Replaces old and noisy NF2 relays with modern sealed Panasonic relays like in the pictured Helios module. This channel module was very noisy and unreliable until this relay was replaced as it switched the audio path between Mic and Line, so all signals going through the old relay were noisy and intermittent. You can still find these NF2 relays around but the Panasonic offering has far superior reliability for years to come.
Please note that the Panasonic TQ2 Series relays are polarized and may need to be flipped to the bottom of the card to work depending on the application. Confirm voltage polarity in the relay activation circuit before install. Or if you prefer, solder it in and try it! The reverse polarity wont hurt the relay, it simply will not work. If you do not at least hear the relay/s clicking on activation, you can desolder the TQ2 and resolder it to the underside of the PCB, all other connections remaing the same. Ensure the coil indicator line on the relay goes to the same two holes as before. This will flip the polarity of the relay, with all other function of the adapter remaining the same.
