Phoenix Gold Phorum

not sure what's going on here, in my last install i had no issues at all turning 5 pg amps on, now i'm using hifonics viii stuff and if i connect 2 amps to the remote outs of the dd10 it trips out and resets it self over and over again until you pull the power...

the only way i can run them is to use the remote outputs for the accessories...

also noticed that the interior light dims when the amps turn on especially the sub amp

any clues what's going on?

So, do the amps turn on if you run the remotes seperate from the DD??

ie. if you use a relay for the amps does everything work fine or are the int lights still dimming???

that is a strange one. it doesn't blow a fuse it resets? I would suspect something might be wrong with the internal relay on the DD10

Many be A blown or lose wie on the dd10?
maybe a lose ground?????

I wonder if it requires more than 500mA to turn on... in that case you might need a relay

I wonder if you can share multiple outputs to get more than 500mA out of it... the regular remote outputs are fused at 1 amp I think.

if i use the regular remote outputs (1amp) then it powers on but i still get the interior light dim...

the amp remote outs only have a relay which constantly trips if more that one amp connected, strange

1st thing would be to grab a DMM and check how much current draw the amp remote on is trying to draw.

Something odds going on here...... Have you tried using other amps in place of the Hifonics and seeing if there is any difference??

an amp meter would tell us if it is too much current. Remember that it needs to be wired in series rather then in parallel like when we measure voltage.

will try this...

something i noticed though, if i hook a Thor and Zeus up they start ok, my Boltar and Colossus are the ones that have an issue if i wire one of these up with another amp it trips out.

they are ok with a 1 amp accessory remote out bit this defeats the object of having such a unit!

they're not drawing a lot, about 0.003amps.

don't know what to to check next...

Whats the DD drawing overall??? Try measuring it with nothing connected and then measure it each time you connect an amp to it (1 at a time).

Perhaps there is a fault with the DD which is causing it to play up once it reaches a certain current draw through it's outputs??

this sounds very very strange to me which would leave me to ask about the old electronics stand-by, have you checked your grounds? Look inside the DD and maybe tighten up the mounting/grounding screws and see if anything changes.

i think power and earth on the dd10 are not an issue (although i will check) because the amps turn on ok if i use one of the accessory remote outputs which are 1amp rated, only downside of this is the amp connected there turns off the same time as my eq and x-over...

the issue is with the relay side of the dd10 that controls amp remotes, there are 2 inside the dd10 and it's only allowing 1 amp to turn on at a time...

UPDATE.

this is now resolved, the problem was my nakamichi headunit belive it or not! no idea how this could happen but i put the denon/pg unit back in and evrything works like a dream!

Weeeeird. The DD10 should have relays for everything, so I don't understand how it would fail to turn on.... unless the Nak remote was so weak it couldn't flip all the relays???

either that or i used the wrong remote out on the nak, i'm almost certain i didn't but i could of used the electric aerial output..

i've now got 4 hifonics amps turning on perfectly from the correct outputs of the dd10

nak and service issues, birds of a feather, pretty much why Nakamichi stopped importing into the US a few years ago, just Canada, and supposedly that has stopped now as well- nice hu when they work

this is true...I love the cd700, but the local high end boys have said they won't deal with it anymore as all nak stuff they sell comes back with issues...On a very frigging spendy unit at that.

Hey dave...getting ready to toss the new exile 2400.1 in the car running two ti 15s at 2 ohms I've got to build a box on sunday for the mojo but we shall see how the amp does...at 2 ohms it is spec'ed at 1600 rms...that isn't too far over the mark for the ti's...won't be burping em or anything

I don't post often, b/c well I don't often have experience with the hardware being talked about, but this time I do. I have a Nak CD500 and it is connected to a DD10 as well. I have not had any issues with the Nak in general or in connection with the DD10. I have four fans, exile 2400.1, M44, TiDEQ, and Phoenix line driver connected.

I would venture to say the light dimming would have more to do with the amplifier powering up (read amp draw from batteries) than the method by which it was turned on (remote getting power), but I could be wrong. Is this still occurring with the other headunit?

Perhaps also those two particular amps power on at the exact same time (ie some older electronics might have some regulator on the power supply so it is not instant on)? Again I don't know anything about those two amps and even if it was the case, the nak headunit should handle it. Maybe there is a difference in voltage output on the remote from the one headunit to the next?

As far as Nakamichi hardware this has been my first headunit from them and I have loved it, I really should start listening to better music versus the radio.

i took the big colossus out because it wouldn't calibrate with my velodyne so no idea if that would fixed itself.. but your right, probebly just powering up like a powerstation!!

that is strange.............
