"The signal flex line transformers are made for adapting a XLR low impedance (500 Ohms) signal to a 1/4" phono type high impedance (10K Ohms). There is no right way to do it except to match up the impedance correctly. Many people ask for xlr to 1/4" cables and state they have seen them before or even have them. They do exist, but for a different reason. They are made for less expensive Hi Z microphones for the simple fact that they need to use a connector that locks into place. there is not 1/4" connector that locks. Therefor, the 3 pin XLR connector is used, however, they only use two of the pins and wires. By using one of these cables like an adapter, you are running your neutral through the gound wire which can result in hums and bizzes, not to mention the fact that the signal is so far out of balance. If you want to do it right, you need an impedance matching transformer. Why let the cost of an adapter ruin your sound. Please note that this model is a rigid adaptor. Once you plug your XLR mic cable into it, you have a pretty large rigid mass you are pluging into a small jack. If it is not a permanent installation or is not in such a position that it cant be bumped, we strongly recomend the SF8021 wich has a 6" cable between the transformer XLR end and the 1/4" plug. With all that mass, if you bump it you could easily break your jack and that can be a costly repair. It is also not recomended you use this one if the plug is on a vertical surface whereas, the mass of the load will be pulling down on the jack."
