longdrive03 Posted July 21, 2018 Share Posted July 21, 2018 I've got several of the T9A's andd am going to use them in a AB-2 Belle crossover. They have 3 taps 0, 4, and 5. I think the 0 is the connection for the negative but need to know which is the positive lead connection coming and the tapped connection going to the midrange positive input. Looks like T9A has -4db attenuation and will work well with a 13uf cap for 500hZ crossover with 5mh coil in parallel. Any help appreciated. Thanks.

mboxler Posted July 21, 2018 Share Posted July 21, 2018 The T9A actually has -3db attenuation. The T4A has -4db attenuation. Looks like the T4A was used in the Belle AB-2 crossover. If using the T9A... Hook input - to 0 output - to 0. Hook input + to 5, output + to 4. Mike Quote Link to comment Share on other sites More sharing options...
