Filtro XLR-DC

My tweeter amp was running hot and the DC filter fixed that right away, plus the noise floor dropped noticeably. It's inline and simple to hook up before the amp. Solid little accessory for the price.

Bought this to kill a faint hum riding on my signal and it did exactly that — dead silent now. The inline design means no extra rack space, which I appreciated. Amp runs cooler too, seems like it's not fighting DC anymore.

Plugged this between my preamp and power amp after chasing a hum for weeks, and it's completely gone now. The inline filter just sits there quietly doing its job, and the amp runs noticeably cooler too.
