<b>Short-circuit protection </b> </br> All 10 outputs in this unit have separate short-circuit protection, i.e. Short circuit in one channel won't affect other channels' function. Under the circumstances of all LED lights on, LED light of the short-circuited channel will off, while lights in the other normal channels are still on. This helps locating the faults when there were short circuits among many effectors. </br> </br> <b>Switch For LED Lights </b></br> Turn the switch towards those LED lights, normally all lights would go on after the power is connected. If you don't want all LED lights, please turn the switch back.</br> </br> <b>Specifications: </b></br> Material: Fireproof Plastics ( ABS+PC ) </br> AC Rated Input: 110-240V , 50/60Hz </br> AC Outelet Rated Output: AC 100-240V , 50/60Hz, 600W </br> Power Up State: US 2-Prong Plug</br> AC Power Cord: 5Ft Detachable Cable</br> item weight: 7 oz. </br> Item Size: 7*2.7*0.9 in </br> DC Output :</br> - 7 way 9v 100ma. </br> - 1 way 9v 500ma. </br> - 1 way 12v 100ma. </br> - 1 way18v 100ma.</br> </br> <b>Connection: </b></br> Included cables use industry standard 5.5mm x 2.1mm positive barrel, negative center polarity plugs.</br> </br> <b>Attention: </b></br> The output ports of this unit is negative central polarity.Incorrect polarity would damage this unit and your devices, please make sure correct positive and negative polarity before wiring. </br> Some pedals may be damaged if poweredusing a voltage that exceeds the level required by the manufacturer, e.g.powering a 9V pedal with 15V or 18V.
