SPD-HRISO - Power Isolator Converter

This does the trick, i can power all my receivers with no noise by using it.

Does it, but you may need one for every accessory

I use an F8n Pro and have Sennheiser G3 receivers which are battery eliminated with Sennheiser DC-2. I'm using a Remote Audio Hi-Q 98Wh battery connected to an SPD-1. If I connect this power iso in between the SPD-1 and the F8, the receivers are afflicted with noise (though many times better than NOT using the power iso, still unacceptable). If I connect this power iso in between the SPD-1 and DC-2, the noise floor coming from the G3 receiver becomes less than that of the normal preamp noise floor - meaning, it works, BUT, that means I have to have a power iso box for all four of my receivers. Cumbersome and a tad weighty, but maybe still less annoying than changing batteries on the receivers? You decide! Also note, the iso outputs a regulated 12V. I wish the isolation was just built-in to bank 2 of the SPD-1, even if that means it were a bigger unit. Perhaps a wish for the SPD-2.
