I have a Sony tv connected to an 851a, which then runs a homebrew soundbar. I’m connecting the tv to the amp via the 3.5 headphone Jack from the tv to rca on the amp. My issue is the volume control has to be set halfway on the tv and up quite high on the amp. Can I use any other connection to the amp that gives a true audio gain to the amp? Here are some pics of the back of the tv
I had a similar problem with my TV. One of the issues that I had was excessive bass during the action scenes, but dialogue was very low. (Common problem on a lot of films). To hear the dialogue at a reasonable level, you had to have the volume quite high, which made the bass far too loud, to the point that the neighbours complained. Another issue was that the input level to the amplifier was always louder than any other input.
To overcome this, I got a nine band graphic equaliser, which I put in line between the TV and the amplifier. Lowering the bottom end bass and raising the top end treble for the dialogue. After a bit if tweaking, it is OK now with an acceptable balance. On mine, however, I have the volume on the TV set to Zero and control the volume via the amplifier. The inputs from both the streamer and the TV are both now at the same level, which helps with the volume.
