Cubilux 3.5mm TRS Line to Microphone Attenuator Cable, 3-Level (-10dB/-20dB/-30dB) Attenuation MIC Cord for DSLR Camera, Camcorder, 1 Feet

proper attenuators are big and bulky. because of the stuff in them takes space. Amazon has proper boxes but I am looking for something smaller/lighter/cheaper that's not some garbage like this which I would still need an RCA adapter for. I'm trying to minimize my grams and volume load out, with something that won't cause problems preferably at a single fixed value that doesn't have to be worried about ever.
