The NE5532 is in an odd arrangement too. First stage is giving approx x3 or 10dB gain as Mark says. This could drive the output directly but there's another stage as a voltage follower. The strangeness is the pair of 47R resistors with themain output and feedback for the first stage taken from their junction. I just don't see what they are trying to do.
Other oddities include R7, 1M which does nothing.
