ADA PTM 1645 16-Channel Multi-Zone (8 Zone) Power Amplifier
The PTM-1645 is the pride of ADA. Also known as the “work horse” when it comes to multi-zone sound. While other sixteen channel power amplifiers exist in the industry, none of them come close to the PTM-1645 with respect to performance, size and value.
First and foremost, the PTM-1645 sounds amazing and is one of the main reasons ADA sits atop of the industry when it comes to multi-zone sound. Able to drive eight independent zones, the “work-horse” is also stable down to 2 Ohms – making it capable of driving four pair of 8 Ohm speakers per zone.
In addition, when adding a pair of speakers to a zone (2 pair of 8 Ohm speakers), instead of sharing power between the two pairs, the PTM-1645 nearly doubles it’s output. The PTM-1645 also occupies only two rack spaces (3.5 inches in height) and because it is force-air cooled from side to side, it is specifically designed to be installed in very tightly packed racks. As for value, the PTM-1645 is built like a tank and designed to outlast other electronics out there.

Hello please pardon my spelling , it is not my native language. I found your article on Technorati “ADA PTM 1645 16-Channel Multi-Zone (8 Zone) Power Amplifier | Multi Zone Amplifier” was more or less close to what I was researching for, but after studing through your story I still was not able find open solution to my problem and this is driving me nuts. I love your website and think it is absolutely helpful but I think you could make it even better if you fine-tune your internal website search to make it easier for visitors to locate required information within your website. You can accomplish this by installing WordPress addon… As far as I can remember plugin is called enhanced wordpress search it has a lot of valuable options like search excerpts, search comments.
