Thread: Serato SL1 ac adapter

Just wanted to ask anyone who has one of these, or anyone who knows about the requirements of the SL1 box.
I know the SL1 box requires 9Vdc and 300ma, and I have got myself an ac adapter which you can switch the voltage on. I switched it to 9Vdc, but it also has another switch for polarity. Basically, you can have the tip of the plug sending +, and the edge sending - or switch it and get the other way round.
So, I am wanting to know which polarity setting is an original SL1 ac adapter, is it + to the tip, or - to the tip (of the plug - which goes into the SL1 box)

positive to the tip...at least that's what i set my ac adapter to

I wouldn't trust them universal adapters as
the voltage ratings half the time is never what they say

and if you get the polarity the wrong way round you might damage it

Nik - I found this on the Serato forums:

9v DC 400ma power supply OK for SL1? | Serato.com

Might be of some help mate.

99% of the time, on any piece of equipment the tip will be +ve, but there are exceptions. Simple way to test would be to use a multimeter on continuity setting to check for continuity from the sleeve on the power socket to the sleeve on the RCA inputs, if that is a short then 100% the tip is +ve on the power connector. If you don't have a multimeter you can make a continuity meter with a battery, 3 pieces of wire and a small light bulb or LED.
