First post! I have a 2.1 setup for my relatively small living room comprised of two BIC PL-89 and a Monoprice 15" THX. Up until recently I have been using a TX-NR676 which has decided to Onkyo itself and seppuku the HDMI board. My general media consumption is an nVidia shield (HDMI) and a turntable (RCA). With my minimal amount of devices and relatively “powerful” speakers, I was looking into just running a dedicated amp to get above the normal receiver output power limit of 100W or so for an 8 ohm speaker. The biggest issue I have right now is figuring out how to manage my sources into the amp.
Today I got a Behringer KM750. Was this a good idea? It seems like people mostly use this for subwoofers. I set it up today and it seems absolutely miles above the previous setup, however I’m now chasing an audio hum.
When using RCA to XLR cables from my TV it’s the worst, however switching to purely RCA cables it gets better. I’m concerned since I also have a Behringer CX2310 in the mail too, which only takes XLR. Would the addition of the crossover help with the hum? Should I look into some kind of Optical to XLR device? Should I get one of those “HDMI Audio Stripper” things? I’m confused and scared, please help.
