Set it to 9V. Setting it too low won't work. Setting it too high could in worst case damage the hardware, I reckon.

There are two kinds of power adaptors, regulated and unregulated. Regulated adaptors have a circuit with a few transistors that cause the voltage to always remain the same. Unregulated adaptors output a higher voltage which drops as you draw more current. You should be fine with your powersupply as it has the correct current rating so it should be under load when powering the box.
Regulated supplies are better because they offer a smoother output which is much better for powering things like preamps.
If you set the polarity (+/-) switch to the wrong setting it just won't work, there should be a diode inside the box to stop it from damaging the components

thank's for explaining how that works!

so i should set my supply to 7,5 volt (1 step below 9volt as suggested in the manual), because of the higher output?

@revolutionary: thats my problem. the output is maybe higher than the calibrated 9volts, and ruins my box.

if the voltage is too low, then the seratoboxpowerLED will just stop shining, and it will take power again from usb (no damage beacause of too low volts). is that bad when this happens, because then i mayber try 9volts?

or maybe i'll just get that regulated supply, beacause i have the gift, to accidently bust electronic devices, and i still not understand the voltage-thing 100%.

I suppose you can set it to 9 volt, that means it will have a higer voltage without load and about 9 volts with the load from the SSL box.
Also is a bit higher voltage not likely to damage the SSL box, it will just get a bit warmer.

Why do you need a power supply by the way? Thrus? Couldn't you test the voltage in some way just to be on the safe side? But as bartaug said, a little more is not likely to damage the SSL interface.

its good to have power to the box incase of having to restart or if you have to close the program. i beilieve once the power is not going to the box that audio will not go through it right?

Once you turn off your computer, no sound will go through the SSL interface without an external power supply.

i need the supply cause i dont scratch with ssl all the time plus my computer has problems with usbpower (i have to unplug/replug every time i boot)

i can't test voltage.(knowledge bout electronics=0) but i found on an electronics-forum, that unregulated supplys have voltageoutput in standby like this: calibrated voltage*1,414. in my case 9 volt will output 12,761volt (to much) and in 7,5volt -> 10,6 volt.

so i think i will do it with settings to 7,5 volt.


dj synystr:
my mainboard keeps powering the usb port, even if the pc is shut down. so aslong i disconnect powersupply from pc the box will have power. BUT somehow my pc has problems with starting with serato. i have to unplug/plug it everytime so windows detects it.

3 questions: isnt it bad if the box has power 24/7?, to low voltage wont damage my box?, regulated powersupplys are better serato?

this is what i did. go onto EBAY and look for 9 volt power supply or some other type of multi power supply that you can change the settings of. i got one off ebay for about 10 bucks shipped. it has 6 different terminals and is switchable from 1.5 volts to 12 volts. the polarity of the plug is switchable too. meaning inner post positive or negative. as long as you get one that does 9 volts your good to go. im not sure what the polarity is on the Interface maybe someone could cue in on that.

polarity of the box is centre pin positive ring negative

there ya have it!

the only one i found today was a 9V-1000mA.

i'm still not completly shure if i can buy a 9 volt powersupply with 1000 mA output. is that 100% certified, that this only means it "could" supply devices up to 1000mA. Because if the actually output is 1000mA this maybe damages my box.

anyway, tommorow i'll look for a 9v/300mA + regulated. hope i'll find one.

That one will work perfect :) I use the same type at home and work for testing.

perfect!

they guy at the place where i wanted to buy it, said 1000mA are to much for my box.

but when you say it shaun.... :)
its mine tomorrow

just hypothetical: 9V/2000mA wont damage the box either.
so voltage must be correct, ampere-output is mostly unimportant.

the 2000 stands for miliamp hope i spelled it right. voltage is what you need to be concerned about. i believe ma helps when your figuring out loads for parrell or series, i think.

Basically, the mA (or milliamp) spec of a power supply refers to the amount of current available, which is different than the amount of load it supplies, so hypothetically a 9V 2000mA wouldn't make any difference.

yeah i thought i was kinda right.

Thanks again for help, Shaun. I'll get that 9V/1000mA tomorrow.

a 9v/1000mA is fine as long as the voltage is regulated, if it is unregulated then the voltage will be way too high for the box. On the other hand a 9V/300mA unregulated supply will be fine because the current and voltage both match the requirements.

i already got an unregulated 9V/300mA. But i am very scary person, and so i get this regulated 9V/1000mA.

Regulated power supply, good choice, phil.

:) i found a 9V/300mA regulated powersupply at an other store today. everything works fine. phil is happy.

btw: do i have to poweroff the box after using it? because right now it seems that the seratobox has power 24/7 until i plug-off the powersupply + usb. (My main-music-computer somehow powers usbport, eventhough its not running)

Protect your environment, save money, and power off anything which doesnt need to be on. Having a unit on usually cuts down the lifetime of it...

Well, it depends, nik. Turning your computer on and off all the time isn't exactly good either if you know what I mean. But totally do this with the SSL interface.

Yeah, agreed. You also shouldnt power off and on your harddrives all the time, as well as your LCD display, in general devices which have lots of mechanical parts (LCD display? LCD lamp behind your display), but this is not the case with the SSL amp.

I guess if you plugged it in and out all the time like every minute or something you could damage it, but that's not the case.

i dont find that word in my dictionary. so i'll get this " www.elektrosmog.de (picture)" and connect my serato-pc and serato's powersupply to that, so after using i just poweroff this "socket-thing" and pc and powersupply are completly shutdown.

Yeah, that's a nice solution. Just remember what nik said about HDs and similiar. Also don't plug too many of these into eachother. Boom! :D

learned alot! thanks guys! i'm feeling like an electronics-expert right now ;)
