The NE5532 Preamplifier Circuit. The IC1 is set in non-inverting mode. So, the input and output have in phase the same. And, the output gains at pin 1 depends on R3, R4, R5, R6, and R2. Next, You can choose only one input channel by rotating switch-S1. Which each input channel has a different amplitude.
