Supplied Ferrites all have small knot in one wire - nellyt - 2016-11-02 The pre-wound ferrites that came with my Blue kit all have a small loose knot tied in one of the two wires. What is the significance of this? Should this be connected to a certain pin of the pre-amp? thanks RE: Supplied Ferrites all have small knot in one wire - elythomaslumber - 2016-11-02 (2016-11-02, 10:15)nellyt Wrote: The pre-wound ferrites that came with my Blue kit all have a small loose knot tied in one of the two wires. Connect those one with the knot to the + terminal.

This is a TOA / TOGA system, and all it needs is stroke impulse data. The polarity would matter if this were a DF locator, which it is not. It's good to keep 'consistent' however, since it is possible, if you do everything correctly, (Same polarity, Correct physical orientation) using two ferrites at 90° to 'eyeball' the direction of a signal on local signal display...e.g. attached.... which can help track down "interferers"(2016-11-02, 10:15)nellyt Wrote: The pre-wound ferrites that came with my Blue kit all have a small loose knot tied in one of the two wires. |
