I have split cabled our t-box signal to a second TV in a nearby room (so we can watch same show in that room). The picture is fine but the sound is very low and requires the TV volume to be maxed out. Was considering buying a sound bar to amplify the sound but suspect this avoiding the root problem...any suggestions where to start?

How have you split it?

we called in a tv aerial/cable company to mount a splitter box in the lounge and run a separate coax cable under the house to the family room.

One person supports this post

Is the tbox unit itself set to Max volume ?

Also, what sound settings can you change on the 2nd TV? i.e. EQ and those preset sound modes???

The T-box is set at max volume. The 2nd TV volume is also at max volume and if we attach an xbox or other peripheral device via HDMI we have to turn the sound down immediately...

RF is always the lowest quality output. I don't have any explanation for the low sound, since the T-Box is outputing at full volume.
Is the TV tuned correctly to the UHF output? If it is off slightly then it could be possible for audio to be lower.

Another explanation is that audio output over RF is mono. The Tbox does not have an inbuilt NICAM encoder. I would probably put that down as your issue. A connection via component or AV would be better over RF. Or you could try an AV audio/video sender with remote extender.

If you split the av left/right stereo output you will lower audio quality (half level, poor impedance match, etc.). Take a photo of what you have done and post it.

Thanks everyone for the ideas. I've decided to try looking for a TV out socket (hopefully HDMI) from my Denon 3313 receiver and run this cable under the house and up to the second TV. Hoping this will not only fix the sound but allow the HD picture to pass through too...?

Must admit I hate going under the house as it is only 60cm clearance but perfect AV is worth some hassle!

Nice receiver! You have 3 HDMI outs so that isn't a problem. Use good quality HDMI cable and if you are going more than about 10M in length you may need a booster. Look at HDMI over cat 5 or HDMI over coax solutions too.
