Teac A-L700P idea
« on: 13 Aug 2005, 06:18 pm »
Is it possible to bridge the two channels on each board of the teac together (like what's done on the Bel Canto eVo2) for more power?

Essentially, it would make two true monoblocks.

That'd give the teac much more headroom, but it'd need something powerful enough to supply it right?

This queston goes out to Vinnie or anyone who understands Teac's implmentation of Tripath technology enough to answer :)

Hi Joe,

Yes, it is possible to bridge the two channels on each board for more power, but it will most likely require more heat sinking, as well as some serious modding to each board (cutting traces, adding jumpers, etc).

Also, I wouldn't consider this to be true dual mono unless each channel is powered from its own battery.  

Finally, while you may get more power, this does not guarantee that the amp will sound better....  :wink:

Regards,

Each channel of the Teac is already configured as a bridged amplifier, specifically a single rail, bridge tied load, (BTL), inherent in the Tripath TK2050 chipset. Two channels cannot be bridged, but they can be paralleled, as described in the datasheet -
http://www.tripath.com/downloads/RB-TK2050.pdf
This is not practical for the existing Teac boads as it would require -
1. Implementing jumpers to configure it for parallel operation, which would have to leave the circuit board/ground plane, exposing signals to rfi and current loops (in technical terms, a roiling cauldron of crap) and
2. Consolidation of the 4 output filter toroids (2/channel) to 2 larger, higher current output toroids for the now paralleled output.
