Is there an OP Amp that is a pin for pin replacement for the 4560 Op Amp that will plug in and sound better? |

Yes and no. Swapping opamps can be simple. First of all, what role do these 4560 opamps play in this desk? Mic amplification? Buffers? You may find that these cheap opamps do their job just fine. The most common audio opamp is the NE5532/NE5534. When choosing a substitute, you must pay attention to power demands and stability (at least) before trying a substitute. Also, You did not say if the 4560s were DIL or SIL. PS. If you don't think the desk sounds good, then my advice would be to not buy it. |

Data sheet for 4560 is in the below link; http://download.siliconexpert.com/pdfs/2004/0629/semi_ap/1/r oh/qd/ba4560.pdf And below is pin by pin replacement; OPA2134 http://hjem.get2net.dk/tkhifi/data-blade/opa2134.pdf Just google the word opamp data sheet or something like that. You will connect you to loads of sites where you can download data sheets of various opamps. However note that there is a lot more than simply unplugging one opamp and plugging another even if they are pin compatible. You have to be able to understand what the data sheets say. It is not a rocket science but some basic knowledge is required. See how you get on. Cemal |
