that if the Injection Channel is not properly setup then it MUST NOT BE USED.

So, as ridicules as Injection Channel is , the Injection Channel is VERY powerful tool ONLY if it properly setup and properly used, otherwise it is just a waste. I know that are some folk out there who are trying to implement Injection Channels for themselves, make a mental note for yourself: if there is a super premise time aliment and frequency/amplitude dialing in then the Injection idea will not work.
