## Questions & Answers

**Q: About the input, a 3.5mm mono tip sleeve plug grounds the input, so I at least know that it uses the ring terminal.  Does it sum the tip & ring?**
A: The input is stereo summed to mono by way of the NE5532 OPAMP. If your input cable is mono (tip/sleeve) you need to make an adapter to send the tip wire (+) to the ring and tip (L+R) terminals of a 3.5mm stereo plug. That way you get full use of the 3116 chip; 100w max.

**Q: This amplifier, (5532) is listed as full frequency and a subwoofer power amp. Which is correct and what is the output frequency?**
A: There are two models. Not sure what low bandpass it set at on the subwoofer, but they are identical beside that. If your source has a built in Subwoofer option already I would just use the full frequency and adjust your bandpass at the source.

**Q: is there a drawing of the dimensions of the mounting holes so i can make a case for it?**
A: I do not have a drawing but the relevant dimensions are approximately 2 7/8" and 1 7/8". Hope that helps.

**Q: Does it come with instructions or a wiring diagram?**
A: One of the pictures in the product description clearly show the connections. There are only 3. Audio in (3.5mm jack), audio out (terminal block) and 12v power.
