ahh no, thats good I prefer that its only connectors! I have plenty of wire for the cables.
this was not clear, hochopeper was confused also, we both thought you meant cables, but its not a big deal I prefer it this way. hows this for an annoying failure, I waited around this afternoon for the package, it goes most of the way around the world, seemingly taking the scenic route and then … Quote:
![]() it must have been literally minutes away from my house. didnt even get an email either, not pleased with that. btw..my frustration was never about being in a rush, but yes i'm less uptight now after blowing off steam and knowing all is in motion. you are also less pressured so less likely to react, so its all good =) besides now I have a new target, UPS!!! breakdowns are unexpected, thats cool, but given they scanned it and didnt update me; thats pretty poor service. very happy to not get a band limited amp, I would have thought I broke it, or it broke my system

sorry, i joke. strange...ups have big force in the world. first reason i remove from package amp. now i set flat 10Hz--40Khz (-3dB) and only 1dB from 4R to open load @40Khz

no I think they must be pulled by ponies, they mean it when they say horsepower over here. maybe they ran out of carrots?
should be interesting the amp. can you tell me how much power is available in the power supply pass through output in addition to powering the onboard amp with say 200W? what voltage? |

better explain MDA-400: on board realizze one dps-400(psu)+ one SDA-400 with power supply bus for other one SDA400. i send you setup as well,240w(4R).(with bus for +/-53V and +/-20V aux) then is possible supplies one sda-400 module eg. 120w(8R). tipycal for bi-amp use. depeand setup, max power possible on mda-400 (psu section) is 600w. obvius that this module are created for modular system very compact. this setup i send you, produces quiet 240w at 4r and 420w at 2R without heatsink. absolute clean as 8R. apart is not simple destroyed this amp eheh! you want try different setup?

yeah I realize that mate, i've understood and youve given me the info I need anyway.
What I want to do is power or at least connect a second pair of 'the wire' aside from the one i'm using the dps600 with, at the same time as the onboard SDA-400. I read that there was this power output for powering a second SDA400 and thought I would try utilizing this connection to make easy and fair comparison between the amps, or to gain an easy extra power supply for testing. this way I can easily compare subjectively the class D on the SDA400, with the class AB the wire while fed with the same quality psu, as in exactly the same power supply. obviously I would need to supply an extra linear higher voltage supply for the front end of the wire, but thats easily solved. sounds like a good plan yes? |

well here we go!
so Roberto, couple of things, not going to make a big deal about either of them. • both Chris and I asked for green covers on the power unit, we got black, which is a bit dissappointing, but i'm not going to send mine back for that. a photo at some point would have highlighted this. As soon as I saw the green photos, I sent you an email on the 2nd of June, saying I definitely wanted green, provided it would not cause delay.... • one of the units does not have the main output connector fitted and its not in the bag. this would also have been picked up in a photo. I dont mind too much, i'll probably hardwire the outputs after testing, but i'll have to use clipleads or something for now. other than that they were packed well and arrived safe and sound, wont fire them up today, maybe tomorrow |

is the power unit cover replaceable? like could I swap it if you sent me the green ones? I really liked how it made them look even more modern.
how did you test the one with no main output? clip leads or something? maybe you left the second connector off as I asked to leave them off, but not both? haha like I said its not a big deal, just trying to understand. anyway i'll take this to email. maybe you could send green covered with the amps if they havent gone already. we'll get back to build and application here, better get something ready to test and clear the bench. keeping the goal in mind. sorry said I wouldnt make a big deal out of it, i'm not, its not a dealbreaker Last edited by qusp; 18th July 2012 at 05:50 AM. |

Hi qusp, I feel that because of the color, you're not happy. I warned hochopeper in a reply email before sending. (please, ceck it) the company that provides the covers for the power unit, had assured the supply, that's why I said that there were no delays for green. Instead, we are left only with the first samples. Unfortunately you can not replace it. the interior is resin, even if you see the nylon screws under the PCB. we can disassemble (18 pin soldered) to remove the power-unit. Also, this new green painting was created for us (with custom Polymer). new delivery date is now late July (i hope) becouse new amplifiers use this. I can change later, the DPS-600 if you want. Also I see professional black matte. yes, i remember you not want connector, remember at 50% haha!
For test, i use with computer bank. connectors to plug interface and software running on all controls, function, current (pulse & continuous system). result is all in the parameter range, including efficiency. well, I still have the instructions for this DPS-600 for you, some important. ...woW! i see very nice smps in your photo
