Hi,
I had to open an audison LR605XR 5-channel amp to replace a trimpot in the crossover and have some some questions.
I "think" I can clearly identify 6 channels. 4 small channels with 1 pair of OT each on the input side of the amp and 2 bigger channels with 6 OT each pretty much in the center of the amp.
I initally thought that the signal for the subwoofer was splitted off on the input board, probably summed in some way and amplified, thus 5 channels.
What is the usual way 5 channels amp are build ?
Just curious on this one, as I thought about checking the bias before putting it back together and that question puzzled me, even if not directly related.
Thanks in advance,
Max

There is no 'usual' way. Each manufacturer decides what's best depending on their target customers or the cost of production.
Sub channel consists of two amplifiers in bridge configuration, each with 6 OT. This is in order to obtain high power with the same power supply voltage of other channels
