Headphone jack to stereo RCA is the way to do it. Did this all the time back in the day to connect tv’s to amps. It’ll also allow you to control the volume via the tv remote.

Just check if the headphone level is controlled on the main volume buttons rather than one buried in the menu.

Looks like the headphone level is controlled in the menu, though there is a another headphone/lineout setting in the menu, and setting that to lineout disables the headphone level.

Those yellow connectors caught me out at first - I assumed it was digital audio!

Brings back memories looking at this stuff! There is a really good market for this kind of thing second hand - presumable people of my age revisiting their youth.

I still remember my first surround sound experience - four speakers powered by something from Toshiba and a house of cards falling around. That was around 1994 or 95 I think. I now work in the AV industry and we regularly install cinemas with 32 plus channels of audio! Absolutely insane how things have moved on!

Yeah, Dolby Surround can be encoded in to analogue stereo or digital stereo......

Thanks for all that info Lucid!

There is - I sold a bunch of early 2000's kit a couple of years ago - B & W speakers, 600 series, for almost the price paid, good money for a mint Sony ES minidisc deck and STR930 A/V receiver. I think the pair of Arcam power amps also sold for original purchase price or near.

Bought the cable, and it does work. But seems I have to remove the head phone jack from the TV if I'm not using the amp. And there's not quite as much volume as when there's direct connect to the amp from a DVD player.

One of these might work better TBH..

I've used one to hook up a XBox One to a Bose desktop speaker setup - works pretty well, although it will be a manual process for switching between TV and amp for sound.

Does this restrict the volume like using the headphone output?

Shouldn't do unless the box itself is crappy.

The headphone circuit in most TVs is pants. There's no set standard for the output level maximum voltage, so whether it drives a connected device well is a bit of a lottery.

An optical or coaxial output gets a cleaner source signal, and the signal standards are more tightly defined. The only possible limitations on volume then are whether the box itself has a particularly low level of output on its analogue connection side, and whether the amp requires a higher voltage (2V instead of 1 or 1.4V) to reach peak volume.

You'll have the specs for the Kenwood amp. It's doubtful whether there's any published spec on the convertor though, so the only real answer is to try it. I would say that the odds are in your favour, but if it still isn't loud enough then you can always return it and try a different brand.

Thats what I used in a very similar situation - old Nad amp with new tv.........works fine.

Thanks for the replies/advice

[blade7]

Guess I spoke too soon about the amp working fine . I moved it to another room to lay a new floor in the lounge, and now the volume control isn't working properly from the remote. The volume dial on the amp moves really, really slowly now, any suggestions?

[Turn7]

Maybe try some contact cleaner on the switch?

[blade7]

The switch, where is it?

[Turn7]

Its the rotary dial you turn…..

So I have to access the rear of the dial?

Probably getaway with just spraying contact cleaner from the front , at the spindle.


I am not an expert, it’s just what i would do.

Remove the power of you do try this.
