PB-1 is the power supply for guitar effects with regulated 9V direct current (DC). It has eight full galvanically separated outputs which enable to built professional guitar systems without ground loops and crosstalks. SMPS (Switching-Mode Power Supply) technology is applied in the PB-1. The Power Supply does not generate the hum even if it is placed close to the other effects (especially Wah Wahs having inductors). PB-1 enables also to obtain voltages 12V, 15V DC using adapters offered by G LAB and 18V DC using simple to ‘do it yourself’ adapter. PB-1 is worldwide voltage compatible (nominal line voltage from 100V to 230V) by connecting the mains cable (attached to the packet) with a connector appropriate for a given country. It is possible to switch the voltage polarization in outputs no. 4 and 8. The PB-1 package contains labels for cables describing. Showing polarization, energy flow and voltages makes easier to organize the pedalboard and reduce the likehood of effects’ damage caused by faulty connection.Voltage: 9VCurrent: 201-500 mANumber of Outputs: 8Polarity: Center MinusChargerType: AC/DCPlug Type: BarrelPower Supply: 240VMade in: PolandUK/EU Power supply included: NoCurrent (mA): 500.0
