I found on net that Z-2300 uses Class-AB power amplifiers from STMicroelectronics. But i am not sure what type of chip it uses. Can anybody help me out? Thanks in advance.
Some websites are saying it uses 2 X TDA7295 chips bridged together for the subwoofer & two TDA7296 for the two satellites.
Now, this quite justifiable considering two TDA7295 bridged together will pump out 80 X 2 = 160W. Subwoofer is rated at 120W by Logitech, so the amplifier have enough headroom to produce distortion free bass even a full volume.
While for satellites it uses TDA7296 each capable to deliver 60W. Satellites are rated 40W by Logitech, so their is enough headroom.
Currently some websites are calming Z-2300 has four TDA7296. So the subwoofer have 2 X 60 = 120W with no headroom with still matches the Logitech's claimed sub output.
From the Logitech website I found out that Z-2300 have two model generations
1) M/N: S-0118A
2) M/N: S-0118B
This numbers are printed at the back of the subwoofer.
Is the second model a low grade model than the previous one?
