Chord Hugo - Page 423

post #6331 of 9120

I have just turned on one of the prototypes, it has not been used for months. It turned on fully charged at blue. It should not discharge in 24 hours with the on off switch set to off. Note no charger was connected. Do you have the charger connected but that is also off?

Mine seems to deplete in 24h even when the unit is off. :confused:

Thanks Rob.

The first time I had my TeddyPSU connected and OFF. My thought was that the Hugo indeed discharged in the PSU.

 

I tried with the PSU disconnected and the battery depleted in a day all the same.

 

This could explain why it took literally 3 hours to have the first sign of operation from the unit when I received it (I thought the battery or the charger was dead. I was expecting it to come alive after ~30mn).

I suggest that using the simple charger that chord provide with the unit is the safest option. Aftermarket wonder power supplies often aren't they are sometimes half baked designs from dubious companies that do little good and can sometimes do major harm.

Chord have had a couple of failures of the over voltage protection, which is used to protect the charger. This has been because people have not been using the supplied charger, and using PSU units with too high a voltage, which then damages the protection circuits. The protection is there for transient events, not constant over voltage. 

 

It sounds to me that the protect circuit has been damaged, so you will need to send it back to your dealer for repair. Do not use other PSU's apart from the supplied charger - there is no benefit in sound quality with using other chargers, and there is a risk of damaging Hugo in using other PSU's.

The thing is, it already had trouble when I first got it (at work).
A white LED was flashing inside but the charging LED was OFF.
It took 3 hours for the things to go back to normal (charging LED steady, boot up sequence on power on).

This was with the supplied charger.

I think what was happening was that when you first tried to charge your Hugo it's battery was completely discharged . When in that condition the batteries take a little more power than when they are just very low. My guess is that you tried to charge Hugo with the unit switched on and because the battery needs more current when totally flat ( discharged) that the charger could not supply enough power for both the Hugo and it's very discharged batteries. All you needed to do was to switch Hugo off for only a minute that would put enough charge into the batteries to reduce their charging current so that you could then switch the Hugo back on and the charger would then Have sufficient power for Hugo's circuits and to continue charging the batteries. So when charging fully discharged always switch off for a minute or two.

For once my cheapskate ways have actually saved me some pain - I use the stock charger because I'm too cheap to invest in anything else !

no, the unit was OFF when charging, of course. It's only after X minutes that I repeatedly turned on the unit to check if that was it.
I was expecting few minutes before ready, like you said (like my Ciunas DAC and Converter)... It took 3 hours before I could see the first proper boot sequence.

Well, Hugo is battery driven and using an expensive charger/power supply will not improve the sound (at least not in theory). However, if the connected power supply is very noisy (or with the wrong voltage), it may however instead deteriorate the sound and may even break the unit...

Sorry for my silly question,but i wonder which dap/portable device has a decent coax out to feat hugo??
How is the fiio x5/dx90 feated to hugo by coax out,anyone experience it??

Is it OK to leave the Hugo plugged into its charger (and into AC power) all the time?

(I'm not sure if I saw this mentioned earlier, so apologies if it was already asked.)

What is the actual electrical input that the hugo takes? I have a LPS with extra rail and curious if it will make any difference even though it shouldn't.

For above poster, I believe hugo is lithion battery so always at full charge will decrease life of battery. You should run it down and charge back up.

I had used dx90 coax to Hugo and it works well with its short stock 3.5 to rca cable. Not sure I can pick out any differences compared to using my HM901 coax, or AK240 via optical.

From the Hugo manual: It is safe to leave the power adapter connected continuously to charge and power Hugo.

While it is safe, not good to leave lithium ion battery on full charge all the time as it will affect it'd long term capacity in negative way. Lithium ion batteries like to be used but not fully discharged.
