Left RCA out on DAC not working
Hi guys,
As per title, the Left out RCA socket on my DAC is not working properly.
It will work, but only with RCA plugs with non-metallic shrouds, such as AECO plugs. I only discovered the issue when I went to try other interconnects. I started off with my Lavri Grand ICs which have AECO plugs, but all my ICs with metallic shrouds around the pin don't work at all.
The DAC is relatively new; I contacted the distributor, and he thinks it's a badly soldered ground on the inside of the chassis. He's ordered me a new unit, but has been admitted to hospital for major heart surgery, so I may have a bit of a wait
Anyway, is he correct in his assumption of a bad ground solder inside on the Left RCA out?
Thanks in advance
@jea48 HI, thanks for your reply. The AECO plugs have no metal on the plug shrouds inside, apart from the pin, whatsoever. The Lavri/AECO work perfectly. With other ICs, that have metallic shrouds, the left channel just doesn't work. The right channel works fine no matter which ICs I use. Checked and double checked with 3 different ICs, all fully inserted. |
Is this what the plug looks like? I can see the signal ground contact on the bottom of the inside of the plug "shroud". Look at the bottom of the inside of the "shroud" in the photo. Look at the photo of the cable connection plug. Note there is a center contact terminal solder connection as well as a signal ground contact terminal solder connection. The signal ground is required. It is part of the signal circuit. Often called the signal return.
It has to be the center pin of the plug is not making contact to the center contact in the left channel jack. It sure looks from the photo I provided the center pin on the AECO plugs have what looks like a longer center pin than normally found on RCA plugs. Is that the case or is it just the photo that makes it look that way? .

@jea48 thanks for taking the time with this; I'll take another closer look. If I'm wrong about the AECO, any idea why the left channel would only work with these plugs, but no others? Seems a bit odd, even to my ignorant brain (in these matters) 🤔🙂 |
Just to narrow the problem down to the DAC left channel RCA analog out jack did you try another set of Line inputs on the preamp to make sure it's not that left channel input that causing the problem. Or even try swapping the right and left ICs plugs at the preamp and see if the problem follows the DAC left channel IC to the right channel of the preamp. |
