why 5 pin DIN cable for AC?

hi there,

5 pin cables are sometimes used for stereo audio: 2 pins each channel (out and in),
1 pin for screen/ground

but how about AC? the above power supply give you 9V DC, through the usual barrel connector, but then also 13.5V AC through a 5 pins cable? what for five pins?

best, paco

The supply you show is for a low power use.
I own three preamps with separate power supplies.
Two use industrial sort of multi-pin connectors, but both of those have TUBES, so the voltages and amperage in use are higher.
My Bryston solid state preamp power supply uses a connector similar to the one shown. (even though it costs $5,000) With the low amperage needed. fractions of watts, the connection does not need to be very robust.

interesting; yet i still don't understand why those brands use so
complex 5 pins DIN connectors for AC? for AC you need just 2 pins!
i wonder how they wire/solder so many pins?

also, did you try to replace the stock cord from power supply to preamp
by a better, more "audiophile" one? with those connectors that might be rather difficult!

For your main component, the only way to get improved power is to replace the internal power supply with a larger one, or use an outboard power supply (like the one you show).

Your main component AC power supply is obviously a 3 phase + neutral + ground, so the only way to connect to a larger outboard power supply is using a 5 pin connector.

3 phases give you balanced continuous power versus single phase.

Hope this helps.

thanks! now i fully understand why they use 5 pin DIN connectors...

BTW, do you think i could use the below cable, which is made for audio signals,
to replace the on the shelf cable which comes stock with that power supply?

best, paco

If I had been the project manager for that PS I would have insisted on different connectors for the two different voltages so that there would be no confusion when it came time to plug in the cables. Apparently, the actual project manager for the device agrees.

That's a Aune power supply (edit: delete "upgrade") and the AC and DC ARE two different output connectors.

The barrel DC 9V is for the X5S
The din AC 13.5V is for the X1S/X7S/T1 SE

Interested in knowing what the project manager meant? Sorry, I am only a little familiar with the Aune line.

Cheers!

The cable you show is for audio interface. Off the top of my head, I honestly don't know if the cable portion is built different (shielding?) than one you would use for power. Hopefully someone else can chime in, or try googling.

Sorry!

If it's indeed a 3 phase PSU, a larger, more robust, with greater contact surface area 3-pole XLR connector would likely be a better sounding option than a 5-pin DIN plug interface. Perhaps a 3-pole Mini XLR connector and jack would be a good option if there is not enough room for a full-sized XLR jack installation.

Other than an undefined dampened 5-pin DIN connector, there is no other information about the cable. Tough to make an opinion about the worth of the unknown cable vs. the stock cable, of which one also needs information about for a (still unqualified) comparison of the two. Even the notion of a vibration dampened connector is questionable, since the unknown vibration dampening method/material may cause more harm than good if it's done willy-nilly for the sake of a marketing point. The reputation of Premiere brand cables might be helpful, in this case.

3 phase? Please explain.

Read part way down in the Wikipedia link.





Maybe a good analogy is to picture 3 AC currents out of phase so there is never an "off" cycle, or interruption in flow. This is quite advantageous when you are working in AC for small voltages used in audio and broadcasting equipment. And for large industrial equipment, like motors and such. Hope that helps!

Cheers!

I know what a 3 phase 4 wire AC power system is. I just do not understand why a small power supply, made for an audio system, would need to output 3 phase 4 wire.

How does the small power supply create 3 phase from a single phase power system? It can be done, but, it is not cheap.

Good point. I'm used to power supplies and hook-ups from my rock band days. I thought technology has since filtered down to home audio and as soon as I saw the 5 pin din connector I jumped to conclusions. But looking around the net, I think you're right. I found some internal pics of the original posters power supply. Now I'm not sure what the 5 pins are about unless it just different taps off a transformer in the supply. Any thoughts?

Thanks for catching this. I remain true to my tag line.

Cheers!

in the pic you can see 4 wires from the transformer, maybe the 5ht is ground... also, i checked the 5 pin cable connectors and they are all wired to each other, so it seems they really need 5 pins...

Sorry, I can not see anything below the power switch and the hot in and switch leg out wires connected to the switch. The 5 pin DIN receptacle is below the power switch.

I personally know nothing about this power supply. I assume the use of the 5 pin DIN female inlet receptacle is somewhat a standard for 13.5Vac voltage ac out. ???

It is very possible only 3 pins are used on the DIN connector. Two for the AC 13.5 voltage power and one for ground. Only a guess though.

I was honestly convinced it was 3 phase. But I can't find anything remotely close and was picturing the attached. I'm outta phase!
